Trommel screen is a kind of equipment commonly used in beneficiation. Through the continuous rotation of the screen body, large pieces of waste rock can be thrown out, greatly improving the next separation operation. The roller drum screen mainly consists of motor, reducer, roller device, frame, screen and inlet and outlet. During operation, the motor connects the reducer with the roller device through the coupling, and drives the roller device to rotate around its axis. The materials are turned over and rolled, and the materials are screened out one by one through different meshes. The materials stuck in the mesh can also be ejected to prevent blocking.
Ⅰ. Preparation before commissioning
Ⅱ. No load test run
The following items shall be checked during 1-2 hours of test run.
a. When the screening machine is in stable operation, start up the feeding and discharging equipment, and carry out feeding and commissioning.
b. Close the seal isolation cover after normal discharging (during normal operation, the seal isolation cover shall always be in the closed position).
c. Check the discharge particle size and whether there is leakage and dust.
d. Operate for half an hour, check all parts carefully and deal with problems in time.
e. During the working process, the operation condition shall be checked frequently. In case of abnormal operation or abnormal sound, the machine shall be shut down for inspection in time to find out the cause and eliminate the fault.
