A Powder Feeder is created specifically for thermal spray coatings Due to its tiny size, it can be transported to a job site to be used as a portable powder feeder. Exceptionally precise and reproducible feed rates are controlled for the device. Users may quickly remove extra powder and clean the inside of the powder hopper (canister) thanks to the hinged plate that the canister is fixed on. Clearing extra material from the spray system is made simple by separate controls for the powder feed and carrier gas. Any gun can be equipped with a switch for remote operation.
A system that can store powder and feed it in a regulated manner is the Portable Powder Feeder type PF. A base unit that carries the hopper and a feeder unit (hopper) make up the bulk of the powder feeder. Inside the base unit are the hopper driving unit and the Siemens S7 PLC controller. The hopper is a standalone module that can be customised using several types of base units. With the help of these fundamental units, one, two, three, or four hoppers can be controlled uniformly. In accordance with customer needs, specially customised cabinets can also be offered.
All currently available thermal spray gun systems on the market can accommodate up to 6 separate powder feeders. Hoppers for plasma or HVOF gun applications come in a variety of models with capacities of 5L or 1.5L.
A constant volumetric feed principle governs how the feeder functions. A powder carrier disc with a slotted wheel set off-center in relation to the canister is located at the base of the pressurised canister. Each slot may hold a specific amount of powder, which is supplied into the powder hose and later into the spray gun such as thermal spray gun, flame spray gun, arc spray gun, powder flame spray gun and metalizing gun by an inert carrier gas such nitrogen as the disc rotates through the exit port. The powder disc rpm, which is controllable from the front panel, is directly proportional to the powder feed rate.
The container is gently pressurised (at a maximum of 3.5 bar/50 psi or up to 15 bar/214 psi upon request) during the operation of the powder feeder. Only the gas may leave the hopper after being drawn in by the suction device, and the gas flow amount can be used to change the powder particles' exit velocity. However, depending on the powder in issue, a minimum volume of gas must flow through the hopper to guarantee a pulsation-free and continuous feed.
The powder feeders can also be ordered with a variety of spreader/suction unit sets, including custom units, spreader/suction unit sets for liquid (powder that flows well), non-liquid (powder that flows poorly or not at all), and L for liquid powder. Different groove depths, widths, and spreader/suction units are available for the feed discs. With the help of these many settings, customers can benefit from a wide range of powder feeding rates (from 0.1 g/min to around 300 g/min) with an incredibly high feed accuracy (+1% in comparison to the maximum feed rate). Additionally, a variety of materials and surface finishes are offered for the discs.
