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.

Command Alkon secures patent on mixing process, strength predictability

Command Alkon product design and programming veterans Bob Phare and Charlene Hohl have been awarded U.S. Patent No. 9,533,429 – System and Process for Mixing Concrete Having Desired Strength Characteristics. It covers methods for a) rapidly determining the predicted strength of concrete prior to pouring; and, b) creating and maintaining a database in which mix designs and their performance characteristics can be logged and updated as hardened concrete’s actual strength is measured. Functions based on the technology will be incorporated in future versions of the quality control platform, COMMANDqc.
