Description

Crushing component device for crusher

Technical Field

The utility model belongs to the technical field of the rubbing crusher is made, concretely relates to crushing unit device for rubbing crusher.

Background

The crusher is a machine for crushing large-size solid materials into required sizes, generally mixes solid and liquid during crushing, and is widely applied to the fields of chemical industry, metallurgy, plastics, food, pharmacy, building and the like. The coarse crusher is mainly used for crushing pretreatment operation in various industries and mainly has the function of processing materials with larger diameters into granular materials with smaller diameters. The external forces applied to the material in the crushing process include rolling, shearing, impacting (beating) and grinding. The rolling is mainly used for coarse crushing and medium crushing, and is suitable for crushing hard materials and large lump materials; the shearing is mainly used for crushing or crushing, and is suitable for crushing of tough or fibrous materials; impact (beating) is mainly used for crushing and depolymerization, and is suitable for crushing of brittle materials; the grinding is mainly carried out by superfine grinding and superfine grinding, and is suitable for superfine grinding after medium-fineness grinding. The existing crusher is mainly an impact crushing method, such as crushing materials by using free rolling metal balls or crushing materials by using relative motion of a movable hammer body rotating at a high speed and fixed gear rings around, so that the materials are impacted and rubbed by hammer teeth to impact each other. Since the impact type crushing method requires repeated impact on the impact material, the crushing efficiency is low, and a large-sized crusher needs to be manufactured if a large amount of material crushing operation is to be dealt with. Because the impact object can not be selected, the target is random, the materials after multiple impacts are changed into fine powder far smaller than the target granularity, the impacted materials are far larger than the target granularity for a few times, and the materials are not impacted until the impact is still carried out. Therefore, the prior art pulverizer has the following defects: firstly, the crushed materials are different in size and very uneven, and the content of fine powder is high. However, in some fields, uniform material particles are required, for example, in the plastic molding industry, plastic raw material particles are required to be melted at a uniform temperature, because the plastic needs to be melted during molding, the melting temperature of the small particles is low, and the particles naturally need to be melted completely at a higher temperature or in a longer time, so that the uneven distribution of the plastic raw material particles is not beneficial to molding. The plastic produced by the plastic petrochemical industry is a mixture of blocks with different sizes of 0.2 to 20mm and other liquid reagents, and because the prior crushed particles are uneven and have higher fine powder content, granulation processing similar to extrusion molding is required before plastic molding to form uniform plastic particles. The prior art pulverizer has the second defect that the equipment occupies large area and has low pulverizing efficiency.
