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 Esong 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.

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.

The mining sand crushing machine is the crushing machine that has the widest application in the crushing stone and sand aggregate in the basis construction. Concrete is the most important building materials so that the quality of the sand and stone aggregate. The artificial one is the most advanced crushing equipment in the crushing technology field. In order to guarantee the quality of these materials, adopting the technology of screening and washing and ore dressing will improve the quality of them and improve the economic benefits of the crushing and grinding machines.
