In theory a mill that's completely plugged such that grinding media cannot tumble will produce no noise at all. Some plants report this value as decibels. Other reverse the signal and express it as % level or % full. In general, mill sound is useful in determining whether a given compartment is plugged or plugging or to show that the compartment is emptying. with each compartment equipped

Jul 31, 2021The size reduction takes place in a two- compartment tube mill; the first compartment of the mill is shorter than the second compartment. The coarse clinker is ground in the first compartment where larger balls (80, 60, 50 mm) are used and the fine grinding is done in the second compartment where smaller balls (below 25 mm) are used.
Ball mill is a cylinder rotating at about 70-80% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills. Grinding media consists balls of 3-4 sizes (60mm-30mm) in designed proportions with large sizes in feed end and small sizes in discharge end.
For mills with integrated drying chamber. By means of the open lifter diaphragm, the drying chamber integrated into the mill tube is separated from the grinding compartment. The steel grades used can easily withstand the up to 400C hot gases found in the drying compartment.
Note: Down side line for the grinding media40mm and the upper one for the grinding media40mm. Example: Two compartment cement mill Diameter = 4.05 m Length = 12 m Filling degree = 196 tons at 30% filling degree Mill speed = 16.27 rpm C = 0.223 (from the figure) Then: K = 0.223 * 196 * 4.05 * 16.27 = 2.88 KW
Ball mills of greater length are termed "tube mills," and when hard pebbles rather than steel balls are used for the grinding media, the mills are known as "pebble mills.'' In general, ball mills can be operated either wet or dry and are capable of producing products on the order of 100 um. This duty represents reduction ratios as

22.214.171.124 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

Based on a population balance principle and stochastic representation of the particle movement within the grinding system, the Markov chain model for the circuit consisting of a tube ball mill and a high efficiency separator was introduced through the matrices of grinding and classification.
mill, etc). 2. Grinding media The grinding media used are, generally, balls and cylpebs. In compartments of coarse and medium grinding are used balls, and in that of fine grinding, balls or cylpebs. In any compartment, sizes of grinding media must be correlated with the size of the material. Between the balls are formed free spaces (emptiness).
