Brief analysis of working principle and iron removal method of wollastonite iron removal equipment
Wollastonite iron removal equipment: Not only weakly magnetic minerals for coarse selection, the process can be used for non-magnetic minerals in addition to iron, the magnetic lines of high quality multi-neodymium-iron-boron magnetic materials, magnetic stability, a strong magnetic force, large capacity, and high recovery rate. The separated iron powder has a high grade and can be directly sold, which greatly improves the comprehensive utilization rate of wollastonite. Wet magnetic separator works: The slurry is fed into the magnetic separator tank through the feeding tank, and enters the mining area in a loose state. When passing through the magnetic field, the magnetic particles with strong magnetic properties are adsorbed on the surface of the cylinder under the action of the magnetic field. During the rotation of the cylinder, the magnetic ore particles are chained and flipped, and a part of the gangue is intercalated in the magnetic mineral. The ore and sediment are washed away by water, and the magnetic ore particles rotate with the cylinder, and are taken out of the minefield and washed into the mine by water. The non-magnetic minerals are thrown off, and under the action of the slurry flow in the tank, the tail The ore tank is discharged to complete the sorting process. Advantages of wollastonite iron removal equipment: 1. The magnetic system is made of high quality NdFeB, with high magnetic energy, strong tenacity and high magnetic flux density. 2. The multi-layer induction pure iron magnetic conductive material is used as the magnetic medium, and the magnetic field gradient is high. 3. The working surface has excellent magnetic field properties and is in direct contact with minerals. 4. The programmer control system is designed without manual operation. Wollastonite iron removal method: In order to achieve the purpose of removing iron-containing minerals, the magnetic force of the wollastonite iron removal device acting on the magnetic ore particles is greater than the combined force of all mechanical forces acting on the magnetic ore particles. The more the number of magnetic separations, the finer the wollastonite particle size, and the better the iron removal effect. For wollastonite containing heterogeneous weak magnetic impurity minerals, it can be selected by using a wet magnetic separator in a thousand orients. For magnetomagnetic minerals containing magnetite as the main impurity, weak magnetic properties are used. Or the middle magnetic separator is better.
The function of the Hydraulic Filter is to filter out various impurities in the hydraulic system. The main sources are mechanical impurities that remain in the hydraulic system after cleaning, such as rust, cast sand, welding slag, iron filings, paint and cotton yarn, etc., external impurities entering the hydraulic system, such as through the oil filler entrance and dust entering at the scraper seal; impurities generated during the working process, such as debris formed by the hydraulic action of the seal, metal powder generated by relative wear and movement, colloid, asphaltene, carbon residue, etc. due to oxidative deterioration of the oil.
