Power ratio method of small grain drying machine

Small grain dryer power ratio, in fact, is the ratio of the circumference of the driving drum of small grain dryer. The ratio method has three kinds.

(1) small and medium grain dryer driving drum circumferential force arbitrary distribution method, driving drum circumferential force arbitrary allocation method is more suitable in the expansion project make full use of the existing driving device for use, should not be used for new equipment in use.

(2) the minimum tension method of small grain dryer, the greatest feature of the minimum tension method is to maximize the use of the driving drum around the package angle, so that the maximum tension of the conveyor. However, when the power is large and the two driving drum circumferential force difference is very large, do not use the type of drive device. Moreover, due to the conveyor belt tension decreases, often conveying belt tension can not meet the two supporting roller sag requirements. Therefore, it is necessary to increase the tension of the belt conveyor, the calculated maximum tension minimum value is meaningless.

(3) small grain dryer equal power allocation method and power allocation method is the conveyor running total power or the total circumferential force into several parts, arbitrarily assigned to each driving roller, by their respective responsibilities and the driven roller slip condition is satisfied. Its power ratio i=1:1, 2:1, 1:2.
