Multifunctional Unit SpAF 400 L for Sweden

Today, a unique system leaves the factory gate (like most of our tailor-made technologies, by the way).

This is a multipurpose device that serves as both a filter dryer and a crystallizer in the previous process step. An interesting feature is the hydraulically lowered lower part of the filter using a manually operated hydraulic pump with lever.

The client is a science-led biopharmaceutical company from Sweden

Die kleinste Gipszentrifuge der Welt mit Trommeldurchmesser von 630 mm und Trommelhöhe von 400 mm

The largest and smallest gypsum centrifuge in the world

It has been almost a year since we reported on the delivery of the world’s largest gypsum centrifuge (1800 mm basket diameter) to the Slovenian Titanium Dioxide producer Cinkarna Celje. It was by no means the first centrifuge of this size produced.

However, we are pleased to inform you that, to our knowledge, the smallest automatic gypsum peeling centrifuge in the world has also been built. The customer is a municipal waste incineration plant in Germany. The centrifuge has a basket diameter of 630 mm and a basket height of 400 mm.

Generally, the centrifuge serves to remove easily soluble salts by washing and FGD gypsum dewatering to a moisture content of less than 10%.
