An Improved Surface Structure of Yunnan Tin Shaker Coarse Sand Shaker

Abstract

The invention discloses an improved coarse sand shaking table face of a yunxi type shaking table. The shaking table face comprises a coarse selecting area (1), a coarse re-selecting area (2), a first fine re-selecting area (3), a second fine re-selecting area (4), a third fine re-selecting area (5), a shallow trench area (6) and a fine selecting area (7), all of which are sequentially arranged from the end close to a bedside to a tailstock. A bottom slope of the shaking table face is composed of three varying slopes and three flat slopes from the coarse re-selecting area, wherein the coarse re-selecting area is a first climbing wedge-out area, the first fine re-selecting area is a flat slope area, the second fine re-selecting area is a second climbing wedge-out area, the third fine re-selecting area is a third climbing wedge-out shallow trench area, the shallow trench area and the fine selecting area are triangular plane areas, and the gradient of the coarse re-selecting area and the gradient of the second fine re-selecting area are equal to and larger than that of the third fine re-selecting area. According to the improved coarse sand shaking table face, the recycling rate of cassiterite with the size fraction being -74 microns, the handling capacity of a shaking table and the capability of eliminating iron pyrite and iron ore can be improved.

Description

technical field [0001] The invention belongs to the technical field of mine beneficiation equipment, and in particular relates to the bed surface structure of a Yunnan tin shaker. Background technique [0002] Yunxi type shaker is mainly composed of transmission mechanism, frame and shaker surface, which has the advantages of high enrichment ratio and final concentrate can be obtained in one sorting. Among them, the structure of the shaker surface has a great influence on the beneficiation effect. The surface of the existing Yunxi shaker coarse sand shaker consists of a rough selection area (flat slope area), a rough multiple selection area (the first climbing pinch-out area), a first fine multiple selection area (flat slope area), and a second fine multiple selection area. Constituent area (the second climbing pinch-out area), the third fine multiple-selection area (flat slope area), the fourth fine multiple-selection area (third climbing pinch-out area), and the selected ...
