Case History: Volumetric Feeders Provide Fluidized Bed Coating Line with Accuracy

From Acrison, Inc.
 

 
Anchor Fence, located in Baltimore, is a producer of industrial chain link fence. To manufacture its product, the company uses a proprietary fluidized bed coating process that permanently bonds PVC vinyl powder to galvanized steel fence wire. After the wire is coated, Anchor weaves it into the wire fabric that is used in its various fence designs. The process, developed by Anchor in the 1960s, requires that the powder be precisely metered into the fluidized bed. Precise metering ensures that the coating is uniform and is without holes and voids. The success of the coating operation depends in large part on the accuracy of the feeding process. Because the feeder is such a critical component of its operation, Anchor evaluated its production needs and operating conditions deliberately before beginning to solicit bids from feeder manufacturers. As a result of its evaluation, the company decided that in addition to providing feed accuracy, the volumetric feeder it purchased would have to be able to run essentially unattended for two shifts a day. The company then established other criteria that it used in selecting a dry solids feeder:
