With such a diverse range of businesses to cater for, being able to identify and produce the right conveyors for the task at hand is essential. Just as no two industries are exactly alike, the same can be said of businesses competing in the same sector. That’s why our conveyor systems are built bespoke, designed and fabricated to the exacting needs of our individual customers. Machines as seemingly simple as belt conveyors require an understanding of end use which some businesses sometimes fail to appreciate.
Depending on their construction, can be used for light and heavy conveyance, though the heavier variation tends to be used exclusively in the movement of bulk materials handling, like aggregates and raw materials, such as employed in mining. The more common variety of belt conveyors are typically utilised for lightweight materials handling, such as components, powders, products and packages, either as stand alone machines, or integrated into complete conveyor systems. They are very versatile, since belt conveyors can be designed and fabricated to any width or length in a straight line as required. Belt conveyors can also be formed into curves and integrated with straights, providing great flexibility to conveyor system footprints and routes. What’s more, belt conveyors can incorporate gradients, providing even greater layout configuration options.
Belt conveyors comprise two or more pulleys (drums) which serve a the axis that a looped belt endlessly runs around, with at least one of the pulleys being powered. As a consequence any element that is positioned by the first pulley will be moved towards the second pulley. From this point the element will either transfer onto another conveyor, or be removed from the conveyor altogether. This principle of motion is in theory eternal, and its measurement is the mechanical equivalent of the saying ‘how long is a piece of string?’. In between the pulleys the belt is supported by a series of rollers or a flat pan, depending on the material/element that needs to be conveyed.
The belt itself is either single or double layered, again depending on the material/element being conveyed. If double, the conveyor belt comprises an under layer – known as the carcass – that provides strength and shape, and is typically made from nylon, polyester and cotton. This layer will only interact with the belt conveyors pulleys and supporting rollers/pan. The top ‘over’ layer – known as the cover – is outward facing, and is the surface that materials/elements make contact with. The cover is typically made out of rubber or plastics, but can comprise use-specific materials for specialist applications, such as silicone when extreme heat is a factor.
As long as belt conveyors are constructed strongly and powerfully enough to support and move a given material or element, they can be used to convey just about any solid. As previously stated, a belt conveyors length can be as long as you like (especially if individual units are set in series) and the same is true of its width. Very wide conveyors can be constructed to accommodate large sized components, products or packages; very narrow belt conveyors for the opposite, such as when utilised in pharmaceutical production, food processing, or electronic component manufacturing. The only time that belt conveyors cannot be used is when directly exposed to abrasive or sharp materials or elements.
