Abstract

The invention belongs to the technical field of mineral processing equipment, particularly relates to a screening device for mineral processing. The device aims to solve the problems in the prior art. The screening device comprises an outer shell, a round hole is formed in the outer wall of the top of the outer shell, a feeding hopper is arranged above the round hole, the outer wall of the bottom of the feeding hopper is fixedly connected to the outer wall of the top of the outer shell through a supporting column, a first sieve tray, a second sieve tray and a third sieve tray which are distributed up and down are arranged in the position, the interior below the round hole, of the outer shell, and flanges are arranged on the side edges of the first sieve tray, the second sieve tray and the third sieve tray. According to the screening device, the stroke during ore screening can be increased, then ore screening can be more sufficient, the ore screening effect is improved, ore on the first sieve tray, the second sieve tray and the third sieve tray can be shaken, the ore screening effect is improved, ore moving on the first sieve tray, the second sieve tray and the third sieve tray can be more dispersed, and the ore screening efficiency is improved. and therefore, ore screening can be more sufficient.

Description

technical field [0001] The invention relates to the technical field of mineral processing equipment, in particular to a screening device for mineral selection. Background technique [0002] Due to the massive development and utilization of mineral resources, subsequent processing such as smelting has increasingly high requirements on the quality of beneficiation products. In order to distinguish and utilize ores of different sizes, it is necessary to screen the crushed ores. [0003] Existing screening machines used in mineral processing have many structural types, such as fixed grid screens, curved screens, cyclone screens, roller screens, roller screens, shaking screens, inertial vibrating screens and resonance screens. At present, Inertial vibrating screens are widely used due to their simple structure, large production capacity, and high screening efficiency. Insufficient points. Contents of the invention [0004] Based on the technical problems existing in the prior...
