CHARLES ROSS & SON CO.: Tumble Blender
A practical choice for small to mid-scale powder processing, the ROSS 5-cu. ft. Double Cone Tumble Blender Model DCB-5 is optimized for high-precision processes, offering the durability needed to handle very high-density materials while also delivering repeatable homogeneity and powder blending properties.
A large, hinged vessel cover provides proper sealing and sufficient access for additions and cleaning. The vessel includes a stainless-steel type 304 jacket rated for 50 PSIG, for heating or cooling the batch. Powered by a direct-drive hollow-bore reducer and 3 HP TEFC brake motor suitable for VFD operation, the blender is capable of 24 rpm at full speed. A 2 HP intensifier bar with dual 6" chopper blades turn up to 1,520 rpm for effective deagglomeration.
The double cone vessel is rated for vacuum up to 29.5” Hg. Stainless steel type 304 product contact parts are polished to a 240-grit finish for easy cleaning.
The carbon steel support frame features an A-profile on both ends, providing a wide, stable base for safe distribution of the forces associated with the rotating mass, with pad plates for mounting and integrated guardrails. Removable legs provide 40" of clearance beneath the discharge point. Material is discharged through a 6" butterfly valve with a Tri-Clamp outlet.
An oil-lubricated rotary vane vacuum pump mounted inside the support frame and plumbed to the blender via a rotary union, which allows for convenient vacuum blending and drying. All functions are managed through a control panel with a 7" color touch screen user interface, internally mounted VFDs for the blender and intensifier bar, a dedicated motor starter for the vacuum pump, safety circuitry, and a lockable main disconnect.
