Cement mill outline
Cement mill also named as ball mill, raw material mill, material grinding mill and clinker mill, is the key equipment for grinding after the crush process, which is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics, and can be used for the dry and wet grinding for all kinds of ores and other grind-able materials.
Structure of cement mill
Cement mill is composed of feeding part, discharging part, turning part and driving part (reducer, small driving gear, electric motor and electric control). The quill shaft adopts cast steel part and the liner is detachable. The turning gearwheel adopts casting hobbling process and the drum is equipped with wear-resistant liner, which has good wear-resistance. The machine is with stable and reliable working condition. Moreover, according to different materials and discharging methods, there are dry ball mills and wet ball mills for choice.Capacity of cement mills
The cement mills on a cement plant are usually sized for clinker consumption considerably greater than the output of the plant's kilns. This is for two reasons:
The mills are sized to cope with peaks in market demand for cement. In temperate countries, the summer demand for cement is usually much higher than that in winter. Excess clinker produced in winter goes into storage in readiness for summer demand peaks. For this reason, plants with highly seasonal demand usually have very large clinker stores.
Cement milling is the largest user of electric power on a cement plant, and because they can easily be started and stopped, it often pays to operate cement mills only during "off-peak" periods when cheaper power is available. This is also favourable for electricity producers, who can negotiate power prices with major users in order to balance their generating capacity over 24 hours. More sophisticated arrangements such as "power shedding" are often employed. This consists of the cement manufacturer shutting down the plant at short notice when the power supplier expects a critical demand peak, in return for favourable prices. Clearly, plenty of excess cement milling capacity is needed in order to "catch up" after such interruptions.

Cement grinding station advantages
Cement production in the mining area to establish the layout of cement clinker production line, in the major cities in the vicinity of cement sales market is set up near the cement grinding stations. Admixture produced most of the urban industrial waste, cement grinding stations around the city greatly digest of slag, fly ash, slag, coal and other industrial waste, is a green industry to provide the cement grinding factory Point process used in the most simple and most convenient operation, process equipment, at least, less investment, saving, environmental protection, hybrid materials can be mixed with more advantages.
