Ensure homogeneity in heavy-duty powder processes
The Model DCB-5 double-cone tumble blender (photo) has been optimized for high precision in small- to mid-scale powder-processing applications. It offers 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 brake motor, the blender is capable of 24 rpm at full speed. The double-cone vessel is rated for vacuum up to 29.5 in. Hg. The carbon-steel support frame provides 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 in. of clearance beneath the discharge point. 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-in. color touchscreen 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. — Charles Ross & Son Co., Hauppauge, N.Y.
