A ball mill is used to grind solid materials into powders. It's commonly used to make paints and ceramics. It rotates on a horizontal axis and uses iron or stainless steel balls to crush materials into powder. With a container and a power drill, you can quickly make your own ball mill.
first，Installation Ball Mill
The quality of ball mill installation quality, the ability of mill is the key to normal work. Various types of ball mill installation method and sequence similar. To ensure the smooth functioning of ball mill and reducing the harm to the buildings, it must be installed in its weight of 2.5 to 3 times the reinforced concrete foundation.
Installation ball mill, the first should be installed main bearing. In order to avoid aggravating the problem of the hollow crankshaft bearings lining and shoulder wear, the two main bearing the base plate of elevation difference in the length of each meter should not more than 0.25 mm. Secondly, the installation of the ball mill cylinder of the light of the specific conditions, can be pre-assembled the entire English Department loaded directly, but also can be divided into several parts of the installation, adjustment and should check with the centerline Journal and the ball mill, the error must ensure that its Concentric within per meter in length should be less than 0.25 mm. The final installation of the transmission components (small gear, uranium, coupling, reducer, motor, etc.) During installation, product technical standards should be measured and adjusted. Gear check the radial pendulum poor and small gear meshing performance; gear reducer and small concentric degrees, and the motor and reducer concentric degrees. When fully installed are in line with requests, we can not go on the basis of bolt main bearing floor and the last watering.
Second, Operation and maintenance of ball mill
If the ball machine running high rate of grinding effect, and to strictly abide by the operation and maintenance of order. Starting in the ball mill, should check whether the tightening bolt connections; gears, coupling, etc., as well as the keys to the first mine-spoon Solid tight situation.
Check the oil tank reducer and the adequacy of the lubricating device and instrumentation whether illnesses, pipes unimpeded. Check ball mill with classifier equipment availability impede functioning of the surrounding debris, and then use the cable car to the ball mill-week, the ball loose tube Dutch and ores, and to inspect the ring gear and pinion meshing, there abnormal sounds. The start order is first activated ball mill lubricants pump, when the hydraulic reach 1.5 to 2.0 kg / cm 2 o'clock, the ball mill will be allowed start again start classifier. Everything is running normally, and so on, can begin to draw mine. In operation process, should always pay attention to bearing temperature should not exceed 50 ~ 65 ° C. The attention to the regular motor, voltage, current, temperature, audio, and so on. Attention lubrication system at any time, the oil tank should not exceed 35 ~ 40 ° c, to tubing pressure should be maintained at 1.5 to 2.0 kg / cm 2. Check size gear, the main bearings, such as grading machine transmission components reducer lubrication, and attention to the observation before and after the ball mill Cover, Simplified and exclusive ore bins overflow tank and machine classification back to the trough of sand plug the leak and sand. Regular attention to the changing nature of ore, according to the situation promptly and take appropriate measures.
Stop ball mill, the first stop to the mining machine, within the ore processing to be simplified after the end of ball mill motor to stop, the last stop pumps. With the upgrade installations classifier to the spiral of sand, and then stop classifier.
