Ball: The ball lies in cylinders, which are made up of stainless steel, the size of the ball depends on the cylinder diameter. The ball covers 30 to 50% area in the cylinder. Working: Open the lid and Feed the materials into the cylinder; Introduced the fixed numbers of balls and closed the lid
A ball mill consists of various components that work together to facilitate grinding operations. The key parts include the following: Mill Shell: The cylindrical shell provides a protective and structural enclosure for the mill. It is often made of steel and lined with wear-resistant materials to prolong its lifespan.
advantages over traditional ball milling in various applications. It is capable of handling a wide range of feed sizes typically from 400 to 90 microns. Support from Outotec experts Outotec draws from more than 100 years of mill design and manufacturing expertise, and over four decades of successful Vertimill® applications.
The ball charge tendency in the 1 st compartment is to use the coarser of the gradings available. When producing high Blaine Cement it is the objective to use less tonnage. Achieve nearer 8-9 kWh/t at the target mill output instead to go for a more fine ball charge. 3.2 Transition zone (2 nd compartment) CM and RM.
Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
Clinker, Gypsum and other desired additives are fed to the ball mill in specific proportions based on the quality requirement. Feed material is ground in the ball mill, discharged and fed to a classifier with the help of bucket elevator for classification of the ground cement into two a streams – coarse and fines.

The energy consumption of the total grinding plant can be reduced by 20–30 % for cement clinker and 30–40 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended. 2.5.

Q4: There are only rules of thumb for this: if you are doing coarse grinding, then you want a shorter mill; if you are doing fine grinding, then you want a longer mill. Eg. 200 µm product would be D:L of 1:1.5; 75 µm product would be a range between 1:1.8 and 1:2. Q5: Ball mill performance suffers with coarse feed, so keep the F80 below 5 mm ...

Grindability of a 95/5 OPC at various Blaine fineness: o 27-32 kWh/t at 3,000 cm²/g. o 39-47 kWh/t at 4,000 cm²/g. o 58-69 kWh/t at 5,000 cm²/g. Every 100 cm²/g increase in cement fineness increases the mill power consumption by 1-2 kWh/t for a closed circuit mill & 2-3 kWh/t for an open circuit mill, a sheer waste if this is not required ...
CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′.

If a ball mill contained only coarse particles, then of the mill grinding volume and power draw would be applied to the grinding of coarse particles. In reality, the mill always contains fines: these fines are present in the ball mill feed and are produced as the particles pass through the mill.
The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that …
Wilczek: The mill accepts a maximum particle size of about 0.5 mm for hard and up to 4mm for softer materials. One typical characteristic of the mill is the high energy density, 10-20 times higher compared to a ball mill, resulting in a very compact design. The high energy density in the small grinding chamber requires a fast material transport.
The grinding parameters were adjusted over time to maximize mill productivity under stable conditions while achieving similar Blaine fineness as the control mix (i.e., Blaine of 3850 ± 75 cm 2 /g).
