What is the difference in working principle between slot type and chain plate type turners

Although trough type turners and chain plate turners are commonly used key equipment in organic fertilizer production lines, they have significant differences in structural design and working principles, serving different process requirements. Below is a detailed introduction to the differences between the two:

Trough type stacker

structure characteristics

Fixed channel: The work of the trough type stacker is carried out in a pre built elongated trough, where materials are placed and the trough body is generally fixed.

working principle

Vertical flipping: The trough type flipping machine has one or more sets of mixing shafts, on which flipping blades or other flipping mechanisms are installed. The machine travels along the length direction of the groove, and through the rotating shaft and blades, the material is thrown up and falls back to the bottom of the groove, achieving the flipping and mixing of the material.

Good ventilation: This vertical flipping method can better introduce fresh air, ensure oxygen supply in the compost pile, promote microbial growth and organic matter decomposition.

Chain plate flipping machine

structure characteristics

Chain plate transmission system: The chain plate flipping machine does not rely on fixed channels, but is composed of one or more chain plates with flipping components (such as blades and rake teeth), which are connected in a loop and move back and forth under the drive of a motor.

working principle

Horizontal rolling: The material is placed on the ground or a moving belt, and the chain plate rotates in a loop to push the material from one side to the other, while flipping the material to exchange positions between the upper and lower layers, achieving mixing and ventilation.

Flexible layout: Due to not being limited by fixed channels, the chain plate flipping machine can operate in a more flexible space, with stronger adaptability, especially advantageous for small or irregular sites.

Main differences

Adaptability: Chain plate flipping machine is more flexible and can cope with more diverse on-site conditions; The trough type stacker is more suitable for situations with pre-set trough bodies, especially when dealing with high humidity and high viscosity materials.

Operation mode: The trough type flipping machine relies on the trough wall to support the material, with a large flipping depth, suitable for deep flipping, while the chain plate flipping machine mainly operates on the surface, suitable for lightweight and bulk materials.

Efficiency and Capacity: Due to its fixed structure, the trough type flipping machine has a larger flipping depth and coverage area each time, making it more suitable for industrial large-scale production; Chain plate type is more flexible in small and medium-sized and multi variety processing.

Overall consideration

The selection of which type of stacker to use should be comprehensively considered based on specific production needs, material characteristics, and site conditions. For scenarios that pursue high efficiency and mass production, slot type turntables may be the preferred choice; For diversified processing tasks and applications in confined spaces, the chain plate flipping machine can better meet the needs.
