RUBI offers a wide range of mixers for mixing cement mortars and materials with high density or low fluidity. The mixers in this series feature a threaded M14 x 2 connection that can be used directly with RUBIMIX mixers and other well-known brands. The mixers for welding mortars have a head shape that ensures the material moves from the bottom to the top during mixing.

The heads of these mixers cause the mixture to rise at low speed through the center of the mixer and then fall on the outer side of the mixer. This working method guarantees the production of an extremely adhesive and homogeneous material, such as welding mortars, cement mortars, and bonding materials with enhanced flexibility (category C2) for ceramic tiles. The shape of the head allows the user to work with less effort and at higher speed. The 3H mixer head features 3 mixing edges for increased performance.
