Crusher

A machine that reduces solid materials to smaller pieces by compression, impact, or grinding. Crushers are used to prepare materials for handling, processing, or disposal.

Jaw crusher: A crusher that breaks material between a fixed jaw and a moving jaw. Its reciprocating jaws reduce large, hard feed by compression.
Mining: The extraction of minerals and other geological materials from the Earth. Mines use staged crushing to prepare ore for separation and processing.
Comminution: The reduction of solid materials into smaller particles by crushing or grinding. Crushing is the coarse-size-reduction stage within this broader process.
Shredder: A machine that tears or cuts bulky material into smaller pieces using rotating cutters or shafts. Shredders often handle flexible or mixed waste that resists conventional crushing.
Energy consumption: The amount of energy used by a process, machine, or system. Crusher power demand can be substantial, especially with hard or oversized feed.
Gyratory crusher: A crusher with a gyrating conical surface that compresses material against a stationary outer shell. Its continuous compression suits large-scale primary crushing.
Quarry: An open excavation where stone, sand, or gravel is extracted. Quarries crush rock into aggregate for construction and other uses.
Compression: A force or loading that pushes material inward and tends to shorten or compact it. Compression fractures brittle feed between opposing crusher surfaces.
Grinding mill: A machine that reduces solids to fine particles by abrasion, impact, or compression. Mills generally take smaller feed and produce finer output than crushers.
Dust: Fine solid particles suspended in air or deposited on surfaces. Fracture and material handling release dust that requires control.
