Operator Responsibility The operator’s responsibility does not end with efficient production. The operator usually has the most daily contact with the equipment and intimately knows its capabilities and limitations. Plant and personnel safety is sometimes forgotten in the desire to meet incentive rates, or through a casual attitude toward machinery formed over a period of months or years. Your employer probably has established a set of safety rules in your workplace. Those rules, this ma

Slide Gate Metering Assemblies (Slide Gate Blenders) Air operated slide gates are provided to meter the majority of pellet ingredients on Slide Gate blenders. 1 Note: The metering range assumes /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

Each of the diamond gate air cylinders is actuated by a solenoid valve, which are controlled by the blender. 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 slid

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

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 ex
