Common Faults & Solutions for Sand Making Machines

Abnormal ammeter reading is a common fault or early fault symptom in the operation of a sand making plant, which often indicates that there is a problem in the operation of the equipment. If not handled in time, it may lead to more serious failures and affect the normal operation of the manufactured sand production line.

Main Causes:

① Improper feeding rate into the feed hopper of the sand making equipment, which leads to unstable load of the machine;

② Excessive material accumulation in the crushing chamber of the sand making plant, resulting in increased load and abnormal current;

③ Blockage of the discharge opening of the sand making equipment, which makes the material unable to be discharged normally and causes load increase;

④ Slippage of the V-belt of the sand making machine, which leads to insufficient power transmission and abnormal current display.

Overheating of bearings, motor or oil temperature in the oil return station is another common fault in the operation of sand making equipment. When the temperature exceeds the standard value, the machine must be shut down for inspection immediately to avoid damage to key components and affect the operation of the manufactured sand production line.

Main Causes:

① The motor of the sand making plant is in an overloaded state for a long time, which leads to excessive heat generation;

② Damage to the bearing housing of the sand making equipment, which affects heat dissipation and causes overheating;

③ Insufficient lubricating oil in the bearings of the sand making machine, which increases friction and leads to temperature rise.

In the long-term operation of the sand making plant, excessive vibration and abnormal wear of equipment are likely to occur, especially the wear of impeller, distributor and related wear-resistant parts of the sand making machine. Once such problems are found, inspection and troubleshooting shall be carried out in a timely manner to ensure the stable operation of the manufactured sand production line.

Corresponding Solutions:

① Inspect the wear condition of the impeller and distributor of the sand making equipment, and replace the corresponding throwing tips in time;

② Check the material accumulation in the crushing chamber of the sand making machine, adjust the feeding speed reasonably, and avoid excessive load caused by material accumulation;

③ Replace the shock absorption pads and main bearings of the sand making equipment, and tighten the loose bolts to reduce equipment vibration and avoid further wear.

In summary, the stable operation of sand making machines and sand making equipment is the key to ensuring the efficiency of the sand making plant and the manufactured sand production line. Timely discovery of faults, accurate analysis of causes and scientific solution implementation can effectively extend the service life of the equipment and reduce production losses.
