Big magnetic force is the key to the development of large magnetic separators

The magnetic force of magnetite ore in the magnetic field not only determines whether or not the magnetite or waste rock can be separated, but also affects the quality of the separation index. How to reasonably determine the large specific magnetic force required for the sorting of 350mm large ore is the key to the design and development of large magnetic separators. Because the position of the magnetic system in the drum is adjustable, even when operating at different belt speeds, the large ore can be placed in a large magnetic area, which is advantageous for sorting.

In addition to the CTDG type, there are ∮ 1250mm × 1400mm permanent magnet pulleys developed in the mid-1980s and recently developed GT1416 type permanent magnet pulleys. When the former conducts industrial tests on the Shirengou Iron Mine, it may abandon 13% -18% of waste rock, increase the ore grade by 2.5% -4%, and the operation recovery rate may be controlled at 94% - 96%. Mobile crushing Station to save the cost of grinding and improve the ability to select plants. The magnetic system of the latter device is a composite magnetic system consisting of NdFeB and ferrite magnetic materials.

PE series Jaw Crusher (Bulge Breaker) is widely used in mining, smelting, building materials, roads, railways, water conservancy and chemical industries, etc., crushing various materials with a compressive strength of no more than 320 MPa, and being crushing materials. The block size must not be greater than the value specified in the parameters of the technical parameter table. It has features such as large crushing ratio, uniform product particle size, simple structure, reliable performance, easy maintenance, and economical operation cost. PEX Series Jaw Crusher (Fine Break) This equipment is widely used for material crushing in mineral processing, building materials, quarry and chemical industries. Suitable for coarse or medium crushing, various ore, rock and other materials with a compressive strength limit (2000kg/cm2).
