Features

High screw rpm
The VT660 features a high screw rpm, which optimizes mixing speed and allows for thorough cleanout of various ingredients.

Screw design
All Vermeer twin-screw vertical mixers are a testament to logical, practical engineering. Two overlapping screws and offset baffles on the tub wall help to achieve a consistent, thorough mix. Instead of feedstuffs remaining in either the front or the back of the tub, the construction of the tub and screws encourages the material to travel between the screws in a clockwise motion.

Efficient cleanout
Three points of contact with the tub floor, made up of two bi-pulse legs and the leading edge of the screw, help move material from the tub to the discharge conveyor for consistent distribution along a bunk line or tire.

2-speed gearbox
The standard 2-speed gearbox is designed to relieve horsepower demand while mixing heavy rations. Use the low speed (26 rpm) at the start of the mix and use the high speed (39 rpm) for more complete cleanout.

Low loading height
At just 105 in (267 cm), the VT660 twin-screw vertical mixer has the lowest loading height of all Vermeer vertical mixers. The low loading height provides versatility among different operations during loading, feeding and storage in situations where clearance restrictions may be present.

4-point scale with Bluetooth connectivity
A 4-point scale helps operators be confident in load weights. Optimize rations and achieve defined targets when feeding in multiple pens. Plus, Bluetooth connectivity makes load weights accessible from a smart device.
