A spiral concentrator, a spiral concentrator method and an ore separating plate thereof

Abstract

The invention discloses a mineral separating plate. The mineral separating plate is characterized by comprising a fixed inner sleeve and a detachable outer sleeve, and the opposite radial positions of the inner sleeve and the outer sleeve are connected adjustably; preferably, the inner sleeve of the mineral separating plate is fixed to or welded to the screw concentrator or a screw chute intermediate shaft or a steel channel of the intermediate shaft through a bolt by the a bolt device; the side surface of an inner sleeve body and the side surface of an outer sleeve body are in consistent curve shapes; the inner sleeve and the outer sleeve are connected through an adjustable bolt device; a long adjusting groove used for fastening the adjustable bolt device is formed in the position, with at least 2 / 3 of the thickness of the inner sleeve body, of the inner sleeve body; a bolt hole used for fixing is formed in the fixing end of the inner sleeve; the outer sleeve body is in an inverted U shape buckled on the inner sleeve body; and a gasket used for eliminating a gap is arranged between the outer side face of the inner sleeve and the inner side face of the outer sleeve. When the quality of minerals changes, the length of the mineral separating plate can be conveniently adjusted, and therefore the number of light minerals and the number of heavy minerals can be reasonably separated.

Description

technical field [0001] The invention relates to a spiral concentrator, a spiral concentrator method and an ore separation plate thereof, in particular to a spiral concentrator whose length can be adjusted. It is a convenient and practical ore-separating adjustment device for separating heavy minerals and light minerals. Background technique [0002] In the prior art, a spiral concentrator or a spiral chute is a device for sorting minerals based on the gravity separation principle. Especially in non-ferrous metal beneficiation, non-powered mineral separation equipment is widely used. The ore pulp swirls down from the top. separation. [0003] Usually, the ore separation plate is used to block the heavy minerals inside, so that they flow into the heavy mineral collection process pipeline, while the light minerals bypass the ore separation plate and flow into the light mineral process pipeline, so as to achieve the purpose of diverting minerals with different specific gravity...

AI Technical Summary

Problems solved by technology

However, in this technical field, a kind of technical prejudice has been formed, thinking that the length of the mining board should be designed according to traditional principles, and no one realizes that this is an innovative point, and no one realizes that it should be changed to With a variable-length structure, it is even more impossible for those skilled in the art to consider how to change the length of the ore-distributing plate

[0006] Under the influence of this technical bias, the length of the ore separation plate is always fixed, resulting in that when there are many heavy minerals, the heavy minerals cannot be effectively blocked and shunted out, and the heavy minerals are mixed into the light minerals; when there are many light minerals, it will cause Divide too much light minerals into heavy minerals, affecting the separation effect of ore dressing
