Ribbon Blenders

ROSS’ Ribbon Blenders are designed to handle a wide range of dry materials and effectively coat individual solid particles, keeping long-term performance and quality in mind.

ROSS’ Ribbon Blenders are designed to handle a wide range of dry materials, from seasonings and beverage mixes to pharmaceuticals, chemicals, plastics, and agricultural powders or granules. These blenders also incorporate minor liquid components to effectively coat individual solid particles. They are manufactured with long-term performance and quality in mind.

The pictured ROSS Model 42N-18SS is crafted from type 316 stainless steel with interior surfaces polished to a 150-grit finish. With a maximum working capacity of 18 ft³, the blender is direct-driven by a 10-horsepower gearmotor for processing materials with a bulk density of up to 60 lbs/ft³.

The agitator is a solid double ribbon design, designed for center discharge, with internal flanges welded to shaft stub ends and a heavy-duty anti-friction bearing on the non-driven end. The blender includes a two-piece safety grating with half-inch diameter perforations for safe operation while the split folding covers are open. A spray bar with fan-type spray nozzles is installed on the trough via sanitary tri-clamp connections for liquid additions. The blender is operated from a four-inch color touchscreen that includes a cycle timer, start/stop, forward/reverse, and speed controls. The finished product is discharged through a pneumatically operated four-inch dust-tight knife gate valve.
