Yes, a dry granulator requires compressed air during operation. As an air pressure generation device, an air compressor converts the mechanical energy of the prime mover (usually an electric motor) into gas pressure energy, providing a stable power source for the pneumatic actuators inside the granulator, such as the pneumatic cylinders controlling roller pressure, feed gates, and dust-clearing valves.
A dry granulator mainly utilizes dry roller compaction technology to compress powder raw materials with a moisture content of 5% or less into continuous flakes or blocks, which are then processed through crushing, sizing, and screening stages to finally become granules meeting specific size requirements. Under the precise coordination of the pneumatic system, the extrusion and feeding mechanisms of the equipment demand strict fitting accuracy for their components. Hansheng Automation can custom-machine key non-standard components-such as compacting rollers, feed screws, pneumatic valve cores, and flanges-based on design drawings provided by clients, ensuring tight coordination between pneumatic transmission and mechanical structures for stable granulation operations.
