Purity is Nothing Automatic.
In the nonferrous metal sector our activities focus on fluidized bed processes for ore processing and transformation. Jünger+Gräter is specialized on the design, project management and construction connected to fluidized bed alumina calcination and roasting furnaces for pyrite, zinc and other nonferrous metals.
In the past rotary kilns were used for calcination of bauxite. Today fluidized bed reactors are almost exclusively used for this process due to better economics and energy efficiency.
Jünger+Gräter has installed refractory linings in such plants around the world. Our enormous expertise in fluidized bed technology supports our engineering and the right choice of the refractories. Consequently, our customers can always rely on our “proven design“. In the zinc roasting sector J+G focuses on the complete remodeling and replacement of existing old furnaces. In addition to normal maintenance, we offer our customers the replacement of old furnaces within a short time period to minimize the production shutdown period.
A further highlight of Jünger+Gräter for such furnaces is the mold-free installation of the self-supporting crown having a diameter of up to 16 meters. Our installation specialists have done such installation work around the world. Jünger-Gräter also offers their customers in the aluminum industry competent consulting and project management for anode and smelting furnaces. Customized solution concepts and well as competent and timely implementation always ensure high plant availability. You will find more information on our consultation and installation services on this website under "services".
We have provided engineering, installation work and the delivery of various plants and furnaces in all sectors of the nonferrous metal industry.
