The material conveying angle depends on the material block size, hardness, material moisture, conveyor belt speed and conveying belt on the material side pressure. Conveyor angle is bigger, the material stability is poor, the more easily lead to slip and roll material. To increase the conveying angle, first of all to increase the friction between the material and the conveying, only friction is greater than the sliding force when the conveyor belt material in order to drive stable operation. Therefore, the friction coefficient to maximize the deep groove rollers, said one of the key techniques for high angle conveyor.

1 using the 4 standard idlers which God grass roller group, convenient manufacture and maintenance;

2 two roller is in the shape of V layout, increase the pressure in the loading side, less friction coefficient is larger;

3 according to the conveyor belt into the groove design of the side roller grooved angle, maximize the delivery zone coefficient of friction;

4 roller are arranged in a double symmetry center, is conducive to the conveyor belt to run, conveying belt without deviation. Supporting roller are not in contact with the conveyor belt, is conducive to improving the life of conveyor belt.
