Designed to minimize risk and maximize productivity, ROSS Ribbon Blenders meet OSHA standards with safety shaft guards (no external moving parts) and limit switches that prevent operation of the agitator when any cover or manway is open. In addition, safety grating can be installed on dedicated charge ports or across the entire blender opening for extra protection and to make it easier for operators to dump bags of dry raw material into the blender.
ROSS VersaMix Multi-Shaft Mixers with Solids/Liquid Injection Manifold (SLIM) Technology enable fast and efficient large-scale powder dispersion into low-viscosity liquids including resins, oils, melted waxes, emulsions, and aqueous solutions.
A manufacturer of pest control products was previously batching a granular pesticide for insect larvae in small quantities using a table-top kitchen mixer. As the product line grew, it became necessary to move the process to a large-scale blender. The company visited the Ross Test & Development Center to see if a Ribbon Blender can produce a uniform blend of the granules, liquid component and powder.
ROSS recently designed a new skid system capable of mixing and pumping low to moderately viscous products. The Model VSL-400 design is a custom conical vessel on a movable skid with a progressive cavity pump rated for 10-30 gallons/minute.
Catalytic slurries consisting of solid catalysts and support materials suspended in a liquid medium are commonly prepared in batch tanks agitated by low-speed mixers such as propellers, anchor paddles and pitched blade impellers. These devices can sometimes suffer from long cycle times and inadequate dispersion especially in large batches. Technologies like the Ross Solids/Liquid Injection Manifold (SLIM) offer a more practical method of wetting out powders and quickly achieving the desired particle size distribution in high percent solids slurries.
