This plant is widely used in dry way powder process of metallic and nonmetallic minerals, and powder size can be adjusted between 30 mesh and 2000 mesh. The processed ores include limestone, calcite, marble, kaolin, gypsum, barite, coal ash, slag, silicon carbide, brown alumina, cement, quartz, feldspar, refractory, etc.

Working principle
Raw materials are elevated by Bucket Elevator to Ball Mill for being ground. Materials ground by Ball Mill are sent to Classifier for being separated, so the coarse powder and fine powder are separated. Fine powder with suitable size is collected by cyclone collector, coarse powder is discharged from bottom part of Classifier and sent back by Returning Spiral to Ball Mill for being re-ground, this is a closed cycle, the air is discharged by Blower after being cleaned by Pulse Dust Collector.

Features
1. The plant is stable and highly automatic;
2. Inner lining and grinding media can be changed according to customers’ request, such as high manganese steel, silica, ceramics, etc.
3. Fine powder size is even and can be adjusted;
4. The system is low trouble rate, and can be operated continuously.
