Crushing machine

Abstract

The invention provides a crushing machine. The crushing machine comprises a transmission gear, a feeding hopper, a box body, a bearing pedestal rack, a machine base, a coupler, a speed reducer bracketand a power device, a crushing machine can achieve distance control through a clearance control device, and a speed reducing system achieves two-stage speed reducing. According to the crushing machine, an alloy plate with the polished surface is designed on a moving bearing pedestal rack sliding way, therefore, a moving bearing pedestal can flexibly slide on the sliding way, and the distance between crushing rolls can be flexibly adjusted by combining the clearance control device; the speed reducing system achieving two-stage speed reducing is adopted and combined with a V-shaped belt, therefore, transmission is more steady, operation such as assembling, disassembling and overhauling is easy and convenient, and noise is low; the crushing rolls are provided with multiple rectangular pyramid frustum teeth made of a high manganese steel material obtained through heat treatment machining, therefore, the life of tooth rolls is long, and combining overall running of the crushing machine, the crushing machine overall has the advantages of being high in wear resistance, high in crushing efficiency and uniform in product particle size; and in addition, moving is convenient, energy consumption is low, and the application range is wide.

Description

technical field [0001] The invention relates to the field of crusher preparation, in particular to a crusher. Background technique [0002] Our country is very rich in ore and coal resources, and there are many enterprises producing crushed stone. In many industrial sectors such as construction and road construction, coking plants, sintering plants, ceramic plants, glass industry, powder metallurgy, etc., there are a large number of raw materials and recycled materials every year. The waste is processed by a crusher. For example, in a cement plant, in order to burn the raw materials into clinker, the raw materials should be broken into pieces first, and then the clinker should be ground into cement with a rock mill after burning the clinker. Another example is the mineral processing plant, which uses a crusher to crush the raw ore to the particle size required by the grinding process so that the useful minerals in the ore can be separated from the monomer, or the raw materia...

Problems solved by technology

The crushing work gap control is the key parameter of the crusher. The crushing work gap is related to the results of the crushing work, such as particle size, processing capacity, etc. It is even related to the stability of the crusher and the service life of parts, especially in crushing. When the machine works continuously, wear will occur, and its wear will be uneven due to factors such as material conditions, which will not only affect the crushing quality but also affect the crushing efficiency

In addition, if the general crushing equipment stops working, the entire production line or even the entire factory may have to stop working, affecting the production process.

[0003] The crushers in the prior art cannot strictly guarantee the particle size of the product, the crushing force is difficult to control, the phenomenon that the product is easily over-crushed is serious, and the noise is large; the material contains more hard and difficult to break, and the equipment is easily damaged; the existing crushing methods exist A certain crushing limit, high energy consumption, inconvenient maintenance, large amount of maintenance, fragile crushing teeth, low production efficiency

[0004] A kind of crusher, there are still many practical problems to be solved urgently in its practical application, and no specific solutions have been proposed
