It was found that the ball mill consumed kWh/t energy to reduce the F 80 feed size of µm to P 80 product size of µm while stirred mill consumed kWh/t of energy to produce the product size of µm. It also showed that stirred mill produced finer product than the ball mill at around 40% lesser consumption of energy.

Costs of all important equipment were estimated, such as SO2 removal systems with the absorber and the holding tank, reagent feed system with the ball mill and dewatering gypsum slurry system.
The entire mill feed enters the drum via a chute or spout and an internal spiral carries the feed into the trunnion liner. The drum feeder may be used in lieu of a spout feeder when headroom limits direct spouting. The drum also provides a convenient method of adding grinding balls to a ball mill. The drum is generally lined with Manganese Steel.

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
Gypsum is a precious mineral. It is widely used as a building material, with the majority of it manufactured as plaster to paint walls or create decorative materials in structures. A few gypsum ore resources contain up to 80% gypsum, ideal for plaster production. Raw gypsum may be turned into soil conditioner, cement additives, industrial and ...

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.

The Wet Flue Gas Desulphurization (WFGD) is the most commonly used method and the most efficient as shown in the table below: The absorbent required by the WFGD is generally limestone slurry made from the limestone rocks mined from limestone mining quarry through crushing, milling, and pulping.
where d is the maximum size of feed (mm); σ is compression strength (MPa); E is modulus of elasticity (MPa); ρb is density of material of balls (kg/m 3); D is inner diameter of the mill body (m).. Generally, a maximum allowed ball size is situated in the range from D /18 to D/24.. The degree of filling the mill with balls also influences productivity of the mill and milling efficiency.
