PTMS MAGNETIC SEPARATOR

what is magnetic separation in chemistry?

The permanent magnet separator is made of a high-coercivity, high-remanence special permanent magnet "NdFeB" and other materials to form a composite magnetic system. It has the advantages of maintenance-free, strong magnetic force, long service life, convenient installation, convenient use and reliable work. It is suitable for removing iron from non-magnetic materials on belt conveyor, oscillating conveyor, electromagnetic oscillating feeder and cutting chute. Excavation of 0.1 to 35 kg of ferromagnetic material, the internal permanent magnet magnetic system has a service life of more than ten years. When the permanent magnet adsorbs more ferromagnetic materials, it is manually removed by a non-magnetic scraper or worn with gloves, which is suitable for continuous operation and less iron.

The electromagnetic iron remover is an electromagnetic device for erasing scattered non-magnetic objects and is usually installed on the head or the middle of the belt conveyor. The strong magnetic force generated by the electric current will be thrown out by the unloading belt after the iron piece mixed in the material is sucked up, and the purpose of active eradication can be achieved, and the longitudinal deviation of the conveyor belt can be effectively avoided, and the normal operation such as the crusher and the grinder can be maintained. .

The details are as follows:

1, no excitation coil, energy saving.

2, no need for rectification control device, high reliability.

3, there is no temperature rise problem, there is no "cold state" or "hot state" of the magnetic field strength, the magnetic field is constant.

4. When the power is cut off, the iron parts sucked on the iron remover will not fall back to the transported material.

5. There is no insulation and pressure resistance. Equipped with an explosion-proof motor-driven scrap iron conveyor belt, it becomes an explosion-proof dust collector. However, the magnetic field strength of the permanent magnet separator will be attenuated, and attention should be paid to the implementation when selecting.

The permanent magnet iron remover is a common equipment in the normal operation, and his skillful operation is directly related to the company's benefits. Generally speaking, there are two kinds of working methods for permanent magnet separators: one is to select the on-site manual control mode, and the other is to take the long-distance active control mode of the central control room. Under normal operating conditions, the work of the permanent magnet separator is placed in an active control mode. Its work control method is:

1. Permanent magnet iron remover starts control: the permanent magnet iron remover starts to work with the belt conveyor, and the belt conveyor starts. The pair of normally open contacts on the joint relay in the high voltage control cabinet are connected, and the permanent magnet iron remover Get the work order to start running.

2, permanent magnet iron remover control: the belt machine of the permanent magnet separator is discontinued, the joint relay on the belt conveyor control cabinet is de-energized, the normally open contact is disconnected; the permanent magnet separator is set to delay the stop function, in the joint position After the relay loses power, the delay is 10min, and the permanent magnet separator stops working.
