BM&M High Speed Gyratory Screening Equipment

Multi-Deck Screen High-Capacity Gyratory Screener

BM&M Screening Solutions designs and builds the industry’s best-performing, most efficient bulk material screeners. Our goal is to help our customers recover the maximum amount of usable product while removing rejects. We provide custom solutions that are tailored to your application and performance requirements. With our in-house application testing facility, we can test screening solutions using your actual material, ensuring optimum plant performance-testing and a written performance guarantee are available at no charge.

Ideal for High-Capacity Cleaning and Challenging Materials

Our Multi-Deck Screen systems have been used throughout the grain terminal industry and other markets for more than 45 years. Since the installation of our first high-capacity Multi-Deck Screen at Pacific Elevators in Vancouver, British Columbia, Canada, we have provided thousands of screening systems to customers worldwide.

The Multi-Deck Screen’s high-speed, horizontal gyratory screening motion and large element area is well-suited to high-capacity processing, and operates with little to no shrinkage. This system is ideal for high-capacity applications that require very clean accept products. Fully-enclosed construction ensures dust-free installation for a cleaner operating environment with minimal housekeeping and maintenance requirements. Product aspiration is available via optional ArrowCorp aspirators and scalper/aspirator components.

Dynamically Balanced for Maximum Vibration Control

All Multi-Deck gyratory screens are dynamically balanced. This allows them to be installed virtually anywhere in your facility, with the lowest possible installation costs and minimal motion transfer to the building itself.

Patented Drive Technology for Maximum Productivity

We align the screen drive unit with the Multi-Deck Screen’s center of gravity to achieve even screening efficiency across the entire screen element surface. With no mechanical gearbox, our patented gyratory drive can operate at speeds up to 300 RPM (nearly twice the 150-180 RPM maximum that conventional reciprocal screeners can produce). Consistent and uniform screen motion translates to exceptional efficiency and increased capacity for you high volume screening operations.

3-Year Drive Warranty

Our patented eccentric weight gyratory drive features permanent lubrication and requires little to no maintenance. Unlike reciprocating screen drives, our unique static shaft design provides torsional stiffness that ensures long, trouble-free service. All our high-speed gyratory screeners are backed by our standard 3-year drive warranty.
