Annular crusher for massive materials

Abstract

The invention provides an annular crusher for massive materials, which is characterized in that the bottoms of brackets I are fixed on bases; bearing seats are fixed on the tops of the brackets I; both ends of a shaft are installed in the bearing seats by bearings; an input end is connected with an output end of a driving device by a shaft coupler; a pull rack is fixedly connected with the middleof the shaft by a plurality of supporting legs; a plurality of hitting rings are hung on a pin shaft whose both ends are fixed in a hole of the pull rack; sliding ways are positioned on the side close to the materials for the bases between the two brackets I; the width is larger than the axial width of the hitting rings; the sliding ways are bent downwards in an arc shape; and the lower surfaces of the bases are provided with a plurality of self-alignment truckles and supporting truckles. The invention provides mechanical equipment for crushing massive materials, and the proportion of powderymaterials after crushing is low; and the crusher can also alleviate labor intensity of workers and control the axial position of a hitting device to enable a hitting process to be accurate and reliable.

Description

technical field [0001] The invention provides a ring-type bulk material crusher, specifically a machine that uses a rotating ring-shaped weight to crush the super-large block abrasives used in the grinding wheel and abrasive tool industries, and the ultra-large block stones used in the mine and building material industries. equipment. Background technique [0002] Various abrasives such as alumina, white corundum, etc., are the main raw materials for the production of grinding wheels and other products. In the production process of these abrasives, they are generally made into huge blocky semi-finished products through sintering and other processes, and then they are broken step by step and processed into small block-shaped finished products before leaving the factory. [0003] Since it is an abrasive used in the manufacture of grinding wheels and other products, its hardness is of course very high, so of course the force required for crushing is also very large. Commonly u...

Problems solved by technology

However, in the large block material crusher involved in this patent, the axial swing of the hammer along the rotary shaft is not easy to control when striking, and the striking point is not accurate enough.
