Crushers, grinding mills and pulverizers are types of grinding equipment used to transform or reduce a coarse material such as stone, coal, or slag into a smaller, finer material. Grinding equipment can be classified into to two basic types, crushers and grinders. Industrial crushers are the first level of size reducer; further granularization ...

The largest primary gyratory crushers cost US $2 million or more, while overall crushing plant costs can be as high as $18 million. It's necessary therefore to estimate crusher installation costs based on equipment costs plus the following direct costs, including construction contractor indirects: • Earthworks • Mechanical • oncrete

A crusher is a machine that reduces large rocks into smaller rocks, gravel, or rock dust. Crushers are mainly used in the mining and construction industries, where they are used to break down very large rocks and boulders into smaller pieces. Crushers are also commonly used for jobs like breaking up asphalt for roadwork or demolition projects.

The coarser stages are termed "crushing" while the finer ones are termed "grinding", largely as a result of the nature of the processes involved at each stage. Usually between 1 and 4 stages of crushing is used. Crushing is usually more energy efficient, but this becomes less clear for very fine crushing in tertiary or later stages.

Quarrying is used mainly in the production of construction and building materials, such as solid stone or crushed rock for aggregates, or for raw materials for processes such as cement manufacture. As a technique, quarrying is normally only used where raw materials of adequate quality and size cannot be obtained economically by other means.
