Cement Mill

The Introduction of Cement Mill:

Cement mill is the equipment used to grind the clinker and raw materials from the cement kiln into the fine grey powder that is cement.The mill also can be applied in metallurgy, chemical, electric power and other industries to grind all kinds of ores.Most cement is currently ground in ball mills.Cement mill is normally driven by electric motors.The output achieved by a cement mill system varies with the mill power, the fineness of the product and the hardness of the clinker.

In the technics of Cement production process, People usually choose limestones and clays as the main raw materials, crushing, concocting, grinding them into cement raw meal, feeding them into cement kiln,Cement clinker is usually ground using a ball mill.After being calcined maturity, adding appropriate amount of gypsum (sometimes mixing the mixed material or admixture) then being grinded, and the cements form.
1.crushing and pre-homogenization
2. The prepare and homogenization of cement raw meals
3.pre-decomposition and the burning of cement clinker
4. cement grinding

Kefan Machine not only have skilled technicians and experienced service team, we also apply Internet technology into all aspects of production and management process which can provide timely provision of the latest products' information and technical services. We provide the best warranty and extended warranty plan for our products. The cement manufacturing process consists of many simultaneous and continuous operations using some of the largest moving machinery in manufacturing.

Introduction of Rotary Kiln :<a href="http://www.cement-equipment-kf.com" title="Rotary kiln"> Rotary kiln </a>is the main equipment of calcining cement clinker.The drying machines are used to heat solids to the point where a required chemical reaction(s) takes place. The <a href="http://www.cement-equipment-kf.com" title="Rotary kiln"> Rotary kiln </a> is basically a rotating inclined cylinder. Solids retention time in the kiln is an important design factor and is set by proper selection of the diameter, length, speed, slope and internals design. There are two basic types of rotary kilns; direct fired and indirect fired.The dryer is used in the cement plant to calcine high grade cement, at the same time can be used in metallurgy,chemical,construction ect.Our <a href="http://www.cement-equipment-kf.com" title="Rotary kiln"> Rotary kiln </a> system is after technology innovation, being used in the most advanced hydraulic gear wheel device, the metering piston pump of high precision, the high precision control valve and contact graphite blocksealing devices and other advanced technologies. It features in easy to operate and operational safety. Compared with the same specification equipment, the rotary kiln stabilizes the thermal system program and improves the equipment operation rate, with the operation rate increased by 10%, the yield increased by 5% -10% and heat consumption reduced by 15%.Kefan designs and supplies both direct fired and indirect fired rotary kilns for a wide variety of applications. We have supplied over a thousand rotary kilns ranging in size up to 7.6 meters in diameter and 190 meters in length.Therefore, we can provide repair parts to the original tolerances and specifications and take advantage of the latest designs and improvements.
