Electrostatic Separator

Electrostatic separator, also known as electrostatic separation equipment, high-voltage electrostatic separation machine, and electric separator. It is a key equipment widely used in resource recycling and material separation industries.It can separate conductive materials from non-conductive materials through high-voltage static electricity, and is capable of separating metals from non-metals in circuit boards. This high-voltage electrostatic separator is highly efficient in metal-nonmetal separation for various recycling scenarios.It is applicable for metal separation from waste circuit boards, waste wires and cables, various medicine blister packs, aluminum-plastic boards, food packaging bags, aluminum-plastic pipes, aluminum foil, etc. It is an important component of circuit board recycling equipment and copper granulator equipment. This electrostatic separation machine plays a crucial role in enhancing the performance of circuit board recycling lines and copper granulation systems.Additionally, this equipment can separate 2-5 different types of mixed plastics. Some models of this electrostatic separator can realize two rounds of sorting and extraction of materials in a single machine, effectively improving the purity of metals or plastics. The multi-round sorting function of this high-voltage electrostatic separation equipment ensures higher material purity for subsequent processing.

Working Principle:

It utilizes the differences in friction properties, heteroelectric properties, and dielectric series of materials. In a strong high-voltage electric field with an adjustable narrow gap of up to 70KV and a voltage difference of approximately 1.5MV/m, different objects are induced to carry different amounts of electric charge. Then, the mixed materials are sorted based on the differences in effective forces such as electrostatic discharge behavior, material gravity, and projectile motion speed. This working principle of the electrostatic separator ensures precise and efficient separation of various materials.The high-voltage generating device inside the equipment produces high-voltage static electricity and discharges to the grounded rotating roller. Materials are evenly fed onto the rotating roller through a dedicated feeding device. The stable high-voltage output of the electrostatic separation machine and the efficient feeding system contribute to consistent sorting results.Conductive materials, after being charged, discharge through the grounded rotating roller and are thrown into the conductive material hopper due to inertia. Non-conductive materials, due to their poor conductivity, are adsorbed on the surface of the roller and swept down into the non-conductive material hopper by a brush. Some conductive and non-conductive materials fall into the middle material hopper due to various factors and re-enter the feeding device for re-sorting. This cyclic sorting process of the high-voltage electrostatic separator ensures maximum separation efficiency and material utilization.

Application Scope:

It is mainly applied in industries such as resource recycling parks, waste home appliance disassembly, and waste plastic recycling. This electrostatic separator is a core equipment in the waste recycling industry, meeting the material separation needs of various recycling scenarios.It can separate metal and non-metal mixed particles, conductors and non-conductors; it is used for aluminum-plastic waste, copper-plastic waste, waste circuit board recycling equipment, and copper granulator matching; it can also be used for mineral sorting, carbon-containing material extraction, and metal particle and powder extraction from grinding wheel ash. This high-voltage electrostatic separation machine provides versatile solutions for material separation in multiple industries, including waste recycling and mineral processing.

Maintenance:

• Regular Dust Cleaning: A large amount of dust will accumulate inside the equipment after running for a period of time, which affects the sorting effect. It is necessary to regularly use the dust removal or dust blowing device equipped with the equipment to clean the dust and maintain the good sorting performance of the equipment. Regular dust cleaning of the electrostatic separator is essential to ensure its long-term efficient operation.
• Checking the Automatic Discharge Function: Due to the high voltage inside the equipment, the automatic discharge function is crucial. Regularly check whether this function is normal to ensure the safety of operators. Regular inspection of the automatic discharge function of the high-voltage electrostatic separation machine is a key measure to ensure on-site operational safety.
• Monitoring Voltage Stability: Pay attention to the working status of the automatic voltage regulation device, especially during humid weather or peak power consumption periods, to ensure the stability of the high-voltage power supply and the sorting quality. Monitoring the voltage stability of the electrostatic separator helps maintain consistent sorting results in different working environments.
• Maintenance of Motors and Frequency Conversion Equipment: National standard motors and frequency conversion control equipment are the keys to the normal operation of the equipment. Regularly check their operating conditions, and repair or replace them in a timely manner if there is any abnormality. Proper maintenance of motors and frequency conversion components of the electrostatic separation equipment extends its service life and reduces unexpected downtime.
