Belt conveyor application range:
The belt conveyor is composed of a middle frame and a roller of the conveyor tensioning device, and the conveyor belt is used as a traction and bearing member to continuously transport the scattered materials or finished articles.
The belt conveyor is a friction-driven machine that transports materials in a continuous manner. It can form a material conveying process from a first feeding point to a final discharging point on a certain conveying line. The belt conveyor can carry out the transportation of broken materials as well as the transportation of individual items. In addition to pure material handling, it can also be combined with the requirements of the process in the production process of various industrial enterprises to form a rhythmic flow line. Therefore, belt conveyors are widely used in modern industrial enterprises.
Belt conveyors are widely used for horizontal or inclined transportation in underground mine roadways, mine ground transportation systems, open pit mines and concentrating plants.
Belt conveyor structure:
The belt conveyor consists of conveyor belts, rollers, rollers and devices for driving, braking, tensioning, reversing, loading, unloading and cleaning.
Belt conveyor: Commonly used are rubber belts and plastic belts. The rubber band is suitable for working environment temperature between -15 ~ 40 °C. The material temperature does not exceed 50 °C. The upward spread of the bulk material is 12° to 24°. A patterned rubber band can be used for large angles of transport. The plastic belt has the advantages of oil resistance, acid and alkali, but has poor adaptability to the weather, and is easy to slip and age. Bandwidth is the main technical parameter of the belt conveyor.
Roller: single drum (the angle of the tape to the drum is 210 ° ~ 230 °), double drum (wrapping angle of 350 °) and multi-roller (for high power). There are grooved idlers, flat rollers, self-aligning rollers, and cushion rollers. The trough-shaped idler (consisting of 2 to 5 rollers) supports the bearing branch for conveying the loose material; the self-aligning roller is used to adjust the lateral position of the belt to avoid the deviation; the buffer roller is installed at the receiving position to Reduce the impact of the material on the belt.
Roller: divided drive roller and redirected roller. The drive roller is the main component that transmits power. The single drum (the angle of the tape to the drum is 210 ° ~ 230 °), the double drum (wrapping angle of 350 °) and the multi-roller (for high power).
Belt conveyor tensioning device: its function is to make the conveyor belt reach the necessary tension to avoid slipping on the driving roller and to ensure the deflection of the conveyor belt between the rollers within the specified range.
