It is well known by several experiment that there is a close connection between the tention of wire and the sorting efficiency, and in time the tention of wire are several kgs and less, happen the rice inserting phenomenon immensely and as the result of this much finished rice are found out in the broken rice.
According to my calculation refer to the tention of wire and the weight of grains, it is known that the deflection result from the weight of grains only are few and the rice inserting phenomenon happens by the dynamic motion of grains and the weight of grains promote this phenomenon.
In time, the tention of wire are several kgs and less, the deflection is instable and this prove the result of experiments descrived above.
