Liebherr imparts independent shaft, agitator speed control on pan mixer

Liebherr Concrete Technology has announced North American market availability of the RIV 2.5 D Ring-Pan mixer, equipped with separate motors driving the main shaft and mixing arms plus agitator rotors. Rotational speeds of the shaft (7 to 34 rpm) and agitator (51 to 232 rpm) can be adjusted to specific concrete mix designs, and set at different rates for dry or wet loads and discharge cycles. Variable mixing control features make the model especially suited to high performance concrete.
