The revolutionary TDC Chalkmaster is used to apply talc or powder to the wire, cable, and other stranded materials during the manufacturing process. Its simple and durable design lends itself well to a long product lifespan. TDC’s Powdermaster adds the convenience of flip-top loading for ease of product threading and powder capacity is also expanded.

The heart of the system is the special patented design of the powder applicator. Except for the self-cleaning rotary filter, there are no moving parts in direct contact with the powder. The filter bearings and drive are external and are not affected by powder. The patented rotating system is self-cleaning.

CHALKMASTER is an effective method of applying talcum and SAP powders to cables on a production line. The quiet operation and reduction of powder in the atmosphere have made it a well-proven method of meeting improved health and safety standards. Over 300 units are in operation throughout the world, handling powder applications in many diverse environments.

The basis of the design concept is the creation of an effective fluidized bed of powder by passing compressed air through a micro-porous ceramic tile, via a regulator and filter. The powder is then accelerated up the twin applicator tubes and is directed onto the product which passes continuously through the machine. The powder is pumped continuously through the applicator tubes, while air is extracted by a powerful vacuum motor, through a self-cleaning rotating filter.

A negative pressure is produced within the machine, which creates an air intake at the input and exit ports; this stops powder escape into the workplace. Powder deposition is controlled by an air-wipe system which provides a simple effective method of applying standard talcum powders in a continuous production line.
