ContiClass®System
ENGINEERING DOBERSEK GmbH delivers separation plants for separation and classification of solid materials for various applications. The ContiClass®System patented by ENGINEERING DOBERSEK GmbH provides continuous classification of ores. An essential precondition for perfect separation is constant pressure at the hydrocyclone inlet. The ContiClass®System is designed to enable pressure variations to be counterbalanced by a speed-controlled pump. As an additional effect the pump lifetime is extended tenfold, because, amongst further positive effects, cavitation is avoided.
A regular problem in ore treatment plants is that constant ore feed cannot be guaranteed. In order to counteract feed variations, mills and pumps have to be switched on and off. This is not necessary for those plants equipped with the ContiClass®System delivered by ENGINEERING DOBERSEK GmbH.
Separation plants are mainly used for non-ferrous, precious and heavy metal extraction. To digest extracted ore, e. g. nickel or copper, the ore is ground in ore mills and mixed with water in order to achieve a pumpable suspension. For perfect digestion of the contained metal a particular grain size is necessary. However, after grinding the grinding the ore grain sizes vary strongly and cannot be easily altered.
The ContiClass®System solution for a profit-increased extraction of non-ferrous, precious and heavy metals (like copper, nickel, zinc, gold) as well as of mineral ore (phosphates) is increasingly used by our customers. Other possible applications are mine refilling, silica sand extraction and coal treatment.
