Conveyor belt - is an integral part of the belt conveyor, which simultaneously performs the functions of load-carrying and traction bodies. At the same time, such a part is both the most expensive and the most short-lived in the conveyor. The most stringent requirements are put forward for its strength and durability.

The tape design has the following layers:

• Working rubber lining. The surface over which the load is transported.
• Fabric (cable) pads - the frame of the product. The most important element of the tape, which determines its strength and flexibility. The number of such gaskets can be 3-12 pieces.
• Rubber gaskets that connect the carcass layers.
• Non-working rubber lining.

Also, the tape is equipped with a rubber board, which protects it from delamination and from the ingress of aggressive substances on the main layers.

According to the frame material, conveyor belts are divided into two types:

1. Rubber-fabric. Contains fabric frame. The fabric can be natural (cotton) or synthetic, with a strength of 55–400 N/mm.
2. Rubber with metal cables. Made on the basis of a frame made of steel cables. They are designed for conveyors over 300 m long transporting large, heavy loads.

When choosing a conveyor belt, the following parameters should be considered:

• width;

• thickness;

• number of carcass layers;

• type of transported cargo;

• term of use.
