Double-layer grinder

Abstract

The invention relates to a double-layer grinder grinding twice, overcoming the disadvantages that an upper-layer grinder structure and a lower-layer grinder structure are connected by a main shaft and mainly bear abrasion and extrusion forces, and the equipment has larger pressure in the prior art. The double-layer grinder comprises a cylinder body in which a grinding chamber and a rotating shaft are arranged, a grinding cutter is fixed on the rotating shaft, the positions of the inner wall of the cylinder body corresponding to a cutter frame shaft and a teeth-cutter shaft are respectively fixed with a claw cutter and a teeth cutter, the claw cutter is provided with a cutter claw extruding into the gap between the grinding cutters on the cutter frame shaft, and the teeth cutter is provided with cutter teeth extruding into the gap between the cutters on the teeth-cutter shaft. Firstly, the grinding cutter on the cutter frame shaft performs crude grinding, and then the grinding cutter on the teeth-cuter shaft performs fine grinding, thus lightening action force borne by parts during grinding every time and slowing abrasion of the parts so as to prolong the service life.

Description

technical field [0001] The invention relates to a crushing mechanical device, in particular to a double-layer crushing machine for double crushing. Background technique [0002] Tens of thousands of years ago, the ancient apes knew how to use stones to break the materials and food they needed in order to survive. With the progress of society, humans used the lever theorem to make rice pounders, and used the principle of friction and extrusion to make stone mills... ...all for the purpose of turning large particle materials into required granules or powder materials, and with the rise of the European industrial revolution and the needs of various product materials, various types of pulverizers have emerged as the times require. The external forces applied to the solid during the pulverization process include rolling, shearing, impact, and grinding. These pulverizers generally only have one pulverization, that is, only one layer of pulverization. After the material enters from...
