Ross offers complete mixer packages for fast and efficient dispersion of bulk solids in large batches. Pictured is a 1000-gal dual-shaft mixer with Inline Solids/Liquid Injection Manifold (SLIM) and recirculation skid. At the heart of the process is the SLIM technology that utilizes a specially engineered rotor/stator that generates a powerful vacuum for drawing solids into the mix chamber. Bulk solids are charged into the SLIM’s feed hopper while liquids are introduced into the batch mixer. The inline SLIM mixer acts like a pump and re-circulates the liquid; when the solids inlet valve is opened, the rotor draws powders into the incoming liquid stream and expels the resulting dispersion through the stator openings at high velocity. All solids are quickly injected while the liquid is relatively low viscosity. As the product thickens, the agitators in the dual-shaft mixer are engaged to incorporate minor ingredients and finish the mixture. For applications where peak viscosity is significantly high, a supplementary pump may be supplied to continue re-circulating the batch material and transport it to downstream equipment at the end of the mixing cycle.
