The way solving full mill helps mill users much

Cement mill "full mill" means the tube mill feeding and the discharging materials are out of balance. It is caused by the oversupply materials in cement in a short period of time. The reasons are different: cement mill feeds too much, or because grinding capacity is inadequate.

In mining machinery, we usually set up a tertairy crushing machine before ball mill to reduce particle size. Hand over primary crushing task from the original mill coarse grinding cabin to efficient fine crusher, which is the so-called "multi-break less grinding". In closed system, due to ore concentratrator efficiency has reduced too large, feedback materials is too much without the feeding materials reducing, the powder grinding capacity of cement mill can not support it. Now let us learn together about the Raymond mill operation. For the clearance of the cement mill, down mill approach is available. As account of the feeding materials is high material moisture content, and take the air bad, the wind can not take away the water vapor and fine material generated in the grinding process timely and bring them out of the cement mill. As a result, due to humidity, the material adhesion at the steel ball and liner surface, thus increased the cushioning effect and reduced the grinding efficiency; At the same time, wet material obstructes the gap of the cement mill diaphragm plate and a discharge sheet, bringing about discharging problems.
The role of the energy-saving ball mill liner is protecting the whole mill body and affecting the grinding efficiency. There are deposited liner at ball mill cylinder, end caps and hollow journal. Apart from protecting cylinder, the cylinder liner affects the ore media sports regular pattern and grinding efficiency. When the liner is smoother, it is less to enhance the role of the grinding media and the impact is less important, while abrasive is stronger. The liner also requires wear resistance. Due to the impact of media and slurry, grinding and erosion-corrosion make the wear of the liner. In addition to material quality and shape of the liner, the wearness is also related with feeding ore material size, ore grindability, steel ball size, tube diameter, ball mill speed and slurry corrosive factors and so forth.

Demestic energy-saving ball mill liner is made from alloy steel and gradually replacing high-manganese steel liner. With the constant application in the ball mill liner, the alloy steel liner has been gradually developing into the mainstream of the market development.
