4.2 Functionality
The small silo inoCOMB Cabrio is used for mixing and con-
veying pumpable (mineral or organic products) materials up
to approx. 8 mm grain size. Dry mortar, screed material or
floor levelling compounds pre-mixed by the material manu-
facturer can be used. The material hopper of the small silo
can optionally be filled with bagged material, with one-way
containers or with big bags. During operation, the dry ma-
terial is conveyed from the material hopper into the mixing
pipe via the metering shaft. In the mixing tube, the dry ma-
terial − with the addition of water − is mixed with the mix-
ing shaft to form a homogeneous, pasty or liquid product.
At the outer end of the mixing tube, the mixed material falls
directly into the pump hopper. In the pump hopper, the ma-
terial is transported to the pump unit (rotor/stator) via the
pump shaft. The material is pumped from there via the ma-
terial hoses to the processing location. There, it is applied to
walls and ceilings with appropriate spray/adhesive guns or a
reprofiling sprayer or poured directly onto the floor.
