Experts said that the Chinese cement industry is developing rapidly, but also suffering from the trouble of overcapacity and declining profits. The industrial restructuring has become a top priority. Experience has shown that industrial chain extending to the upper reaches of the mine sand and gravel and other raw materials industries, downstream concrete industry can reduce the operational risks, reduce marketing costs, and extend the value chain, to support the development of the main industry. A growing number of cement companies began to focus on concrete and mining sand and gravel industry, the establishment of new cement production line at the same time concrete mixing station, the control of the downstream market, and lay the foundation for the sustainable development of enterprises.
Why do we call them semi-finished cement? Because the cement processed by cement mill can’t reach100% of powder raw material. So we should screen the semi-finished cement by using rotary kiln， and re-process the raw materials which are not powder.
Thus， the cement production process is running to the end. Of course， the conveyor is indispensable in the whole production line. Whether in the process of raw material into the dryer or the dried product into the cement mill， and even the product after milled in to the rotary kiln， all of the steps are integrated by the conveyor.
The layout of the cement production line is set up cement clinker production line in mining area， and builds cement grinding station near the cement sales market in the big and middle city. Most of the cement admixture is the city’s industrial waste generated. Crushed large materials is in mechanical forces to the smaller size processBall mills. Crushing is an important link of the mineral processing. Crushing can be divided into four stages: crushing, grinding, superfine crushingStone crusher, superfine grinding. Crushing process is high energy consumption of homeworkRock crushing plant, crushing the basic principles of the process is "much more broken little ground".
Cement grinding station can greatly absorb the slag，Flotation machine fly ash， cinder， coal gangue and other industrial waste，Cement production line which is a green industry. The cement station provided by our country adopts the simplest process flow， with the advantages of easy to operation， at least process equipment， low investment， energy-saving and environmental protection; what’s more it can be mixed with more materials.

In the cement production process， drying and milling are the two most important steps.
