During the operation of the grinding unit, the unit operator is responsible for the equipment and production specifications. Therefore, in order to ensure the normal progress of the grinding process, the operator needs to continuously check, maintain and adjust the grinding machine and its ancillary facilities, work indicators and product quality. The main contents of inspection and maintenance are: 1) Inspection of equipment and its ancillary facilities. 1 Grinding machine inspection: a. Pay attention to check the looseness of each part of the screw, especially the looseness and breakage of the lining screw, causing leakage; b. Check the wear condition of the returning head; c. Pay attention to the discharge of the grinding machine Thick or spit. 2 Oil supply system inspection: a. Always check whether the oil pressure is normal. b. Check the oil quantity and oil temperature; c. Check whether the main shaft oil flow distribution is uniform; d. Oil viscosity and cleanliness. 3 motor electrical inspection. Mainly check the motor temperature, the temperature rise does not exceed the allowable value. 4 Classification equipment inspection: a. Check whether the spiral classifier blades fall off, whether the rotation is stable; b. Whether the cyclone feeding pressure is stable, whether there is wear or blockage. 2) Inspection of grinding load. The load of the grinding unit includes the original ore amount and the amount of sand returned. It is an important condition to achieve a good grinding effect to ensure that the grinding load is consistent and stable. 1 The ore supply should be kept constant and stable, and the amount of ore should be checked regularly; 2 observe the change of the ore size at any time, adjust it in time, and do as much as possible to discharge the silo as much as possible. 3 Diligently look at the returning sand and hydration, so as to achieve the balance of the original ore, return sand and overflow. 4 Pay attention to the motor current and the sound change of the mill. According to this, judge the load of the mill and eliminate the “flatness†in the initial stage. 3) Quality inspection of grinding graded products. The quality of grinding products mainly refers to the quality fraction and fineness of the graded overflow. These two indicators directly affect the quality of the subsequent sorting operations. They must be measured diligently, diligently observed, diligently tested and diligently adjusted. In short, during the work, the operator should do diligent walking, diligent inspection, diligent testing (testing), diligent adjustment, diligent observation, pay attention to sound changes, ensure that the grinding mineral group is in the best working condition, and obtain good grinding. effect.
