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.
An intermediate partition, called the central diaphragm, separates the coarse and fine grinding chambers. The purpose of the central diaphragm is to retain the grinding media in their respective chambers, provide adequate opening for the airflow and, in some special types, regulate the feed to the second compartment.

Cement grinding with our highly efficient ball mill An inefficient ball mill is a major expense and could even cost you product quality. The best ball mills enable you to achieve the desired fineness quickly and efficiently, with minimum energy expenditure and low maintenance.
Diaphragms for ball mills, Level Control Diaphragms HARDER WEARING, COST-EFFICIENT DIAPHRAGMS FOR CEMENT MANUFACTURE Improved grinding media and liners can do much for productivity but the benefits can be reduced without equally efficient diaphragms.
These models can be used to simulate cement grinding circuits and to assist their optimisation. The "work horse" of the cement grinding plant is the two-compartment ball mill, commonly called the tube mill. Significant advances in model development were achieved in recent years (Benzer et al, 2001, 2003) through research on industrial scale.
Coal Grinding Mill. Our coal grinding mills are used in coal powder production lines with an output range of 8-83t/d. We have decades of experience in the production of coal mills that are designed to handle a wide variety of bituminous coal and anthracite with a maximum capacity of 85 T/h. The main components of this coal grinding mill are ...
Closed circuit ball mill with two compartments for coarse and fine grinding are generally found in cement plants for cement grinding. Compartments (filled with grinding media) are divided by a double diaphragm with flow control to utilize maximum mill length for effective grinding.
Two-compart- ment separator mill for cement The mill shell is divided by a diaphragm. Coarse grinding using big balls of up to 100 mm in diameter takes place in the first com- partment. The peripheral wear lining is designed as a lifting or activator plate lining which, with the large balls, achieves a high energy input for comminution.

High pressure grinding rolls (roller presses) are used in both cement raw materials (limestone, clay, shale etc.) and cement grinding stages. The energy consumption is 2.5–3.5 kW h/t and about 10 kW h/t when recycling of the material is used.A HPGR consumes 30–50% less specific energy as compared to a ball mill which indicates higher comminution efficiency for a HPGR.
