Why the Classic Screen is the Industry Leader
The Science Behind BM&M Gyratory Motion
This unique centered, high-speed gyratory motion applies higher G-force to the material bed, which eliminates blinding, maximizes throughput, and improves product quality. There are three core elements that work together to deliver these results:
- Centering the drive in the middle of the machine to generate the a gyratory motion over the entire screen surface.
- The eccentric weight drive assembly is lubricated for life. The unique static shaft design provides torsional stiffness ensuring long trouble-free service reducing ongoing machine maintenance costs.
- Increasing speed results in higher screening energy being applied to the material, eliminating blinding while also increasing throughput.
Key Benefits & Features of the Classic Screen/Chip Screen
Maximize Throughput with High-Capacity Gyratory Screening
Achieve maximum screening capacity without compromising on quality. The Classic Screen is our highest energy, high-speed gyratory model, perfect for large volume applications across the wood chip, forest, paper, and general industrial sectors. This ensures your operations run efficiently, improving overall productivity.
Superior Efficiency & Accurate Chip Classification
The unique BM&M fully gyratory motion ensures maximum yield in a highly efficient process. This superior stratification provides accurate chip length and thickness classification, which is crucial for maximizing valuable pulp fiber yield and minimizing fines, ensuring premium product quality.
Eliminate Blinding: Process Wet & Green Chips Effortlessly
Say goodbye to blinding and clogging. The aggressive, high-speed gyratory action prevents material from sticking to the screen mesh. With optional high-force ball decks, even challenging materials like wet/green chips, mulch, or rubber are processed without downtime for cleaning.

Product Options
Hanger Sling Assembly
Additional Support Option available to ensure no damage to your equipment in the event of double hanger failures.
Centralized Lubrication System
System designed to allow for greasing of the U-Joints by an operator without requiring a machine shut down period.
Over Travel Sensor
To detect when equipment is traveling outside the programmed range of motion and implement machine shutdown.
Upgraded Material for Wear Parts
A wide range of material upgrades can be provided to ensure your common wear components have a longer life span.
Zero Speed Switch
To detect when the machine has its regular operation disrupted or has reached a zero speed state.
Open Bottom Construction
Elimination of fines pan to eradicate blinding of fines material that can freeze or bond to metal in changing weather conditions.
Installation
BM&M Supplied Stand
The machine can be floor-mounted using a support stand designed for the specific machine.
Existing Structure
Because the machine suspension system has low to no vibration, the machine can be mounted directly to a structural steel framework using custom-length hangers assemblies.
