How to Settle Complete Grinding of Ball Mill?

Ball Mill is widely used in metallurgy,build material,coal,chemical,pottery and curative industry,and it is one of the most important equipments.this kind machine is main made up of one big shell,bearing and gear.There are many grinding medium,such as steel ball.

It is a dangerous signal of the full grinding phenomenon of ball mill - a commonly used dressing machinery. The full grinding phenomenon is also known as 'full mill' or 'boring mill', which belongs one of the common anomaly phenomenon in the operation process of ball mill. Therefore the operator should timely deal with the problem if the situation happens. Specialists from hongxing machinery will teach you how to solve 'full grinding' phenomenon and the details are as follows.

First of all, the sign of 'full grinding': if it is a slight full grinding of the ball mill: the mill sound will gradually become low from clear, the discharging amount of the mill tailing is reduced and the pressure at the import and export port of the ball mill increases; if the full grinding of the ball mill is serious: the grinding sound will disappear, the current of main motor is reduced considerably, and the discharging amount of the mill tailing reduces greatly. Now we will detailedly introduce the good solutions of the' full grinding' phenomenon of ball mill:

1. It is generally reduced the feeding or stopped the feeding and strengthen the ventilation of the ball mill so that the ball mill operating with less material or no material to produce more heat. As with the drying mill, it should be increased the feeding heat of the mill, which is in order to make water quickly evaporate and take hot air away at the same time; at the same time, the adhesion material adhered on the steel lining plate and the partition plate and in grate gap will be dropped off for thermal expansion. To a service-oriented brand integrity,As the professional manufacturer of complete sets of mining machinery ,like sand washer, Henan Hongxing is always doing the best in products and service.

2. If the method described above is invalid, stop the feeding and add auxiliary agents for ball-milling to the ball mill (such as add coal or lime to the raw mill, and add dry slag or dry slag to cement mill), then feed small amounts of material after the grinding sound be closer to normal; after the grinding sound normal you can gradually increase the feeding rate until normal feeding.

3. If the 'full grinding phenomenon' is particularly serious, it needs use the inverted grinding method, which is pouring the ball and materials in the chamber and completely pitched the crust on the lining plate and the steel ball, clear the clogging objects of the bin isolation board slot, and then re-equipped the ball or replace the poured ball. Which is suitable for the clearance of the wet ball mill.

After the separating warehouse, the ball mill can be saving ball mill consumable, such as steel ball and lining board consumption.In addition, after the classified chamber the ball mill can play two different effect, one is crushing, the other is the grinding effect. It uses the inertial force of large equipment for crushing, which is the unique property of the classified chamber ball mill.
