With increasingly stringent environmental protection policies, fertilizer companies must not only maintain production capacity but also meet the green requirements of “low dust, low noise, and low energy consumption.” As the core equipment in the production line, the ring die granulator’s operation directly impacts environmental performance.
First, dust source control. The ring die granulator’s fully sealed feed and discharge structure reduces dust spillage. The feed inlet utilizes a “soft-connected sealing sleeve” to prevent raw material leakage during conveying; the discharge outlet connects to a “sealed cooler,” ensuring pellet cooling within a sealed space.
Second, effective noise reduction is required. Mechanical friction and raw material impact during operation of the ring die granulator can easily generate noise, impacting the workshop environment. During routine maintenance, regularly checking the lubrication of the roller bearings and tightening the bolts connecting the ring die to the frame can reduce operating noise to below 75 decibels.
Third, optimizing energy consumption is essential. Green operation of the ring die granulator can be achieved through variable frequency speed regulation. Adjust the ring die speed according to the raw material characteristics and production needs to avoid the motor idling at full load; at the same time, regularly clean the residual raw materials in the ring die hole to ensure that the equipment always operates in the “high efficiency and low consumption” range.
