When replacing the mantle and concave of the cone crusher, the wear of the fixed cone, adjusting ring, locking thread, counterweight and counterweight guard must be checked. If the wear is serious, replace it with a new one, and then install the liner, which can reduce the time for secondary replacement and disassembly, saving time and effort. After the liner is installed, it is necessary to check whether the center of the liner is aligned, otherwise the liner will collide during operation, resulting in serious wear of the liner.
· Replacement of concave
The concave can be replaced in the field. Unscrew the adjusting screw sleeve installed on the upper frame (note that it is turned counterclockwise), remove the hopper assembly in the upper chamber, lift the adjusting screw sleeve with the hoisting equipment, remove the adjusting screw sleeve supporting plate bolts, and then take out the concave is replaced. When assembling, the outer surface should be cleaned, and the surface of the screw thread should be adjusted with butter, and fixed in reverse order.
Notice
There is a U-shaped screw on concave to put it on the adjustment ring, and zinc alloy is injected between the two to make it tightly combined. When installing or replacing the concave, check its fastening condition after working for 6-8 hours. And tighten the U-shaped screws again.
· Replacement of mantle
Mantle are field replaceable. Lift out the main shaft components and place them on a solid support platform, taking care not to damage the moving cone and spherical surface, and at the same time block all the oil holes with cloth to prevent dust and impurities from entering, then remove the distribution plate, lock nut, and lock washer in turn , fusible gasket, weld two lifting lugs on the old plate at a distance of 180°, and then the mantle can be lifted out, and the new mantle can also be welded on the two lifting lugs at a distance of 180°. lugs, then install in the reverse order of disassembly, and cut off the two lugs when finished.
Notice
The mantle is fixed on the cone body with a cone head, and zinc alloy is cast between the two. After the newly installed or newly replaced mantle has been working for 6-8 hours, its fastening condition should be checked, and if looseness is found, it should be repaired immediately fasten.
The mantle and concave are important parts of the cone crusher. During the operation of the cone crusher, it should be noted that the materials put into the equipment must meet the crushing requirements. Otherwise, it will cause failures such as the mantle rolling off the concave, equipment shutdown and so on. At the same time, the feeding of the cone crusher must be uniform, and the ore must be fed in the middle of the distribution plate. The material cannot directly interact with the mantle and the concave to prevent uneven wear.
Shanvim Industry (Jinhua) Co., Ltd., established in 1991. The company is a wear-resistant parts casting enterprise. The main products are the wear-resistant parts such as mantle, bowl liner, jaw plate, hammer, blow bar, ball mill liner, etc..
