Ribbon Blenders for Specialty ApplicationsS. Himmelstein | May 26, 2017
Ribbon blenders from Charles Ross and Son Company allow a wide range of customization and are suitable for mixing powders, granules and other dry solids, as well as wet applications including suspensions, slurries and pastes. Provisions for vacuum and internal pressure, temperature control, sanitary construction, special requirements for charging and discharging, handling of high density, friable or abrasive materials, spray system for liquid additions, load cells and automated recipe controls are some of the optional features routinely offered.
The Ross Model 42N-36S Sanitary Ribbon Blender has a 36-cubic feet maximum working capacity. Driven by a 25 horsepower inverter-duty gearmotor, the precisely fabricated double ribbon agitator turns to up to 40 revolutions per minute within the U-shaped trough, producing a balanced lateral and radial movement of batch materials. Wetted parts are stainless steel 316-polished to 150-grit for ease of cleaning.
The blender cover includes safety grating and a custom bag dump station. A 150-pounds per square inch gauge, American Society of Mechanical Engineers (ASME) code stamped dimpled stainless steel jacket is supplied around the trough for heating/cooling. Multiple spray bars and nozzles deliver liquid raw materials and clean-in-place (CIP) solution. A NEMA 4X Operator Control Panel is pre-wired to the blender and factory tested.
