Periodic material crushing and grinding device

Abstract

The invention discloses a periodic material crushing and grinding device, and relates to the technical field of material grinding. The periodic material crushing and grinding device comprises an innershell; a pre-pressing cavity, a discharging cavity and a grinding cavity are sequentially formed in the inner shell, a movable ball is arranged on the inner wall of the pre-pressing cavity, cutting boards are arranged on the outer side of the movable ball at equal intervals, a plug rod is fixedly connected to the center of the top of the movable ball, protruding thorns are arranged on the surfaceof the movable ball and located between the cutter boards and the plug rod at equal intervals, the top of the pre-pressing cavity communicates with a feeding pipe, a movable plug is movably connectedto the inner wall of the discharging cavity, an ejector rod is arranged in the center of the top of the movable plug, and a grinding block is rotationally connected to the outer end of a connecting rod. According to the periodic material crushing and grinding device, the problems that at present, grinding devices on the market are various in type, but generally, a large number of materials are stacked and then ground in a centralized mode, the grinding efficiency is low, the discharging uniformity is poor, and high-precision material grinding machining and using are difficult to achieve are solved.

Description

technical field [0001] The invention relates to the technical field of material grinding, in particular to a periodic material grinding and grinding device. Background technique [0002] Material grinding refers to the reciprocating movement of large particles through a grinding tool under a certain pressure, and finally obtains a small particle powder that meets the demand. It belongs to the fine processing process of granular materials and is widely used in various industries. At present, there are many types of grinding devices on the market, but generally a large amount of material is piled in, and then concentrated grinding is performed. The grinding efficiency is low and the uniformity of the material is poor, which is difficult to meet the high-precision material grinding process. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides a periodical material crushing and gr...
