Crusher Wikipedia. A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials as in rock ore, so that pieces of different composition can be differentiated.

Rocks and minerals play a valuable role in natural systems such as providing habitat like the cliffs at Grand Canyon National Park where endangered condors nest, or provide soil nutrients in Redwood where the tallest trees in the world grow. Rocks and minerals are important for learning about earth materials, structure, and systems.
The right materials are hard and competent rocks that generally fragment into cubical products. Igneous rocks, such as basalt and granite, are an excellent source of aggregate because they are hard, tough, and dense. Sedimentary rocks, such as limestone, are more challenging than igneous rocks to crush.
