At present, belt conveyor is used in all walks of life, such as coal conveying in power plants, bulk materials conveying in steel and cement plants, and ship loading and unloading in the harbor. According to the process requirements, the belt conveyor is very flexible from one or more points of material, or can be unloaded to many points or several sections. Belt conveyor becomes a main conveyor line when feeding to conveyor belt at several points at the same time (such as conveyor under coal bunker of coal preparation plant) or along any point in the length direction of belt conveyor through uniform feeding equipment.Matters needing attention in the use process of belt conveyor:1. The conveying capacity is obtained under the condition that the material density is 1.0t/m3-1.6t/m3, the inclination angle of conveyor is less than 18 degrees, and the material stacking angle is 30 degrees.2, material density can be conveyed below 2.5t/m2.3, the transmission length is not limited to the values listed in the table, and can be manufactured according to the needs of users.
