Fans in cement industry are heavy duty and perform two basic functions i.e., supply of air or removal of exhaust gases and material handling. There are many process fans that find applications in cement industry such as raw mill fans, induced draft fans, cooling fans, raw mill exhaust fans, coal mill fans and cooler exhaust fans.
Jun 25, 2013· It may be related to clinker chemistry, kiln operation, clinker cooling, finish mill operation, use of a secondary clinker source, sulfate content, or a completely different cement source. Many things can change with fineness.
Aug 30, 2012· Cooling and Final Grinding; Packing & Shipping; Cement Manufacturing Process Phase 1: Raw Material Extraction. Cement uses raw materials that cover calcium, silicon, iron and aluminum. Such raw materials are limestone, clay and sand. Limestone is for calcium. It is combined with much smaller proportions of sand and clay.
Cooling classes:IC 01, IC 06, I C 411, IC 416, IC 611, IC 616, IC 666, IC 81W, IC 86W, IC 511; Electric motors for cement plants - fast and individual. A costly industrial plant such as a cement mill must produce flawlessly at all times.
Fig. 3. cement mill section in dry process It is important to note that the strength properties of cement are considerably influenced by the cooling rate of the clinker. The rate of cooling influences the degree of crystallization, the size of the crystal and the number of amorphous materials present in the clinker.
In addition, the bearings used in the cement mill are generally equipped with cooling water channels to ensure good working conditions of the bearings. Advantages of cement mill performance Cement mill advantages 1 Fote cement mill adopts a conical grinding roller and flat grinding disc. The structure is simple and reasonable, and the service ...

Ball Mill Noise Control in Cement Grinding Process. Ball mill is a kind of grinding equipment in mining field and cement plant.It can grind hard stones and materials not greater than 320 MPa, such as mineral powder production lines, cement production lines and other grinding equipment suppor...
The cooling of cement is an important step prior to storage in mitigating gypsum dehydration and subsequent moisture liberation which can lead to lump formation. Recommendations vary but it is generally accepted that with mill outlet temperatures of around 110ºC – 120ºC, cooling to below 80ºC is necessary to avoid this reaction.
