Electrostatic Separators

Dry Electric Separation and High Recovery Mineral

Our electrostatic separator uses the difference in electrical properties of various minerals and materials in nature to separate them. The sorting effect is good, and the grade of the obtained concentrate is high. JXSC mainly has two types of arc plate electric separators and stick electric separators. According to the customer’s requirements for material extraction components, purity, capacity, etc. We can customize a matching double-roller or four-roller electrostatic separator.

Brief Intro

The electrostatic separator can only sort dry materials with particle size less than 2mm. It is not suitable for the separation of large particle materials, so the materials must be crushed before separation. Mainly used for sorting conductive and non-conductive minerals, such as conductive minerals: magnetite, ilmenite, rutile, tin ore, etc. Non-conductive minerals: graphite, quartz, zircon sand, monazite, garnet, feldspar, calcite, tungsten ore and silicate minerals, etc. Heavy minerals in coastal areas can be sorted. It can also separate non-ferrous and non-metallic materials such as copper, tin, aluminum, and plastics from waste.

Electrostatic Separators Working Principle

When various minerals with different conductivity pass through an electric field, they have different charges due to electrostatic induction or the effect of capturing charged ions. After the conductor material is electrified, it is put into the ground through the grounding rotating roller, and with the inertia of the rotating roller, the conductor material is thrown into the conductor receiving hopper. After the non-conductor material receives electricity, due to its poor conductivity, it is adsorbed on the surface of the rotating roller, and as the roller turns to the back, it is swept by the brush and falls into the non-conductor receiving hopper.

Frequently Asked Questions

We need to know the following information:

(1) What minerals are sorted?

(2) What is the maximum feed size?

(3) How much capacity is required?

High voltage static electricity requires that the sorted material must be dry. Because the high voltage of tens of thousands of volts is used for sorting, the risk is relatively high.

(1) The machine is equipped with a chassis, which should be placed vertically during installation.

(2) Good grounding. The ground wire should be buried in a damp place 2-3 meters underground with angle iron or water pipes.

(3) High-voltage cables should be placed in plastic tubes to prevent leakage.

(4) The ore storage heating wire should be a 4.5 square millimeter cable. There are high and low temperature switches in the control cabinet.

(5) Due to the tens of thousands of volts of high voltage generated inside the equipment during operation, special attention should be paid to personal safety during operation.

According to different job requirements, the speed should also be different. When the conductor product is concentrate ore, the sweeping operation should use high speed to ensure the recovery rate of the conductor as much as possible. When selecting operations, in order to ensure the conductor grade, it is advisable to use low speed. Contact our professional engineers for details.
