A RakeMax® HF é uma peneira com barras em L e, como a RakeMax®, pertence à família MAX de peneiras HUBER.
Essa tela tem uma seção inferior plana e, portanto, hidraulicamente vantajosa que passa para uma seção de transporte inclinada. Isso combina os benefícios do comprovado RakeMax®, separação de sólidos confiável e alta capacidade de descarga de crivos, com uma baixa perda de peso devido a uma grande superfície de crivo eficaz.

The HUBER RakeMax® HF Multi-Rake Bar Screen is the ‘high flow’ version and further development of the successful HUBER RakeMax® Multi-Rake Bar Screen that is well-proven in thousands of installations.
The RakeMax® HF screen consists of two different sections: The flat bottom section provides a large screening surface and favourable hydraulic conditions, the steep conveying section ensures screening on a small footprint. Material removal starts virtually right at the bar rack mounted flat to the channel bottom so that any accumulation of disturbing material is eliminated.
The optimal approaching flow conditions and large effective bar rack surface ensure a high hydraulic throughput capacity. The cleaning elements, attached to the chain system, can easily be adjusted to different requirements so that a highly variable screenings discharge capacity is achieved. This is especially favourable for high solids loads. Depending on the size of bar spacing, the bar rack design is either a flow-optimising bar or non-blocking wedge wire profile.
Both ends of the cleaning elements are connected to drive chains. Each chain is driven by a sprocket on a common shaft and a flange mounted gear motor. At the end of the bar rack cleaning cycle the cleaning elements are cleaned by a pivoted comb that reliably discharges the removed screenings into a downstream transport, washing or disposal unit. The easy to access and maintain drive unit is installed above the channel. Due to the screen’s compact design its height above floor is very low.
The innovative HUBER Detection System Safety Vision enables the screen to "see" the screenings and reliably identify potentially critical contaminants.
This effective protection mechanism reliably prevents damage to the screen or the downstream equipment, which not only increases the availability of the machines involved, but also improves the operational safety of the entire plant technology. In addition, the adaptive operation based on event detection means that the machine can always be optimally utilised and the running time of downstream machines can be optimised according to the actually necessary demand.
