Ore crushing device

Abstract

The invention is applicable to the technical field of mining machinery, and provides an ore crushing device. The ore crushing device comprises a shell, a hopper, a sieve plate, a rotating shaft, a crushing roller, a crushing hammer and a driving part, wherein a discharging port is formed in the bottom of the shell; the hopper communicates with the top of the shell and is used for containing to-be-crushed ore; the sieve plate is fixedly installed inside the shell and is used for screening the crushed ore and supporting the crushed ore; the rotating shaft is rotationally arranged inside the shell; the crushing roller is arranged on the sieve plate in a rolling mode, is rotationally connected to the rotating shaft and is used for pushing the ore to move on the sieve plate and rolling the ore; the crushing hammer is rotationally connected to the sieve plate; the driving part is connected with the rotating shaft and is used for driving the rotating shaft to rotate; a spiral pressing plate is fixedly connected to the rotating shaft; and the spiral pressing plate rotates along with the rotating shaft and presses a connecting rod to lift the crushing hammer, the crushing roller pushes the ore to enter the position below the crushing hammer, and the crushing hammer falls to crush the ore. The ore crushing device has the advantages of being simple in structure, convenient to operate, good in mechanical linkage, capable of saving energy and good in synchronism.

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. It can be divided into metallic minerals and 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 hamm...
