Ore pulverizing and screening device

Abstract

The invention discloses an ore pulverizing and screening device which comprises a base, wherein a front slide rail and a rear slide rail are fixedly arranged at the top of the base, each slide rail isin slide connection with a left slide block and a right slide block, a screen box is arranged above the slide blocks, and the top of each slide block is respectively connected with the bottom of thescreen box through a second spring; a screen stencil fixedly connected with the inner side wall of the screen box is arranged in the screen box; a speed reducing motor is fixedly arranged at the top of the base; a disk is fixedly mounted on a motor shaft at the top end of the speed reducing motor; a hinge pin is fixedly arranged at the left side of the top of the disk; the hinge pin is rotationally connected with a connecting rod; the left side wall of the screen box is also hinged to a push plate through a connecting seat; and the right end of the connecting rod is connected with the left endof the push plate through a first spring. The ore pulverizing and screening device disclosed by the invention has the advantages that the disk rotates to drive the hinge pin to make circumferential motion so as to drive the screen box to move left and right and incline to a certain degree, thereby driving ores to sway left and right in the screen box to obtain a good screening effect.

Description

technical field [0001] The invention relates to the technical field of ore processing machinery, in particular to an ore crushing and screening device. Background technique [0002] Ore refers to mineral aggregates from which useful components can be extracted or which have certain properties that can be utilized. The ore crushing device is one of the necessary equipment in the ore processing process. For example, in the process of iron ore processing, it is necessary to crush large pieces of iron ore before subsequent smelting. Ordinary ore crushing devices lack the screening function, and the sizes of crushed ore particles vary, which affects subsequent processing; although some ore crushing devices are equipped with screening devices for screening, the screening efficiency is not high, and it is very inconvenient to use. Contents of the invention [0003] The object of the present invention is to provide an ore crushing and screening device to solve the problems raised...
