A vertical spindle mill is also designed for pressurized and suction type requirements. Boiler designers use this type of mill for poor quality coal as this type of mill rejects foreign materials like stones and other high density materials. The power consumed by the mill per ton of coal ground is only two-thirds of the ball .

Exploring ball size distribution in coal grinding mills ...Traducir esta página

J is the ball filling fraction. ρ charge is the overall charge density calculated as follows: ρ charge = total coal mass + ball mass / J ∗ Mill volume. α is the angle of repose, which is estimated to be about 35°. Mill capacity increases linearly with increasing ball load for both ball sizes within the considered range.

However, close packing of the charge rarely occurs and an operating bed porosity of 40% is common. Overcharging results in poor grinding and losses due to abrasion of rods and liners. Undercharging also promotes more abrasion of the rods. The height (or depth) of charge is measured in the same manner as for ball mill. The size of feed particles ...

the coal happens through the ball charge inside the mill where the coal is crushed through the rolling action of the balls on each other as well as the side of the mill. This continuous milling takes place until the coal is pulverized enough to be taken up by the air passing through the mill and then fed to the classifier and then to the boiler.

Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.

Difference Between Sag Mill vs Ball Mill - .Traducir esta página

The ball charge of a SAG mill is about 29% to 30%. By friction and influence of tumbling balls inside rotating cylinder grinds the raw material to the required fineness. The internal machinery of ball mill grinds the raw material into the powder-like material, And if extreme fineness and refinery are required then rotation go on continue.
