Description

Technical Field

[0001] The utility model relates to the technical field of distributors, and more specifically, to an anti-blocking and crushing front distributor. Background Art

[0002] Crushing is the process of applying external force to the material to be crushed, overcoming the cohesive force between the material molecules, and splitting the large piece of material into several small pieces. Crushing operations are divided into mechanical energy crushing and non-mechanical energy crushing such as electrical energy, thermal energy, etc. according to the different forms of energy consumed. In industry, mechanical force is mainly used for crushing. There are several methods: crushing, splitting, breaking, grinding, impact crushing, etc.

[0003] When finer materials are needed, it is usually necessary to first perform coarse crushing on the materials and then perform fine crushing on them through a fine crusher. The materials crushed by the fine crusher will contain larger materials, which is not convenient for crushing larger materials. Larger materials are easy to damage the fine crusher and easily cause materials to be blocked at the feed port of the fine crusher. Therefore, it is necessary to install a pre-feeder at the feed port of the fine crusher, and separate larger materials from smaller materials through the screening structure in the pre-feeder. Larger materials will accumulate above the screening structure, which is not convenient for cleaning and is easy to cause blockage of the screening structure. When the screening structure fails, it is not convenient to disassemble and replace it. Utility Model Content
