A kind of ore crushing device with swing screening function

Abstract

The invention discloses an ore crushing device with a swing screening function, which comprises a base, support plates are fixedly arranged on the left and right sides of the top of the base, a crushing box is fixedly arranged between the tops of the left and right support plates through brackets, and a cutting box is connected to the bottom of the crushing box There is a screening box above the base, and the bottom of the screening box is connected to the base through a spring; a screen is arranged in the screening box; a cylindrical ring is fixedly connected to the center of the bottom of the screening box, and a first reduction motor is fixed on the top of the base. The motor shaft at the top of the motor is fixedly connected with a disk, the left side of the top of the disk is fixedly connected with a pin shaft, and the top of the pin shaft is fixedly equipped with a first bearing, the first bearing is located in the cylindrical ring and offsets against the inner wall of the cylindrical ring. The invention drives the circular movement of the pin shaft through the rotation of the disk, and the circular motion of the cylindrical ring is driven by the pin shaft through the first bearing, so that the screening box swings under the limitation of the spring, and the crushed ore shakes in the grinding barrel, and the screening effect is good.

Description

technical field [0001] The invention relates to the technical field of ore processing machinery, in particular to an ore crushing device with a swing screening function. Background technique [0002] Ore refers to mineral aggregates from which useful components can be extracted or which have certain properties that can be utilized. Ore crusher is one of the necessary equipment in the process of ore processing. For example, in the process of iron ore processing, large pieces of iron ore need to be crushed before subsequent smelting. [0003] Ordinary ore crushing devices lack the screening function, and the size of the crushed ore particles varies, which affects subsequent processing; although some ore crushing devices are equipped with screening devices for screening, the screening efficiency is not high, the screening effect is not good, and the screening is qualified. The ore and unqualified ore need to be separated manually, which is very inconvenient. Contents of the ...
