We operate various systems for mixing solids and liquids.
The existing mixing units allow the production of batches between 1 and 10 cbm. Different mixing tools are used depending on the requirement. Individual components can be pretreated, e.g. heated, melted or pre-crushed. It is also possible to spray fluids onto solids and to distribute them finely.
When planning our systems, we pay attention to a compact design and short product paths in order to keep the cleaning process for changing the product as simple as possible. That is also why those parts that come into contact with the product are made of stainless steel.
The systems are designed for dealing safely with hazardous substances. This includes handling solids and liquids that form explosive mixtures with air.
We offer the grinding of solids as a process engineering service. Various crushing units are available to us to meet the different requirements. We can handle numerous materials which could form explosive mixtures with air by using inert gas or in a pressure-shock-resistant system.
A variety of different special chemicals can be processed on grinding mills with integrated separation. This ensures a particularly high degree of fineness and a very selective range of grain size with comparatively low energy input.
We operate further crushing units for applications with lower particle-size requirements.
The raw material is fed onto the grinding mill as a pure material or as a previously formed mixture. We determine the grinding parameters in advance in a production test.
The systems are usually operated for production volumes at a scale of about 500 kg to over 100 tons. Trial production runs of lower volume are possible.
To facilitate handling, we offer compaction of powder materials to granulates.
The benefits of granulates include reduced exposure of dust in the application, in a usually higher, more uniform bulk density, or in improved mixability with other coarse-grained components such as plastic granules. Granulation frequently also achieves improved storage stability and dosing capability.
Numerous materials can be granulated in the roller compactor without adding binding agents, which might not be compatible with the application of the products.
The compacted product is transformed to the desired size in a suitable crushing unit and filtered to separate it from the fine component. Different grain sizes can be set according to the purpose by selecting the parameters.
Gentle compaction is possible in a vacuum-pressure rolling mill. The air trapped in the powder materials is extracted by applying low pressure to a porous compactor roller. This type of compaction can be applied as an independent process or can precede a subsequent processing step.
As a service partner, we strive to perform sub-steps in the value chain of our clients. But we also offer our services to our customers for the solution of unplanned tasks, such as reprocessing faulty batches.
Possible processes in this respect could be:
We package the customer’s own products in their specifically designed packaging.
We maintain business relationships with manufacturers and suppliers of various types of packaging materials. In many cases, we succeed in bundling procurement for various items to obtain attractive purchase prices for our customers' packaging materials.
We meet high quality requirements in packaging our customers' own products in sales packages. Trained employees conduct and document extensive inline inspections.
We have storage facilities at each of our production sites, also for chemical products from a wide range of substance groups, and thus ensure a reliable supply of starting materials and packaging materials for our production.
Space is also kept available in our hazardous materials warehouse for longer storage periods before or after processing or for pure storage services. We can store solids and liquids in transport packages over an area of around 10,000 sqm. Our employees have the necessary qualifications and experience to accept and safely handle hazardous materials. We can also organize transportation for you.
In addition to our product services, we also offer our customers additional services, such as:
- procurement of raw and packaging materials
- analytic determination of physical product properties
- laboratory formulations and storage tests
