Summary:Grinding in ball mill and Raymond mill 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.
Grinding in ball mill and Raymond mill 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, limestone, etc.
The quarry plant grinding mills for the treatment of minerals, ores and other bulk materials for the grinding process. A large number of these mills are used for grinding silica sand for producing aerated concrete or fibre cement. The mills are also used for treating iron and various other ores. These mills are also available in different designs. Smaller mill sizes can largely be delivered in a pre-assembled state, which in turn means a great saving in terms of time and installation costs.
The applications of ball mills 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.
The design of quarry plant crusher grinding ball mill 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 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.
