6. BALL MILL • A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. • It is partially filled with balls. The grinding media is the balls, which may be made of steel (chrome steel), stainless steel, ceramic, or rubber.

Diaphragms'•Mill diaphragms are provided with slots through which material and venting from 1st compartment to the 2nd compartment.air passGrinding Media •The mill chambers are partially filled with steel balls having diameters ranging from 90 mm to 60 mm in 1st compartment and from 50 mm balls to 17 mm Ball in the 2nd compartment.

What's more, the ball mill can be used for the dry and wet grinding for all kinds of ores and other grind-able materials. The hot sale ball mill models are 900*1800, 900*3000, 1200*2400, 1500*3000, etc. 1. High-efficiency. Our ball mill adopts rolling bearing support instead of sliding bearing support with bearing bush.

Cement Grinding Stage. In raw grinding, a ball mill with a high efficiency separator is used to achieve uniform particle size in raw mix for the next stages of the manufacturing process. At the Cement Grinding Stage, 90 – 95% of the clinker is mixed with gypsum and ground in a Cement Ball Mill to produce quality cement OPC 43 and OPC 53.

1.Axial/radial runout. 2.Alignment of the drive trains. 3.Uneven power splitting. 4.Centre distances variable. 5.Face load distribution. 6.Sealing of the girth gear. 7.Girth gear is through hardened only, fatigue strength is limited. -Dynamic behaviour. -A lot of individual rotating masses risk of resonance vicinities.

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, …

than ball mills, even if the ball mill is combined with a roller press. This and further arguments led to the increased share of VRM for the grinding of finished cement. Taking into account that VRM usually have a bigger output than ball mills, it can be declared that the major part of the cement production with newly installed mills comes from ...

Ball Mill Working Principle And Main Parts · Ball Mill ball mill is one of the new high efficient grinding machine,which is widely used in the in various types of stone grinding plant, ore benefication, electricity, cement and chemical industriesThis new type ball mill with high comminution ratio, it can carry out dry or wet pulverizing and can meet demand …

The ball charge typically occupies around 30%-36% of the volume of the mill, depending on the mill motor power and desired energy consumption and production rates.

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.
