Conveyor belts come in three types: basic, sandwich snake, and long. They are used to transfer materials quickly and with minimal human intervention. The belts consist of a metal frame with rollers and a smooth rubberized material. The sandwich snake conveyor holds products in place while moving up steep slopes, while the long belt conveyor can reach up to 13.8 km in length and is often used in mining operations.
There are three different types of conveyor belts: the basic belt, the sandwich snake belt and the long belt. A basic belt conveyor consists of two or more pulleys that hold a continuous length of material. These types of tapes can be motorized or require manual effort. As the belt moves forward, all items on the belt are pulled forward.
Common installation sites for conveyor belts include packing or parcel delivery services. This industry often requires a method to transfer materials from one location to another quickly and with minimal human intervention. The belt is typically installed at waist height to improve ergonomics for personnel interacting with materials.
The conveyor structure consists of a metal frame with rollers installed at various intervals along the length of the conveyor belt. The belt is typically a smooth, rubberized material that covers the rollers. As the belt travels across the rollers, items placed on the belt are transferred with a reduced amount of friction, due to the use of multiple rollers. Basic conveyor belts also have curved sections to allow the belt to move product around corners.
The sandwich snake conveyor consists of two separate conveyor belts which are arranged parallel to each other and hold the product in place as it moves along the belt. This type of belt is used to move objects up steep slopes, up to 90 degrees. Created in 1979, the snake sandwich conveyor was designed as a simple and efficient method of moving rocks and other material out of a mine.
The system was designed to use widely available hardware and used simple principles to ensure it was easy to repair. Any type of mechanical system intended for use in mining operations must recognize limited access to parts in remote areas. This system offers the ability to move a large volume of material at a constant speed. Smooth surface belts allow automatic cleaning of conveyor belts with the use of scrapers and ploughs. The design is flexible enough to allow materials to be redirected off the conveyor at any point via simple redirection.
The long belt conveyor is a system of three drive units used to move materials over long distances. The most important feature of this system is the ability of the rollers to handle both horizontal and vertical curves. The long belt conveyor system can reach up to 13.8 km (8.57 miles) in length. This type of conveyor belt is often used in mining operations to transport materials to remote construction sites or construction locations, such as the bottom of a mining pit.
