Arc Plate Electrostatic Separator

Product Overview
Arc Plate Electrostatic Sorting Machine is a kind of high-efficiency electrostatic sorting equipment, which adopts innovative multi-layer arc plate structure design, and is specially used for separating and selecting conductive and non-conductive minerals. The equipment realizes accurate mineral sorting through the action of high-voltage electrostatic field, which is especially suitable for the purification of complex minerals such as manganese ore, ilmenite, zircon sand, rutile, etc. The processing capacity is up to 1-2 tons/hour, and it is the key equipment for the processing of rare metals and strategic mineral resources.

Core Advantages

Sorting Performance

• Multi-layer sorting design: double-row 4-5 stage sorting structure, sorting efficiency increased by 30%.

• Wide particle size adaptation: 0.1-3mm materials can be effectively sorted.

• High purity output: the purity of conductor minerals can reach more than 90%.

Structural innovation

• Composite electrode system: stainless steel grounding arc plate + aluminum high-voltage electrostatic plate

• Adjustable electrode design: flexible adjustment of pole pitch and angle

• Modularized structure: easy maintenance and process adjustment

Working Principle

• Feeding preparation: the minerals are uniformly fed into the upper arc plate after pretreatment.

• Electric field sorting:

  • Conductor minerals: inductively charged → adsorption deflection → front discharge

  • Non-conductor minerals: maintain the original track → enter the lower layer to continue sorting

• Multi-stage sorting: after 4-5 layers of sorting to achieve complete separation

• Product collection:

  • Conductor products: the front part of each layer receives the ore hopper

  • Non-conductor products: collected at the end of the bottom layer

Comparison of technical parameters

Operation specification

Key control parameters

• Voltage adjustment: choose 30-60kV working voltage according to the mineral characteristics.

• Feeding speed: keep 10-15cm/s uniform feeding speed.

• Pole distance setting: usually adjusted in the range of 50-80mm

• Environment control: Humidity should be kept below 40%.

Safety Precautions

• Insulation fence must be installed in the high voltage area

• Discharge for more than 5 minutes after stopping the machine

• Regularly check the grounding resistance (≤4Ω)

Maintenance points

Arc Plate Electrostatic Sorting Machine provides a reliable solution for the separation and purification of complex minerals through its unique multi-stage sorting structure and precise electric field control. The equipment is particularly suitable for small and medium-sized high-value mineral selection operations, and its low energy consumption and high efficiency make it important in the field of comprehensive utilization of resources.
