Challenges of Incline Conveying: Belt DesignIncline conveyors are some of the most useful implements in bulk materials bulk materials handling, but that doesn't mean they're equally suited for the job. The task of lifting bulk material requires some impressive engineering to do the job efficiently. A proper belt is possibly the most important input into maximizing productivity with incline conveyors. Cambelt's line of belting is designed to cover all bulk material handling needs regardless or your material to be handled or the angle of incline required.
What is Required From a Belt?One of the primary difficulties of handling powders, granules, and pellets is that they sometimes have a hard time deciding whether to act like a liquid or a solid, and they usually settle on which ever makes it more difficult to handle them. When you want them to stay put they start to flow, when you want them to flow they can start to cake. A bulk material's angle of repose and angle of surcharge are important factors in figuring out the best way to handle a particular material. These personality quirks are among their most conspicuous when you're trying to move the material up an incline. And the belt itself is your primary tool to wrangle the product where you need it to be.
Cambelt's SolutionsCambelt has been engineering belts to ease the task of incline conveying for over 50 years. Each of our belt configurations is designed to provide efficiency for a range of angles of repose and angles of incline. When utilized properly, these belts can control any dry bulk solid as well as anything you've seen. Take a look at each of Cambelt's belting products to get an idea of our capabilities.
• Straight or Chevron Cleated belts - Featuring low profile cross cleats, these belts are perfect for transporting bulk materials along shallow inclines. The low cleats are enough to hold material in place that would slide off a completely flat belt. Additionally, chevron cleats gently prompt particles toward the center of the belt as it goes. With an optimal operating angle range of 15- 25°, these belt configurations are economical solutions for conveying products with low angles of repose. Without flexible sidewalls the straight and chevron cleated belts are limited in load capacity as well as angle of incline but are well suited for many jobs in construction, mining, dry waste handling, and road surfacing.
• Trough Belts - These belts are designed to roll upward along the edges to form a trough for bulk material. These belts solve the problem of material falling off the sides, which allows for higher capacity than straight and chevron cleated belts. They are still very cost effective for lower angles of incline up to 25°. Without cleats, Cambelt's trough belt isn't built for steep climbing, but it can handle a wide variety of materials, including small powders to larger chunks. These belts are not ideal where caking can be a problem. Trough belts are well suited for moving products across long spans and for irregular pieces such as in a recycling plant. They're also effective at containing pieces on a level path that tend to roll such as tomatoes and larger chunks of ore.
• CamFlex - These belts are highly engineered for higher angles of incline and very high belt speeds. Flexible sidewalls keep material from sliding off the sides of the belt and tall nubs across the surface keep material from rolling backward as the belt moves up. CamFlex belts excel at moving large amounts of material quickly for a surprisingly high load capacity up to 45° angles. The nubs act as stakes to keep even the finest powders and all but the largest chunks in place along the conveyor path. They also serve to keep materials from clumping or caking with a steady, continuous feed. CamFlex belts are ideal for a wide range of applications from loading grain and cement silos, to transloading materials between transport vehicles, to relieving mines of their riches.
• CamWall - These belts hold material in pockets between high cross-cleats and flexible sidewalls. These belts are compatible with high belt speeds, high capacity, and high angles of incline. In fact, CamWall belts are capable of transporting at 90° angles and through changes from horizontal and back. CamWall belts can also be outfitted with buckets for the largest chunks. Built with fully-molded flexible sidewalls of 3”, 4.5”, or 6” height, your product will be easily contained, regardless of slope. With the ability to move everything from powders to large lumps, this belt is perfect for grain elevators, mines, and just about anything else with too large of chunks or too high an angle for other belts to handle.
