1, equipment to lay the foundation
The jaw crusher is usually installed on a concrete foundation with a drain tank on the foundation. The slope is less than 50 degrees. Since the vibration of the crusher is large, it is necessary to isolate the foundation of the crusher from the foundation of the equipment.
2, rack installation
During installation, some vibration-absorbing things should be placed between the frame and the concrete, such as hardwood, rubber, etc. Mounting the frame on the foundation or in the horizontal and vertical position on the wooden seat needs to meet the installation requirements of the equipment. Should be less than 0.2mm.
3. Assembly point of eccentric shaft and bearing
Before the shaft and bearing assembly, it is necessary to study the sliding bearing, then place it in the sliding bearing housing, and use the level to check the level and coaxiality of the placement. If the measurement meets the requirements, mount the eccentric shaft on the bearing and apply red powder on the journal to see the fit between the shaft and the bearing. If the surface of the plain bearing is too high, further scratching is required until the high point between the contact faces disappears. Finally, a certain amount of lubricant is added between the bearing housing and the bearing to reduce shaft wear. The contact area between the eccentric shaft and the frame should be not less than 80%, and the gap between them should be less than 0.07 mm.
4, the dynamics of the installation points
The assembly of the moving parts is carried out in advance, and the movable raft, the movable raft, the movable raft, the bracket, and the like are assembled on the ground, and then by using a crane or a crane. On the rack. For plain bearings, it is first necessary to study the bearings and housings in order to mount the plain bearings in place and to detect the concentricity and inclination of the plain bearing assembly. The tilt is guaranteed to be 0.2 mm and coaxiality is required. Less than 0.06 mm completes the assembly of the movable jaws.
5, the installation of the crankset
The jaws of the jaw crusher are part of the crusher and are used directly to break the ore. Its structure is simple, but since it is often in contact with ore, it needs to be replaced frequently. The cross-sectional structure of the tooth plate has two kinds of smooth surfaces and lattice type surfaces. Due to its heavy weight, it needs to be made into an easy-to-replace structure. The tooth plate is fixed by bolts or wedges and is fixed to the front wall or the movable side of the frame, and the contact surface between the two must be straight. If the contact point is high, it needs to be processed in time. In addition, some aluminum plates or the like may be used between the rear surface of the fixed tooth plate and the front wall of the frame to ensure the tightness of the combination.
