In the mining crushing industry, jaw crushers are widely used equipment. Their simple structure, convenient operation, wear resistance and durability are the reasons why most users choose them. The production efficiency and processing capacity of jaw crushers of different models and manufacturers are different. In order to meet the different needs of customers, our company has the following suggestions on how to improve the production efficiency and processing capacity of jaw crushers.
1. Equipment selection
(1) Choose the right model
Customers choose jaw crushers of appropriate specifications according to actual production needs, such as feed particle size, discharge particle size requirements, and output requirements. If the processing volume is large, a large-scale equipment should be selected; if the discharge particle size requirements are fine, a model with fine adjustment function can be selected.
Considering the performance characteristics of equipment from different manufacturers, select brands and models with advanced technology and reliable quality to ensure that the equipment maintains stable performance in long-term operation.
(2)Advanced crushing technology
Choose a jaw crusher equipment that adopts advanced crushing principles and technologies, such as optimized crushing chamber design, efficient jaw plate motion trajectory, etc. Advanced technology can improve crushing efficiency and reduce energy consumption.
For example, some new jaw crushers use a hydraulic adjustment system, which can easily adjust the size of the discharge port to adapt to different production needs and improve the flexibility and processing capacity of the equipment.
2. Equipment maintenance
(1)Regular inspection and maintenance
Develop a strict equipment inspection and maintenance plan, and conduct a comprehensive inspection of the jaw crusher regularly. The inspection content includes the wear of the jaw plate, the lubrication status of the bearing, the tightness of the transmission parts, etc. Timely discover and deal with hidden dangers of equipment failure, avoid the expansion of failures, reduce downtime, and improve the reliability and production efficiency of the equipment.
For example, conduct a weekly inspection of the equipment and perform comprehensive maintenance once a month.
(2) Replacement and maintenance of jaw plates
The jaw plate is a key component of the jaw crusher, and its degree of wear directly affects the crushing efficiency. Regularly check the wear of the jaw plate, and replace it in time when the wear reaches a certain degree. Choose a jaw plate material with good quality and high wear resistance, such as high manganese steel. At the same time, the jaw plate can be surface treated, such as surfacing a wear-resistant layer, to increase the service life of the fixed jaw plate. According to different material characteristics and production requirements, adjust the angle and spacing of the jaw plate to obtain the best crushing effect.
(3) Lubrication management
Establish a sound lubrication management system to ensure good lubrication of all parts of the equipment. Regularly check the quality and amount of lubricating oil, and replace or add lubricating oil in time. Select the appropriate lubricating oil brand and model, and lubricate reasonably according to the working environment and load conditions of the equipment. For example, under high temperature and high load working conditions, lubricating oil that is resistant to high temperature and heavy load should be selected. For the lubrication of key parts, such as bearings, gears, etc., an automatic lubrication system can be used to ensure the timeliness and accuracy of lubrication.
3. Operation management
(1) Reasonable feeding control
Control the feeding speed and feeding amount to avoid overfeeding or underfeeding. Overfeeding will cause equipment blockage and reduce production efficiency; underfeeding will not give full play to the performance of the equipment.
According to the processing capacity of the equipment and the characteristics of the material, reasonably adjust the parameters of the feeder to ensure uniform and stable feeding. An automatic feeding control system can be used to achieve precise feeding.
Control the particle size of the feed to prevent oversized or undersized materials from entering the crusher. Oversized materials will increase the load of the equipment and reduce the crushing efficiency; undersized materials may form accumulation in the crushing chamber, affecting the normal operation of the equipment.
(2) Optimize crushing process parameters
According to different materials and production requirements, adjust the working parameters of the jaw crusher, such as the stroke, speed, and discharge port size of the jaw plate.
Through experiments and optimization, find the best combination of process parameters to improve crushing efficiency and processing capacity. Use modern automation technology to monitor and adjust the working parameters of the equipment in real time to achieve intelligent crushing production.
(3) Operator training
Provide professional training for jaw crusher operators to familiarize them with the performance, operation methods, and maintenance requirements of the equipment.
The training content includes equipment start-up, stop, feed control, parameter adjustment, troubleshooting, etc. Improve the technical level and sense of responsibility of operators to ensure the normal operation and efficient production of equipment.
Regularly organize operators to conduct technical exchanges and experience sharing to continuously improve operating skills and management level.
4. Material handling
(1) Material pretreatment
Pre-treat the materials entering the jaw crusher, such as screening and iron removal. Removing impurities and oversized particles in the material can reduce equipment wear and blockage and improve crushing efficiency.
For materials with high viscosity, drying or humidification can be used to improve the fluidity of the materials and facilitate crushing and transportation.
(2) Material matching and mixing
According to the characteristics and crushing requirements of different materials, reasonable material matching and mixing are carried out. For example, mixing and crushing materials with higher hardness and materials with lower hardness can improve crushing efficiency and reduce the wear of the jaw plate.
Control the moisture content of the materials to avoid excessive moisture or dryness. Overly wet materials are easy to clog the equipment, and overly dry materials will produce more dust, affecting the normal operation of the environment and equipment.
5. Auxiliary equipment
(1) Matching suitable feeders and conveyors
Choose feeders and conveyors that match the jaw crusher to ensure smooth and stable material transportation. The feeding capacity of the feeder should be adapted to the processing capacity of the crusher to avoid insufficient or excessive feeding.
The conveying speed and bandwidth of the conveyor should be reasonably selected according to the flow rate and particle size of the material to ensure that the material can be transported out in time without accumulation and blockage.
For example, for large jaw crushers, vibrating feeders and belt conveyors can be selected to match and improve production efficiency.
(2) Install dust removal equipment
The jaw crusher will generate a lot of dust during operation, which will not only pollute the environment, but also affect the normal operation of the equipment and the health of the operators. Installing efficient dust removal equipment, such as bag dust collectors, cyclone dust collectors, etc., can effectively reduce dust emissions and improve the quality of the production environment.
Regularly maintain and clean the dust removal equipment to ensure its normal operation. At the same time, auxiliary measures such as spray dust reduction can be used to further reduce dust pollution.
(3) Automatic control system
Introduce advanced automatic control systems to centrally control and manage jaw crushers and auxiliary equipment. The automatic control system can realize the automatic start, stop, feeding control, parameter adjustment, fault alarm and other functions of the equipment, and improve the operation efficiency and reliability of the equipment.
By real-time monitoring of the equipment's operating status and production data, problems can be discovered and handled in a timely manner, the production process can be optimized, and production efficiency and product quality can be improved.
