How to install ball mill ?
Ball mill is an efficient machine for powder grinding. It is widely used for the cement, the silicate product, new type building material, fire-proof material, chemical fertilizer, black and non-ferrous metal, glass, ceramics and etc. Ball mills have two ways of grinding: the dry way and the wet way. It can be divided into tabular type and flowing type according to different extracting way of mine. So how to install ball mill? Experts from Liming Heavy Industry give the following tips:
1. The operation of the air at least 12-24 hours of continuous operation time, operation found that the problem should be solved.
2. Air test machine can be normal load test run. Load test run should be carried out in stages. Load operation should be conducted as nesting feeding, to avoid unnecessary ball and cylinder liner wear loss and damage.
3. An increase in the loading and commissioning of the length of time, the size of gears and gear to the running-gear case (temperature, noise, tooth contact, etc.) as a basis for determining. Accuracy of the tooth contact does not meet the design requirements, it shall not at full capacity.
4. The commissioning of cooling and lubrication system should be working properly. Main bearing, transmission bearing, reducer temperature should be normal.
5. When ball mill body was adjusted to be level, just then install the transaction parts. At first, check the quality condition of transaction parts, mainly check small gear shaft and reduction gear shaft is concentric or not.
6. Regard the big gear wheel as the basic, then install and adjust the transaction parts, make sure the tooth width of small gear and big gear are accordant. In addition, the tooth surface of small gear and big gear also should keep accordant, the least space of gear should leave 0.25mm. The contact surface of big gear and small gear accounts for 60% of the overall length and about 40% of overall height.
