How to adjust the discharge port of the cone crusher?

January 08, 2020

During the crushing process, the moving cone liner and the fixed cone liner are continuously worn, so that the discharge port is gradually increased. In order to ensure a certain product size, it is necessary to continuously adjust the size of the discharge port with the wear and tear. The adjustment of the discharge port is realized by means of the zigzag thread lifting and lowering cone liner between the adjusting ring and the support sleeve.

In order to lubricate the toothed threads and to facilitate adjustment and disassembly, the threads must have sufficient clearance.

Adjusted port of discharge, using methods based lead wire ball, to the crushing chamber through the port of discharge at the discharge mouth size measurement. The new processed liner can be measured at one point, and the unprocessed or worn liner should be measured between 6 and 8 points. After the discharge port has reached the size requirement, the adjustment ring is locked by the lock cylinder, otherwise it is not allowed to start.

Actually, a wiper assembly that refuses to move might have a simple blown fuse. But usually fuses don't blow on their own. Even at full stall, the current draw of the motor should be well below the fuse's rating. If the fuse is blown, odds are there's something else wrong, like a shorted wiper-motor armature or faulty wiring anywhere along the harness between the motor and the switch. Even a mechanical problem like a seized bushing can make a fuse eventually fail.

The fuse is okay, or you've replaced it with one that has the appropriate amp rating. There's still no action? With the wipers and ignition on, whack the motor assembly with the handle of a screwdriver or a rubber mallet. If that gets things moving, you've got a bad commutator or an open winding on the armature. When the motor parks, if the brushes are sitting on the bad segment, no current flows. Whacking the whole business smartly can sometimes jolt things into motion. Because there are often a dozen windings on the armature, the motor runs fine until the next time it comes to rest on the bad spot.
