For the new installation or overhaul of the ball mill, put into production before the test should be carried out. Ball mill test is divided into three stages:
(1) Preparation before commissioning. Mainly check the motor and electrical, ministries of the Ministry of fastening screws; check lubrication, sealing and other measures are intact, and for turning; check whether there are anomalies.
(2) the no-load test, by barring no abnormal phenomenon, can be empty (no medium and material) and start the 8~16h should meet the following requirements: normal continuous operation of lubrication oil; ball mill main bearing temperature not exceeding 50 degrees; the operation is stable without abnormal sound; each component loosening.
(3) load test, in two stages.
1) half load test: medium filling rate of phi = 25%~30%, give the appropriate amount of material and water (not running 8~10h.)
2) full load test: in the half load test run after all normal, the medium added, the appropriate increase in the amount of mine, full load running 10~20h, and finally should meet the following requirements: The operation is stable without abnormal sound; the main motor current fluctuations within the allowable range; the temperature in the allowable temperature rise below; the normal lubrication of main bearing; temperature not exceeding 60 degrees; the no leakage of mine, Water Leakage, the phenomenon of oil leakage. The no-load test is not installed medium (ball, rod) and the material under the condition of idling. Continuous operation should not be less than 4h, generally running 8 ~ 16h, can be determined according to the specific conditions. The test time is longer, the main bearing, gear tooth surface of research better.
1) the lubrication point of the normal, there is no oil leakage phenomenon.
2) the main bearing of ball mill temperature should not exceed 50 degrees Celsius. Price specifications... To explain the working principle of equipment and features, to provide reference and recommendations to buy crusher products for users. The following is the ball mill no-load and load commissioning requirements is what? Is not installed in the no-load test medium (ball and stick) and material under the condition of idling. Continuous operation should not be less than 4h, generally running 8 ~ 16h, can be determined according to the specific conditions. The test time is longer, the main bearing, gear tooth surface of research better.
No commissioning test shall meet the following requirements:
1) the lubrication point of the normal, there is no oil leakage phenomenon.
2) the temperature of the main bearing of the ball mill should not exceed 50 degrees Celsius.
3) the operation of the ball mill is stable, and there is no abnormal noise in the gear transmission.
4) the lining board and the transmission parts are not loose.
5) each operation in accordance with the maintenance requirements.
The sky turned to reach the required time, stop the mill operation, carefully check all parts, tighten the liner bolts, eliminate the defects found. After the no-load test after passing the test. It can make the load load test to gradually feed until full load. In the normal feeding after operation 10 ~ 20h.
Load operation should meet the following requirements:
1) work smoothly and without periodic sharp vibration.
2) the current of the main motor has no abnormal fluctuation.
3 lubrication point lubrication is normal, the main bearing temperature is not more than 60 degrees Celsius.
4) the work part of the bolt, ball into the hole, the flange surface and the seal without Water Leakage, slurry leakage and other phenomena.
