\nThe KKM maintains excellent quality even for small batches from 15% of useful volume.<\/p>\n
\nIts kinematics accelerates fines dispersion and binder hydration on complex formulations.
\nIt remains a reliable option for high-performance concretes, mortars and insulation materials (lightweight concretes based on perlite or vermiculite).<\/p>\n
\nIts sealed design allows water to be added first and thus performing grouts without leakage. The conical vessel and ease of cleaning permit separate handling of water with anhydrite, limiting cross-contamination.<\/p>\n
\nAutomatic (KKM): with three high-pressure rotary heads and a telescopic lance, full wash 8\u201310 min, intermediate rinse 1\u20133 min. No residue remains at the bottom after manual or automatic wash.<\/p>\n
\nThe conical KKM discharges by gravity: up to 99% evacuated, without segregation and without residue in the vessel. A 2 m\u00b3 vessel empties in 3\u20134 s, subject to the receiving hopper\u2019s capacity. The absence of a flat bottom limits residues, avoids segregation and maintains homogeneity to the last drop.<\/p>\n
\nFor productions requiring rapid homogeneity, efficient discharge and versatility (special concretes, UHPC, SCC, technical mortars, batches with fibers or pigments), the KKM is generally the most relevant: its counter-rotating kinematics and conical vessel promote very rapid dispersion, with configurations reaching up to 350 rpm and 2\u20133 minutes mixing time even for very specific concretes such as UHPC. R&D teams and innovation-oriented units value its repeatability, the ability to switch formulas, and the possibility to produce from 15% to 100% in the same mixer with minimal concrete residue thanks to the conical shape and bottom trap. Its discharge system limits non-conformities, facilitates color changes and reduces wash-water consumption\u2014an asset for organizations committed to environmental initiatives. For sites prioritizing throughput and machine availability, the KKM\u2019s short cycles + quick cleaning secure the sequencing of small and large batches and improve overall productivity.<\/p>\n
\nIf speed, discharge efficiency and waste reduction are essential to your production challenge, the KKM conical mixer is the ideal solution for industries such as precast seeking cost optimization, high performance, great mix homogeneity and effective incorporation of admixtures. KKM\u2019s undeniable advantage is its fast, complete discharge and simplified maintenance, while reducing losses and environmental impact.<\/p>\n
