Mining Machinery
As a further introduction of mining machinery, this article will lead you to a new machine which one is an important machine in crushing machine. Cynthia Bartlett addresses the importance of the matter here. Crusher is used to reduce large rocks into smaller rocks, gravel, or rock dust. It may reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or reduces the size of a solid mix of raw materials, so that pieces of different composition can be differentiated. It has advantages of big reduction ratio, reliable operation, high productivity, lower operational costs and easy repair. Get more background information with materials from Mike Gianoni. With the rapid advancement of mineral resources integration utilization technique, the 2012 national total ore mining is more than 50 million tons, and crusher, as one of the most important fashion in ore mining, has been widely used in resource exploitation and mine construction. The jaw crusher is widely used in mining, building materials, chemical industry and metallurgy and so on.
The jaw crusher is suitable for primary and secondary crushing all kinds of minerals and rocks with compressive strength less than 320 MPa. Working principle of jaw crusher: The strip and Strip pulley are driven by a motor, and the movable jaw moves up and down via eccentric shaft. The angle between fixed jaw and movable jaw becomes smaller when the movable jaw runs down, then the materials are crushed into pieces. It will become bigger when the movable jaw runs up. The movable jaw board leaves the fixed jaw board under the action of pole spring, then the end products and come out from the crushing cavity.
