BM&M High Speed Gyratory Screening Equipment

High Speed Gyratory Chip Classifier

BM&M Screening Solutions’ Chip Classifier provides valuable quality and maintenance feedback for any chip producer. Our Chip Classifiers use the same highly efficient gyratory action as our full size Chip Screens, allowing you to predict chip quality and avoid problems with your chip buyers.

Sorts Wood Chips by Length and Thickness

The Chip Classifier can also be used to optimize your chipper knife sharpening schedule and your screener hole sizes for reduced fiber loss.

The BM&M Chip Classifier is an affordable, lightweight, and portable unit that includes everything you need, including the exact screen size and tray thickness for your application(s). Pre-wired timer and plug-and-play design allows for easy installation and immediate use in any location.

Patented Gyratory Drive Technology

Like our gyratory screening equipment, our Chip Quality Classifier utilizes our patented, high performance gyratory drive technology. With no mechanical gearbox and permanent lubrication, the drive can operate at speeds up to 300 RPM (as opposed to the 180 RPM maximum of most reciprocating drives) for faster and more efficient operation. Our innovative drive system provides mills with reliable, quick, and accurate chip screening. Our Chip Classifier is designed to TAPPI and SCAN-CM-40:01 standards.
