CTNM Series Countercurrent
CTNM series permanent magnetic cylinder separators are cylinder magnetic separators with permanent magnetic system, which are suitable for wet separation of strong magnetic minerals with fine particles or removal of mixed strong magnetic minerals in non-magnetic minerals. The machine can continuously feed and discharge ore, with large magnetic field depth, large working gap and large processing capacity. It is a full counter current wet magnetic separator.
Adopted standard: machinery industry standard permanent magnet cylinder magnetic separator, standard number:JB/T 7895-2008，Permanent magnetic drum separator for coal, Standard No：JB/T 10998-2010
1. Type
(1) The magnetic system type of magnetic separator is divided into multi pole fan-shaped open magnetic system (generally 5, 7, 8, 10, 11, 12, 13 poles, also can be divided into main stage and sub stage).
(2) The type of tank is full counter current type. It is indicated by "n", i.e. CTN, or ctnm
(3) The full counter current tank magnetic separator is suitable for roughing and cleaning of ore with particle size of 0-6 mm, as well as heavy medium recovery in coal preparation industry.
2. Model
Examples of models are as follows:
3. Purpose
CTN or CTNM series magnetic separators are wet separators. It is suitable for heavy medium recovery in coal preparation industry.
4. Characteristics
According to the characteristics of raw ore in different regions, especially for the recovery of heavy medium iron powder in heavy medium coal preparation plant, we have improved the comprehensive collocation of magnetic system pole number, magnetic wrap angle, magnetic field intensity and magnetic field absorption depth on drum surface, and magnetic field gradient of multi-stage magnetic system, The new magnetic circuit design is adopted in the magnetic system, which not only improves the magnetic field strength, but also mainly improves the magnetic field depth absorption ability. At the same time, in order to improve the recovery rate of magnetic medium, the tank structure was reformed, so as to increase the length of the selected area and solve the problem of overflow. At the same time, the problems of wear resistance and handling capacity are solved, the handling capacity of single magnetic separator is increased, and the service life is prolonged. The magnetic roller bearing is changed into double seal, which solves the problem of water easily entering into the cylinder, and at the same time, it is easy to replace and maintain, thus prolonging the service life of the equipment. The structure of the drive system is simple and easy to maintain (chain drive). The wear-resistant layer on the surface of the stainless steel drum of the magnetic separator is generally stainless steel wear-resistant layer, and there are other forms. The service life of the wear-resistant layer is related to the particle size of the ore and the daily working time. Users can choose. Through the overall improvement of the full counter current magnetic separator, if the feed concentration of the full counter current magnetic separator can meet the following conditions: solid content When the content of magnetic substance is more than 13% and the content of non-magnetic substance is less than 12%, the recovery rate of magnetic medium can reach more than 99.9%.

CTS Series Co-Current CTS series co-current wet drum magnetic separator is designed for handling minerals with particle sizes from 0-6mm, it is specially used for pre-selection of coarse-grained ore, such as river sand, sea sand, etc. And it is also suitable for recovering of magnetic heavy media. |
CTB Series Semi-Countercurrent CTB series semi-countercurrent wet drum magnetic separator is designed for handling minerals with particle sizes from 0.6-6mm, it is widely used for the separation of ores after a grinding process, because of its high concentrate sorting ability and high metal recovery. |
CTN Series Countercurrent CTN series countercurrent wet drum magnetic separator is designed for handling minerals with particle sizes from 0-0.5mm, especially for mineral with particle size from 0-0.15mm, it is suitable for primary separation and scanning operation of fine-grained magnetic ore. The slurry will pass through a long separation zone, to achieve the best sorting effect and the highest metal recovery rate. |
