ROSS Model 42N-18 is designed for efficient atmospheric blending of free-flowing materials. The blender has a maximum working capacity of 18 ft3 with a 22 ft3 full holding capacity.

A solid double ribbon agitator, powered by a 7.5 HP TEFC motor, delivers thorough blending at speeds up to approximately 47 rpm with variable speed control down to 5 rpm. Designed for center discharge, the agitator is supported by heavy-duty anti-friction bearings and fitted with two-piece stainless steel stuffing boxes featuring adjustable and replaceable braided Teflon® packing, providing reliable sealing and simplified maintenance.

Fabricated from Type 304 stainless steel with an 80-grit interior finish, the mixing trough includes a two-piece hinged cover with quick disconnect pin hinges, FDA-compliant silicone gasket, and NEMA 12 safety interlock switches for dust-tight operation and safe access during cleaning and maintenance.

To support dispersion of minor ingredients and reduce agglomerates, this blender is equipped with a high-speed stainless-steel chopper mounted on the top sidewall at a 45-degree angle. The four bladed chopper operates at speeds up to 1,800 rpm and is powered by a 5 HP TEFC motor to ensure efficient dispersion and improved batch consistency.

A pneumatically operated 4" dust-tight knife gate valve enables controlled discharge and simplified clean-out, while support legs provide 48” clearance beneath the discharge valve for downstream material handling. A load cell system rated for 4,000 lbs. supports accurate batch weighing and process monitoring. Operator controls include start/stop functionality, variable speed adjustment, forward/reverse operation, and digital monitoring of speed and motor load for each agitator, along with two handed pushbutton controls for the discharge valve.
