A cement-free future: Flexible laboratory mixing plant for synthetic mineral materials

Sustainability and CO₂ reduction are becoming increasingly important in materials development. A modern laboratory mixing plant demonstrates how synthetic mineral materials, ceramics and artificial stones can be produced entirely without cement – in an energy-efficient, recyclable manner and at low temperatures.

Flexible plant concept for laboratory applications

The complete mixing plant installed was designed specifically for research and development processes. Extensive mixing trials were carried out in advance using a KKM L laboratory mixer (100 litres). The aim is to produce innovative, cement-free materials without CO₂ emissions and without energy-intensive firing.

Ergonomic and versatile material feeding

The plant offers maximum flexibility in terms of feeding:

• Big bag emptying station with pre-silo and integrated crane

• Three bag feeding hoppers with extraction and filtration

• Pneumatic lifting table for ergonomic working

This allows different materials to be processed quickly and cleanly.

Highest mixing quality with cone mixer

The central element is the KNIELE KKM250/375 cone mixer with ceramic lining and frequency converters. It enables:

• excellent homogenisation

• reliable processing even of the smallest batches from approx. 25 litres

• quick and easy cleaning

An integrated forced dust extraction system also ensures a clean working environment.

Precise dosing and intelligently integrated recycling

Small components and chemical additives are dosed with high precision – including via mobile small-component silos fitted with dosing screws and digital displays.

An integrated recycling system allows material to be returned to the process or into IBC containers. A closed-loop system ensures minimal losses and maximum sustainability.

Conclusion: Clean technology for a cement-free future

This laboratory mixing plant represents a new generation of cement-free material production. It combines flexibility, the highest mixing quality and a clean recycling concept – ideal conditions for the development of sustainable mineral materials of the future.
