The disc granulator machine is widely used, not only in the organic fertilizer production process but also in the granulation work of the npk production line and the bio organic fertilizer production. The operation of the disc granulator involves paying attention to the upstream processing conditions and understanding how different variables interact with each other. Acts to affect the product coming off the disc.
1. Disc speed
Disc speed refers to RPM, or the rate at which a disc spins. Speed is regulated by a variable frequency drive (VFD), which gives the operator more control over speed regulation during startup and shutdown, or during surges. Speed is the least important variable and is used only with angle adjustment to obtain optimum material coverage on the granulator (material should cover the entire pan when the spray system is off).
2. Disc angle
The angle of the pot is adjusted by the jacking screw of the hand wheel. In a way, angle and speed adjustments are free. The steeper the angle of the pan, the faster the speed required. Higher angles result in shorter dwell times on the disc, producing smaller particles.
