Crusher is the main means of production for mineral enterprises, especially in modernized production today. Crusher is also the important sign measuring the level of production technology in mine enterprise. Thus the management and maintenance of the crusher is the basic work in the production and operation of enterprises. It is a guarantee of product quality and also is the important way to improve the enterprise economic benefit .
1. The transmission
Eccentric shaft is the spindle of the crusher,which is bearing huge torsion and made by the high-carbon steel. Eccentric shaft must be processed by finishing, heat treatment and the bearing should pouring by the use of the babbitt metal. There is a pulley at one side of the eccentric shaft ,and the other side with the flywheel.
2. Jaw plate and side guard board
Dynamic jaw and static jaw are all made up of jaw bed and jaw plate, jaw plate is the working part and fixed to the jaw bed with bolts and wedge iron. The jaw bed of dynamic jaw is the front wall of the frame,and the jaw bed of the static jaw hangs round periphery,which must have enough strength and stiffness to sustain the crushing force, and is mostly cast with steel or iron castings. Jaw board and side guard board contact directly with the raw material of the parts, the hardness and wear-resisting degree of which is relatively good.
3. The flywheel
The flywheel of jaw crusher is for store the banking energy of dynamic jaw to reuse in the formation of industrial and make the machinery work uniformly. The pulley plays the role of the flywheel. The flywheel usually cast with cast iron or cast steel, the flywheel of mini-machines hongxingly made into a whole. We should pay attention to the static balance when installing the flywheel.
4. Adjusting device
Adjusting device also called adjusting screw.The common adjusting device includs wedge type,subplate type and hydraulic type,and the wedge type is the hongxing choose. The wedge adjusting device is composed by the former and the later wedge block,the former wedge block can be moved back and forth and hold out against push board. The later wedge is a adjustable wedge,which can move up and down. The inclined planes of the two wedge fit backward so that the wedge to move up and down with the help of screw to adjust the material mouth size.
