• Axial transport in dry ball millsScienceDirect

     · Charge material is dragged upwards by the motion of the liner and then either avalanches down the free surface or is thrown through the air as a cataracting stream. The material in the cataracting stream is ballistic and is thrown by the rotating mill in the radial–circumferential plane. This does not lead to any net axial transport.

    The clinker is ground in a ball mill—a horizontal steel tube filled with steel balls. As the tube rotates the steel balls tumble and crush the clinker into a super-fine powder. It can now be considered Portland cement. The cement is so fine it will easily pass through a sieve that is fine enough to hold water.

    Clay and limestone are the basic materials for cement production. After mining and coarse crushing the rock is processed by crushers in large mills using corrective materials to raw meal and fed to further processing. The crushing process is carried out by means of rollers (roller mill) or balls (ball mill).
