An energy-saving coal mine magnetic separator and its screening method

Abstract

The invention discloses an energy-saving coal mine magnetic separator and a screening method thereof. It comprises an outer casing, a screening space is arranged in the outer casing, and a screening mechanism is arranged in the screening space. The invention can screen the coal mines with iron raw materials, through the evenly distributed and simultaneous rotating screening rods, the coal mines that are too small in size can be effectively separated, and after being crushed, they can be collected together as coal mine powder, which is convenient for subsequent use, and the coal mines with qualified sizes can be collected together. The coal mines with a large size and the coal mines with an oversized size are separated by a baffle plate, and the coal mines with a qualified size and the coal mines with an oversized size are discharged from different positions through the drive of multiple friction wheels. The separation is very simple and fast. There are two kinds of The magnetic separation method adopts the form of electromagnetic drum for powdery iron raw materials, which is very uniform. For block iron raw materials, it is adsorbed by relatively powerful electromagnetic plates. The electromagnetic plates work intermittently, which is very energy-saving as a whole.

Description

technical field [0001] The invention relates to the related technical field of a magnetic separator for mineral processing, in particular to an energy-saving coal mine magnetic separator and a screening method thereof. Background technique [0002] Magnetic separator is a kind of mechanical equipment that uses magnetism to separate iron raw materials from minerals. It is widely used. In the mining of coal mines, there are usually iron raw materials that need to be removed. In the screening of coal mines, it is necessary to , the size of the coal mine is screened for various purposes, and in the existing equipment, the form of magnetic separation is often relatively simple, regardless of the magnetic size of the raw material, uniform adsorption is carried out, which is a waste of energy and low in efficiency. In the size of the coal mine Screening is usually carried out by means of a perforated plate combined with shaking, which is very inefficient and not suitable for large-...
