Abstract

The invention relates to a crusher which comprises a drive device, a driving shaft, a driven shaft, a transmission mechanism, rollers, a feed inlet, a feed outlet and a bracket, wherein the transmission mechanism comprises a driving tire and a driven tire; one end of the driving shaft is connected with the drive device, and the other end of the driving shaft is connected with the driving tire; the driven shaft is connected with the driven tire; the driving tire and the driven tire are mutually matched tightly; the rollers are respectively sleeved on the driving shaft and the driven shaft tightly; and straight teeth are fixed on the rollers. When the two rollers move relative to each other, materials entering the crusher are extruded, so that material particles are smaller, and the material particles smoothly enter an equipment body. The crusher has the advantages of large and adjustable transmission force, little damage to the equipment, smooth and safe operation, low noise, easy cleaning and no material residues.

Description

technical field [0001] The invention relates to a crusher, in particular to a double-roll crusher used for crushing coal, ore and other bulk goods for sample analysis. Background technique [0002] The main application fields of the roller crusher are the crushing process of sample preparation and inspection of ores, minerals, metallographic samples, ceramic products, soil, mixtures, chemicals and similar materials, which is an important link in the sampling inspection process. [0003] When conducting international and domestic trade transactions of ores, minerals and other bulk cargoes, it is necessary to conduct strict quantitative analysis on the entire delivery batch to determine the quality of the delivery batch. For the accuracy and representativeness of the quality identification of the delivery batch, the sample preparation process plays a very critical role. The crusher is one of the key equipment to achieve the required particle size according to the required cru...
