ROSS double cone blender delivers repeatable homogeneity for dense powders

The ROSS Model DCB-5 Double Cone Tumble Blender is a 5-cubic-foot system designed for small to mid-scale powder processing applications requiring high precision and repeatable blend quality.

The blender is engineered to process very high-density materials while delivering consistent homogeneity across batches. A large, hinged vessel cover provides sealed operation and allows access for material additions and cleaning. The double cone vessel includes a stainless-steel type 304 jacket rated for 50 pounds per square inch gauge, enabling controlled heating or cooling of the batch.

The system is powered by a direct-drive hollow-bore reducer paired with a 3-horsepower totally enclosed fan-cooled brake motor suitable for variable frequency drive operation, allowing speeds up to 24 rpm. An integrated 2-horsepower intensifier bar fitted with dual 6-inch chopper blades operates at speeds up to 1,520 rpm to support effective deagglomeration.

The vessel is rated for vacuum operation up to 29.5 inches of mercury. All product contact surfaces are constructed from stainless steel type 304 and polished to a 240-grit finish to support cleaning and sanitation requirements.

The blender is mounted on a carbon steel support frame with an A-profile design on both ends to provide stability during operation. Removable legs create 40 inches of clearance beneath the discharge, which is fitted with a 6-inch butterfly valve and Tri-Clamp outlet. An oil-lubricated rotary vane vacuum pump is mounted within the frame and connected through a rotary union to enable vacuum blending and drying.

System operation is managed through an integrated control panel featuring a 7-inch color touchscreen interface, internally mounted variable frequency drives for the blender and intensifier bar, a dedicated motor starter for the vacuum pump, safety circuitry, and a lockable main disconnect.
