Before Roll crusher taken into produce, it should be tested. The way of roll crusher commission as follow:
No-load running
1. Crusher must be started without loading , first check whether there is debris between the two roll gap and collision phenomenon. Turn the two rollers by hands for several rounds, if an exception occurs, handle it first before restarting.
2. Start no-load running when there is no abnormal with the machine. When you start at the first time, inch it and check whether the direction of rotation is right (based on the direction signs arrow on the machine). If there is no abnormal situation, we could start the normal no-load running.
3. The no-load operation must be more than two hours, then check::
A. When the host and the auxiliary machine start, if they have abnormal vibration and noise;
B. Whether the oil spills between the bearing and bearing cap
C. Whether the gear reducer leaks oil or has unusual noise;
D. Whether the motor is overheating or has unusual noise;
E. Universal couplings, cross slider couplings, pulley rotation should be stable, there should be no abnormal noise;
F. Observe the electrical control cabinet ammeter and voltmeter pointer fluctuations, when AC 380V voltage is stable, the current pointer’s fluctuation of the two motors should be very small;
Load Test Running
1. If the no-load operation has no problem, then can do load test running, the load test running should not be less than eight hours continuously;
2. Observe the actual consumption of motor power; whether it has abnormal temperature rise in load running;
3. After checking the machine and drive part, if situation is under normal condition then feed the materials, the first material should be 50% of the designed production, meanwhile adjust the current magnitude of feeder controller to ensure even feeding; adjust the gap between the charge distributor distributor panel, make it evenly feed the materials;
4. Observe movement amount of active roller bearing seat, if the moving amount is large, adjust the bolt which connects the spring;
5. If there is no abnormal condition after 2 hours, add to 80% of output materials, if there is still no abnormal condition after 2 hours, start the full load test running.
6. Stop the machine after full load running for four hours, check all parts of the machine and observe the discharge particle size and output amount, if everything is normal then it can be officially put into operation;
7. Measure the crushing particle size and output amount.
Any questions, even about failure, troubleshooting and maintenance, CONTRACT US, it is a pleasure to help you.
