Tapered Twin Shaft Screw Feeders-BU

• BU Twin Shaft Screw Feeders are equipped with a tapered inlet trough following the shape of the tapered inlet sections of the two screws, enclosing them almost completely from below at minimum clearance.
• BU Screw Feeders are manufactured from carbon steel. The upper trough flange is fitted to match the outlet of the bin or hopper.

• BU Twin Shaft Screw Feeders are an option for users who require particularly efficient discharging/feeding from bins or hoppers.
• BU is designed for handling of non homogeneous materials (wood chippings, paper, etc.), materials from the flour milling industry (bran, flour, etc.), and bridging materials (e.g. sawdust, soy, etc.).
