Weak magnetic separating equipment has got rapid development in the last 20 years. An important develop trend of permanent type weak magnetic separator is large scale. The cylinder diameter has developed from 600mm, 750mm to 1050mm, 1200mm, 1500mm. the length has increased from 2100mm, 2400mm to 3000mm, 4000mm. multi-cylinder in tandem has significantly improve the processing capacity. However, the most widely used equipment is still the e1050 type permanent magnetic separator.
In 1965, we has designed and manufactured wet type permanent magnet separator using strontium ferrite as material, and got success in the Bengang Nanfen ore beneficiation plant. It got to spread and application soon, and realized weak magnetic separator permanent magnetization and serialization. At the same time, electro magnetic separator and 128-c3 belt type weak magnetic separator introduced from the original Soviet Union had gradually become obsolete. The permanent magnetic weak magnet separator played a dominant role.
Magnetic roasting can be divided into reduction roasting, neutral roasting and oxidizing roasting according to the principle. Studies have shown that the particle size has significant effect on the magnetic properties. The magnetic susceptibility decreases with the particle size. However, the coercivity value increases with decreases of particle size. This is especially apparent when the particle size less than 20-30 microns.
The ore beneficiation process is usually composed of by the magnetic separator and other mineral processing equipment. The quality of the products and accuracy of the magnetic separator is an important indicator to measure the magnetic separation. It is also the important indicator to measure the production of the entire beneficiation process.
We also actively used the new high and permanent magnet material (NdFeB) to increase the number of poles. The additional poles and compound magnetic field further enhanced the performance of permanent magnetic separator, matured and expended the ranges of applications, especially in the process of magnetite beneficiation.
With the in-depth development of the research work of the domestic and foreign high-performance permanent magnet materials, the industrialization of the magnetic separator and the constant optimization the upgrading and improvement of the magnetic system and the body structure of traditional permanent magnetic separator speed up the process that the permanent magnetic separation equipment gradually replace the electromagnetic magnetic separator. With the application of the automatic control and monitoring technology in the mining enterprises at home and abroad, the level of automation of mining equipment manufacturing is also correspondingly increased, which also brings increasingly high accuracy requirements in the magnetic field of mineral sorting.
Henan Hongxing Mining Machinery Co., Ltd is a large-sized hydro cone crusher, grinding mills manufacturer, and the mining equipment we researched and developed with great concentration plays an active role in the mining and ore beneficiation industry and is one of the indispensable mining crushing equipment in the mining industry. - https://www.affordablecebu.com/
