Portable jaw crusher is mainly used for medium-sized crushing of various ores and bulk materials, and is widely used in mining, smelting, building materials, highways, railways, water conservancy and chemical industries. The performance characteristics of jaw crushing machine are large crushing ratio, uniform product particle size, simple structure, reliable performance, easy maintenance and low operating costs.
Portable jaw crusher machine has a harsh working environment and various faults often occur during operation. In order to ensure the stable operation of portable jaw crusher machine and improve equipment performance, it is particularly important to do a good job of daily maintenance of portable jaw crusher machine! Jaw crushing machine mainly has important components such as eccentric shaft, pulley, frame, flywheel and reset spring, toggle plate, fixed jaw plate and movable jaw plate. Maintenance is generally divided into three different degrees of maintenance, minor repair, medium repair and major repair.
1. Minor repair
Minor repair mainly includes checking and repairing the corresponding adjustment device, making certain adjustments to the discharge port gap, replacing the worn liner and thrust plate, repairing and replacing the corresponding transmission components, cleaning the individual parts of the jaw crushing machine, re-applying the lubricating oil of the entire machine, repairing and adjusting the lubrication system of the machine, etc.
Generally, the frequency of minor repairs is between half a month and one month, and it is handled according to the overall operation of the Jaw crusher machine.
2. Medium repair
Medium repair not only includes all the items of minor repairs, but also replaces the worn structures of the jaw crushing machine, such as the tie rod, liner, bushing, thrust plate, etc., and performs certain inspections on the turning, grinding and casting eccentric bearings. Some bearings such as the connecting rod head bearing and the power bearing must be handled accordingly.
The interval time of medium repair should also be determined according to the overall wear and use of the jaw crusher machine. Generally, once a year can meet the operation needs of the machine.
3. Overhaul
The main contents of the overhaul include all the items of the medium repair, replacement of the eccentric shaft of the jaw crushing machine, reinforcement casting of the Babbitt alloy on the upper part of the connecting rod head, and replacement of all worn parts and component structures. There is no specific time limit for the overhaul, which is based on the degree of normal inspection.
As a rough crushing equipment for sand and gravel raw materials, the jaw crusher machine has a large workload and high frequency of use, so the wear and failure rate is naturally high. Only by fully understanding the causes and solutions of equipment failures can we put it into production faster and reduce the losses caused by maintenance and shutdown.
