High falling crushing device

Abstract

A high-fall crushing device, comprising: a falling channel (1) having an inlet and an outlet, an input device (4) for transporting bulk materials into the inlet, arranged at the outlet and used for crushing The output device (5) from which the material is transported. The falling channel (1) is provided with multiple layers of gratings (2) that are crushed after the material hits, and the gratings (2) of each layer are arranged in the falling channel (1) at intervals of a predetermined crushing height. , the grid hole size of the grid (2) in the upper layer is larger than the grid hole size of the grid (2) in the lower layer, and each layer of grid is provided with a discharge mechanism. The invention uses the grid as the impact body, and the material is crushed after colliding with the grid. Due to the screening function of the grid, the size of the output material is uniform, and subsequent screening is not required, and the operation is simple.

Description

technical field [0001] The invention belongs to the field of crushing devices, in particular to a high-falling crushing device Background technique [0002] In production practice, people often need to crush materials for use. For example, stones obtained from mountain blasting often need to be crushed and crushed by jaw crushers, cone crushers and other machinery in order to meet the requirements of industrial and mining enterprises for the use of stones. However, the above-mentioned traditional crushing mechanism has the defect of high energy consumption. According to statistics, about 2% of the world's electric energy is consumed in crushing operations, and it is still increasing year by year; Cutting, which has high dimensional requirements for the processed materials. [0003] In this regard, there is a gravity crushing mechanism in the prior art, such as Chinese patent document CN104368430A, which discloses an innovative process for multi-stage continuous automatic cr...

AI Technical Summary

Problems solved by technology

However, because there is no screening mechanism in this kind of crushing mechanism, the size of the discharged particles is different, and an independent screening device is required to re-screen in the later stage, which makes the crushing operation of materials cumbersome and the production efficiency is not high.
