The working principle of a granulator is to press and shape granular raw materials through a mold. The processing of raw materials usually includes screening, mixing, adding water/oil, etc., and then sending them into a granulator. Under the action of the mold, as the top shaft and mold core rotate, the raw material is gradually compressed into small particles. By using different types of mold cores and pressure rollers, particles of different shapes, sizes, and densities can be produced.
For most granulators, the application industries include food, feed, fertilizers, etc. During the production process, the granulator must have good adjustability and stability to ensure that each particle produced meets the required specifications. In addition, attention should be paid to maintaining the lubrication system during use to prevent early wear of system components due to frictional effects.
High energy consumption: Granulators not only require a large amount of electrical energy, but also require a large amount of compressed air or hydraulic oil transmission devices.
