Product Description

Key Features Upper parallel rollers, also commonly referred to as load bearing rollers or troughing rollers, are essential components of conveyor belt systems. Their primary function is to support and trough the load bearing side of the conveyor belt (i.e., the upper side of the conveyed material). This troughing action helps contain the conveyed bulk material, prevents material spillage, and optimizes the conveyor belt's load-bearing capacity.

Roller Configuration: Three rollers are the most common. A central horizontal roller forms the flat bottom of the trough, while the two side rollers are angled upward (usually 20°, 35°, or 45°) to form a V-shape or trough. Some heavy-duty applications may require five rollers for a deeper trough. Frame: The rollers are mounted on a sturdy steel frame that is attached to the conveyor structure. Sealed Bearings: The rollers contain sealed bearings (such as ball or roller bearings) to ensure smooth, low-friction rotation and protect against dust, dirt, and moisture common in material handling environments. Grease Fittings (Optional): Some designs contain grease fittings for periodic lubrication, which extends bearing life. Cushion Rollers (Specialty): Specialty Cushion Rollers are used in areas where material is loaded onto the belt. These rollers have rubber rings around them to absorb the force of falling material and protect the belt and idler pulleys from damage.

Performance Benefits

Material Control and Spill Prevention: By designing the conveyor belt into a trough shape, the conveyed material can be effectively controlled and spillage can be significantly reduced, especially when handling bulk materials such as coal, ore, grain or sand.

Optimized Load Capacity: Compared to flat belts, the trough design allows the conveyor belt to carry a larger amount of material for a given belt width, thereby maximizing the throughput and efficiency of the system.

Belt Support and Stability: They provide continuous and uniform support to the conveyor belt under load, preventing sagging, reducing stress points, and maintaining the structural integrity of the conveyor belt throughout its entire length.

Reduced Friction and Power Consumption: Well-designed rollers with low-friction bearings ensure that the conveyor belt slides smoothly, minimizes drag, and helps reduce power consumption in the conveyor drive system.

Extended Belt Life: By providing proper support and reducing sagging, upper rollers help extend the life of the conveyor belt itself and reduce wear.

Durable and Reliable: Made of strong materials such as steel and equipped with sealed bearings, these rollers can withstand the heavy loads, continuous operation and harsh environmental conditions common in industrial environments.

Applications Mining and quarrying: Essential for transporting large quantities of coal, iron ore, copper, gravel, sand and other excavated materials. Aggregate plants and cement plants: Used in all stages of raw material handling, crushing and final product transport. Power plants: Primarily used for conveying coal, biomass and ash within the plant infrastructure. Ports and terminals: Essential for efficient loading and unloading of bulk cargoes on ships, trains and trucks. Steel mills: Used for transporting raw materials such as iron ore and coke as well as finished products. Grain handling and agriculture: Used in large grain silos, feed mills and other agricultural processing facilities to transport grain, seeds and fertilizers. Manufacturing and assembly: Used for conveying raw materials, parts and finished products, especially in industries that handle bulk or heavy items. Waste management and recycling centers: Used for transporting various types of waste and recyclable materials. Any bulk material transport system over long distances or with large volumes: Requires continuous and efficient transport of granular, lumpy or powdered materials.
