Conveyor Belts have been utilised in a multitude of industries for many years. Mainly they are used for horizontal transport of products, but now advancements in the machine and belts allow them to be used also for ascending and descending product applications. Conveyor Belts are used in industrial applications but also on large farms, in warehousing, from freight-handling, down to your local supermarket and in movement of bulk raw materials.
If you read part 1 of this article, we have mainly focussed on the belt material itself. However you also have to look at the actual conveyor machine itself if you are going to get this right.
What are the diameters of all the rollers involved (And I mean all the rollers involved) on the machine? Not all rollers are visible; some can be hidden from view inside a centre drive module for example. If you know all of the diameters, then you need to refer back to the belt manufacturer’s brochure again because there will be a minimum roller diameter given for each belt material. The reason for this dimension and the reason why it’s so important is that the more rigid the belt is, the less flexible it is and the less likely it is to wrap around a small roller. If this happens you will lose traction at the drive end and the belt will rise up at each end of the conveyor, not good. On a centre drive conveyor the belt will not want to grip the powered roller and your belt could well remain stationary.
Is the conveyor an end drive or a centre drive? Centre drives usually have pinch rollers and therefore the top and bottom surfaces of the belt will make contact with the rollers, unlike with an end drive. What if you want a flighted belt? Not possible with a centre drive for this very reason.
Will the belt get wet or be cleaned frequently? If you are changing the function of the conveyor to say a food environment, then the likeliness is that the conveyor will be frequently washed. If so, then the bearings may well need to be upgraded and some if not all parts be replaced with stainless steel or plastic components.
What kind of belt tracking does the conveyor have? Some conveyors have “Crowned rollers” that are a slightly larger diameter in the middle of the roller. This is used to align the belt. Some other conveyors use welded on flights or cleats on the underside of the belt that uses grooves in the bed and the rollers to align the belt. Both methods use different belt designs, so be aware.
Conveyor Belts are used in a multitude of industries, mainly for horizontal transport but also for ascending and descending applications. Conveyor Belts are used in industrial applications but also on large farms, in warehousing, from freight-handling, down to your local supermarket and in movement of bulk raw materials.
Assume you are buying a new conveyor, or you are replacing a worn or broken belt. How do you choose the right Conveyor Belt for your product? How do you get that product to do what you want, when you want, without damage to the belt or the product? It’s not as straightforward as you might think. Here are some basic points to consider, we will look at others in later articles.
You love your product and you want to get it to where you want it, normally as fast as possible, without damage and without losing it! Therefore the product itself has a huge impact on your conveyor belt choice.
Has the product got sharp edges? How heavy is it? How light is it even? Do you want the product to grip to the belt? Do you want the product to slide on the belt, or to put it another way the belt keeps going but the product stands still at a stop perhaps (this is called accumulation). How hot is the product? How cold is the product?
Belt materials will have minimum and maximum temperatures within which they will work, but outside of which they will perish in one form or another. Some belts are designed to grip the product, which is fine if you are going uphill or downhill, but what if you want to queue theproducts, or swipe them across the belt? A high grip belt will give you headaches if you want to slide the product as it’s amazing sometimes how much grip they have. Conversely, if you are conveying uphill, a slippy belt surface will result in theproducts perhaps sliding back down. Because of the multitude of uses, belts with many different surface characteristics are available and may be used for many different product characteristics.
Fortunately, most belt manufacturers issue very detailed data about conveyor belt materials. They want you to be happy but they also want to cover themselves and make it clear what their product will and won’t do. Make sure you use the manufacturers’ instructions when choosing your belt. If it’s a big expensive belt, get a salesman in. Belt prices can vary greatly so always get a second price. The right choice will mean you get many years of good service from your new belt. Make the wrong choice and you could be shelling out for a new one very soon.
In part 2 we can look at the characteristics of the conveyor machine itself and how that can affect your belt choice.
Scientific and technological advancement led to the invention of a number of useful systems and tools. Our life has become easy and smooth. There are a number of items that are designed to meet our requirements in the best possible way. Not only the householders but various industries are also using these systems.
In 1901, another improved system was invented. It has helped the transporting and manufacturing technologies in ways more than one. The product is motorized belts. It was first designed by Sandvik, a Swedish company. Since the time of its invention, Conveyor Belts have become an important part of our modern life. In 1913, huge numbers of belts were produced to meet the requirements of the people. With the passage of time, more and more Conveyor Belts are designed. From designing the Hubbel telescope to the assembling vehicles, belts are used for different purposes.
belts are used in different areas. From modern airports to shopping centers, belts are used everywhere due its high functionality. Large belts are used in the airport to help the passengers travel from one area of the airport terminal to another portion. Large belts are designed to into the different segments of the floor. You just need to step on to reach your destination. It is done with the help of these belts. Conveyor Belt technology is also used in the designing of the escalators. This type of belts is common in distribution centers and warehouses also.
These are used to move inventory from one area to another area, either for loading the items on the vehicles for delivering elsewhere or within the store house as a method to rotate replenish stock and inventory. Mining industry also use belts. These products are used in mining sector for moving salt, coals and other items. belts help to transport these products from the place of mining to the tips are where they are loaded onto trains and trucks for transport to customers.
The leverage of the wheels and the pulley system are utilized in the belts to move the commodities within a short distance quickly. These improved products are used in various industrial areas, like agriculture, retail, transport etc.
There are various types of belts. They are designed for several purposes. If you are engaged to any industry and want to buy these belts, you have to make it sure that the quality of the item is good and it can fulfill your requirement. Look at the width and breadth of the belt.
