Micronization in place of a ball mill or Raymond mill
Ultra Fine Raptor Mill is a licensed, innovative, and commercialized technique for particle size reduction to reduce, within seconds, solids that are capable of fracturing into a particle-sized powder. It replaces a conventional ball mill, impact mill, hammer mill, tower mill, etc. Ultrafine Raptor milling has created the potential to revolutionize the mineral processing industry due to the benefits attained through being able to economically mill finer and to enhance particle liberation for improved precious metals recovery.
An ultra-fine Raptor by means of tornado/vortex airstream. The Raptor is done by the mechanical effect of rotating impeller as well as intensive vortex airstreams and high frequency of air pressure oscillation generated at the backside of the rotating rotor and the groove slopes. Material is taken into the mill being carried by the airstream. The airstream containing material is given spiral motion in the inlet spiral chamber and transmitted evenly into the milling chamber.
Dry Separation by Electrostatic Discharges
An electrostatic separator is a device for separating particles by mass in a low energy charged beam. It works on the principle of corona discharge, where two plates are placed close together and high voltage is applied. This high voltage is used to separate the ionized particles. Electrostatic separation is a process that uses electrostatic charges to separate crushed particles of material. This process can help remove valuable material from ore. Generally, electrostatic charges are used to attract or repel differently charged material.
In electric mineral separation Quadrant Roller Electrical Sorter is considered one of the major equipment. Meanwhile, the disadvantage of the roller type is a limit for separating micron size as most precious metal forms in tiny micron size and low capacity of separation (1 ton per hour).
In separation of electric mineral Quadrant Roller Electric roller is considered
For this reason, we revolutionized the industry with a low costs electrostatic separators which are a combination of roller type and plate type superiors. Our plates are vertically positioned and 16 pairs of plates and four sets of the roller are in the system. Advantages of this system compared to competitors are compact size, low sales price, the ability to separate micron size, large production capacity, and using low power. Our plates attract positive conductive particles more effectively by using our patented graphene anodized aluminum plates and a combination of the roller and the plate.
