Green and energy-saving
Selecting high-quality motors, excellent performance of the power system, low noise during operation, and significant energy-saving advantages.
Working Principle
The raw material firstly enters into the vibrating feeder equipped with pre-screening function, in which the part with smaller particle size will be automatically screened out and directly excluded by the lateral belt conveyor; while the material with larger particle size enters into the crushing chamber of the crusher, and after fully crushed in the chamber, it will be transferred to the subsequent equipment through the belt conveyor for the secondary crushing, or directly transported by the belt conveyor to complete the primary crushing operation. If the equipment is equipped with vibrating screen system, the crushed materials will be graded by the vibrating screen first, and the materials with excessive particle size will be returned to the feeder for re-crushing, and the materials that meet the standard of particle size will be output through the unloading belt directly.
FAQ
Q: Crawler type mobile stone crusher operation suddenly stop, what may be the reason?
A: (1) Motor overload, due to too large a feed or too hard material caused by the clogging of the crushing chamber, triggering the overload protection; (2) Hydraulic system failure, such as insufficient hydraulic oil, pipe leakage or hydraulic pump damage, affecting the operation of the track or crushing mechanism; (3) Electrical system problems, such as poor line contact, blown fuse, etc.. Solution: Cut off the power supply, check whether the feeding port and crushing chamber are blocked and cleaned up, check the hydraulic oil level and pipeline sealing, check the electrical wiring connections, and contact professionals for overhaul if necessary.
Q: How can I reduce the noise when the equipment is operating?
A: Excessive noise may be caused by the wear of several parts or unstable installation. (1) Regularly check and replace the worn hammerhead, liner, adjust the gap to a reasonable range; (2) Monitor the lubrication status of the bearings and replenish or replace the lubricating grease in time; (3) Ensure that the equipment is installed on solid ground, strengthen the ground bolts, and install shock absorbing pads to reduce vibration noise if necessary.
Q: How to adjust the uneven granularity of the crushed material?
A: Uneven granularity of material is mainly related to crushing parameters, state of components and feeding situation. (1) For jaw crusher, the size of discharge opening can be adjusted by adjusting bolt or hydraulic system to narrow the gap and make the material finer. (2) In case of cone crusher or impact crusher, check the wear degree of the liner in the crushing chamber, if the wear is inconsistent, it will lead to the deviation of particle size, and need to replace the liner in time; (3) Keep the feeding material uniform and stable, avoid the fluctuation of the feeding material to affect the crushing effect, you can adjust the amplitude or frequency of the vibrating feeder to accurately control the feeding speed.
Q: What should I do if the tracked mobile rock crusher is difficult to move in muddy or steep slopes?
A: Even though the crawler is designed to cope with complex terrain, it may still slip under extreme working conditions such as mud or steep slopes. (1) Prioritize checking the track tension. If it is too loose, it will lead to a loss of grip, so you can adjust the track tension to the right range in time through the hydraulic adjusting device that comes with the equipment; (2) Thoroughly clean the slit of the track plate and the debris such as silt and gravel attached to the surface to restore the effective friction between the track and the ground; (3) When working on steep slopes, keep the equipment traveling longitudinally along the slopes to avoid lateral movement leading to side slipping, and if necessary, lay anti-skid steel plates or gravel bedding under the tracks to enhance the ground support; (4) If the equipment is equipped with electronic anti-skid control system, make sure that the function is activated and working normally.
Q: What checks need to be done to restart the equipment after a long period of decommissioning?
A: A systematic inspection must be carried out before restarting the equipment after a long period of disuse to avoid the risk of potential failure. (1) Focus on checking the solidity of the connection of each part, especially check the fastening bolts of the crushing chamber, conveying belt, track assembly and other key parts, and tighten the loose parts in time. (2) Comprehensively replace the oxidized and deteriorated hydraulic oil and lubricating grease, and simultaneously clean up the impurities deposited in the oil tank and oil supply pipeline. (3) Carry out function test on the electrical system, verify the insulation performance of the motor, the sensitivity of the switch contacts and the accuracy of the sensor signal, and check the aging or damage of the line insulation layer. (4) Manually pan the rotor of the crusher to confirm that there is no jamming phenomenon in the moving parts, and then carry out no-load test run for 5-10 minutes to closely monitor the vibration amplitude of the equipment and the abnormal noise, and then put the material into production only after the parameters are stabilized.
