Vertical pellet mill is mainly composed of feeding, stirring, granulating, transmission and lubrication systems, etc. It is widely used in pharmaceutical, chemical and food industries. Vertical pellet mill can be divided into vertical pellet mill for feed and vertical pellet mill for biomass energy.

Vertical pellet mill is mainly composed of feeding, stirring, granulating, transmission and lubrication systems. Its working process is that the mixed powder with a moisture content of not more than 15% enters the feeding auger from the hopper, and the appropriate material flow is obtained by adjusting the speed of the stepless speed regulating motor, and then enters the agitator, which is stirred with steam by the stirring rod. Mix and temper. If molasses or oil needs to be added, it is also added from the mixing drum and tempered with steam. The amount of oil added is generally not more than 3%, otherwise it is difficult to form. After tempering, the temperature of the powder can reach 64-85 °C , the humidity reaches 14-16%. Then, the iron impurities mixed in the powder are removed through the optional iron suction device through the chute, and finally enter the pressing chamber for granulation.
