Ross has introduced the new Batch High Shear Mixer, which the company describes as an essential tool for general purpose mixing, powder wet-out, deagglomeration, dispersion, emulsification and homogenization. It features a four-blade rotor running within a close tolerance stator at variable tip speeds up to 3,000-4,000 ft/min. As the rotor continuously draws product components and expels them through the stator openings, the batch is subjected to high levels of mechanical and hydraulic shear. Interchangeable stators with different size openings provide added flexibility to adapt to a variety of applications and shear requirements.
The Ross Model HSM-130 is driven by a 30HP motor and supplied with an air/oil hydraulic lift for easy positioning and access to the mixing head. The lift also allows users to conveniently utilize multiple tanks and accommodate a range of batch sizes. If preferred, the shaft length can be customized as well.
An adjustable downthrust propeller enhances circulation and eliminates floating solids. A modified rotor/stator assembly capable of sub-surface powder injection is offered for processing difficult-to-disperse powders that tend to dust or form tough agglomerates upon contact with liquid. This option, called the Solids/Liquid Injection Manifold (SLIM), is also available on Ross High Shear Mixers designed for inline/continuous operation.
Standard and sanitary models range from 3/4 to 100 HP, in both atmospheric and vacuum/pressure designs.
