Maintenance Tips of Conveyor Belt

In the use and storage of conveyor belt, it should kept clean, avoid direct sunlight or exposed to rain and snow, prevent contact with acid, alkaline, oil, organic solvent and other substances, and also located at least one meter away from heating device. The temperature of the storage should maintained at between 18-40 ℃ , the relative humidity should maintained between 50-80℃.In the storage period, conveyor belt should be placed in rolls, but not folding; in the placement, it should turn-over once in every seasons. Different types and standards layers number of conveyor belt should not be connected together while used, the best connection is used the bonded process. Type, structure, standard, number of layers for conveyor belt should be used according to the reasonable choice.

 

Conveyor belt operating speed generally not more than 2.5 m/s. For large lump size, material with large abrasiveness and fixed unloading device should use low velocity. The relationship between driving pulleydiameter and coating layer of conveyor belt, supporting of driving and bend pulley and also requirement for trough angle of idler roller should according to the design specification of conveyor belt, reasonable selection. Direction of feeding should along the operating direction of the conveyor belt, use chute in order to minimize the impact of material fall on receiving belt, reduce material’s free fall distance. The feeding section of conveyor belt should shortened the spacing of idler and use absorber idler as discharge section. The belt should use striker plate with moderately soft, to avoid the rigid striker plate will scrape the belt surface of conveyor belt.

The Role of Conveyor Belt Cleaning Device

The belt conveyor is often used to transport viscous materials, such as coal dust, mud, powder materials and etc.. Some of them will stick on the working surface of belt conveyor, which cannot be removed when discharged the materials. At this time, the adhesive material will then enter the return idler, the roller become dirty as attachment stick on it. Materials enter the roller casing, thereby increasing the radial and thrust load of bearing block, causing rapid wear of bearing. The materials deposit on the roller casing will tear the rubber surface of the belt conveyor, accelerate the wear out failure of belt conveyor. If sticky materials enter the tail bend pulley, it will stick on the surface of roller. The more the viscous materials stick on it, the greater the force of the sticky materials, which will result belt deviation and increase belt wear, leading to serious consequences.

The remaining material on the belt conveyor will increase the friction force on roller, sometimes it may cause the tear on the rubber surface of belt conveyor and also the layer of roller encapsulate. If the cleaning device can function well, it can prolong the service life of the roller, belt conveyor and etc.. This shows that the cleaning device has a significant effect on belt conveyor. In the process of operation, if you want to clean the sticky material on the tail bend pulley through anthropogenic removal, it often prone to serious bodily injury or death. Hence, in order to ensure the normal operation of the belt conveyor, the sticky material must be cleaned up by cleaning device before materials enter into the snub pulley.
