To minimize transfer waste and save capital investment, many manufacturers choose to mix in the drum they receive their product in. Our 55-gallon drum mixers are engineered to attach to a drum in a variety of ways, accommodating a variety of mixing processes. Clamp a drum clamp mixer to the side of a drum, or use a drum lid agitator to reduce splashing. Bung mount mixers thread directly into a standard bung fitting and include a folding impeller that opens up when the agitator is powered on. Drum bracket mixers allow for mixing in an open vessel with additional support by clamping to two sides of a barrel.
