Working Principle of QF Grinding System:

This system comprises crushing, grinding, grading, packaging, silos, conveying, and elevators. After coarse crushing, the material is conveyed into the raw material silo and then fed into the ultrafine ball mill via a controllable feeder. Inside the mill, the grinding media utilize the energy gained from the mill's rotation to impact and grind the material. The pulverized material then enters an air classifier via a discharge silo to separate coarse and fine powders. Qualified fine powder is collected by a collector, while coarse particles are re-entered into the ball mill for further grinding via the classifier's discharge valve. Microparticles are filtered by a high-efficiency dust collector, and the purified gas is discharged by an induced draft fan.

Application Fields of QF Grinding System:

Calcite, marble, limestone, kaolin, gypsum, barite, fly ash, slag, silicon carbide, brown corundum, ultrafine cement, zircon sand, andalusite, mullite, refractory materials, quartz, feldspar, α-alumina, glass microspheres, fluorescent powder, zinc powder, aluminum powder, iron powder, molybdenum powder, etc.

Performance Advantages and Characteristics of QF Grinding System:
