Where there is sufficient slope for material flow, air slides systems provide the most advantageous solution. In this case, although the system cost required for the plant is drastically reduced, a wide range of materials can be transported at very low speeds. Pneumatic conveying systems can be considered as a form of dense phase conveying systems. In this system, more raw materials or products can be transported with less energy. Conveyor systems have the lowest energy cost and maintenance cost is the lowest transport system.
