Original crushing system instruction
The factory original chamotte crushing system: a kiln clinker through a crusher into the clinker silo, the ingredients mixture through two stage crushing 1500 vertical impact crusher closed-circuit screening system machine with rotary screen. Grain size see problems in. Feeding size by visible, particle content is more than 5mm accounted for about thirty-seven percent, so that the ball mill load is too heavy, the impact of production, increase of energy consumption. At the same time, the plant expansion of No. 3 kiln, the original system can not meet the needs of. In addition, the original system of iron removal difficult, once the piece of metal into the crushing chamber, easily broken counterattack plate and hammer, reduce the service life of the hammerhead, and generates a very large vibration and noise. Therefore, the choice of using simple process, reliable operation of the rod mill as pre grinding system.
Equipment modification
The factory adopts an idle air swept mill revamping. The main modification of air swept mill internal structure, speed and increase the discharge grate plate etc.. Equipment before and after the transformation of the transformation process related parameters of 3.2 removal of the original two to break the system, using rod mill as the pre grinding equipment, and ball milling with the composition of semi finish grinding system. Rod mill is easy to generate chaotic stick phenomenon, the factory uses the storehouse bottom ingredients, control the feeding capacity of electronic belt scale, ensure uniform feeding, to avoid disorderly stick phenomenon. Process as shown in. The results found that the increase of rod mill grinding particle size distribution, goal of the tremendous changes. First of all, to shorten the length of a warehouse, the partition board forward a lining board length, a chamber length is shortened from original 2.75m to 2.25m. second, the partition board slot spacing adjusted by 10-3.2.2 ball distribution scheme of the original feeding thin, in order to improve the efficiency of ball mill grinding, to reduce use of rod mill as the experimental study of cement pre grinding, application of rod mill as test on cement pregrinding use rod mill before and after the mill ball distribution scheme improvement of cement performance comparison of rod mill as pre grinding equipment has many advantages.
