A kind of ore crushing device

Abstract

The present invention is applicable to the technical field of mining machinery, and provides an ore crushing device, comprising: a casing with a discharge opening at the bottom; a hopper connected to the top of the casing and used to contain ore to be crushed; a sieve plate fixedly installed Inside the shell, it is used to screen the broken ore and support the broken ore; the rotating shaft is set inside the shell; the crushing mill is placed on the sieve plate by rolling and connected to the rotating shaft for driving The ore moves and is rolled on the sieve plate; the breaking hammer is connected to the sieve plate in rotation, and the driving part is connected to the rotating shaft to drive the rotating shaft to rotate; wherein, the rotating shaft is fixedly connected with a screw pressing plate; the screw pressing The plate rotates with the rotating shaft and presses the connecting rod to lift the breaker, the crushing roller pushes the ore into the bottom of the breaker, and the breaker falls to break the ore. The invention has the advantages of simple structure, convenient operation, good mechanical linkage, energy saving and good synchronization.

Description

technical field [0001] The invention belongs to the technical field of mining machinery, in particular to an ore crushing device. Background technique [0002] People live in nature and need to continuously absorb living materials from nature to meet people's needs for life. Many materials are extracted from ores, forests, oil, etc., and the materials obtained from ores have a history of thousands of years. Ore refers to mineral aggregates from which useful components can be extracted or which have certain properties that can be utilized. Can be divided into metallic minerals, non-metallic minerals. The unit content of useful components (elements or minerals) in the ore is called the ore grade. The ore cannot be used directly from the mine. Multiple treatments are required before the ore is extracted. The first step is to crush it. Existing crushing equipment often uses The broken hammer is used for crushing, but the kinetic energy utilization rate of the broken hammer is ...
