The raw mill will be operate with a much coarser ball charge than the cement mill mainly because of the bigger slot sizes of the partition wall. The transition zone consists of 50 mm and 60 mm balls. The basis is a 50 mm ball size for 5% residue on the 4 mm sieve. In case bigger grains are by-passing the partition through the center grate even ...

After exiting the cement kiln, the clinker is cooled and stored. To produce cement, clinker is mixed with a small amount of gypsum and other additives, such as pozzolans or slag. This mixture is then ground in the cement ball mill. The grinding process involves passing the clinker and additives through the rotating drum of the ball mill, …

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 ...
Cement Ball Mill Structure. When Ball Mill is working, raw material enters the mill cylinder through the hollow shaft of the feed. The inside of the cylinder is filled with grinding media of various diameters (steel balls, steel segments, etc.); when the cylinder rotates around the horizontal axis at a certain speed, Under the action of centrifugal force and friction force, …
Demerits: 1. High Energy Consumption: Ball mills often require high energy input for the grinding process, making them less energy-efficient compared to some other milling techniques. 2. Wear and Tear: The grinding media and liners experience wear, requiring regular maintenance and replacement. 3.
From this experiment we got following result: 0.002389 MWh/t. Now using standard formula we can calculate grinding media wear rate: Wear Rate (g/kWh) = 0.042 * H * D^0.67 * η. H=Hardness in Mohs Scale. D=Diameter of Ball (mm) η=Efficiency Factor (decimal) Factors affecting wear rate of grinding media.
In this work, the energy and exergy analyses of a cement ball mill (CBM) were performed and some measurements were carried out in an existing CBM in a cement plant to improve the efficiency of the grinding process. The first and second laws efficiency of the CBM was specified to be 80.5% and 19.9%, respectively. The electrical energy ...
The first finish ball mill driven by a wrap-around motor has been put into operation in 1969 in Le Havre, France. The cement output is rated at 200 MTPH and the motor rating is 8700 HP (metric HP), equal to 6400 kW at …
A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.
Working principle. Fed into the mill through one or both bearing trunnions, the material is ground by impact and friction from the balls. The ground product is discharged from the mill through discharge slots provided in …

The horizontal design makes it easy to operate and maintain, and it is suitable for both wet and dry grinding. 2. Vertical Ball Mill. A vertical ball mill is a type of ball mill where the barrel is vertical instead of horizontal. It is designed for fine grinding of materials, and it is usually used in laboratory or small-scale production.

4. Sampling inside mill (mill test) Sampling of material. – Take ~1 kg sample every 1 m along mill axis. – Each sample collected from 3 point in the same cross section. – Removed some balls and taken sample. -First and last sample in each compartment should be taken. from 0.5 m off the wall or diaphragms. 4.
The equipment costs are higher for a VRM than a ball mill, reflecting the greater complexity of the system, which includes items such as the rollers, table and the hydraulic system. Overall, when equipment, erection and civil costs are taken into account, the cost of a VRM project is around 20 – 25% greater than a ball mill system of the same ...
