Pfister® DRW feeders are an industry standard for feeding pulverized coal. Precision has developed a procedure for refurbishing the key internal components – the rotor and the sealing plate. To operate at peak efficiency, these components must be flat, have parallel top and bottom surfaces, and maintain a minimum thickness.
Precision’s refurbishing program is done in two steps: assessment and rework. We begin by taking a detailed measurement of the components and checking very carefully for cracks, gouges, and generally assessing whether or not the components can be refurbished. The actual refurbishing includes detailed measurements to assure conformance to specifications.
