Multi-shaft Mixers for the Dispersion of Ingredients

Hockmeyer offers multi-shaft mixers that include a low speed Helical or Anchor Sweep blade and an additional high speed shaft. The low speed blade feeds the high speed blade by folding and blending the mass in the vessel and enhances product uniformity by scraping the walls. The high speed blade provides high shear to dissolve or disperse ingredients. Multi-shaft mixers are often utilized to mix medium to high viscosity products.

A high speed disperser has a restricted zone of influence in viscous products, and hence the low speed blade is important to obtain a uniform mixture. When fitted with scrapers, the low speed blade helps in transferring heat to an external jacket.

Multi-shaft mixers are available in three models: dual shaft, triple shaft, and concentric shaft.
