The AP Over Belt Aerator unit bases its working on a well established concept. It offers innovative characteristics which make it up to date and efficient, ensuring the perfect aeration of molding sand as required by the most recent molding machines.

The AP is exceptionally effective in improving green sand quality after preparation by the mixer. Thanks to its homogenous aeration characteristics, it is possible to improve sand quality and eliminate lumps.

The machine incorporates three powered rotors, lined-up and closed in the protective hood. The central rotor is of the finger type while the other two are of chevron type. The machine is installed in-line over a flat belt conveyor. The height of the rotors to the belt is adjustable as required by the user.he three rotors rotate at a moderate speed in the sand path. Sand entering the unit is lifted by the first rotor and hurled through the pins of the second rotor, obtaining the first elimination of possible lumps and aeration.

After that the third rotor gathers and again throws the sand against a curtain made of resistant rubber, cut in vertical stripes to form a comb where possible residual small lumps are finally disintegrated.

The wear resistant blades and fingers are protected by tungsten carbide hard facing and bolted on the cage rotors in a way to be easily removed for maintenance when necessary.

This unit enjoys a longer operating life more than other similar machines working on the same concept. Furthermore, our 'hard facing' know-how ensures and important decrease in user maintenance costs. For example, the rotors are mounted on alloyed steel shafts fixed with Bikon couplings.

Robust cast iron bearing supports have double line rollers, over engineered in order to ensure an extremely long working life.

All external driving parts are properly protected to avoid any accident hazard.

Inductive rotation sensors advise of any possible drive failure and/or slowdown due to possible overloading, activating an alarm for the best protection of the system.
