Eight-roll type crusher

Abstract

A disclosed eight-roll type crusher comprises a feed inlet, a broken-stone cylinder and a pedestal; two ends of the pedestal are respectively fixedly provided with a first motor and a second motor; the broken stone cylinder is arranged between the two motors and is fixedly disposed on the pedestal; the upper end of the broken stone cylinder is provided with the feed inlet, the lower end is provided with a tunnel-type material-receiving port, two ends of the upper part outer wall are both provided with a through groove, and two ends of the upper part outer wall are both provided with a through groove; hinges pass through the thorough grooves, and the parts, at the outer wall of the broken stone cylinder, of the hinges are fixed through positioning rollers which are fixedly installed on the outer wall of the broken stone cylinder; the upper part in the broken stone cylinder is provided with four rolls, and the middle-lower part in the broken stone cylinder is provided with four rolls; and two ends of the broken-stone cylinder outer wall are provided with a plurality of discharge ports. The crusher is capable of performing multiple crushing, is capable of reducing powder passing rate and improving resource utilization rate, also is capable of classifying materials with different sizes, is enhanced in functions, steady in operation, small in noise, low in cost and maintenance cost, and relatively long in service life.

Description

technical field [0001] The invention relates to a mining machine, in particular to a roller crusher. Background technique [0002] Crusher is a very common equipment in mines, which can crush ore into required size. In the existing roller crusher, if it is necessary to crush the ore that is too large into small pieces, a large toothed roller surface crusher cannot be used. Due to the need for strength, the teeth on the toothed roller surface cannot be used Small teeth, but the general roller crusher does not have enough strength to crush large ore, the number of crushing is small, the crusher also needs to replace components frequently, the cost of use is high, the work efficiency is low, and the obtained crushed material The fast powder passing rate is high, the size is uneven, and secondary processing is required. Contents of the invention [0003] The object of the present invention is to: aim at the above existing problems, to provide an eight-roller crusher, through...
