Weigh Hopper Discharge Valve

The weigh hopper discharge valve holds the material until it is dumped into the mixing section. The cylinder is actuated by a solenoid in the valve stack on the rear 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 in an extended position, holding the dump valve closed.

When the air cylinder is actuated, the air pressure to the dump valve will be removed, causing it to open.

The air cylinder on the weigh hopper includes a spring return to allow the cylinder to retract in the absence of air pressure on the cylinder. This will cause the dump valve to open.

Caution! The pneumatic system used on the Slide Gate/Auger blender, like all pneumatic systems, is highly sensitive to oily, dirty, wet or contaminated air. If oil, dirt, water, or any other air-borne contaminates enter the system, the components could be damaged and injury to the operator could result. A proper air supply must be supplied to the blender.

When the safety circuit is disabled, the air pressure to the cylinder will drop off by shutting off all the air supply to the valve stack with the pilot operated master air valve. This will also cause the weigh hopper discharge door to open.

Mix Chamber

All of the batch blenders are equipped with an integral mix chamber. The mix chamber holds multiple batches of material so any variations in a batch are averaged over time.

Opti-Mixer™

The Opti-mixer™ is designed to provide bi-directional mixing action and can be easily taken apart for cleaning. This design is standard on all Slide Gate blenders, and is optional on all Auger models.

“HC” Mixer

The “HC” Mixer features an open wheel design and is best used for multiple regrind materials and rigid pellets. It is standard on all Auger models.

WARNING! Never reach into the mix section of the blender without disconnecting the power or air supply.

WARNING! Serious injury can result from getting your hand caught in the rotating mixer!
