A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. It's mainly used in grinding raw materials and end products in cement plant. Raw mill is made up of feeder part ,discharging part ,rotating part ,transmission part(reducer,samll transmission gear ,motor,electric control) etc.
Raw mill is also called raw material mill, which is the essential equipment in the production process of cement. It has large application such as raw mill in cement plant, building materials, metallurgy, electric power and chemical industry, which is mainly used for the grinding as well as drying of cement raw materials and other materials.
About 85% of the total energy expended in cement production is used for size reduction; 75 % in grinding operation alone and 2 20 % of the energy supplied to the mill is used for size reduction, the remaining is lost in various activities such as friction between particles, friction between particles and mill elements, generation of heat and sound, vibration and material turbulence etc.
Raw material vertical mill_cement production process. Application: Cement electric power metallurgy chemical industry and etc. Raw material vertica l mill is an advanced grinding equipment designed and developed on the basis of extensive use of advanced technology at home and abroad combined with many years of experience in the production of vertical grinders.
The raw materials of Cement Mill Process are lime and silica. Alumina and ferric oxide are used as fluxing agents. Collection of raw materials such as lime stone. This is transported to the mill site and crushed there if the quarry is far off. If the quarry is nearer it is crushed at the quarry itself and transported to the mill site. Grinding
cement industry the ball mill was really an epoch-making breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal, and still today is the most used mill for cement grinding. Over the last three decades the vertical roller mill has become the preferred mill for grinding of raw materials.
The raw mix is fed into a circular storage unit called a raw mix storage. Then, the mix is extracted transversely from the stockpile by reclaimers and conveyed to a raw mill bin called the raw mix bin for grinding. The other raw materials that are used in cement manufacturing, called additives, are high purity limestone, sand and iron ore.
Jan 07, 2015· Raw mills usually operate at 72-74% critical speed and cement mills at 74-76%. 3.2 Calculation of the Critical Mill Speed: G: weight of a grinding ball in kg. w: Angular velocity of the mill tube in radial/second. w = 2*3.14*(n/60) Di: inside mill diameter in meter (effective mill diameter). n: Revolution per minute in rpm. 7.
