Iron ore crushing device

Abstract

The invention relates to a crushing device, in particular to an iron ore crushing device. The iron ore crushing device comprises a crushing box, wherein a water jacket is arranged on the outer side ofthe crushing box, a bulge is arranged on the inner wall of the crushing box, a feeding hopper is fixed at the top of the crushing box, an outlet of the feeding hopper is in butt joint with a feedingchute, the feeding chute is fixed on the inner surface of the upper plate of the crushing box, a baffle is arranged in an inner cavity of the feeding chute, two grinding crushing wheels are symmetrically arranged in the crushing box, an outlet of the feeding chute is located in the middle of the two grinding wheels, a stirring device is arranged below the grinding wheels, the stirring device is rotationally connected to a rotating shaft, the rotating shaft is fixed in a groove in the inner wall of the crushing box, crushing teeth are arranged below the stirring device, a discharging hopper isconnected to the bottom of the crushing box, and a vibrator is arranged on one side of the discharging hopper. According to the iron ore crushing device, the retention time of the iron ores in the crushing device is long, the crushing effect is good, blockage is avoided in the discharging process, the crushing device is cooled in the using process, the abrasion speed of the parts is reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to a crushing device, in particular to an iron ore crushing device. Background technique [0002] In the process of ore mining, the iron ore initially mined has a large block, which is not conducive to the transfer or storage of the ore. Therefore, an ore crushing device is generally installed in the mine to crush the iron ore with a relatively large block first. into small pieces before transport or storage. [0003] The traditional ore crushing device has defects in design. The residence time of ore in the crushing device is very short, resulting in poor crushing effect. The crushing of relatively large iron ore is often not up to standard, difficult to meet the requirements, and needs to be crushed again. [0004] In addition, the crushing device generates a lot of heat during the working process, which makes the parts wear out quickly and the service life is short. The output of the crushing device is small pieces of iron or...

Problems solved by technology

[0003] The traditional ore crushing device has defects in the design. The residence time of the ore in the crushing device is very short, resulting in poor crushing effect. The crushing of relatively large iron ore is often not up to the standard, which is difficult to meet the requirements and needs to be crushed again.

[0004] In addition, the crushing device generates a lot of heat during the working process, which makes the parts wear out quickly and the service life is short

The output of the crushing device is small pieces of iron ore, which is prone to jamming at the output port, which affects production efficiency
