Rotary screen is the most widely used sand screening equipment, which is suitable for sand and stone separation in river, reservoir and coal yard. Its structure design is relatively simple, and generally consists of inlet, outlet, motor, reducer, frame, drum device and other parts, which is mostly used in gravel production line or sand production line.
It should be noted that when the sand screen is in stable operation, attention should be paid when feeding and discharging. After the equipment discharging normally, we need to close the isolation cover to check whether there is sand leakage and dust.
Preparation before sand screen operation:
1.After all parts of the drum screen are installed and checked to be qualified, the test run can be carried out. Before the commissioning, check whether the components are correctly installed as shown in the drawings, the fasteners are reliable, and whether there are obstacles around the screen body that hinder the operation of the drum screen;
2.Check that the bearing pedestal and gearbox should be well lubricated and the gearbox oil level should be appropriate;
3.By manually rotating the screening cylinder, observe whether the roller screen has the phenomenon of jamming and friction. If so, it can be adjusted by adjusting the bolts;
4.The power connector should be firm and reliable, with good insulation and correct grounding.
