Adjustment and maintenance of the discharge port of the cone crusher

February 28, 2024

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 make the toothed thread lubricated, and the adjustment and disassembly are convenient, the thread 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.
Cone crusher overhaul, medium repair, minor repair content: the inspection cycle should be determined according to the actual conditions of the equipment.
The minor repair cycle is conducted every half month to one month and includes:
(1) Check the bowl tile; (2) Check the wear of the taper sleeve and the straight sleeve and check the gap. (3) Check the meshing clearance of the bevel gear; (4) Check the clearance of the transmission bushing; (5) Check the hydraulic device (if the hydraulic device is not provided) and the lubricating device or replace the lubricating oil; (6) Clean the main parts.
The medium repair period is about 4 to 6 months, and its main contents include:
(1) Replace the liner; (2) Repair or replace the eccentric bushing, taper sleeve and straight sleeve; (3) Repair or replace the bowl tile and dustproof device; (4) Repair or replace the bevel gear, drive shaft and bearing bush (5) repairing the adjustment ring and the support sleeve thread; (6) performing all inspections and treatments on the minor repair items; (7) disassembling the motor, blowing dust and descaling, and checking the bearing bush gaps; decomposing the oil switch, cleaning and handling defects; Electrical adjustment and testing; inspection and repair of switchboards and other cables.
The overhaul is about four years or based on actual conditions. Its contents include:
(1) repair or replace the frame and the basic part of the problem; (2) carry out all inspection and treatment of the medium repair project, and carry out technical transformation; (3) replace the stator coil of the motor (determined according to preventive test) and dip Paint; decide whether to replace the rotor shaft according to the actual situation. The ring is locked, otherwise it is not allowed to start.
