Quartz can be found in sand deposits, high purity crystal deposits and is found to some degree as a minor component in most mineral formations. Quartz is highly abrasive with a Mohs hardness value of It is also very chemical resistant and durable. Ground quartz is used as fillers in the paint, adhesives and plastic industries.

Introduction: The ball mill is a tumbling mill that uses steel balls as grinding media. Ball mills can be used in wet or dry systems for bulk and continuous milling, and are most widely used in small or largescale ore beneficiation plant. Dry grinding: suitable for materials that react with water, such as building stones such as cement and marble.

Spherical grinding media are predominantly used in final stages of ore grinding. The spherical balls change shape through breakage and wear. Though this is universal in milling, its contribution and effect on milling kinetics, load behaviour and mill power is not fully established. One area that is usually ignored is the relationship between

The quartz ball mill uses a grooved ringshaped lining plate, which increases the contact surface of grinding balls and ore, strengthens the grinding effect, reduces energy consumption. 2. The tapered design at the discharge end not only increases the volume, but also forces the quartz material and steel balls at the cone end to be classified.
