Ross ribbon blenders cater to a wide range of bulk densities, suitable for industrial or sanitary applications. All units are direct driven by an inverter-ready gearmotor, an integral design superior to belt- and chain-driven blenders that suffer from losses in horsepower and efficiency through slippage. Variable frequency drives (VFDs) are usually supplied with Ross ribbon blenders for convenient soft start and agitator speed control. Ross is the world’s largest manufacturer of ribbon blenders and maintains a very robust stocking program — at present, close to 100 blenders of various sizes are available from inventory for immediate rental or purchase.
