Automatic feeding type multi-stage ore crushing device

Abstract

The invention discloses an automatic feeding type multi-stage ore crushing device. The device comprises a base, a crushing shell, a breaking shell, electric breaking rollers, electric grinding rollersand a discharging assembly, wherein first supporting legs are fixedly arranged at the four corners of the bottom end of the crushing shell respectively, and the first supporting legs are fixedly arranged at the top end of the base; the breaking shell is fixedly arranged at the top end of the crushing shell; the electric breaking rollers are arranged in an inner cavity of the breaking shell; the electric grinding rollers are arranged in an inner cavity of the crushing shell; and the discharging assembly is arranged at the top end of the base. According to the automatic feeding type multi-stageore crushing device, by controlling the feeding amount of ore, ore stacking in the crushing shell due to high breaking speed of the ore in the breaking shell can be avoided, normal operation of the device is guaranteed, secondary transferring of the ore is reduced, therefore the occupied area of the device is effectively reduced, the production cost is greatly reduced, and the device is very suitable for small and medium-sized ore extraction enterprises.

Description

technical field [0001] The invention relates to the technical field of ore crushing, in particular to an automatic feeding type multi-stage ore crushing device. Background technique [0002] The primary purpose of ore crushing is to dissociate minerals. Crusher generally processes larger pieces of material, and the product particle size is relatively coarse, usually greater than 8mm. It is divided into coarse crusher, medium crusher and fine crusher. Generally speaking, the materials processed by the grinding machine are relatively fine, and the product particle size is fine, up to 0.074 mm, or even finer. Its structural characteristics are broken parts ( or medium) in contact with each other, the medium used is steel balls, steel rods, gravel or ore blocks, etc., but some machines have both crushing and grinding functions at the same time, such as self-grinding machines, ∮5.5×1.8 meters self-grinding The upper limit of machine-processed ore particle size can reach 350-400m...
