Mineral product crusher capable of adaptively adjusting crushing amount

Abstract

The invention relates to the technical field of mineral product equipment, in particular to a mineral product crusher capable of adaptively adjusting the crushing amount. The crusher comprises a shell, a transmission shaft, a plurality of grinding plates and a plurality of groups of stop blocks, a grinding space is divided into a first-stage grinding cavity and a second-stage grinding cavity by the grinding plates, a material passing opening is formed in each grinding plate, an inner cutter is arranged on the stop block at the inner side, and an outer cutter is arranged on the stop block at the outer side. When the first-stage grinding cavity is blocked, the inner cutter enables the stop block to rotate under the resistance of mineral product raw materials, so that the opening degree of the material passing openings is increased, and the resistance of the first-stage grinding cavity is reduced; when the second-stage grinding cavity is blocked, the outer cutter enables the stop block to rotate under the resistance of the mineral product raw materials, so that the opening degree of the material passing openings is reduced, and the resistance of the second-stage grinding cavity is reduced; and therefore, the crushing amount of the first-stage grinding cavity and the second-stage grinding cavity is automatically adjusted through the grinding resistance, stockpiling jamming is avoided, meanwhile, the phenomenon that a motor carries out forced driving for crushing during jamming is avoided, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of mineral equipment, in particular to a mineral crusher for self-adaptive adjustment of crushing capacity. Background technique [0002] Mining refers to the exploitation of valuable natural mineral resources by manual or mechanical means. Minerals mined from mines have a large number of useful components or have certain properties that can be used. After the minerals are collected from the mines, they can be used in the metallurgical industry and the chemical industry after being processed step by step by crushing and grinding. , construction industry, railway (road) road construction units, cement industry and sand and gravel industry and other engineering fields, so crushers are essential in mining. [0003] Most of the existing mineral crushers have a single structure and only undergo one crushing and grinding process. The grinding chamber is easily jammed by stacking materials. In severe cases, the eq...
