Differences in Cable and Tube Conveyor Diameters

A cable and tube conveyor system is completely enclosed. It is used to safely transport ingredients for food and feed processing. Different sized separate compartments cradle ingredients of any size through each processing stage without being exposed to outside air, particles, or excessive employee handling. The compartments are adjustable by moving the disks to create the exact size needed for specific production runs.


The component of the system that is not adjustable is the diameter of the tube. The holes required to install the conveyor system to travel from one floor to another or through existing walls are cut to size for minimal structural alterations. It is essential to get the maximum diameter needed for the operations of the business. It is the diameter that effects the speed, weight, and distance the conveyor can handle during any production run.

A two-inch diameter, for example, can support three-thousand pounds going through the system per hour. The four-inch tube supports twenty-two thousand pounds per hour, with the six-inch tube supporting up to forty-five thousand pounds per hour. The lower the total weight, the higher the speeds of the conveyor. Business owners can learn more here about all the specifications of each diameter.

Materials Used in the Design

Every conveyor system is custom designed and installed to accommodate processing needs. The diameter is one of the main factors considered when the thickness and materials are being chosen for the conveyor. Lighter materials will also contribute to the speed of the system. The six-inch diameter tube will be housed in thicker materials to prevent buckling or denting under the weight and pressure.

Other considerations for materials include the climate for systems that will be going from building to building. Budget, configuration of the space, and the variety of directions the tube has to move are additional factors. If unsure which diameter is needed, the on-site assessment by an experienced company engineer will inform the designers which option will provide the best performance. It is helpful to have the weight of the heaviest ingredient that will be moving through the system. Owners can learn more here to be well-prepared for the initial consultation.
