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 controller.

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.

Note: If the blender is in metering mode with one of the slide gates open, do not open the front door of the blender!

Note: The safety switch shuts off the air supply to the blender. An open feeder slide gate stays open, and an overflow of the weigh hopper can occur!

Weigh Hopper

The weigh hopper on the Slide Gate/Auger blender is used to weigh each batch of material, and includes an air-operated discharge valve. After the batch is weighed and the level sensor in the lower mix section is uncovered, the valve will open and discharge the batch into the mixer with the existing blended material. The discharge valve is also provided with a quick disconnect so the weigh hopper can be removed for cleaning.

On a Slide Gate blender, the weigh hopper rests on each side on a precision cantilever load cell. To remove the weigh hopper, lift the hopper from the bottom, hold the dump door closed, and slide it out once clear of the locating tab on the bracket above the load cell.

Once the hopper has been cleaned, reposition it onto the load cell brackets, using care not to damage the load cells. Position the hopper as close to the center position between the load cells as possible.

Note: Use care when replacing the weigh hopper, since the load cells are delicate weighing instruments and can be easily damaged. Do not use force to push in the weigh hopper. If it is positioned properly, it will slide in very easily.

Note: Load cells, if damaged, will have to be sent back to the manufacturer for testing and evaluation.
