Conveyor belts are common. In supermarkets, conveyor belts transport groceries to the cashier. The movement is controlled automatically by using photosensitive devices that detect goods as they pass over the belt.
This is just one example of conveyor belts and how they are used in the retail sector. They are also used in warehouses and sales centers. Conveyor belts find applications in the manufacturing and mining industries as well. In manufacturing, conveyor belts transport finished products in pallets to packaging sections. But the most extensive use is in the mining industry. They are used to transport bulk materials, such as coal, over long distances in the mines.
Conveyor belts are simply flat transmission structures powered by pulleys on both ends. They have been in existence for more than a hundred years, beginning in the mining industries. Conveyor belts are used to transmit bulk goods over land, under land and over steep slopes, where manual transportation is impossible. For instance, the longest belt, about 16 kilometers long, can be found in a mine in Chile.
Conveyor belts have played a major role in modern-day assembly line production. The initial Ford cars were built in assembly lines. Belts carried car parts either overhead or along the platform, and the worker stood stationary in an assigned location. Before conveyor belts, workers had to go to wherever the car assembly took place inside the plant. From assembly lines, conveyor belts were put to use in packaging applications and other distribution activities.
According to i-conveyors.com, modern factories use a continuous process to manufacture Conveyor Belts. Apart from increasing the manufacturing efficiency, this method provides longer lengths without splicing. This, in turn, reduces the installation and maintenance cost of the belt.
Simplistically stated, a belt is manufactured by embedding the reinforcing material - textile, canvas, nylon, steel cord, or a combination of them - in polymer slabs, usually rubber, and vulcanizing it. To a great extent, the number and type of plies (layers of reinforcing materials) are major factors that determine the strength of the belt.
Steel-wire-reinforced Conveyor Belts, in which the cords are pretensioned, are extra strong. They are mainly used in mining and handling of heavy material.
Underground mining needs flame-resistant belts. The range also includes oil, chemical and heat/cold resistant belts, and belts that are acid-proof or alkali-proof.
Wire mesh belts have good heat and cold resistant properties. They come with a choice of mesh types. Some have tightly woven mesh. In others the mesh opening is large and enables air passage and water jet cleaning. Wire mesh belts can take on light or heavy loads. They can be used for bakeries, cooking lines and for freezing plants.
Over a period of operation, the belts are likely to become slack. This can be corrected with the use of tensioners, which can be automatic or manually operated. A special type of belting is required for acutely inclined and high-speed conveyor systems.
The choice of Conveyor Belt should be made with expert advice. The manufacturers and consultants would be happy to be of assistance.
