Wheel sand washing machines are used extensively in sand and aggregate washing and dewatering operations. There are a number of issues that may come up while using such machines, which may impact efficiency and quality of output.
Problem 1: excessive loss of fine sand
Fine sand particles may get carried away in the wastewater, causing a decrease in output and changes in particle size distribution. This problem may be resolved by adjusting the flow of water and washing time and adjusting the overflow weir height. It may also be worthwhile to install a fine sand recovery system in such cases.
Problem 2: inadequate cleaning effect
There may be instances where clay, silt, and other impurities remain in the washed sand output. This problem may be resolved by extending washing time and/or rotating wheel speed, and by improving water pressure and volume. It may also be worthwhile to install a prescreen in front of the washing plant to filter out excessive mud from the raw material before it enters the washer.
Problem 3: bearing damage or overheating
Bearing components are constantly exposed to water, sand, and mud, and may get damaged due to such exposure. This problem may be resolved by using high-quality bearings with seals and by improving daily maintenance activities.
Problem 4: uneven and unstable operation
Vibrations and abnormal sounds during operation may have a significant impact on equipment longevity. It may be worthwhile to check the level of the equipment and balance it, and to check bolts and shaft alignment, and wheel buckets. It may also be worthwhile to check that the equipment is not overloaded during operation.
Problem 5: high water consumption
Excessive consumption of water may impact efficiency and increase operational costs. This problem may be resolved by using a water recycling system and/or a settling pond to recycle and reuse water effectively in conjunction with high-efficiency sludge treatment equipment.
