The vertical compound crusher is an advanced equipment that integrates the screenless design and adjustable fine crushing function. It is not only competent for the fine crushing of raw materials and clinker in the cement industry but also widely used in the fine crushing of various medium-hard materials such as dolomite, coke, lead-zinc ore, serpentine, blast furnace slag, coal gangue, phosphate rock, etc., especially in the artificial sand making of hard limestone, dolomite, granite, basalt and other materials and the processing of highway pavement stones.
However, like any mechanical equipment, vertical compound crushers inevitably encounter some faults during operation. Timely identification and resolution of these faults are essential to maintaining efficient and stable equipment operation and extending its service life. The following is a detailed description of several common faults and their resolution strategies:
Vertical Compound Crusher Abnormal Noise
Phenomenon description: During the vertical compound crusher for mining regular operation, if you suddenly hear abnormal sounds in the crushing chamber, this is often a warning signal that cannot be ignored. This sound may appear as a sharp sound of metal collision, continuous friction sound, or irregular vibration sound, indicating a problem inside the vertical compound ore crusher that needs to be checked and dealt with in time.
Solution: First, stop the vertical compound rock crusher immediately and cut off the power supply to clean the residual materials in the crushing chamber. Then, check whether any unbreakable foreign objects are mixed in to ensure the purity of subsequent feeding. At the same time, carefully check the fastening state of the liner and whether the gap between the hammer head and the liner is appropriate. Pay attention to whether the wear-resistant liner is firmly in place and adjust or replace it if necessary.
Vertical Compound Crusher Particle Size Of Material Discharged Is Too Large
Phenomenon description: During the average production of vertical compound crusher for cement crushing, if the discharge particle size exceeds the expected setting range, the particles are too large and unevenly distributed, directly affecting the subsequent process and product quality. This phenomenon usually indicates that the vertical compound gypsum crusher fails to achieve the expected pleasing crushing effect during crushing process, requiring immediate troubleshooting.
Solution: To solve this problem, the crushing effect can be optimized by adjusting the gap between the front and rear impact racks. If the liner or hammer is severely worn, it should be replaced in time to restore the average discharge particle size. In addition, fine-tuning the position of the impact rack to the optimal state is also an effective means of ensuring that the discharge fineness meets the standard.
Vertical Compound Crusher Hammer Head Wears Too Fast
Phenomenon description: During the continuous operation of vertical compound limestone crusher, the hammerhead, as a critical component directly involved in the crushing operation, will gradually wear out due to frequent impact, extrusion and friction of the material. When the wear rate exceeds the normal range, the hammerhead wears too fast, affecting the crushing efficiency and product quality and increasing the equipment maintenance cost and downtime.
Solution: To extend the service life of the hammer, it is necessary to control the material quality from the source to prevent metal lumps and other debris from entering the crushing chamber. At the same time, using high-quality wear-resistant materials such as high-carbon manganese alloy cast steel to make the hammer can significantly improve its wear resistance. In addition, reasonably setting the speed and power of the rotor to ensure that the hammer obtains an appropriate impact hardening effect is also the key to extending the service life.
Vertical Compound Crusher Bearing Overheating Or Damage
Phenomenon description: During the continuous and high-intensity operation of tvertical compound quartz crusher, the bearing is the core of the supporting and rotating parts, and its health directly affects the overall operating efficiency and stability of the equipment. When the bearing temperature is too high, or there are obvious signs of damage, if adequate measures are not taken immediately, it may cause equipment shutdown, increase maintenance costs, and even cause more serious mechanical failures.
Solution: As the vertical compound dolomite crusher operates under harsh conditions, the maintenance and care of the bearings are essential. During installation, ensure the balance of the rotor and the bearings, and select bearings with strong load-bearing capacity and excellent self-aligning performance. Check the bearing temperature regularly and add an appropriate amount of clean grease (filling it to 50% of the bearing seat volume) to reduce friction and wear and prevent overheating. If the bearing is damaged, it should be replaced in time, and the wear of related parts should be checked to avoid chain failures.
