Unit roll-disk breaker

Abstract

A unit-type roller-disk pulverizer is composed of an annular grinding disk made up by embedding a flat lining plate on the annular flat bed car on an annular track, an annular machine frame, a toothed ring linked via gear to power mechanism, and 2-10 grinding units on said annular grinding disk. Said grinding unit consists of 2-6 grinding rollers with hydraulic cylinder at its both ends, pulverized material layer controller, unloader, plate cleaner for grinding roller, and material collecting small scraper.

Description

technical field [0001] The invention relates to a crusher for ores and materials in various mines and building materials industries, especially a roller disc crusher; it is especially suitable for continuous and efficient crushing of ores and materials less than 70mm in size, and is very useful in large-scale enterprises such as mines and building materials industries. it works. Background technique [0002] Roller disc mills generally include two types of disc-driven and roller-driven, for example: the "roller disc crusher" described in ZL93215042.X and the "roller mill" described in US15034920. In the prior art, whether it is a disc-driven pulverizer or a roller (wheel)-driven pulverizer, its disc and roller (wheel) are limited by the following factors, such as small crushing ratio, fine particles in the pulverized product Grade content is low, and it is difficult to meet the particle size requirements of ball mill discharge (for example, -200 mesh particle size content i...

Problems solved by technology

In the prior art, whether it is a disc-driven pulverizer or a roller (wheel)-driven pulverizer, its disc and roller (wheel) are limited by the following factors, such as small crushing ratio, fine particles in the pulverized product The grade content is low, and it is difficult to meet the particle size requirements of the ball mill discharge (for example, the -200 mesh particle size content in the discharge exceeds 20%), so it can only replace the fine crusher, but not the ball mill at the same time.

Due to its equipment characteristics, it is difficult to adapt to materials and ores with high moisture content, so it cannot process materials and ores in various mines and building materials industries; and this type of pulverizer is complicated to manufacture, so it is expensive and can only be used in used in a few factories

Therefore, they are still unable to adapt to the actual needs of large-scale production of various mines, building materials industries and other large-scale enterprises.

According to relevant surveys, ball mills, rod mills, and autogenous mills are still the main crushing machines used by large mines and building materials industries at home and abroad for medium and fine-grained ores and materials. The extremely high crushing costs of these crushing machines have always been Plaguing businesses and desperately in need of an update
