Servo-driven three-cutter mechanical shock high-speed grinder

Abstract

The invention relates to a servo-driven three-cutter mechanical shock high-speed grinder which comprises a frame; a smashing device is fixedly arranged at the center of the frame; a grading device isfixedly arranged on the top of the smashing device; the smashing device is composed of an outer rotor servo motor and three rotary cutters; the outer rotor servo motor is used for directly driving a second cutter and utilizes two planetary gear trains to drive a first cutter and a third cutter, so that the first cutter and the second cutter are rotated along the opposite directions and the secondcutter and the third cutter are rotated along the opposite directions. The servo-driven three-cutter mechanical shock high-speed grinder is capable of effectively increasing the relative impact velocity of grains and cutters, forming an anti-abrading material layer on the third cutter surface, delaying the abrasion of the cutters and prolonging the service life of equipment, and has the advantagesof compact structure, high smashing efficiency and convenience in operation.

Description

technical field [0001] The invention belongs to the technical field of pulverizers, in particular to a servo-driven three-cutter mechanical impact high-speed counter-grinding pulverizer. Background technique [0002] The preparation of ultra-fine powders for lithium-ion battery electrode materials is a key link in the production process of lithium-ion batteries. At present, the commonly used electrode material powder crushing equipment in the industry is a mechanical impact mill, which is mainly composed of the internal moving plate of the mill, Composed of a fixed plate and a classifying wheel, the moving plate and the fixed plate are equipped with blades, and the material is crushed under various forces such as repeated friction, impact, shearing, extrusion, etc. between the high-speed rotating moving plate and the fixed plate, and meets the particle size The required products go out through the louver classifier and enter the cyclone separator and dust collector for colle...

AI Technical Summary

Problems solved by technology

[0004] 1. The power source of the mechanical impact mill is generally connected to the main shaft of the cutterhead by belt transmission, which occupies a large area and has low transmission efficiency. Especially when the transmission is high-speed, unnecessary torque loss will be generated due to wind resistance, and the service life of the belt is relatively long. Low

[0005] 2. The speed of the cutter head is limited by factors such as the transmission mode, the dynamic balance of the cutter head and the limit speed of the bearing, which is difficult to increase, and the crushing efficiency is limited.

[0006] 3. The crushing area is mainly concentrated in the ring area at the edge of the cutterhead. For cutterheads with larger diameters, the effective crushing area is relatively small, and the central space of the cutterhead cannot be fully utilized.

[0007] 4. The feeding port is set on the edge of the cutter head, and the acceleration effect of the cutter head on the particles is limited
