How does sand made into finished product cement

In the whole , drying and grinding operation are the most important process.
The main drying equipment used in cement production is dryer. We will not introduce it at length. Details please click: dryer.
I would like to introduce you the main process, grinding. The main equipment used in this process is cement ball mill, for short is cement mill. Cement milling products are mainly used for grinding of cement finished products and raw materials, it is also used in mining enterprises and grinding ore material in metallurgy, chemical industry, electric power and other industrial. Cement mill can be used for open-circuit grinding, but also applies to circular ring flow being composed of the powder grinding machine. Cement mill is distinctive for strong material adaptability, being able to continuous production, big crushing ratio, easy to adjust the speed of the grinding fineness and so on. It is available to both drying and wet production, which can also be done with drying and grinding operations at the same time. After drying process, raw materials, treated by cement mill and become cement raw material. And then one of the key cement machinery products is to be used: cement rotary kilns. As we all know, after the cement grinding, the cement is raw, that is, after mixing with water, cement is cement, and water is still water. We cannot mix the two together, so we will treat raw cement with cement to get the cement of semi-finished products.
Why did we say it semi-finished products? That is because there are not 100% of the raw materials grinded into powder. We will screen and select the semi-finished cement that just out of rotary kiln. The materials not grinding into powder will be sent back to production line for grinding.
Hereto, cement production comes to an end. Without doubt, the conveyor is necessary in the whole production line. Conveyor is used everywhere when raw material entering into dryer, from dryer entering into cement mill, and entering into cement rotary kiln after out of cement mill.
Cement rotary kilns are a kind of building material machines. According to the difference of processed material, rotary kilns can be classified into cement rotary kilns , metallurgy chemical rotary kilns and lime rotary kiln.
Recently, the cement rotary kilns are most often used to dispose of waste. In rotary kilns, waste is burnt and disposed of, which has made much success around the world. This way is very good because it is economical, harmless and can prevent from secondary pollution.
