Our products

Product category: Aluminium, aluminium alloys


Vacupress systems are used for deaeration and compressing powders smaller than 40 µm.

They are used as compactors before packaging units. Clear practical benefits are the reduction of transport volume and minimization of dust generation or even improvement of handling properties for the end user. The Vacupress systems can also be used as a dosing unit for better incorporation in downstream processing steps or as pre-compression unit along with granulators.  Volume reductions of up to 75% can be achieved.

The product is compressed very carefully. The properties of the products handled are hardly changed due to the relatively low compression forces used in the process. The product flakes generated in the process can be returned to their fine powdered state at any time without the application of high shear forces.

The Vacupress is suitable for bulk material weights of less than 750 kg/m³ and temperatures of up to 100°C.

Rotary Heat Exchanger

Rotary heat exchangers can also be designed as recuperative tubular coolers. With the indirect air-cooled rotary coolers from Grenzebach, the energy of heated solids can be recovered from high-temperature processes. A clear contribution to the energy efficiency in process engineering. The product inlet temperatures can be up to 1000°C.

The coolers are often used behind kilns heated using hot gas (e.g. rotary kilns). On the one hand, heating the kilns requires a lot of primary energy. On the other hand, the finished product has to be generally cooled to prepare it for transport or further processing. The contact between the solids and cooling air takes place indirectly using internal tubes, which rules out the air from getting polluted by dust. The use of dust-free cooling air heated to 200 - 300°C in furnaces enables up to 15% saving in primary energy.

Typical products are titanium dioxide and other inorganic chemical products.

Whirlwind Mill

The Grenzebach whirlwind mill offers application benefits especially in the area of fine and super-fine grinding of soft and medium-hard products up to Mohs hardness level of 5. Existing complex systems, consisting of expensive sifter mills or conventional beater mills with downstream sifters, can be replaced with a cost-effective whirlwind mill. This is efficient process technology. Throughput rates from 50 kg/h up to 20,000 kg/h can be achieved at product temperatures of up to 200°C.

In addition to the super-fine milling in the range < 100 µm, Grenzebach's whirlwind mill has especially proven itself in the area of shredding organic substances (paper, cardboard, cellulose, etc.), grinding coating, cryogenic cold-milling, milling-mixing as well as milling-drying.
