How to extend the service life of ball mill

The ball mill is a key equipment to grind the crushed materials, and the ball mill is widely used in powder-making production line including cement, silicate, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc, and the ball mill can grind various ores and other materials with dry type and wet type. The ball mill users all know that they should take good care of ball mill in order to extend its service life. In order to extend the service life of ball mill, experts of Liming Heavy Industry gave following suggestions:

1. Ball mill often stuffy car phenomenon, occurrence of nausea cars, should stop immediately, it does not burn the motor. Then open the motor Fengye shell and mill peephole cover, closing the butterfly valve, dynamic disk motor Fengye, clearance of ball mill shell material, the hard foreign body or wrapped around the braided fabric cleaning clean.

2. The next is that during the use process , we should pay attention to several points: First, how to determine the speed of ball mill. Second, judge whether the ball mill is overload. Third, determine the ratio of steel balls.

3. Besides daily maintenance, it is still need regular maintenance every month. Liming Heavy Industry engineer suggest customers’ examine the hollow shaft , main bearing, barrel, reducer, gear, carefully and make detailed records. According to the defects, make proper repair and overhaul plan and arrangement.

4. Lubrication to make sure the ball mill to work normal:

When the ball mill is working, there are many parts touching with each other. To ensure the friction parts in lubrication is vital to the ball mill’s service life. Thus it will avoid the dry friction. It has been proved that the machine temperature will increase quickly in a short time; the heat will smelt the parts of the ball mill. Unfortunately, the machine will stocked even it can’t work anymore. Then we must guarantee the friction position have good lubrication. The oil flows to the frication part to cover the frication surface to enhance the movement of the machine. Oil plays an important role in the working process.

5. Other attention matters:

Besides the above mentioned there are also other factors need to be pay attention. First of all is how to determine the speed of ball mill; secondly estimate whether the ball mill is overload; thirdly, examine the steel ball ratio.
