Electrostatic separator Description High-voltage electricostatic separator is one of the main equipments for electric separation.It adops the different electrical property of all minerals and materials in the nature to realize the separation.The common minerals like ilmenite,magnetite,cassiterite,and monazite etc,have good conductivity property while quartz,zircon,feldspar,calcite,scheelite,and silicate minerals have poor conductivity property,then the electric separator adopts their different electrical property to realize the separation. Combined with permanent magnetic separator in the process flow of separating titanium-zirconium minerals,better effect can be achieved.The struture of the machine is made up of feeding device(including hoisting machine and heating chamber),ground roller,arc-shaped corona electrode,deflecting electrode,ore-transmitting board,high-voltage current,and electric control cabinet.The machine has reasonable structure,advanced technique,convenient electric operation,perfect protection,and high automation;moreover,it is safe,reliable,attractive and novel.Because of its good effect,the product also export to many distant market area such as Australia,Indonesia,South Africa,Vietnam and other foreign market and obtain good reputation.
High voltage electric separator (also known as electrostatic separator) is a device that utilizes the difference in material conductivity to separate materials through electrical and mechanical forces in a composite electric field combining high voltage corona electric field and high voltage electrostatic field. Its working principle is based on the effects of electric and magnetic fields, and it achieves the sorting of different particles by changing the charge state and motion trajectory of particles.
The high-voltage electric separator mainly consists of a feeding device, a high-voltage generator, a sorting room, and a dust collection device. The particles enter the sorting room through the feeding device, forming a charged particle cloud. The high-voltage generator generates a high voltage, which is applied to the sorting chamber through electrodes to form a strong electric field. Under the action of a strong electric field, particles in a charged particle cloud are subjected to electric field forces of different sizes and directions, resulting in different motion trajectories. Due to the different physical properties such as size, shape, and density of particles, they are subjected to different electric field forces, resulting in differences in their motion trajectories. Based on the motion trajectory of particles, it is possible to achieve particle sorting.
In addition, the high-voltage electric separator can further separate particles with magnetism through the action of a magnetic field. By adding a magnetic field to the sorting room, magnetic particles can be subjected to magnetic force, changing their motion trajectory, and thus achieving the sorting of magnetic particles.
The high-voltage electric separator is mainly used for the separation of conductive minerals and non-conductive minerals, and can also replace screening operations for the classification of the same material and the sorting work in some seed selection work. Its price varies depending on factors such as brand, specifications, and performance, and needs to be selected according to specific needs.

Working principle: The Electrical sorting method used the differences of conductive of different mineral, Under the influence of electric field, mineral particles are subject to electrical and mechanical forces(centrifugal force, gravity, drag) role, then they produce different tracks that make them to be separated, so we can achieve the purpose of sorting. When the temperature heated to 40°C-60°C after entered into the bin. the mineral particles enter into the power corona areas with the rotation roller shafts along the rotating feed roller(Grounding Electrode)surface, Corona current makes all the mineral particles(conductors and non-conductors) obtain negative charge, Because of low contact resistance. with the rotating feed roller, the conductor's charges transfer by the roller away quickly, Under the action of mechanical forces, conductors escape away from the roller, and enter into the mineral hopper(conductors), At the same time, because of higher contact resistance with the rotating feed roller, the non-conductors'charges couldn't transfer by the roller away as quickly as conductors', so they are forced in the roller surface owing to the role of electrostatic force, with the rotating feed roller, the non-conductors enter into the back of the roller, and are unloaded under brush, Then they are collected in the excellent hopper(non-conductors), At last the Semiconductor mineral particles or failed to fully discharge the conductor mineral particles enter into the middle hopper(semiconductor mineral particles).
