Nowadays, people like to enjoy a high standard life and also to demand for quality building materials. Requirements of quality architectural ceramics and sanitary ware have become more sophisticated. Requirements of industrial equipment for Non-metallic mineral processing and refining are also becoming increasingly diverse. The equipment commonly used for removal of iron from non-metallic minerals is SLon vertical ring and pulsating high gradient magnetic separator (SLon VPHGMS), where wet high intensity magnetic separation method is applied. Wet high intensity magnetic separation has the advantages of easy sorting, but it also needs, when dealing with non-magnetic products, processes such as concentration, dehydration and drying to get final products. The existence of those processes has greatly increased investment and management costs. In addition, it requires extensive use of water. A lot of prospective tenements are located in remote areas but rich in non-metallic mineral resources. However, limited financial resources or lack of water resources in the remote areas greatly affect development and utilization of non-metallic mineral resources. Therefore the development of a dry beneficiation machine with high field strength is conducive to a large number of medium and small companies who are involved in non-metallic minerals and to those areas in which water is difficult to ontain. Our dry vibration high gradient magnetic separator will promote successfully further development of non-metallic mineral resources. Furthermore, land use can be significantly reduced and the environment is better protected.

Structure and Operation Principle

Wet magnetic separator is usually utilizing water as the medium where minerals are dissolved in water, to form slurry and then enter into the sorting areas. Magnetic material is attracted onto the magnetic media while non-magnetic material goes with the water through the magnetic medium into the non-magnetic ore bucket. The magnetic material is separated from the magnetic field by high-pressure water and is discharged into the concentrate bucket. The separation process is then completed. In order to achieve dry magnetic separation, the first problem to be solved is to make dry ores flowing. To solve this problem, a new idea of vibration ore-feeding, continuous vibration sorting and vibration discharging of magnetic material is adapted with this machine. SLon dry vibrating high gradient magnetic separator consists mainly of rotating rings, magnet yokes, excitation coils, racks, a vibration motor for rings, a vibration motor for ore bucket, a vibration mechanism, tire couplings, a limitation mechnism and other components.

When dry ore is fed into the system, it goes from the slot section of the upper part of magnet york into the sorting areas under the action of the vibration motor for ore bucket. Rings supported on the main vibration springs of the vibration mechanism transmit torques via the tire couplings. The rings under the action of the vibration motor are vibrating while continuous rotation. A magnetic medium box is built inside each ring , magnetic mineral is attracted onto the magnetic media box while non-magnetic mineral goes through the magnetic media box under the effect of vibration force of the ring into the non-magnetic ore bucket, and thus separated from the machine. With the ring's rotating, magnetic meineral is separated from the magnetic field, at the same time it is separated from the ring under the action of vibration force and collected into the magnetic ore bucket. As the magnetic ore bucket also vibrates along with the ring's vibration, it results in the magnetic ore being separated from the machine.
