Ball mill cylinder is a hollow cylindrical tube, composed of several pieces of welded steel plate. The two ends of the cylinder are connected with the hollow shaft by end caps. Cylinder should bear the weight of liner, grinding materials and diaphragm plate. When running up, the machine will have a huge torque, and therefore the cylinder requires a substantial bending strength and stiffness. The cylinder should have sufficient thickness and the thickness of the cylinder diameter is about 0.01 to 0.015.Obviously, ball mill with large size need to be thicker. The grinding efficiency of ball mill is affected by the internal ventilation directly. This is a common problem of ball mill. Why we should pay more attention to the ventilation of ball mill, and what purpose we want to achieve? After you reading this news, you will know more about this question. Obviously, we would meet a lot of questions during the operation of ball mill. And we have explained you some basic knowledge of ball mill in the news we published before. How to improve the operation efficiency of ball mill is their primary concern. Here we would like to share you some effective methods for our users of improving the operation efficiency by controlling the cylinder ventilation. The function of cylinder ventilation is to discharge the fine powder in the milling silo timely, or it will affect the grinding efficiency. Secondly, it could reduce the temperature in the milling silo, avoiding the dehydration of gypsum and the block of tailing silo. When moisture content of materials is too large and cylinder ventilation is not smooth, the water vapor emissions in the milling silo will become difficult, reducing the volumein and flow rate through the materials in per unit time. When fine powder thickness on the liner is up to 1mm, it could increase the impact of the material, which led to the reduction of milling production and addition of the grinding power consumption. The simple method is to add the blower in the upper pump. And we should do good sealing of rotary screen, discharge chute and other parts to keep smooth of cylinder ventilation.
