A conveyor is the main transportation equipment commonly used by industrial and research enterprises. It is a continuous conveying equipment that uses the conveyor belt as a traction and load bearing member and carries out material transportation through the movement of the conveyor belt that carries the material. It utilizes the characteristics of internal friction and lateral pressure of the bulk material and is pulled by the driving roller in the direction of movement in the tape groove, so that the internal pressure increases, and the internal friction of the particles increases. When the inclination angle is within a certain range, this friction force ensures a stable state between the material layers, forming a continuous overall movement. When the internal friction force before the material layer is greater than the external friction force of the tape, the idler roller under the tape moves forward together with the material, and when the ratio of internal and external forces meets certain conditions, the material flow is stable.
