Roll extrusion granulator and drum granulator are commonly used granulation equipment, each with its own unique granulation mechanism and application scenarios. The main differences between the two are as follows:

The granulation principle is different

Roll squeezing granulator: Based on the principle of pressure granulation, powder or sheet materials are extruded into continuous strips under high pressure by one or more pairs of rotating rollers in opposite directions, and then cut into particles of the desired particle size. This process is similar to “pressing a cake and cutting it into pieces”.

Drum granulator: utilizing the rolling and stirring effect inside a rotating cylindrical container, adding an appropriate amount of liquid binder to aggregate the material and gradually increase it on the container wall to form spherical particles. This is a dynamic granulation process, similar to a ‘snowball rolling’.

Applicable material types

Roll extrusion granulator: suitable for dry or plastic materials, especially those that can be formed by extrusion, such as mineral powder, chemicals, and some fertilizers.

Drum granulator: more suitable for materials with strong viscosity and good fluidity, such as some organic fertilizers, drugs, and food additives.

Finished product features

Roll granulation: The produced particles have high uniformity, regular shape, and high particle strength, but the shape is relatively flat.

Drum granulation: The produced particles have a more rounded shape and beautiful appearance, but due to the rolling process, there may be some differences in particle size.

Equipment construction

Roller squeezing granulator: The structure is relatively compact, the footprint is small, and the installation and debugging are relatively simple.

Drum granulator: The equipment has a large volume and consists of one or more rotating cylindrical bodies, used for containing and rolling materials.

Energy consumption and cost

Roller squeezing granulator: Due to its granulation process not relying on external heat sources, its energy consumption is relatively low.

Drum granulator: Additional heat or liquid additives may be required, resulting in slightly higher energy consumption and initial preparation costs.

Application scenarios

Roll squeezing granulator: widely used in chemical, fertilizer manufacturing, building materials and other fields, especially in the granulation of hard materials.

Drum granulator: It is widely used in the food processing, pharmaceutical, feed, and fine chemical industries, and is particularly suitable for producing substances that are easy to agglomerate.

Maintenance and operation

Roller squeezing granulator: maintenance is relatively simple, mainly cleaning and lubrication.

Drum granulator: More cleaning and maintenance work may be required, especially to keep the inner wall of the drum clean to prevent material accumulation.

Overall, both roller extrusion granulators and drum granulators have their own advantages and disadvantages. The choice of granulation method should be determined based on specific production needs, material properties, and expected particle characteristics. In practical applications, it is sometimes necessary to combine the advantages of these two methods, such as first extruding the initial shape with a pair of rollers, and then polishing and shaping it with a rotary drum to achieve the desired granulation effect.

Regarding the daily maintenance methods of the fertilizer manufacturing equipment turning and polishing machine, let’s let the turning and polishing machine manufacturers give you a good talk:
Warranty card rules and regulations: The whole machine is guaranteed for half a year from the date of sale. During the warranty period, the following items are not included in the scope of the three guarantees
1. Not used in accordance with the instructions, artificial damage
2. The turning blade is worn and broken
3. The motor burns when water enters. The carbon brush is worn out.
Track-type compost turning machine is currently the most extensive fermentation turning application equipment, including walking wheels, side wheels, and computer control devices, turning parts (also called shifting vehicles, mainly used for double trough or the use of more than double slot). The trackless stacker is driven by rollers, and the width and inner diameter of the groove can be customized according to the user’s different breeding capacity (3-10 meters). When the depth of the turning harrow is not more than 1.3 meters, the wall height is less than 2 meters. The rake turning device is connected with the travel switch through the main shaft. The automatic rake turning machine is suitable for aerobic fermentation, solar fermentation room, fermentation tank and shift car spray equipment, etc. The supporting fermentation tank can continuously discharge materials in batches. The turning and polishing machine has high efficiency, stable operation, sturdiness and durability, low maintenance cost, and simple and convenient remote control operation.

Science and technology are the primary productive forces. With the development of science and technology, the aquaculture industry is constantly developing and changing. We all know that the litter is an important step that needs to be maintained and loosened. After two months of production, it needs to be turned almost every day, otherwise it will cause the fermentation bed to die, causing the feces to be unable to decompose, the fermentation bed to be wet, insects, and frequent diseases. When things happen, the farming technology that can save labor has increased labor. The traditional method is to use manpower to turn the rake with a nail rake. It takes more than an hour for one person to turn all the 20 square meters of litter area at a time, which is laborious and time-consuming and the effect is not ideal. The depth of digging and climbing is generally only 10- 15 cm, the litter cannot be completely broken, the agglomeration cannot be completely scattered, and the real loosening effect cannot be achieved, so the time interval for the next turning rake is relatively short, and the quality of the litter loosening effect directly Decomposing performance of feces to the fermentation bed.

Sheep manure organic fertilizer production line equipment manufacturers are mainly to produce organic fertilizer production machine, organic fertilizer granulator machine, organic fertilizer tipper, organic fertilizer mixer, organic fertilizer screening machine, organic fertilizer drying and cooling machine, organic fertilizer coating packaging machine and other complete sets of organic fertilizer equipment production line, integrating scientific research, production, sales, providing process design, installation, commissioning and personnel training for customers The price comparison of the simple fermentation process of sheep manure was made by the manufacturers.

After stacking, fermentation and turning, the moisture content is reduced to 35-50%. At this time, the sheep manure, also known as fermented sheep manure, is crushed, screened and bagged, and the price is between 150-200 tons / yuan.

Natural fermentation of sheep dung (after secondary fermentation of the stacked sheep manure, turning over the pile for the second time, drying, the moisture content of the fermented sheep manure can be reduced to less than 30%). After bagging, the price of sheep manure produced in this way is 200-300 yuan / ton.

Sheep manure organic fertilizer production line — referring to the natural fermentation method, the organic fertilizer complete equipment is used for one-time fermentation, and the fermentation biological bacteria are added into the fermentation machine. After 7-10 days of composting, and then 10-15 days after the second turning, the fermented sheep manure has no peculiar smell, and probiotics bacteria are added to make the beneficial biological bacteria rapidly propagate in the fermented sheep manure. In this way, after about a month, the beneficial biological bacteria continue to grow and die in the process of reproduction. The dead biological bacteria is the cell protein, and the growing live bacteria are still growing. Through the processing of organic fertilizer equipment production line, such fermented sheep manure has reached the national standard of biological organic fertilizer, which is used in agricultural production, and the effect is several times more than that of natural fermentation sheep manure. The price of packaged compost is higher than that of ordinary compost, and the nutrition is balanced.

When choosing to produce NPK (nitrogen phosphorus potassium compound) fertilizers, whether to use a roller extrusion granulator or a rotary drum granulator depends on various factors, including production scale, raw material properties, cost considerations, and expected product quality. Here is a comparative analysis of two granulation technologies to help you make a more suitable choice:

Advantages of Roll Extrusion Granulator

High particle strength: The particles produced by the roller extrusion granulation mechanism have high hardness and are not easily broken, making them suitable for long-distance transportation and storage.

Flexible operation: Suitable for handling various types of raw materials, including fine powders or materials containing a certain amount of moisture.

Low energy consumption: Compared with drum granulation, roller granulation generally requires less energy input, reducing operating costs.

Small footprint: Compact structure, occupying less space, suitable for factory layouts with limited space.

Good uniformity of finished products: high consistency in granulation size, which is conducive to the uniformity of subsequent packaging and fertilization.

Characteristics of rotary drum granulator

Wide applicability: Suitable for handling materials with strong viscosity, and may have advantages for some raw materials that are difficult to shape by extrusion.

Large capacity production: The rotary drum granulator is suitable for large-scale industrial production and has a large one-time processing capacity.

The finished product is round and beautiful: it is formed by naturally rolling the particles through rotation, with smooth edges and excellent appearance texture.

Strong adjustability: By adjusting factors such as drum speed and tilt angle, particle size and shape can be controlled.

How to choose

Raw material characteristics: If the raw material is delicate or contains a certain amount of moisture, a roller granulator may be a better choice; For situations with strong viscosity and high production requirements, consider using a rotary drum granulator.

Cost budget: Initial investment and operating costs are also important factors, and it is necessary to comprehensively compare the prices, maintenance costs, and energy consumption differences between the two models.

Product requirements: Considering the physical properties of the final product (such as particle strength, shape) and market demand, choose the most suitable granulation method.

Environmental conditions: For small enterprises with limited space, the advantage of occupying space for roller extrusion granulators is obvious; Large manufacturers pursuing mass production may be more inclined towards drum granulators.

In short, each granulation method has its own unique features, and the ideal choice is the one that can best match your specific production needs and conditions. Field visits and consulting with professionals’ opinions can also greatly benefit the decision-making process.

1. Produce bio organic fertilizer by using animal manure. Livestock manure is rich in organic manure, but also contains a certain amount of nitrogen. Phosphorus, potassium and other nutrients needed for plant growth are high-quality raw materials for the production of bio organic fertilizer.

In the fertilizer manufacturing process of bio organic fertilizer, the ratio of dry, humidity and carbon to nitrogen was adjusted by peat and rice bran. Add peat and rice bran to the excrement of livestock and poultry, adjust the humidity of the material to about 50%, remove the non fermentable sundries such as chicken manure, and the width is 2m, which is suitable for production. After fermentation, it is dried and smashed, and then the sundries are screened out. The disc granulator machine is used for granulation, and the biological organic fertilizer is packaged.

2. Use organic waste to produce bio organic fertilize in the biofertilizer project. Organic waste refers to the waste containing substance components in urban and rural domestic waste, mainly including crop straw, fiber, bamboo, waste paper, kitchen residue, etc. If these organic wastes are not treated in time, they will become the pollution sources of the environment, such as stink emission, disease transmission, water pollution and so on.

Therefore, it is necessary to apply organic fertilizer scientifically and reasonably. It makes up for the shortage of NPK fertilizer manufacturing process products. It can not only avoid the adverse consequences caused by its own accumulation and decomposition, but also significantly reduce the environmental pollution caused by the large amount of chemical fertilizer application.

After pretreatment of organic waste, straw was added to adjust the C/N ratio of organic waste, then the moisture content of the waste water was adjusted, inoculated with the fast composting complex microbial inoculum, and fermented at high temperature, then dried at medium temperature.

In terms of equipments required for biofertilizer production, the decomposed materials should be granulated by fertilizer granulator. Then further drying, sieving and packaging can be made into bio organic fertilizer.

The small-scale pig manure organic fertilizer production line aims to convert pig manure, a rich organic resource, into high-quality organic fertilizers, which not only solves the problem of waste disposal in the breeding industry, but also promotes the development of sustainable agriculture. The following is the basic production process of a small-scale pig manure organic fertilizer production line:

1. Raw material collection and pretreatment

Pig manure collection: Collect fresh pig manure from the pig farm in a timely manner to avoid long-term accumulation that can cause odor and pathogen growth.

Remove impurities: Use a sieve or solid-liquid separator to remove large debris such as plastic bags, stones, etc.

Adjusting moisture: Pig manure usually has a high moisture content (up to 80% or more), which needs to be reduced to 40% -60% for fermentation.

2. Fermentation

Mixing auxiliary materials: Adding carbon based materials such as sawdust, straw, and rice husk, adjusting the C/N ratio to 20:1-30:1, is beneficial for microbial activity.

The small-scale pig manure organic fertilizer production line can not only solve the problem of pig manure treatment, but also create economic value and achieve agricultural ecological cycle. However, the production of organic fertilizers requires strict control over all aspects to ensure the safety and reliability of the fertilizers, comply with national organic fertilizer standards, and safeguard the quality of agricultural products and consumer health.

The organic fertilizer turning machine plays a crucial role in the process of processing wet materials (such as livestock manure, kitchen waste, biogas residue, and other high humidity organic waste) into fertilizers. This type of wet material has a high moisture content and is difficult to handle using traditional composting methods. However, organic fertilizer composting machines can effectively address this challenge. The following is the specific processing procedure:

1. Material pretreatment

Dehydration: High humidity materials first need to undergo solid-liquid separation to reduce their moisture content to an appropriate level for subsequent processing. For livestock and poultry manure, an extruder or centrifuge can be used for preliminary dehydration; For kitchen waste, water can be reduced through pressing and other methods.

2. Add auxiliary materials

Mixing water absorbing materials: In order to balance moisture and provide the carbon source required by microorganisms, it is necessary to add auxiliary materials with strong water absorption properties such as straw, sawdust, rice husks, etc., and adjust the carbon nitrogen ratio (C/N ratio) to about 30:1 to promote microbial growth.

3. Early stage of fermentation

Loading: Place the pre processed material evenly on the fermentation bed or in the fermentation tank to form a fermentation pile.

4. Ventilation and flipping

Intervention of compost turning machine: The organic fertilizer compost turning machine uses its specially designed mixing and flipping structure to pass through the material pile, turning the bottom material to the surface while introducing fresh air to ensure sufficient oxygen supply, promote aerobic microbial activity, and accelerate organic matter decomposition.

5. Control temperature and humidity

Temperature monitoring: Continuously monitor the temperature of the stack through internal or external sensors to ensure it remains between 50 ° C and 65 ° C, which is the optimal temperature range for most fermentation bacteria.

Humidity adjustment: During the flipping process, add water moderately or adjust the evaporation of water by flipping to maintain a suitable humidity for the entire stack, neither too wet nor too dry.

6. Regularly flip the pile

Frequent flipping: Every few days to a week, use a organic fertilizer compost turning machine for thorough flipping to ensure that all materials have sufficient aeration and fermentation opportunities, avoiding local overheating or hypoxia.

7. Maturity stage

Observation: As the fermentation progresses, the material gradually becomes dark, odorless, and has a loose texture, indicating that the fermentation is basically complete.

8. Post processing

Crushing and screening: The fermented material is further processed by a crusher to make it smaller particles, which is beneficial for later use.

Drying: Use sun exposure or a dryer to reduce the moisture content of the final product, making it easier to store and transport.

summary

The organic fertilizer turning machine effectively solves the problem of wet material processing by optimizing fermentation conditions, not only improving fermentation efficiency but also ensuring the quality of the final fertilizer. The application of this technology is widely used in the resource utilization of agricultural waste, helping to protect the ecological environment and promote sustainable agricultural development.

Working principle of organic fertilizer turning machine

Organic fertilizer turning machine is a key equipment used for aerobic fermentation of organic waste (such as animal manure, crop residues, food waste, etc.), aiming to accelerate the process of converting these materials into organic fertilizers. Its core working principle is based on the following aspects:

1. Mechanical flipping and ventilation

Flipping: The organic fertilizer turning machine uses a mechanical arm or rotating device to roll the organic materials in the lower part of the heap to the surface, breaking the original stacking structure and promoting mixing and exchange between materials.

Ventilation: During the flipping process, fresh air is introduced into the stack, providing sufficient oxygen to meet the needs of aerobic microorganisms and accelerate the decomposition of organic matter.

2. Temperature and humidity regulation

Heating up: Microbial activity causes the temperature of the heap to rise, and high temperatures help kill pathogens and weed seeds while accelerating the decomposition process.

Moisturizing: During the flipping process, the humidity of the material is controlled to maintain a suitable range for microbial growth, preventing over drying or over wetting.

3. Accelerate decomposition

Microbial activation: Under aerobic conditions, the activity of beneficial microorganisms (such as bacteria and fungi) is enhanced, accelerating the biochemical reactions of organic matter and converting complex organic compounds into simple inorganic salts and humus.
