1.the function and application of belt conveyor:our belt conveyor equipment is adaptable for stationary and mobile crushing plants.they are widely used in mining, metallurgical and coal industry to transfer sandy , or packaged materials. According to different transferring equipment, the transfer system can be one independently or multi-conveyors or combined with other transfer equipments. 2. Working principle of belt converoy: belt conveyor is a common means of transport used in mining enterprises. It uses the belt conveyance to draw and support components and transport materials by way of moving belt. It utilizes the inner friction and side pressure of loose material to increases the internal pressure from the pulling force in its moving direction produced by the rolling chamber in the adhesive chamber, thus increasing the internal friction. When inclination falls within certain scope, the inward friction force can ensure the stability between layers and create continuous movement. When the internal friction force between the layers is larger than the external force of the adhesive, the roller beneath the adhesive will move along with the material. When the ratio of internal force and external force meets a condition, the material flow is stable.
