Mineral product screening screen body for screening block minerals by size

Abstract

The invention discloses a mineral product screening screen body for screening block minerals by size. The mineral product screening screen body structurally comprises a first-layer vibrating screen, a second-layer vibrating screen, a third-layer vibrating screen, a fourth-layer vibrating screen, slide rails, an outer barrel, a central main shaft, an electric motor, a crankshaft and rollers, wherein the electric motor is connected with the crankshaft; the crankshaft is connected with the central main shaft by a connecting shaft; and when the electric motor drives the crankshaft to rotate, the crankshaft drives the central main shaft to move up and down. The first-layer vibrating screen, the second-layer vibrating screen, the third-layer vibrating screen and the fourth-layer vibrating screen are mounted on the central main shaft from top to bottom in sequence; hollow holes on the four layers of vibrating screens are sequentially reduced in size, and rollers are mounted at the two sides of each layer of the vibrating screen; slide rails are arranged at the left side and the right side of the inner wall of the outer barrel respectively; and the rollers are mounted in the slide rails. According to the mineral product screening screen body, the design with multiple layers of vibrating screens is adopted, and the hollow holes on the four layers of vibrating screens are sequentially reduced in size, so that in a mineral screening process, minerals different in size on the layers are distinguished. The mineral product screening screen body is simple in structure, low in cost and relatively great in popularization value.

Description

technical field [0001] The invention relates to a mineral processing machine, in particular to a mineral screening sieve body for screening mineral lumps. Background technique [0002] Mineral screening is to separate sand, dust and other impurities in minerals through a filter screen. The traditional screening method is to manually shake the filter sieve for screening, which has low efficiency and high labor intensity. The structure of the existing vibrating screening machine is relatively complicated, and each vibrating screen needs to be equipped with a vibrating mechanism, and the manufacturing cost is relatively high. Therefore, there is a need for a mineral screening machine, which not only has high screening efficiency and high screening accuracy, but also has the characteristics of simple structure and low manufacturing cost. Contents of the invention [0003] Aiming at the deficiencies of existing mineral screening equipment, the present invention proposes a...
