Pin-type nanometer bead mills usually make the amazing performance in the field of Titanium Dioxide, zirconium silicate, ceramic ink, battery materials, inkjet ink, printing ink and other materials requiring Nano-scale fineness. Equipped with hollow axel agitator, and separator with super large mesh screen, large flow capacity is available. Under the grinding medias of mini size, materials can reach the fineness as required to Nano-scale. Characteristics: 1. High-duty pin type grinding system enable large circulation volume to be available; 2. Super narrow fineness distribution enable products to be very fine and at Nano-scale. 3. Super max filter separator to guarantee the large flow capacity; 4. Efficient well-designed cooling system, axes can be chosen to be cooled. 5. Materials like metal pin, ceramic, or high wear resistance PU are available; 6. With advantage of super max flux circulation grinding; heating generated from grinding discharges quickly, thus solve the problem of heat dispassion;
