Of course, even if we set a more appropriate cement fineness, it is difficult to change the current situation that the flow velocity in the open-circuit ball mill is only 1/2-1/3 of that in the closed-circuit ball mill with the same …
additive) are proportioned and ground in Cement mill (one Closed circuit ball mill in line 1 and two Roller press+closed circuit ball mill in line 2) based on the type of cement to be produced keeping the quality of cement equal or above the required standard. For instance (Clinker+Pozzolana+Gypsum) are proportioned and milled
The request for interchangeable parts for the three mills was fulfilled and represents still a holistic approach. For coal grinding a QMK² 32/16 completed the grinding portfolio. The cement mills are equipped with high efficiency separators to achieve cement qualities with a fineness up to 5 000 cm2/g acc. to Blaine.
The design capacity of the mill is 120t/h for OPC cement. But currently it is working upto 120-135t/h for OPC and 135- 150 t/h on PPC. Specific surface of the product is ... The separator will classify the ground material into two parts – the course and the fine (product).The coarse material is fed back to the tube mill via the air slides ...

After cooling, the clinker may be stored temporarily in a clinker store, or it may pass directly to the cement mill. The cement mill grinds the clinker to a fine powder. A small amount of gypsum - a form of calcium sulfate - is normally ground up with the clinker. The gypsum controls the setting properties of the cement when water is added.
The vertical cement mill is large-scale cement grinding machine. With advantages of energy-efficient and stable quality, vertical roller mill is widely applied to many industries, such as cement, power, metallurgy, chemical and nonmetallic mining industry and etc. As a typical type of Cement Mill, vertical cement mill set crushing, drying, grinding, grading …
Although motors may appear to be the least complicated component in the specification of cement mill equipment, this article shall try to demonstrate that cement plant applications present an immense matrix of application criteria to properly specify and design motors. To obtain the correct motor for the specific job, communication, …
Clinker grinding technology is the most energy-intensive process in cement manufacturing. Traditionally, it was treated as "low on technology" and "high on energy" as grinding circuits use more than 60 per cent of total energy consumed and account for most of the manufacturing cost. Since the increasing energy cost started burning the benefits …
