Vertical compound crusher has the double function of fine crushing and rough grinding, and the price is affordable, which is the best choice for many small and medium-sized stone factories. There will inevitably be some small faults in the operation of compound crusher, if not solved in time, it will affect the operation efficiency and service life of equipment. In this text, according to years of practical experience, Luoyang Dahua engineers summed up some common faults and solutions for you.
Fault 1: The compound crusher is abnormal
In the process of running, if abnormal sound is found in the crushing chamber, it should be stopped immediately and turned off the power, and the crushing chamber should be cleaned first; Secondly, check whether there is non-broken material into the crushing chamber; Then, check the tightness of the lining plate, as well as whether the clearance between the hammer head and the lining plate is within a reasonable range, and check whether the wear-resistant lining plate falls off.
Fault 2: Discharge particle size is too large
Vertical compound crusher is a fine crushing equipment, if it is found that the discharge is too large, beyond the set range, you can adjust the clearance between the back impact frame, or replace the badly worn lining plate and plate hammer to adjust the discharge. You can also adjust the position of impact frame to make it in the appropriate position, so as to ensure the fineness of discharge particles.
Failure 3: Hammer head failure
Vertical compound crusher breaks the material by a series of strike, impact, extrusion and other forces between the hammer and the lining plate, so the failure of the crusher hammer head is inevitable. When feeding compound crusher, to avoid metal blocks and other sundries into; Secondly, wear resistant materials such as high carbon manganese alloy cast steel should be used as hammer head materials to improve the wear resistance coefficient of hammer head. The speed and power of the rotor will also affect the service life of the hammer head.
Fault 4: Bearing problems
The vertical compound crusher works under the bad conditions of large impact load, large vibration, high speed and much dust for a long time, which makes the wear of rotor bearings more serious. Bearing damage is mainly caused by the imbalance of the rotor or bearing installation, the rotor must pay attention to balance when installing. In addition, if the bearing overheats, the right amount of grease should be added. In standard terms, grease should be filled with 50% of the bearing seat volume, and attention should be paid to the cleaning of lubrication grease.
