Trough Conveyors

Trough conveyors are commonly used on transfer lines, small parts handling, and food processing. They share most of the design characteristics of two-axle conveyors but with the additional raised edges to contain the product on the belt. This feature requires belts to be flexible and to maintain their shape over the pulleys and on the return. They are often used on incline conveyors to hygienically contain the product.

Conveyor Construction

Troughing is one of the best solutions for containing bulk product, especially for powder or product in granular form. Troughing causes products to accumulate closer to the center of the belt. While this is contrary to the even distribution of the product over the belt surface, it gives better tracking balance to the belt and eliminates the need for containment side walling, preventing spillage or product loss. The depth of the trough can be shallow or deep but the angle at which the belt sides can trough successfully is determined by mechanical factors that include belt thickness, flexibility and width.

Why Volta is the Choice?

Volta belting material can aid in avoiding many of the pitfalls of belt failure thus saving downtime and maintenance costs. They also create a hygienic and cleanable working environment for food processing conveyors. Volta’s long-lasting welded splices can save multiple belt changeovers and Volta’s homogeneous belting material resists the strain of flexing in and out of the troughing form.

Volta SuperDrive™ and Mini SuperDrive™ are especially suited to troughing conveyors and guidelines to designing them are available in our technical manuals.
