Belt Conveyor is a continuous transportation machine with belt as the traction and carrying part. The conveyor belt winds around the driving roller and various kinds of redirecting rollers, and is given appropriate tension by the tensioning device. When working, under the drive of the driving device, the conveyor belt runs through the friction and tension between the roller and the conveyor belt. The materials are continuously sent to the conveyor belt and move together with the conveyor belt, so as to realize the conveying of materials.
Structural composition of belt conveyor:
1. Driving device: it is mainly composed of motor, hydraulic coupler, reducer, coupling, etc. It provides power for the conveyor belt to realize the transportation of goods. The driving roller is the main part to transfer the power, and the conveyor belt runs with the friction between it and the roller.
2. Roller set: including driving roller, head reversing roller, tail reversing roller and so on. Reversing pulleys are mainly used to increase the friction between the pulleys and the belt by increasing the wrap angle of the transportation belt on the corresponding pulleys.
3. Roller group: it is the part to support the conveyor belt and the materials on it, and is divided into groove-type forward tilting roller group, groove-type roller group, buffer roller group, V line forward tilting lower roller group and V line lower roller group, etc. Each roller group has the features of light weight, low running resistance, good sealing performance and long service life.
4. Tensioning device: its function is to keep the necessary initial tension of the conveyor belt to avoid slipping on the driving roller, and to ensure that the droop of the conveyor belt between the two rollers is within the stipulated range, and the main structural forms are spiral, trolley weighted, and vertical weighted.
5. Sweeping device: including the head sweeper and the return trip with the empty section sweeper, used to sweep the adhering in the transport belt working surface and non-working surface of the material, to prevent the material pollution of the environment, caused by the belt deflection as well as into the tail drum and the transport belt between.
6. Safety protection devices: such as belt anti-tear, mesh anti-tear, longitudinal tear, under-speed, heddle protection, anti-blocking, deflection, rope pulling, emergency stop and other protection devices, which can protect the belt from tearing, prevent the damage of the pulley, monitor the status of the motor, avoid the blocking of materials, prevent the belt from deflection, and cut off the power supply in case of emergency.
1. Mining industry: It is used for conveying bulk materials such as coal, ore, etc., and can realize the material transportation from underground to the ground or between different operating points in the mining area.
2. metallurgical industry: in iron and steel mills, non-ferrous metal smelters, etc., it can be used to convey materials such as ore, coke, slag, etc., to meet the demand for material transportation in the production process.
3. chemical industry: it is used for conveying various chemical raw materials, finished or semi-finished products, such as fertilizer, plastic granules, soda ash, etc., to ensure the continuity of chemical production process.
4. Building materials industry: it can convey cement, sand, gravel, bricks and other building materials, which are widely used in cement factories, building materials factories and construction sites.
5. Food industry: Belt conveyor with food grade conveyor belt can be used for conveying, sorting and packaging of food, such as processing and transportation of fruits, vegetables, meat, cookies and other food.
6. Logistics industry: in logistics warehouses, distribution centers and other places, used for conveying goods, sorting packages, etc., to improve the efficiency of logistics operations.
