Problems solved by technology

[0007] The disadvantage of the traditional horizontal structure (the surface of the grinding disc is perpendicular to the horizontal plane) is that the material between the convex lobes of the fixed grinding disc lacks geometric constraints, which leads to a decrease in the pressure of the processing cavity and the backflow of the material.
As a result, the rotation of the movable grinding table cannot drive all the materials entering the grinding table to be fully crushed, and the lamination crushing and shearing crushing capabilities are low, which affects the particle size of the prepared sample

Embodiment Construction

[0025] A disc pulverizer includes a movable grinding disc 1 and a fixed grinding disc 2 . Two bosses 4 are arranged on the center plane of the processing chamber 3 of the movable grinding disc 1 . There is a throwing groove 5 between the two bosses 4, and the width of the throwing groove 5 is not less than the diameter of the feeding hole of the fixed grinding disc 2. Two convex petals 6 are arranged on the outer side of the boss 4, and the convex petals 6 are symmetrically distributed on a straight line. The top curved surface of the boss 4 is a conical surface, and the outer surface is a cylindrical surface. The conical surface at the top of the boss 4 is parallel to the conical surface of the fixed grinding disc 2, and the diameter of the outer cylindrical surface is equal to the diameter of the top conical surface. The prepared material enters the processing chamber 3 through the feeding hole on the fixed grinding disc 2, and the moving grinding disc 1 rotates around the...

Abstract

The invention discloses a disc mill which comprises a movable milling disc (1) and a fixed milling disc (2), two bosses (4) are arranged on a central plane of a processing material cavity (3) of the movable milling disc (1), a material throwing groove (5) is arranged between the two bosses (4), and protruding petals (6) are arranged on the outsides of the two bosses (4). The disc mill has the advantages of overcoming the defect that the movable milling disc of a horizontal type disc mill cannot drive all materials to be sufficiently smashed, lamination smashing along a circumferential normal direction in the processing material cavity of the milling disc is achieved, processed materials can be finely smashed, and a choice is provided for optimizing the disc mill.

Description

technical field [0001] The invention relates to a crushing device, in particular to a grinding disc of a disc grinder. Background technique [0002] The disc pulverizer is the equipment specified in the gold ore sample crushing process in DZ / T 0130.2-2006 "The People's Republic of China Geological and Mineral Industry Standards - Preparation of Rock and Mineral Analysis Samples". Its main working parts are composed of movable grinding disc and fixed grinding disc. The fixed grinding disc is connected with the body, and the feeding hole of the fixed grinding disc communicates with the feeding channel on the body. The moving grinding table is connected with the transmission spindle on the machine body, and a fine-tuning locking device is installed on the transmission shaft, which can fine-tune the moving grinding table in the axial direction, so as to ensure that the discharge gap between the moving grinding table and the fixed grinding table meets the particle size requireme...
