The following attentions of single section crusher should be concerned during operation.
1. Inspection before machine start
a. Check the lubrication grease of main shaft bearing, feeding roller bearing and middle shaft bearing, check the oil charge of reducer;
b. Check whether there are any foreign matters inside crushing cavity;
c. Check whether the feeding roller collide with surrounding device;
d. Check whether the rotation direction of the output shaft in the feeding roller drive reducer is correct or not;
e. Check rotor turning, eliminate all the metal crash;
f. Check whether the bolts and anchor bolt are vibrating or not;
g. Check the motor rotation direction and whether all the doors are closed.
2. Machine running
a. No metal crash in the process of operation;
b. The rotor and feeding roller run smoothly;
c. The temperature of main shaft bearing should not exceed 80℃, the temperature of high speed shaft bearing not exceed 90℃, and the sliding bearing of feeding roller not exceed 65℃
d. The main motor with smooth current;
e. After stopping the machine, check the bolts and connecting pin in each component, and tightening the loose bolt and connecting pin.
3. Repair and maintenance
a. After the machine starting three minutes without abnormal condition, feed the materials. When stop the machine, must confirm there are no remaining ores left inside the crushing cavity.
b. The big ore are not allowed to put into the feeding roller.
c. The main shaft bearing (rotor bearing) and high speed shaft bearing (belt pulley bearing) must use lubrication grease, and should be replaced regularly.
d. The transmission parts like crusher's belt pulley and the V-belt should be covered with protection cover.
