Jeffrey Rader, a pioneer in chip-thickness screening and processing technology since the mid-1970s, has transformed chip preparation with their equipment designed for four crucial stages: gross oversize removal, over-thick chip removal, size reduction of over-thick chips, and fines removal. This cutting-edge chip thickness screening equipment is indispensable for various materials, including bark, construction, and demolition waste, refuse derived fuel (RDF), requiring fractionation, separation, and debris elimination. The Raderwave™ Fines Screen, a standout product in their lineup, excels in fines removal while preserving valuable fiber, even in fluctuating conditions, boasting over 90% fines removal and up to 90% fiber retention. With features like a low-horsepower, variable-speed drive, and self-cleaning capabilities, Jeffrey Rader’s equipment ensures efficiency, reliability, and low maintenance, addressing common mill problems effectively.

Solution for Common Mill Problems:

Problem: Mill experiences blinding and plugging of their gyratory screen deck during winter months.
Solution: A RaderWave Fines Screen allows efficient fines screening even during wet and frozen conditions, preventing the need to bypass the gyratory screen.

Problem: Mill wants to retain pin and thin chips while minimizing fiber loss.
Solution: The RaderWave Fines Screen efficiently removes fines and grit while retaining pulpable fiber, ensuring high-quality output and cost savings when wood costs are high.
