PF - 700 Powder Feeder

 

PRINCIPLE OF OPERATION

The PF-700 Powder Feeder operates on the patented and proven fluidics principle, which eliminates the need for mechanically moving parts to deliver powder. Mechanically moving parts, when operated in abrasive media have a tendency to wear which in turn can result in variations in coating quality. The fluidics powder feed delivery principle provides a continuous, non-pulsating feed of powder, thereby insuring the user optimum process control and improved coating quality. An added benefit is low down- time, coupled with reduced maintenance and replacement part cost.

The system is designed so that a predetermined quantity of gas is delivered to a closed hopper containing powder. The hopper is constructed so that the gas is passed through a filter located at the bottom of the unit where it is diffused through the powder, causing the powder to become entrained in the gas and thereby become fluidized. A powder pickup tube is positioned above the fluidizing gas inlet allowing the fluidized media to be delivered under a shed on the pickup tube through a number of controlled apertures and then to a carrier area where it is propelled by the carrier gas to the feed hose.

The flow of carrier gas is monitored and controlled by the flowmeter located on the front panel of the Powder Feeder, and the fluidizing gas by the precision regulator. The delivery rate is a function of the quantity of fluidizing gas and the discharge velocity of the powder is controlled by the carrier flow. These parameters can be optimized and controlled for the specific powder being used during the coating process. The amount of fluidizing gas is controlled by the black regulator knob, located on the front of the Console.

A major innovation in powder feed technology, makes balky mechanical feeder obsolete by using gas fluidization as the metering agent. Its gas supply is initially split into two streams. One acts as the carrier and flows through a tube in the base of the hopper. The other is introduced past filters into the area where it fluidizes and conveys the powder to orifices in the pickup tube and into the carrier gas. The feed rate is proportional to the fluidizing gas flow and can be precisely controlled over a very wide range.

This revolutionary concept provides many new features and advantages for your coating operation.
