Gravimetric Batch Blenders w/Mitsubishi Control Chapter 2: Functional Description 17
Slide Gate Metering Assemblies (Slide Gate Blenders)
Air operated slide gates are provided to meter the majority of pellet ingredients on Slide Gate
blenders.
Note: The metering range assumes 1/8” diameter free-flowing plastic pellets
weighing approximately 35 lbs./cu. ft. This is meant to be an
approximate sizing recommendation and can vary with different bulk
density resins, pellet configuration, etc.
A stroke limiter (included) can be installed on the metering gates to limit their travel. This
device decreases the stroke of the gate and reduces the metering orifice of the valve. The
unique diamond gate provides a square opening at any stroke length, providing more
consistent flow from smaller valve openings than conventional slide gates. This stroke
limiter may be necessary to accurately meter low percentage ingredients.
The air cylinders operating the slide gate are rugged, stainless steel cylinders designed for
industrial use.

WARNING! Slide gates create a pinch-point hazard.
WARNING! Always disconnect and lockout all electrical power and pneumatic (i.e. compressed air)
sources prior to servicing or cleaning any blender, including all Slide Gate/Auger
models. Failure to do so may result in serious injury.
Note: The unique diamond gate provides a constant aspect
opening that remains square regardless of the stroke
length of the cylinder. This design provides a wider cross
sectional opening when approaching a closed position,
and provides better flow of plastic pellets out of the
opening.
