Bulk conveyors are designed to carry large amounts of material from one place to another. Often, they are used to transport raw materials, like rocks, sand, or other heavy, raw materials. Depending on the conveyor, some bulk conveyors are constructed for light duty and the transportation of lighter and less abrasive items, while others are used for transporting the heaviest and most abrasive materials available.
Since one of the first uses for bulk conveyors was in the mining industry, mining companies to this day use large conveyors for transporting heavy mined rocks and minerals from place to place. Rocks are heavy and sharp, and require the heaviest duty conveyors to transport them from place to place.
Heavy duty conveyors have many features that lighter duty conveyors do not, such as:
Rugged construction: Everything about a large conveyor is tough, from the framework to the belt, to the machine parts used to rotate the belt. This helps the conveyor last longer even under constant use and abuse.
Abrasion protection: Most heavy duty conveyors are designed to stand up to rigorous bumps and abrasive materials, such as rocks and other hard or pointed objects. While other conveyors would shred or break down with constant abrasive pressure, heavy duty conveyors hold up well.
Heavyweight belts: The belt material used in large heavy duty conveyors is made from thicker, more durable materials. This helps the belt perform better over a period of several months, or even years, and helps reduce belt replacement costs.
Large conveying motors: Many large materials are also heavier than their counterparts, which weighs down the motor. Large bulk conveyor systems use special heavy duty motors to carry the additional weight of the products to keep the belt moving smoothly even under extreme weights.
