Silica Sand Ball Grinding Mill with +2000 Customers and High Reputation
For fine powder grinding, ball mill is also a kind of efficient equipment. As silica sand is very hard, ball mill is very suitable for grinding silica sand. Quartz sand is quartz particles made by crushing quartz stone. Quartzite is a non-metallic mineral. It is a hard, wear-resistant, and chemically stable silicate mineral. The color of the quartz sand is milky white or colorless translucent, with a Mohs hardness of 7. Quartz sand is an important industrial mineral raw material, non-chemical dangerous goods, and is widely used in glass, casting, ceramics and fire-resistant materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, filter media and other industries.
Quartz sand is made of natural quartz ore. The quartz stone mined from the mine is processed and then processed by crushing, screening, and washing. The appearance is polygonal, spherical, pure white, with high mechanical strength, strong ability to intercept dirt, and good acid resistance. Products with a fineness of less than 120Mesh are called quartz sand. Products over 120 Mesh are called quartz powder.
Working Principle of Silica Sand Ball Grinding Mill
The ball mill is composed of a horizontal cylinder, a hollow shaft for feeding and discharging, and a grinding head. The cylinder is a long cylinder. The cylinder contains a grinding body. The cylinder is made of steel. A steel liner is fixed to the cylinder. The grinding body Generally, it is made of steel balls, and is packed into the cylinder according to different diameters and a certain proportion. The grinding body can also be made of steel.
The material is selected according to the granularity of the grinding material. The material is loaded into the barrel by the hollow shaft at the feed end of the ball mill. When the barrel of the ball mill rotates, the grinding body is attached to the liner of the barrel due to inertia and centrifugal force and friction. It is taken away by the cylinder. When it is brought to a certain height, it is thrown away due to its own gravity. The falling grinding body crushes the material in the cylinder like a projectile.
The material is fed into the first silo of the mill by the feeding device through the hollow shaft of the feeding material. The silo has stepped lining or corrugated lining, which contains various specifications of steel balls. The centrifugal force generated by the rotation of the cylinder brings the steel balls to a certain level Falling after the height, it has a heavy impact and grinding effect on the material. After the material is coarsely ground in the first bin, it enters the second bin through a single-layer compartment board. This bin is inlaid with a flat liner and steel balls inside to further grind the material. The powder is discharged through the discharge grate plate to complete the grinding operation.
