1.7.3.2 Problem of Impact at the Chute
Study of minimum number of ply against impact at the chute, Various types of carrier are used at the chute such as ordinary carriers, cushion rollers and zero pressure rubber tires etc. Further, the materials may fall down between carriers or upon carriers (or cushion rollers). When the impact is considered, its force must naturally be taken into consideration. In this case the following factors shall be taken up. (a) Weight and Shape of Maximum Lump Various shapes may be considered, but generally they are to be considered quite irregular. (There is such an exceptional case like boulders before being crushed). (b) Dropping Speed The dropping speed is affected by the dropping height (height of chute). (c) Chute Angle Component of a force varies depending upon the chute angle and the impact force against the belt differs accordingly.
