The STATORMIX core sand mixer has two mixing chambers, which are separated by a row of stator bars. Each mixing chamber is equipped with a specially shaped rotor blade mounted on, and driven by, a common shaft.
As the rotating blades force the sand back and forth from one mixing chamber, across the stators, into the other mixing chamber, the sand is slowed down every time it passes the stators and then speeds up again, causing division of flow and remixing several times per second. This controlled, forceful movement of the sand across the stators causes the highly efficient and intense mixing of the injected binder with the sand.
The hinged mixer front cover can be opened and moved to the side, making the complete mixing drum freely accessible. The mixing tools can be removed after releasing a bolt. Once removed, they can be easily cleaned outside of the mixer such as in a blasting chamber.
After the mixing cycle is finished, the sand is completely discharged from the mixer. Almost no sand remains in the mixing drum. Different batches of sand can thus be treated in sequence without cross contamination.
