Spray Drying – Granulating and Drying in an Efficient Process
Spray drying of viscous suspensions combines efficient granulating by means of atomization with careful drying of the droplets in flight by means of a hot gas atmosphere. This procedure enables to produce precisely conditioned powder qualities and materials for most various requirements.
We at DORST TECHNOLOGIES can pride ourselves on proven and acknowledged expertise in the processing of granules for the challenging forming of ceramic and hard metal materials by pressing with the focus being on constant bulk density, flowability and pressing behavior to achieve an optimum green density. This combination of powder processing and forming by pressing provided from a single source results in a technology package from the market leader that is unparalleled in all the world.
Yet, the procedure and the plant engineering are basically also suited to the production of dry organic and inorganic precursors for the chemical and construction materials sector as well as for special applications.
We will thus happily meet the challenges of your specific requests.
Our range of services covers the entire handling of the project from planning to assembly management right up to the complete process-related commissioning of the plant with customer material. Upon request, we naturally also supply turnkey plants that are immediately ready for operation.
