Application of Ball Mill Exclusive for Cement Paste
The Ultrafine Mill intended special for cement paste is definitely the important component of making sure the caliber of cement paste and recognizing cement paste manufacturing upsizing. At this time, there's no this kind of modular cement paste ball mill at your home and abroad to ensure several nations around the world are consistently studying and exploring. Soon after several years’ research and practice, the cement paste creation technology in our country has transformed from the industrial experimental type to the industrial output type during the scope. With the further development of the work of replacing oil with coal, our country will build a group of cement paste plants with different sizes and different technological features.
Because we did not have the experience of exploring and developing large-sized ball mill special for cement paste within the past, we have built two cement paste plants with 250 thousand t/a level, and the cement ball mills used for manufacturing paste are all introduced from other nations around the world, for this reason, it is an urgent need to research and develop the ball mill distinctive for cement paste that is suitable for the paste producing technology features in our country.
Cement paste is a variety solid-fluid fluid with complicated flowing deformation features and some granularity composing requirement. The technological key to looking into the cement paste ball mill is to improve and optimize the structural design of the existing equipment according to the factors of the generation technology features, flow deformation features and the granularity composition, and determine the performance parameter and the working conditions of the machines. The ball mill is mainly composed by the driving system, grinding cylinder, main bearing, material feeding device, material discharging device and supporting device. The material feeding system of the grinding machine adopts the spiral feeder to force materials feeding. The water pipe, pharmacy pipe and paste returning pipe and the spiral feeder are parallelly sent in to the material feeding chamber. The prefiming agent feeding mouth of the spiral feeder adopts double sealing if you want to avoid material leakage. The cylinder is divided by the partition into coarse grinding cabin and fine grinding cabin and there is rubber lining board inside the cylinder. The raw coal is sent into the cabin by the spiral feeder for coarse grinding, and following that, the materials will go into the second-stage cabin through the comb hole of the partition for fine grinding, and after that the cement paste will go into the materials discharging device through the grid plate. To be able to prevent the cylinder from deforming soon after the ball mill is stopped, there is certainly installed hydraulic supporting device under the cylinder.
