Ross Expands Ribbon Blender Inventory

July 20, 2013

Charles Ross & Son Company announced that more than 80 Ribbon Blenders, sized for different working volumes and bulk densities, are now available from stock. Most standard and sanitary models can ship within two weeks or less. Built-to-order custom units are also offered with fast lead times like the 10-cu.ft. stainless steel Ribbon Blender featuring a bottom discharge extruder, lantern rings, spray bar system with atomizing nozzles, load cells and a NEMA 4X Ross SysCon Control Panel.

Ribbon Blenders are commonly used for rapid blending of dry powders, granules, pellets and other solid forms. These machines also mix paste-like materials, wet granulations and solid-liquid suspensions. Batch components are blended within a U-shaped trough via a horizontal agitator consisting of inner and outer helical ribbons. The ribbons are precisely pitched to move materials in a well balanced axial and radial flow pattern. Tightly controlled clearances between the trough surfaces and agitator tips further ensure fast and thorough mixing.

Ross Ribbon Blenders are driven by an inverter-ready gearmotor. Compared to belt- and chain-driven designs, which suffer from losses in horsepower and efficiency through slippage, direct-drive Ribbon Blenders are more reliable, delivering better performance and require less maintenance, the company stated.
