High Speed Mixer

Before running the sieve machine, check: including equipment hygiene, all parts of the connecting bolts are complete, tight and flawless, check whether the exciter is flawless, check whether the tension springs are not damaged, lack, cracking and other phenomena, check whether the triangle belt is tightened, whether there is cracking sieve box, sieve plate is not damaged, check whether the sieve plate has debris blocking screen surface to be flat. No damage, loosening phenomenon, check whether the chute in and out of the material is dredged, check whether the cross beam is welded or not, check whether the safety protection device is safe and reliable, check whether the control box, communication, lighting is not missing, whether the grounding maintenance is reliable, whether the control button is flexible and reliable.


High Speed Mixer

When the high-speed mixer starts: after opening the sieve, stand by the control box to monitor the start of the equipment and stop immediately when abnormal start is found. The nozzles of each oscillating screen are checked again after starting up normally. The temperature and sound of the motor are often investigated. The sound of the exciter is often investigated. The quadrangular amplitude of the oscillation of the screen is also investigated. Whether the triangular belt of coal leakage is loose or falling together or not, and the dehydration and decoupling effect is often investigated. Check whether the sieve is in and out of normal condition or not.


High-speed mixer shutdown: After the material on the screen is discharged, the machine can shut down. When parking, it is necessary to investigate whether the sieve collides with other equipment when passing through the resonance point. When the following conditions are found, it is necessary to stop immediately. In case of endangering personal safety or equipment safety, when there are more debris in the screen area and the blanking is not smooth, the screen mesh is broken in a large area, the chute under the screen is blocked seriously, and the screen box is seriously swaying, and other abnormal conditions. The operation of the oscillating screen can be restarted after the problem is cleared.
