Ring-pan mixers by Liebherr have been successfully in operation in concrete plants for many years worldwide. The new RIV 2.5 D ring-pan mixer raises the standards for production of high-quality concrete mix even higher.
An advantage of all Liebherr ring-pan mixer systems is the ring-trough system. The special form of the ring canal guarantees that the complete mix is forced to flow to the mixing paddles or tools and is completely homogenized very rapidly. The mix cannot avoid the tools. A new feature is the infinitely adjustable speed of the double-agitator system, independent of the main gear. Two high-performance electric motors drive agitator and agitator system mechanically independent from each other. The advantage is that the speeds of the tools can be optimally adjusted, depending on the progress of the mixing process. The two agitator tools are fixed to the main agitator at different distances, guaranteeing quick and optimal mixing in all areas. The agitator tools ensure, moreover, perfect bonding of the cement paste.
