Disc type grinding device for machining heavy calcium carbonate

Abstract

The invention discloses a disc type grinding device for machining heavy calcium carbonate. The disc type grinding device comprises a stirring cavity, a motor, a bottom plate, grinding balls, grindingdiscs, a transmission cavity and a shell, wherein the stirring cavity is formed in the upper end of the inner side of the shell, a motor is arranged at the middle position of the upper end of the shell, the output end of the motor is fixedly connected with a rotating shaft, the rotating shaft penetrates through the upper end of the shell and extends into the stirring cavity, and the bottom plate is arranged at the lower end of the stirring cavity; and the grinding discs are fixedly installed at the lower end of the inner side of the shell, annular grinding grooves are formed in the upper endsof the grinding discs, the grinding balls are symmetrically arranged above the annular grinding grooves, and the grinding balls are fixedly installed on a U-shaped supporting rod. According to the disc type grinding device, the design is novel, an ejector rod is driven to reciprocate up and down through a push rod when a movable block moves left and right, the ejector rod drives the grinding ballsto move up and down through the U-shaped supporting rod, so that the heavy calcium carbonate on the side edge of the grinding balls slides to the bottoms of the grinding balls, and then the grindingefficiency is improved.

Description

technical field [0001] The invention relates to a grinding device, in particular to a disc grinding device used for processing heavy calcium carbonate. Background technique [0002] Ground calcium carbonate is a classification of calcium carbonate. Since ultrafine ground calcium carbonate can be closely related to modern polymer-based composite materials, plastics, rubber, adhesives, paint coatings, advanced paper, fillers and pigments, etc., in recent years The market demand continues to expand, and it has become one of the largest industrial mineral raw materials used by the global paper and plastic industries. [0003] At present, the grinding machine is a very critical equipment in the production process of ultra-fine ground calcium carbonate. The working performance of the grinding machine directly affects the product quality of ultra-fine ground calcium carbonate. Continuously adding raw materials manually for grinding process consumes manpower and has a low degree of...

Problems solved by technology

[0003] At present, the grinding machine is a very critical equipment in the production process of ultra-fine ground calcium carbonate. The working performance of the grinding machine directly affects the product quality of ultra-fine ground calcium carbonate. Adding raw materials manually for grinding process consumes manpower and has a low degree of automation. Manual addition is easy to add too much raw material for grinding. Too much raw material is put into the grinding chamber, which affects the grinding effect of the grinder.
