Abstract
The invention discloses a mill, which is composed of a frame, an automatic feeding machine, a particle material cylinder, a vibrating feeder, a feeding pipe, a mill, a fan, a material suction pipe, a cyclone separator, a combined shut-off fan, Composed of rotating frame, counterweight, separating screen and soft interface, the upper cover and the main shaft shell of the mill are respectively fixed on the upper and lower sides of the grinding disc shell, the main shaft is installed in the main shaft shell through the bearing, and the lower cutter head is installed on the movable There is a gap between the upper and lower cutter heads and the moving disk, the moving disk and the main shaft are fixed, the upper cutter head is fixed on the fixed seat, and there is a gap between the upper cutter head and the fixed seat, and the grinding disc shell is provided for cooling separately. On the outside of the upper cutter head, between the upper cutter head and the lower cutter head, on the upper air passage, the middle air passage, and the lower air passage outside the lower cutter head, the air outlet is connected to the fan, the fixing seat is connected to the upper cover, and the material inlet is connected to the fixing seat Connected, the present invention has the characteristics of adopting air cooling for the upper cutter head and the lower cutter head, stable rotation, high working efficiency, and automatic matching of eccentric loads.
Description
technical field
[0001] The invention belongs to the technical field of material crushing equipment, and in particular relates to a pulverizer. Background technique
[0002] The pulverizer has been widely used as a material crushing equipment. The mill cutter head of the existing pulverizer is generally provided with a water inlet and a water outlet on the upper cover, and the upper cutter head is cooled by cooling water. If the seal is not good, Leakage is prone to occur, there is no gap between the lower cutterhead and the moving disk, and it is not easy to cool, resulting in high temperature of the lower cutterhead, which seriously affects the output; the rotating frame used is generally the middle part of the main eccentric shaft and the auxiliary eccentric shaft through the bearing seat and fixed The frame is fixed, the end is fixed with the screen rotating frame through the bearing seat, the motor and the rotating frame are fixed, the main eccentric shaft and the auxili...
