Mar 06, 20191. Preventive measures for longitudinal cracks. The main causes of longitudinal cracks in the rotary kiln shell are caused by insufficient rigidity of the shell, large temperature stress and additional stress. Therefore, in the design and manufacture process of the rotary kiln, the thickness of the cylinder shell should be appropriately increased.

A stamp mill consists of a set of heavy steel (iron-shod wood in some cases) stamps, loosely held vertically in a frame, in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating shaft.As the cam moves from under the stamp, the stamp falls onto the ore below, crushing the rock, and the lifting process is repeated at the next pass of the cam.

Working Principle of Rolling Process: The rolling process is a metal forming process, in which stock of the material is passed between one or more pairs of rollers in order to reduce and to maintain the uniform thickness. This process is mainly focused on the cross-section of the ingot or the metal which is forming.

In the ball mill both shearing and impact forces are utilized in the size reduction. The unit consists of a horizontal, slow speed-rotating cylinder containing a charge of steel balls or flint stones. As the cylinder rotates balls are lifted up the sides of the cylinder and drop on to the material being comminuted, which fills the void spaces

As the ball mill rotates, the steel balls in the cylinder rise up one end of the inside surface of the mill and eventually tumble down to the bottom. The raw material is fed into the ball mill at the ends, and the steel balls impacting together eventually grind the material into a powder which is collected through slots at the center of the mill.
