The Key is to Improve the Outout of Cement Mill


Cement clinker mill could be the main equipment in cement  mill or cement clinker processing plants in cement market. In cement quarries, you’ll be able to see cement clinker mill operating with cement clinker crusher as well as other cement mill  for cement production lines.
The chief constituent of Portland cement is a sintering product of limestone and aluminosilicate known as clinker. This hard, pebble like material is the ingredient in cement which causes it to “cure” and harden to form the mortar or concrete used so extensively in construction. The clinker sintering or heat combination process produces a coarse, nodular material of particular hardness which requires fine grinding prior to cement production. Particle sizes of below 45 µm are required which, due to clinker's hardness, requires a particularly efficient milling process. Although there are several mill types capable of grinding clinker, the most commonly used cement mill process is the ball grinder.
How to improve the output of cement mill is very important for improving the working efficiency of cement production line and also is the problem that everybody cares most. Henan Hongxing has spend much time and energy on improving the yield of cement mill. The following six measures improving the yield of cement mill is summarized by Henan Hongxing according to its rich experience. Then we will give the details of the six measures.
One, control the grind-ability of the feeding material to ensure the feeding grinding material with high grind-ability and the feeding material should be the fine mixed material with good activity and grind-ability. To a service-oriented brand integrity,As the professional manufacturer of complete sets of mining machinery ,like rotary dryers, Henan Hongxing is always doing the best in products and service.
Two, should strictly control of the grain size. To control the grain size you can use the method of 'more crushing and less grinding' to keep the grain size under the internal control standard. Besides, you can also control or tracking adjust the grain size of fine mixed material to accomplish the truly reasonable feeding of various materials.
Three, control the The control the moisture and temperature of the feeding material and the moisture content of mixed material into the plant should be strictly controlled and carefully examined, and strictly control the temperature of grinding material within the process requirement.
Four, control the fineness of finished products, the controlled methods mainly include screen method and cement specific surface area method. The 0.08mm screen margin should be controlled in the range of 2.5% ~ 3% and cement specific surface area should be controlled in the range of 360 ~ 375m2/ kg.
Five, control the ventilation of the cement mill to ensure the good ventilation inner the mill, in normal production circumstances, all the ventilation pipeline should be cleaned regularly.
According towards the cement clinker grinding procedure, Hongxing, as a professional cement clinker mill manufacturer, can supply you cement ball clinker mill, Raymond cement clinker mill, vertical cement clinker mill, trapezium cement clinker mill and so on.
