Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, minerals, quartz, etc. The applications of quartz milling equipment are ubiquitous in mineral processing and mining industry, metallurgy, cement production, chemical industry, pharmaceutics and cosmetics, ceramics, different kinds of laboratory studies and tests. Besides particle size reduction, ball mills are also widely used for mixing, blending and dispersing, amorphisation of materials and mechanical alloying. Our high quality quartz milling equipment with low price will help customers make high profits.
Quartz milling equipment
Quartz ball milling equipment usually consists of a cylindrical vessel mounted on an appropriate basis at both ends which allows rotation of the vessel around the center axis. The mill is driven by a girth gear bolted to the shell of the vessel and a pinion shaft moved by a prime mover. The prime movers are usually synchronous motors equipped with an air clutch or gear transmission. After the mill is charged with the starting material and the grinding media, the milling process takes place during rotation as a result of the transfer of kinetic energy of the moving grinding media into the grinding product.
The design of a quartz ball milling equipment can vary significantly depending on the size, the equipment used to load the starting material, and the system for discharging the output product. The size of a mill is usually characterized by the ratio “length to diameter” and this ratio most frequently varies from 0.5 to 3.5. The starting material can be loaded either through a spout feeder or by means of a single or double helical scoop feeder. Several types of quartz ball mills are distinguished depending on the discharge system and these types are commonly known as overflow discharge mill, diaphragm or grate discharge mill and centre-periphery discharge mill. In industrial applications, the inner surface of the mill is lined with mill liners protecting the steel body of the mill and incorporating mill lifters which help to raise the content of the mill to greater heights before it drops and cascades down.
Several basic concepts are commonly used in modeling of the quartz grinding process. The starting material naturally consists of particles which differ significantly in size which makes it necessary to define different size classes. Standard sieves are used to determine quantitatively the size of the particles in each size class.
