Application

This series of primary impact crushers is used in the cement, aggregate and recycling industries.

For aggregate production and recycling industry, the HPI-H impact crusher is used in the pre-crushing role without a grinding path.

The single rotor primary impact crusher of the HPI-H series is used in the cement industry with grinding path, for the production of a raw material with an ideal grain size distribution for further grinding in vertical roller mills.

Equipment

The rotor can handle feed material up to 1.2 m³. The HPI-H crusher has two impact aprons and can additionally be equipped with a grinding path. The gap settings of the impact aprons grinding path can be varied by means of hydraulic cylinder, thus allowing for optimum control of the end product granulometry. Die Produktkörnung ist somit optimal einzustellen. Die Mahlbahn dient der Überkornbegrenzung.

DESCRIPTION

Avec le système HAZtronic, le concasseur peut être contrôlé et réglé à partir du panneau de commande principal. Tous les paramètres qui déterminent le produit final peuvent être saisis et appelés par simple pression d’un bouton sans interrompre le fonctionnement. Cela signifie qu’une réaction immédiate et un ajustement à des conditions de fonctionnement variables peuvent être effectués à tout moment pour assurer une productivité optimale.

Le rotor est l’élément clé du processus de concassage. Son corps ainsi que l’arbre et les paliers forment le «cœur» du concasseur à percussion.

This patented rotor is HAZEMAG’s own design and is a cast and welded steel construction, with individually cast rotor discs welded to the rotor body to accommodate the proprietary blow bars as primary crushing implements. Les battoirs sont bloqués en position dans les supports à l’aide de cales, qui peuvent être facilement retirées pour changer de battoir.

The rotor discs are welded together with rugged holding beams to provide the backbone for the blow bars. The blow bars themselves are secured to the holding beams by means of wedges, which are easily removed for blow bar changing.

The exchange or removal of the blowbars in the “QB“ rotor is assisted by the means of a blowbar lifting device; standard and supplied on all HPI-H machines. Once the wegde clamping elements have been removed, the blowbars are now ready for rotation or exchange; followed by their repositioning back into the rotor body. Due to the size and weight of the “QB“ rotor system, a rotor lock device is provided to ensure that the rotor body remains fixed into position during this procedure.

Pour la protection du corps du rotor et des battoirs, les plaques de choc se rétractent sous une charge excessive.

The impact aprons are retained in position by hydraulic cylinder, allowing adjustment and securing at the touch of a button. The instant a pre-set limiting value is overstepped in the crushing chamber, the impact apron retracts in a controlled manner. As soon as the load value returns to normal, the impact apron resumes its pre-set position, and operation continues without interruption.

The HPI-H series may optionally be fitted with a grinding path which ensures an oversize limitation. Adjusting the grinding path is effected hydraulically. Hence the product grain size may be optimally adjusted at the HAZEMAG HPI-H series.

 

In the cement industry the grinding path is the decisive assembly for reducing the oversize in the field of primary crushing. The grinding path of the HAZEMAG HPI-H series has been significantly improved: a technically mature system of hydraulics and mechanics permits the retraction in case of an overload. This patented solution increases the operational safety and availability. Thus, the potential for damage and excessive downtime due to foreign particles is greatly reduced.

Avec ce produit, HAZEMAG démontre une fois de plus sa compétence distincte sur le marché.
