Crushing plant successfully installed in Bolivia

Henan Deya Machinery Co., Ltd. exported a complete crushing plant in March, 2014 to Bolivia, and it was successfully installed in July. The crushing plant with processing capacity 200 tons per hour, includes vibrating feeder 4900×1100, jaw crusher 750×1060, impact crusher 1210 two sets and vibrating screen 1800×4800, equipment are connected by belt conveyors. The run test was successful, and won great praise from the client. Engineers for guide the installation came back on 9th, August, 2014.

Jaw Crusher and Gyratory Crusher

Within the crushing circuit, a primary crusher reduces material down to a size that can be conveyed and fed to the secondary crushing circuit. The two most common primary crushers used for coarse run-of-mine material are the jaw and gyratory crushers. These primary crushers break rock through compressive forces created by a hard moving surface forcing and squeezing the rocks towards a hard stationary surface.

A Jaw Crusher reduces large rocks by dropping them into a flat “V” shaped space created between a fixed surface and a movable surface. The compression is created by forcing the rock against the stationary plate. The opening at the bottom of the jaw plates is the crusher product size gap. The rocks remain in the jaws until it is small enough to pass through this adjustable gap at the bottom of the jaws.

In a gyratory crusher, a round moving crushing surface is located within a round hard shell which serves as the stationary surface. The crushing action is created by the closing the gap between the hard crushing surface attached to the spindle and the concave liners (fixed) mounted on the main frame of the crusher. The gap is opened and closed by an eccentric drive on the bottom of the spindle that causes the central vertical spindle to gyrate.

How Jaw Crusher Works

The distinctive feature of jaw crusher is the two plates which open and shut like animal jaws. The jaws are set at an acute angle to each other, and one jaw is pivoted so that it swings relative to the other fixed jaw. Material fed into the jaws is alternately nipped and released to fall further into the crushing chamber. Eventually it falls from the discharge aperture.jaw crusher

Jaw crusher can crush the materials from soft to very hard, the materials can be dry to slightly wet, but not sticky. Reduction ratio from 1/3 to 1/5; it is widely used in heavy mining, quarried materials, sand & gravel, recycling, etc.
