Roller disc grinding crusher

Abstract

The invention relates to a roller disc grinding crusher for crushing of metal minerals, industrial minerals, chemical minerals and energy minerals. The roller disc grinding crusher mainly consists ofsuch parts as grinding rollers (2), a grinding roller frame (3), a pivot shaft (4), a grinding disc (6), a motor (8), a hydraulic cylinder (13) and a speed reducer (14). The surface of the grinding disc (6) is conical; the cone angle delta is 120-179 degrees; a projected flange (63) is arranged at the outer periphery; a material layer (5) is formed thereon; and one grinding disc is provided. The grinding rollers (2) are positioned above the grinding disc (6), are supported on the grinding roller frame (3) in a simple support beam support manner, are pressed on the grinding disc (6) by the hydraulic cylinder (13) through the grinding roller frame (3) with the pivot shaft (4) as a fulcrum, and are driven to rotate by the grinding disc (6). The grinding rollers (2) are conical; the cone angles gamma of the conical surfaces are 1-60 degrees; the ratios of the lengths to the large end diameters are larger than or equal to 1; and 1-10 grinding rollers are provided. The roller disc grinding crusher is higher in efficiency compared with a cylindrical grinder, and is simpler in structure and convenient to operate and maintain compared with a high-pressure roller grinder.

Description

technical field [0001] The invention relates to a roller-disk grinder used for crushing metal minerals, industrial minerals, chemical minerals and energy minerals. Background technique [0002] In the crushing operations of metal minerals, industrial minerals, chemical minerals and energy minerals at home and abroad, the crushing equipment widely used for a long time is gyratory crushers, cone crushers, jaw crushers and barrel mills (including rod mills, ball mills) , autogenous and semi-autogenous mills). Since the barrel mill is a probabilistic crushing equipment, the crushing probability is low, and most of the input energy is consumed in the process of heat generation, sound generation and vibration. The efficiency of the grinding process is low, and less than 5% is used for grinding, resulting in these crushing The process efficiency of equipment composition is low, and the crushing energy consumption is high. In recent years, efficient and energy-saving high-pressure...

Problems solved by technology

Since the barrel mill is a probabilistic crushing equipment, the crushing probability is low, and most of the input energy is consumed in the process of heat generation, sound generation and vibration. The efficiency of the grinding process is low, and less than 5% is used for grinding, resulting in these crushing The process efficiency of equipment composition is low, and the crushing energy consumption is high

In recent years, efficient and energy-saving high-pressure roller mills have entered the field of mineral processing, but the equipment structure of high-pressure roller mills is complex, the requirements for crushing conditions are relatively strict, and the operation requirements are relatively high.

This field lacks a kind of crushing equipment that not only has high crushing efficiency, but also is more convenient to operate and maintain.
