KEY POINTS : WHY TO CHOOSE BALAJI'S PLANETARY MIXER ?
MIXING BLADES

To maximize both blade life and mixing efficiency, the angle of attack is optimized in a way that promotes pushing rather than slicing. Additionally, the outer edges are thickened to ensure even wear distribution.

USE OF NI HARD MATERIAL

The consistency of NI-HARD material's rigidity, remains constant across all sections and layers. Consequently, there is no fluctuation in abrasion rates as the plates gradually wear out. Depending on the type and volume of aggregates used, the Ni-Hard wear parts can have a lifespan of up to 5,000 m³.

SPACIOUS MAINENANCE DOORS

To ensure operator safety, our planetary mixer incorporates spacious maintenance doors that allow for convenient inspection and maintenance, thereby minimizing potential safety risks. These maintenance doors are thoughtfully equipped with a safety switch that automatically shuts off the main power upon opening ( This feture is optional as per requirment only).
