Cement Mill

What is Cement Mill?

Also called cement ball mill, cement mill is the key equipment that grinds the crushed materials. The cement ball mill produced by Fote adopts high chromium alloy steel or double medium quenched steel liner, which has the characteristics of high quenching hardness and high toughness. The wear in production is small. The milling form of open flow provides a strong guarantee for the production of high-quality materials. According to different needs, FTM cement mill adopts two transmission forms including brim type and central shaft type, which is of flexible configuration.

Applications of Cement Mill

Cement mill kiln is mainly used for calcining cement clinker, which is divided into two categories: dry cement mill kiln and wet cement mill kiln. Besides, it can be used for glass, iron ore, gold ore and other materials in silicate products, new building materials, refractory materials, chemical fertilizer, black and non-ferrous metal processing industry and glass ceramics industry.

Application of Cement Mill

How Cement Mill Works?

First of all, the material is fed into the first silo of the mill evenly through the feeding hollow shaft spiral. There are ladder liner or corrugated liner in the bin, and steel balls of different specifications are inside. The rotating of the cylinder produces centrifugal force to bring the steel ball to a certain height and falls down, which has a heavy impact and grinding effect on the material. After the rough grinding in the first silo, material enters the second silo through a single layer partition board. In the second silo, there is inlaid with a flat liner and a steel ball. Here the material is further ground. The powder is discharged through the discharge grate plate to complete the grinding operation.

Working Principle of Cement Mill

Structural Benefits of Cement Mill

• The cement ball mill adopts high chromium alloy steel or double medium quenched steel liner, which has the characteristics of high quenching hardness and high toughness. This arrangement reduces the wear in production. The liner can maintain the surface shape for a long time and completely eliminate the powder leakage. The maintenance is reduced by over 98%, the output is increased by more than 5%, and the power consumption is reduced by more than 5%. 
• By thickening the diameter of the hollow shaft in the rolling bearing part of the cement ball mill, the radial distance between the rolling bearing and the inlet and outlet spiral cylinder is increased, which plays a certain role in heat insulation and cooling, and prolongs the service life of the bearing. 
• The self-aligning spindle is adopted to ensure a normal operation of the rotating part. The good lubrication of cement grinding can be guaranteed by using the lubrication mode of oil spoon, oil ring and automatic oil filling station.

Cement Ball Mill Maintenance

>>How to Judge the Feeding is Insufficient?

1. Grinding sound is higher than usual; The mill current increases; The current of bucket elevator drops; Negative pressure of mill gas drops;The current flow of powder dressing machine drops. 

Adjustment: slowly increase the feeding capacity of the mill; if it doesn't work after a period of operation, increase the output of roller press; stabilize the new feed quantity after each parameter is displayed normally.

>>How to Judge the Blockage of the First Silo?

1. The grinding sound decreases; The bucket elevator current drops; The grinding gas negative pressure rises; The grinding sound of second silo is rather loud, while the first is very low;The powder separator current drop

Adjustment: reduce or stop the feeding system; increase the mill ventilation volume; when the two methods fail, stop grinding and have a check.

Classic Case of Fote Cement Mill

In Zambia, FTM cement grinding mill is used for clinker with a capacity of 50TPH.
