With the development of scale of mine, belt conveyor has kept on towards large scale and presents features of large capacity and long distance. Belt conveyor with long distance and multi power has achieve successful research and development, it changes the single load-carrying way that is given by rollers and adopts multipoint electric drive. This method can address the traditional problems that are changing conveyor belts frequently and belt breakdown easily. Also, the successful development of this kind of belt conveyor can reduce the cost of equipment greatly. What’s more, its advantages are reducing thenumber of transshipment or fall of ore during operation and avoiding environmental pollution.

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.

Useful tips of selective purchasing and storing conveyor belt
Selective purchasing
1.Describe the name and characteristics of specific materials accurately, specially the particle size, temperature and if acid ,alkali resistance or special requirement. For instance, illustrate the temperature used for the heat resistance conveyor belt.
2.Describe the specific application areas, requirement specification (width, length, number of piles, thickness, etc.), especially the temperature used and convey capacity of heat resistance conveyor belt.
Storing
1.In the process of conveyor belt transport and storage , it should keep clean and keep it from direct sunlight ,rain and snow, prevent it from contacting with acid, alkaline, oil, organic solvent and other substances, and also locate it at least one meter away from heating device.
2.The temperature of the storage should be maintained between 18-40 ℃ , the relative humidity should be maintained between 50-80℃.
3. In the period of storage, conveyor belt should be placed in rolls instead of folding and it should be turned over once every season.

Installation,Debugging and Operation for Tripper Conveyors
Tripper conveyor is a mobile device which can unload materials at the arbitrary point of horizontal section of the belt conveyor, it’s a single part of the belt conveyor. The installation, debugging and operation notes are as follows:
Installation
The installation and primary debugging of tripper conveyor are finished before leaving factory, the only thing needs to place the tripper conveyor on the guide rail, and the conveyor belt should be through the pulley, roller group of tripper conveyor and make sure the conveyor belt goes by the driving pulley of head section, the turnabout pulley of tail section of belt conveyor.

Debugging and operation
Upon the completion of the conveyor belt connection, tripper conveyor cable arrangement, you can debug according to the following steps:
Please check whether the reducer is lubricant, whether there are obstacles that the tripper conveyor may collide when it walks around before start-up .
Inching run the tripper conveyor the first time in order to see if the brake of tripper conveyor is adjusted well, it can not only avoid it collides with the potential barriers, but also can check the facilitating conditions of the guide rail and the walking wheel of tripper conveyor, as well as the operation situation of every part of tripper conveyor.
After confirming all above mentioned operations are normal, the tripper conveyor can be operated on the guide rail at any point, the purpose of the test is mainly observing the walking flexibility, reliability, walking wheel and the guide rail, please adjust it if necessary.
After the above mentioned is qualified, the tripper conveyor can be put into use.

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.

What are the Components of Belt Conveyor
1. Conveyor frame parts
Including: head frame, tail frame, intermediate frame and supporting leg which are produced by cutting, welding, punching and polishing with standard channel, angle iron, steel and other.
2. Composition of other components:
i. Roller
Roller has the highest quantity and is the most carrying parts of belt conveyor. Impact roller, friction centering carrier roller, belt conveyor roller, and so on are included. The lifespan of roller is depends on the usage, usually the roller needs to be replaced every one to two years.

Power conversion device and redirection device of belt conveyor including the drive pulley and return pulley. It is durable but the bearings need to be lubricated.
It is one of the most expensive parts of belt conveyor, and also an important part to carry the materials. Hence, it needs to be maintained properly.
iv. Driving device
It is the power source of belt conveyor. Commonly motor works together with reducer, however, motorized pulley can also be used.
3. Cleaning device
Including : head cleanser, non-loaded cleanser, tail cleanser, spring cleanser and so on.
Including : pull-cord switch, running deviation switch, skid detector and so on.
Including: electric cabinet, power protection device.
All the parts mentioned above are needed to ensure the normal operation ad production of belt conveyor, hope this article is helpful!
