Fixed Stackers :
Most of the material handling systems need a device to create a storage pile of the product. This can be accomplished with something as simple as a fixed conveyor. These Conveyors are trough belt conveyors fixed in inclined position. Stacking Conveyors are used to stockpile material, usually minerals, sand and gravel, coal and other ores, for later use. They can also be designed to raise and lowered, either manually or by hydraulics.
