Twin 150-LC Powder Feeder

The Metco™ Twin 150-LC powder feeder is engineered from well-proven technology to precisely and consistently feed powders for laser cladding. It is the feeder choice for a number of laser cladding system manufacturers.

The Twin 150-LC powder feeder is a dual hopper feed system utilizing a volumetric feed principle and a carrier gas to transport the powder to the point of injection into the laser cladding beam. An onboard digital display simplifies parameter setup and monitors the feeder’s operation while in use.

The design and construction of the Metco Twin 150-LC powder feeder produces a consistent, repeatable and pulse-free powder flow. It can transport powders over a wide range of particle sizes and powder morphologies at feed rates of 2 to 150 g/min (0.26 to 19.8 lb/hr).

Volumetric Principle of Operation

The powder feed system is based on a rotating powder disk with an annular groove. The disk speed controls the powder feed rate, adjusted such that the powder fills the disk. A spreader bar ensures the powder does not over fill the groove. A suction bar ensures the powder is efficiently and completely exhausted into the powder feed line for conveyance by the carrier gas to the point of process injection. The powder feed rate is proportional to the rotational speed of the powder disk and can be infinitely varied to any desired value within the feed range. A PID controller precisely controls the disk speed. A stirrer in the powder hopper can be optionally used to maintain powder flow into the disk. To discharge any potential static that may build up in the feeder, the hopper is grounded.
