In this step, the fabric is covered with a specially formulated and customized adhesive to give the fabric strap a solid base to which the rubber component adheres. Using a computerized system, heat is distributed to join the thread and rubber components together to create a rubber belt. A conveyor belt consists of two necessary parts: two motorized pulleys and a thick, durable conveyor material. All conveyor belts have been created for similar purposes.
However, the design and composition of each belt determine what product, weight, speed and industry the belt is most suitable for. Multiple belts can be used when biomass descends from one belt to the next, allowing a certain mixture to be produced. According to the National Association of Industrial Belts, to be defined as a lightweight conveyor belt, it must have a working tension of less than 160 pounds per inch wide. The same flame test and flame resistance criteria are applied to these materials as to conveyor belts.
Generally, conveyor belts are made of a rubber or plastic composite combined with one or more layers of textile material or steel cables of different diameters. Intelligent conveyor belts are equipped with the ability to send alerts in the event of a fault or breakdown, vary their speed at pre-programmed times and start and stop automatically. Thanks to their speed, efficiency and ease of use, conveyor belts have revolutionized material production in all sectors. Since there is limited contact between the gaseous phase and the solid phase, it can be expected that the heat and mass transfer rates of the solid bulk material passing through the conveyor belt will be reduced.
Although it has not been confirmed, many believe that the first conveyor belt appeared between the end of the 18th century and the beginning of the 19th century. Other possibilities involve the use of oscillating conveyor belts, in which the oscillation allows mixing and, at the same time, maintaining the flow of biomass through the reactor. The rubber conveyor belt material is praised for its flexibility as well as for its smooth, seamless design. This is due to the acceleration of the material in the direction normal to the belt as the belt moves from the maximum position to the position of zero sinking on each intermediate pulley.
Polypropylene is rarely used as a sliding or support material, except in isolated applications, such as guide bars on conveyor belts for the beverage industry. The diamond category in the recycling pyramid refers to collectible clothing found on conveyor belts. Environmentally friendly conveyor belts, such as those powered by solar energy or those made from recycled material, have also seen an increase in recent years. A conveyor belt can be made of polyvinyl chloride and fabric such as polyester rubber or styrene-butadiene and several layers of polyester or nylon fabric.
The SSFT is also used to determine the flame resistance of some components of conveyor belt conveyor systems.
