1、1Jaw CrusherInstruction ManualYou should read this instruction manual carefully before operating to make the crusher work properly.Application It is applied to crush maximum, medium and minimum rocks and ores etc that the pressure resistance strength is under 250Mpa.P E X S Feeding mouth length Feed
2、ing mouth widthToggle plate pushing typeminimum (size of final product)Jaw crushercrusherWorking principles and structure:The crusher is mainly made of frame、moving jaw、eccentric shaft、tooth plate、toggle plate and adjustment set etc(see fig1、2、3、4). The motor through belt and flywheel drives the ecc
3、entric shaft to rotate, and the eccentric shaft will drive the moving jaw to move at a regular track. In this way, the materials in the crushing cavity can be crushed and then discharged from the 2discharge opening.Frame: we have two kinds of frame, one is jointing, and another one is steel cast. Th
4、e fixed jaw plate fastened by wedge-shaped check plate is installed to the front of the frame. The upper and lower cheek plates are installed at the right and left side of the frame to protect wall of the frame.Moving jaw: As showed as fig 2、5, the moving jaw is made of cast steel, movable jaw plate
5、 is fastened to the front of the moving jaw by bolt. Assembly consisting of bearing, cover, eccentric shaft is installed to the upper part of it. The lower part of it is connected with frame through toggle plate, drawback rod and spring etc.Toggle plate: it is made of accurate cast iron. It is insta
6、lled in middle of the adjust base and mainframe. Its not only the component that spreads the strength, but also the insurance part of the crusher. The toggle plate will broke up first to protect other parts as a result of overload, when some unbreakable materials get into the crusher, causes overloa
7、d for an instant.Adjustment set: it is used to adjust the discharge opening. We have two ways to do it. One is to loosen wedge bolt and move wedge up and down, then make the adjusting base move for adjusting.Another one is to put in or take out several adjusting spacers to make the adjusting base mo
8、ve for adjusting. The fixed and movable jaw plates with teeth are both made of manganese steel. The fixed jaw plate is installed to the front of frame, and the movable jaw plate 3is fastened to the moving jaw. They are designed symmetrically, so if one end of them is frayed, another end also can be
9、used.Technical Parameter: PE、PEX、 ZG-PE、 ZG-PEX jaw crushers technical parameter is listed below.1、model 2 、feeding mouth size (LW) 3 、adjusted discharging mouth 4、max feeding size 5、capacity 6、rolling speed (r/min) 7、electric power (KW) 8、overall size (LWH) 9、weight(kg)Note: ZG indicates steel cast
10、 frame. Installation, Debugging and Trial OperationWhen your equipment arrives, it should be checked immediately according to packing list to see that all components have been received and that there is no evidence of damage in shipment. These steps mentioned below should be noticed:Because the mach
11、ine vibrates heavily during operation, it should be installed on the concrete base. In order to reduce vibration, when installing the equipment, its better to put a rubber belt or wooden block between the crusher and the concrete base as a cushion material. The height, depth and area of the concrete
12、 base should be calculated according to condition of the earth. Installing size of the machine refer to the foundation diagram. 4Discharge tank in concrete base is in a right position to be sure the moving jaw is free to move. Put some metal plates on the walls of discharge tank, and those metal pla
13、tes should be placed in a certain angle to make sure the materials can be discharged smoothly. The discharge mouth size should be adjusted to meet the requirement of customers. We have two ways for adjusting. One is to use wedge to adjust. First unscrew the drawback pod nut, then unclamp the spring,
14、 loosen the wedge bolt, adjust the height of the wedge bolt and get discharging opening required. Also we use two wedges for adjusting. You must make sure two wedges are parallel, if either of them is declining, the load on them is not even, and it will damage other parts. Another one is use spacer
15、to adjust. Loosen the wedge bolt, wedge, adjusting base and spring, the tip bolt push the adjusting base back, put in or take out several spacers, then fasten the tip bolt, wedge, wedge bolt, and adjusting base to finish adjusting. The spring needs some pre-force to prevent the toggle plate from fal
16、ling. But the force should not be too big, just big enough to eliminate the striking noise between parts. The crusher should run for more than 2 hours without load after installation and adjustment. The temperature of the bearings cant exceed 70. Check to be sure all the nuts and bolts are tight, then take a trial run with load and recheck to be sure all the fasteners are tight. 5Operation:You should read and understand each of operating rul
