Powered roller pulleys are suitable for handling heavier loads, bulk materials, or items that require controlled movement and precise positioning.
• Tapered Roller Pulleys: Tapered roller pulleys have conical-shaped rollers that gradually decrease in diameter from one end to the other. The tapered design allows for smooth and controlled material flow. These pulleys are often used in applications where there is a need to merge or divert materials from one conveyor line to another. The tapered shape of the rollers facilitates the gradual adjustment of the material’s direction, ensuring accurate sorting and distribution.
• Idler Roller Pulleys: Idler roller pulleys are used as support rollers to maintain tension and alignment in conveyor systems. These pulleys are not motor-driven and are typically positioned in areas where the belt changes direction or wraps around other components. Idler roller pulleys help reduce belt sagging, maintain proper belt tension, and prevent misalignment, ensuring smooth operation and extending the life of the conveyor belt.
• Grooved Roller Pulleys: Grooved roller pulleys have specially designed grooves or channels on the surface of the rollers. These grooves provide better traction and grip on the conveyor belt, preventing slippage and ensuring reliable material transportation. Grooved roller pulleys are commonly used in applications where there is a need to move materials at an incline or decline, or when handling materials with high friction properties.
• Impact Roller Pulleys: Impact roller pulleys are designed to withstand the impact and shock caused by heavy or abrasive materials. These pulleys have reinforced construction and are often equipped with rubber discs or shock-absorbing components to minimize the damage caused by the impact of materials during loading or unloading. Impact roller pulleys are commonly used in applications such as mining, quarrying, or industries involving heavy-duty material handling.

These are just a few examples of the different types of roller pulleys available. Each type offers specific features and advantages tailored to different material handling applications. It’s important to select the appropriate type of roller pulley based on factors such as load capacity, material characteristics, conveyor layout, and operational requirements to ensure optimal performance and efficiency in material handling operations.
