Jaw crusher is a common crushing equipment in mining, construction, metallurgy and other industries, and its performance directly affects production efficiency and cost control. Therefore, when choosing jaw crusher equipment, various factors must be carefully considered to ensure that the purchased equipment can meet production needs and has good performance. Factors to consider when selecting a jaw crusher include production capacity, equipment quality, material characteristics, and local environmental protection policies.
Specifically:
● Production capacity: The production capacity of a jaw crusher depends on its specifications, speed, meshing angle and other factors. Choosing the right production capacity can meet the needs of the production line and avoid overcapacity or undercapacity.
● Equipment quality: The quality of wear-resistant materials such as jaw plates, liners, tooth blocks and other parts directly affects the service life and maintenance cost of the equipment. Choosing high-quality parts can reduce the trouble of frequent replacement.
● Material properties: The moisture content, volume and strength of the material will affect the selection of a jaw crusher. The feed size and discharge size need to match the characteristics of the material to ensure that the equipment can work effectively.
● Local environmental protection policy: Jaw crushers will generate dust and noise during operation. Choosing equipment that meets environmental protection standards can reduce environmental pollution and avoid rectification.
Common fault handling
● Severe wear of the jaw plate: Replace the worn jaw plate in time, and adjust the gap of the discharge port to ensure that the crushing effect and the discharge particle size meet the requirements.
● Bearing heating: Check and add lubricating oil regularly to ensure sufficient lubrication; if the bearing is found to be damaged, it is necessary to replace it with a new qualified bearing in time.
● Motor vibration is too large: Check the rotor balance, tighten all connecting bolts, ensure that the equipment is installed firmly; ensure that the equipment runs on a solid and flat foundation.
● Discharge is not smooth: Stop the machine to clean up foreign objects in the crushing chamber, and reasonably adjust the size of the discharge port according to the crushing requirements.
● Main machine shutdown: Clear the blockage of the discharge port, tighten or replace the triangular tape, reinstall or replace the fixing bushing, adjust the voltage of the workplace, replace the bearing, etc.
● Output does not meet the standard: Check the hardness of the material, motor wiring, discharge port size, jaw plate position, etc., and make corresponding adjustments.
● Broken movable jaw: Check and replace the broken movable jaw or related components to ensure that the equipment operates within the allowable load range.
