Slide Gates Air operated slide gates are provided to meter the majority of pellet ingredients on Slide Gate blenders. • 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

Figure 6: Typical Slide Gate Assembly Each of the diamond gate air cylinders is actuated by a solenoid valve, which are controlled by the blender PLC. When the solenoid valve is energized, it opens the metering valve cylinder. When the solenoid valve is de-energized, it closes the metering valve cylinder. If the power is interrupted to the blender, the metering valves will return to the closed position, to prevent material from over-filling the weigh hopper/mix chamber. • If the blender

Figure 7: Typical Weigh Hopper Assembly The weigh hopper dump door holds the material until it is dumped into the mixing section. The cylinder is actuated by a solenoid in the valve stack on the side of the blender. In looking at the pneumatic circuit, you can see that the air regulator controls the flow of air to the valve stack. When the weigh hopper discharge cylinder solenoid valve is not electrically energized, it will provide air pressure to the air cylinder and hold the shaft
