9 Types of Conveyors

12   Cable conveyors can transport people or big bulks of materials Its mechanism is dependent on moving cables with one or more spans Most people refer to cable conveyors as cable cars Cable conveyors can cover long distances of many kilometers They are also known as ‘aerial tramways’ or ‘ropeways’  The four basic elements of pneumatic conveyors are a source of air, a device for feeding material, a convey line and an airmaterial separator These conveyors move material through a fully enclosed line What Are The Different Types of Conveyors?
