Mobile jaw crusher plant sets crushing, screening, conveying and other equipment as one, can complete the crushing operation of all kinds of mine materials at a time. In addition, it also has a strong mobility, can go deep into the crushing site, complete the crushing operation of materials on the site. Because of the features of saving time and effort, mobile jaw crusher plant has a relatively wide range of application.

The main components of mobile jaw crusher:

1. Mobile jaw crusher frame

The frame is a four-wall rigid frame with upper and lower openings, which is used to support the eccentric shaft and bear the reaction force of the broken material. It requires sufficient strength and rigidity, and is generally cast as a whole with cast steel. Small crushers can use high quality cast iron to replace cast steel. The large frame needs to be casted in sections and firmly linked with bolts into the whole casting parts. The cast technology is complex.

2. Mobile jaw crusher jaw plate and side guard plate  

Fixed jaw and movable jaw are composed of jaw bed and jaw plate. Jaw plates are working parts, which are fixed on the jaw bed with bolts and wedge block. The fixed jaw bed is the front wall of frame, movable jaw bed is hanged around, requires sufficient strength and rigidity to support crushing force. Most of them are made of cast steel or cast iron.

3. Mobile Jaw crusher drive parts 

Eccentric shaft is the main shaft of the crusher, subjected to huge bending torque, made of high carbon steel. Eccentric part must be finished, heat treatment, bearing lining tile with babbitt alloy pouring. The eccentric shaft is equipped with a belt wheel at one end and a flywheel at the other.

4. Mobile jaw crusher regulating device

The adjustment device has wedge block type, pad type and hydraulic type, etc., generally adopts wedge block type, composed of two wedge blocks before and after. The front wedge block can be moved back and forth, push against the back plate. The back wedge is an adjustable wedge, which can be moved up and down. The inclined surface of the two wedges is inverted to fit. The screw makes the back wedge move up and down to adjust the size of the outlet. The outlet adjustment of small jaw crusher is realized by using the number of gaskets between the thrust plate support and the rack after increasing or decreasing.

5. Mobile jaw crusher flywheel

The flywheel of the jaw crusher is used to store the energy when the jaw moves, which is then used for industrial formation, so that the mechanical work is consistent and tends to be uniform. The belt wheel also acts as a flywheel. The flywheel is usually made of cast iron or steel, and the flywheel of mini jaw crusher is often made into a whole. When manufacture and install flywheel, should pay attention to static balance.
