Since the angle between the horizontal cement Rotary Kiln at 2-3 °. Therefore, in this case , the rotary kiln medium limit equilibrium will not be destroyed, because the raw material mixture in the internal friction angle of about 35-45 °, the situation can also be seen from the cement rotary kiln medium shock obtained this time, the raw material of the drum as a rigid body relative to the cross section of the sector of the operation. After lengthy analysis found support in the cement kiln tug on the coal mill also has a self-excited oscillation may occur, which would lead to tug and pondering tire in dry friction conditions occur simultaneously small amplitude and finite amplitude oscillation, its genes, and self-oscillation frequency are the same, the sub-oscillation amplitude will quickly diminish. After a long period of research, it concluded that rely solely on the change in the cement kiln drum angular velocity in the case, that is, so that it exceeds the angular velocity of the falling portion of the friction characteristic curve range of the place Rotary Kiln, can eliminate the cement kiln existence of media self-oscillation, but this method for cement kiln operation is the most effective.

The outer diameter of the domestic hot kiln mostly in the 0.3 to 0.8 m. External heat lime kiln generally smaller in diameter, it is also known as rotary tube. The heat from the heating cylinder bi pass through the outer cylinder material , therefore the cylinder temperature is generally 700 to 800 degrees in a smaller diameter, the heat transfer efficiency is high, since the cylinder and the cylinder volume of the surface area ratio decreases as the diameter increases. Hao Xiaogang degrees in diameter, not deformed. We identified the following aspects lime kiln wall thickness: 1. Heating section barrel shorter life span, generally considered two, three replacement. Shall be determined in accordance with the useful life and corrosion and burning velocity calculated thickness amount of wealth. 2 due to high operating temperatures cylinder bi, and often in direct contact with the corrosive medium, generally should not use ordinary carbon steel and the need to use heat-resistant steel and stainless steel. 3 external heat kiln small diameter, wall thickness ratio for large diameter, and general kiln presumably, more in line with the ring interface Liang Jianhua erection.
