Ore sand sorting machine capable of realizing multi-layer screening

Abstract

The invention discloses an ore sand sorting machine capable of realizing multi-layer screening. The ore sand sorting machine comprises a sorting mechanism, wherein the sorting mechanism comprises an initial separation mechanism and a re-separation mechanism; the re-separation mechanism comprises a separating filter screen a, a gathering plate, a central runner and a separating filter screen b; thegathering plate is fixedly connected to the bottom of the separating filter screen a; a gathering cavity a is enclosed between the outer wall of the separating filter screen a and the outer wall of the gathering plate; a filter hole a which communicates with the gathering cavity a is formed in the tapered surface of the separating filter screen a in the form of an array; the central runner is arranged on the bottom center of the gathering plate, and communicates with the gathering cavity a; a filter hole b for sorting ore sand raw materials is formed in the tapered surface of the separating filter screen b in the form of the array; an opening in the upper end of the separating filter screen b can receive the ore sand raw materials which flow out from the tapered surface of the separatingfilter screen a; the re-separation mechanism can receive ore sand raw materials which flow out from the bottom opening end of the separating filter screen b, and can sort the ore sand raw materials; and the upper-end opening of the separating filter screen b is equipped with a limiting baffle plate which is of a ring-shaped structure.

Description

[0001] This invention is a divisional application for an invention patent with the application date of September 22, 2017, the application number: 201710868489.8, and the invention name "multi-grade separation method for ore sand". technical field [0002] The invention relates to ore sand separation equipment. Background technique [0003] 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 particl...
