Multi-surface roller type crusher

Abstract

The invention relates to a multi-surface roller type crusher. The multi-surface roller type crusher is characterized in that a multi-surface roller (6) is installed in a crushing cabin (5); the roll surfaces of the multi-surface roller (6) are formed by successively connecting multiple planes end to end; each end surface of the multi-surface roller (6) is of an equilateral polygon with 3-8 edges; multiple steel rails (4) are arranged on the planes of the roll surfaces of the multi-surface roller (6) and the inner walls of the crushing cabin (5), or multiple steel rails (4) are only arranged on the planes of the roll surfaces of the multi-surface roller (6), or multiple steel rails (4) are only arranged on the inner walls of the crushing cabin (5); and the multiple steel rails (4) on the planes of the roll surfaces of the multi-surface roller (6) or on the inner walls of the crushing cabin (5) are respectively crossed to form triangular or quadrangular grids. The multi-surface roller type crusher has friction force and extrusion breaking force which are larger than those of a common round roller, the crushing ratio can reach 15-20, and the multi-surface roller type crusher is especially suitable for crushing of middle-hardness ore materials such as iron ore, gypsum, sandstone, blast furnace slag and lump coal.

Description

technical field [0001] The invention relates to a crusher, in particular to a multifaceted roller crusher. Background technique [0002] At present, the single-roll or multi-roll crushers commonly used in the metallurgy and building materials fields generally use cylindrical sticks, and some materials slip during the rolling process, which affects the crushing efficiency and crushing effect. [0003] In addition, during the material crushing process of the single-roll crusher, the jaw plate and the roller need to interact and squeeze the material. The jaw plate must be inlaid with wear-resistant and expensive liners, and because the liners need to be replaced frequently, the maintenance work The larger the quantity, the higher the maintenance cost. Contents of the invention [0004] The invention provides a multifaceted roll crusher, which has the advantages of simple structure, small volume, less supporting equipment, convenient operation and low operation cost, so as ...
