Handling wood pellets from a bulk bag can be approached several different ways. Assuming elevation is needed, a screw, drag, or inclined belt conveyor can work with few restrictions. Bucket elevators may have some application in combination with vibratory feeders/conveyors.
Lateral transfer alone could be achieved with vibrating conveyors, although natural frequency tuned versions could have issues with varying head loads. Horizontal motion vibrating conveyors can handle various head load conditions.
