Belt Conveyor Systems

In all countries, industries that are both small and large require efficient methods of transporting raw materials, parts, and products from one area to another. In the past this would have involved many hands, but today it is far more productive to use belt conveyor systems. They are also a lot cheaper than the cost of hiring a team of workers to constantly be moving material and products from A to B.
At first glance most belt conveyor systems can seem like a complicated design, but the basic concept is simple. A motor drives a belt made out of rubber, plastic, metal, or a strong fabric. They have a wide range of applications across many different types of industry, for example handling cement, rocks, food, parts, and more.
As mentioned above, a belt conveyor would help any business reduce labor costs. The first belt conveyor systems came about in the early part of the twentieth century as industrialization and manufacturing increased dramatically. The automotive industry was one of the first to understand the potential for belt driven conveyor systems; they helped to improve productivity as workers could stand in one place while the partially assembled cars were transported from area to area inside the factory with the minimal of effort.
If speed and space are important considerations to you then a conveyor belt can make a real difference to your productivity. They can be customized to fit almost any situation or workplace.
Perhaps the greatest advantage of a belt conveyor system is their flexibility. There is almost no end to their applications. Apart from production lines they are also an essential piece of equipment for many aggregate industries such as mining. An aggregate belt conveyor would have been designed to carry heavy loads; they would typically feature impact beds that help in absorbing the force of the loads. If maintained correctly any conveyor belt system can be in service for years if not decades.
There are also specialized belts available. For example some feature side guards to ensure no product can spill or tumble off the line. Also there are magnetized belts available which are normally utilized by companies involved with scrap metals. Other designs include steel belts to transport hot parts and products and sanitised belts used in the food processing and distribution industries.
A belt can be set up to run in a curve or a straight line. Where space is less it is possible to use a belt that has a low profile. It is also possible to splice and join belts together for an increased reach.
Whatever you plan on using the conveyor belt for it is important to check it over every week, or perhaps even daily, for wear and tear. If too much weight is placed on a belt it can crack and split which would have a dramatic impact on your companies production line. Also a damaged belt can be a real threat to the health and safety of those people in proximity.

Crown Conveyor Pulley – How it Works

Pulleys, which may be drum-type or roller-type, are the most common simple machines used to drive the belt of most conveyors systems. Because of its wide use, manufacturers have made improvements for better system performance and longer life. One of these is the crown conveyor pulley.
Pulleys are tubular-shaped drums that are used to drive the belt of a conveyor system. The drive pulley is connected to a motor, which, as a result, transfers the torque required to steer the conveyor belt. Consequently, the conveyor belt moves along the path. However, because of its mechanism, the common problem for most conveyor pulleys is the tendency of the conveyor belt to move sideways or away from its supposed track. When this happens, the belt is exposed to excessive wear as it rubs against the conveyor frame and in effect, it deteriorates faster. Also, the rubbing causes friction, which, in turn, results in increased drive motor load and power consumption as well.
This is where crowned pulleys come in useful. They are installed to ensure that the belt is on track and not drifting sideways. Whether tapered or trapezoidal, crowned pulleys consist of a drive pulley with a center diameter that is slightly longer than those of the ends. The diameter difference causes the belt to correct itself by constantly moving back on its track as soon as it tends to drift away.
Its drawback, however, is the cost. The material itself as well as the machining process causes it to be a bit expensive. At present, heavy metal is used for the wall tubing of the crown. And during the machining process, substantial unusable portions of the material are wasted.
As the belt conveyor moves, the drive pulley tends to slip. This led the manufacturers to develop drive pulleys with smaller diameters. But because the diameter is smaller, there is less surface area contact with the conveyor belt. This, in turn, results in limited torque transmission. To solve this problem, engineers thought that molding rubber or some synthetic material to the drive pulley surface would increase the grip and, in effect, torque transmission. The rubber covering is what they call lagging. Lagging provides the necessary traction in order for the pulley to work more efficiently.
Rubber material is compounded and applied to the pulley. Manufacturers do vulcanized lagging in different degrees of hardness according to customer specifications, in any diameter or length. There are various patterns to choose from – plain, ceramic, crown, herringbone and groove patterns. However, this may be expensive. The process of placing the rubber to the roller and the material itself is relatively high in cost. There is a cheaper alternative to lagging, which consists of wrapping the lagging. The result is a crown-like effect on the pulley. The disadvantage of this type of lagging is the effect of stretching the conveyor belt.
Crown conveyor pulleys can be very useful, if you know how to use and take care of it. Proper machine handling and maintenance can do wonders in increasing its life. So if you are thinking of using one of these for your plant or business, know the basic mechanism and find the useful innovations made on it. While it may be costly at first, but in the long run you are able to save your money because of the many years that the machine can serve you.

Important Information About the Work of Conveyor Belt

Steel Mesh Conveyor Belt

Steel Mesh Conveyor Belt

It is known that a conveyor belt is very beneficial for industrial. However, some people maybe still do not have an idea about the the way this equipment works. If you want to know about the work of this equipment, you have come to the right place. Just take a look at the following information and you will know how this equipment works.

Basically, conveyor belt is a very wide belt that is attached to a loop and to two or more turning rotor which is driven by motors. Meanwhile, the loop is an actual conveyor belt that is commonly made of two or more layers of rubber. One of the layers has a function for giving structure and shape to the belt, while the other layer has a function for allowing the tool in transporting its load safely. Generally, the loop is attached to the two wheels that are called rotors. These rotors are rotated by motors. Additionally, this equipment is made with enough friction between it.

Moreover, when the rotor is turning, you will find that the conveyor belt will also turn based on the intense friction between the belt and the rotor wheels. The turning motion of the rotor can cause the moving of one side of the belt in one direction, while the other side is moving in the opposite direction. It means that the wheels should always move in relatively same direction. Additionally, you need to pay attention in the moving of the two rotor wheels. If they move in the opposite direction, you will find that this equipment will not travel at all.

Furthermore, conveyor belt actually comes from the word convey that has a meaning of sending or transmitting. That is why this tool is used for sending or transporting materials. You can find that this equipment is commonly used in the industry, raw materials or convey products.
