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.
For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically EUR per ton of cement. For an OK mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, whether hardfacing is applied.
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, the medium and the ...
Key benefits Flexible, modular design Low pressure drop Simple maintenance Cement grinding is a crucial stage of the flow sheet, where both cement quality and process e ciency are decided. Achieving the required fineness with maximum e ciency is down to the design of the ball mill and how well it runs.

A ball mill liner is a type of material that is placed inside a ball mill to protect the mill from wear and tear. The liner acts as a barrier between the grinding media and the material being processed, preventing excessive wear and damage to the mill. Ball mill liners also serve to contain the grinding media and prevent it from spilling out of ...

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 bypassing the partition through the center grate even ...
cone tube ball mill machinery for raw material cement. Nov 06, 2018· FL ball mill for cement grinding. The FL ball mill is designed for grinding of clinker, gypsum and dry or moist additives to any type of cement material flow through the ball charge dia meter of the cone has a flange for equipment for monitoring the bearing.
The ball mill sat at a slight angle, to compensate for the large intake than discharge diameter. That was an added feature, when I discovered the original small intake was problematic. For the record, lime was introduced to the ball mill on a regular basis, to insure that the pH was higher than 9½.
Closedcircuit Grinding System The closedcircuit grinding system of the ball mill is shown as follows: materials mixed in a certain proportion will firstly enter the cement ball mill for grinding and then be sent to the powder concentrator by bucket elevator. The powder concentrator divides the materials into coarse and fine materials.
