Modular Driven Roller (MDR) Conveyor: MDR conveyors employ DC drive motors connected to slave rollers in series. These conveyors are designed with a focus on safety, as they use low torque and minimize the risk of entrapment or injury. The slave rollers are driven by the DC motors, allowing for controlled and synchronized movement of the conveyed items. MDR conveyors are commonly used in applications where safety and precise control of product flow are crucial.

Non-Driven (Gravity) Roller Conveyor: Non-driven roller conveyors rely on gravity to move products along a decline. They are often used for simple material flow or as accumulation zones. Specialized rollers can be used in gravity-driven roller conveyors to control the speed of products moving down a decline. The automatic braking feature slows down or stops the items to prevent collisions or maintain a controlled flow.
