Chopping block type comb-shaped shear crushing device

Abstract

Disclosed in the present invention is a chopping block type crushing device with comb cutting edge adapts for double toothed roll crusher fundamentally, which overcomes the drawbacks of easy plugging material, supporting instability etc.of the existing toothed roll crusher. The technical point is: omitting a original cutting sieve plate fixed usually on a guiding plate in the existing toothed roll crusher, using a support seat with an arc-shaped guiding surface to replace the original single plate, using a comb cutting edge arranged uniformly and fixed on the comb toothed chopping block to replace the guide cutting vertical plate of the original cutting sieve plate. Especially the gap of the comb tooth chopping block is arranged to cross with the gaps formed between two adjacent comb toothed edges , which makes the material cut again when the cutting tooth of the first and second toothed roll rotors pass through the corresponding gap. Compared with similar products, the device is more rational in design, scientific in structure matching and it is easy to manufacture, install and maintain. The service life of the device is further prolonged, the crushing efficiency is distinctly improved , the scope of the application is broaden, and the requirement of the various toothed roll crusher for crushing the material discharging granularity can be absolutely met.

Description

technical field [0001] The invention relates to a secondary crushing device used in conjunction with a crusher, in particular to an anvil-shaped comb-shaped cutting blade crushing device suitable for double-toothed roller crushers, and can also be used for other toothed roller crushers for flexible Re-crushing of materials. Background technique [0002] At present, with the development of crushing technology and the adaptation to the requirements of the discharge granularity and operating efficiency of the crushed materials, various crushing equipment have come out one after another. In recent years, people's awareness of environmental protection has been continuously strengthened and many domestic biological power plants have been launched, so that the originally discarded agricultural and sideline products have been developed and fully utilized. However, due to the short crushing stroke of the traditional double-toothed roller crusher, the materials cannot be crushed into ...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide an anvil-type comb-shaped cutting blade crushing device suitable for double-toothed roller crushers, which fundamentally solves the problems of easy blockage, Support instability and other defects, compared with similar products, its design is more reasonable, the structure matching is scientific, greatly improving the supporting strength, easy to manufacture, install and maintain, further prolonging the service life of the equipment, significantly improving the efficiency of crushing operations, and broadening the scope of application , fully meet the requirements of various toothed roller crushers for the output particle size of crushed materials
