Multi-grade separation ore sand screening equipment for building materials

Abstract

The invention discloses multi-grade separation ore sand screening equipment for building materials. The equipment comprises a support mounted on the ground, a first shell arranged on the support, a material guide plate arranged on a first housing and a screening device arranged in the first shell. The screening device comprises a second shell arranged in the first shell, multiple connecting blocksconnected to the first shell and the second shell, a feeding opening arranged below the second shell, a stepped screening structure arranged in the second shell, a transmission structure used for enabling the stepped screening structure to cyclically move and a discharging structure arranged below the stepped screening structure. Through the arrangement of the stepped screening structure, the occupied area of the ore sand screening equipment is effectively reduced, the sand stone screening duration is prolonged, the screening effect is enhanced, finally-obtained screening products are more standard, and the percent of pass is higher.

Description

technical field [0001] The invention belongs to the technical field of ore sand separation, in particular to a kind of ore sand screening equipment for multi-grade separation of building materials. Background technique [0002] The screening machine is a vibrating screening mechanical equipment that uses the relative movement between the bulk material and the screen surface to make some particles pass through the screen holes, and divide sand, gravel, crushed stone and other materials into different grades according to the particle size. The screening machine for mining includes a frame, a screen set on the frame, and a driving mechanism that drives the screen for vibratory screening. The screen surface of the screen is arranged obliquely, and the materials to be screened are introduced from the higher end of the screen. The screened materials of various particle sizes are discharged from the lower end of the screening machine. [0003] translate [0004] The existing ore ...

AI Technical Summary

Problems solved by technology

[0004] The existing ore sorting machine is usually limited by the structure, which leads to a large overall size of the screening machine, which leads to the need to occupy a large area in the mining area and is inconvenient to carry. When there is a lot of ore, a part of the sand and gravel is often driven by the crushed stone, resulting in a much lower output of sand and gravel than the expected value, and affecting the pass rate of the final crushed stone
