How They Work

Gyratory Technology

The unique technology developed by BM&M creates an unbeatable combination of motion and speed that generates higher volumes and greater efficiencies. There are 3 core elements that work together to deliver these results.

Centering the drive in the middle of the machine generates a gyratory motion over the entire screen surface.

A stationary and maintenance-free drive with stabilized shaft allows for higher speeds (300 rpm) than the competition (180 rpm).

Increasing speed results in higher screening energy being applied to the material, eliminating blinding while also increasing throughput.

All combined, the BM&M technology achieves material fluidization and maximizes contact time with the screen mesh, resulting in the most efficient separation.

DRAG LINK

SLIDE BEARINGS

Outlet and inlet connection

Rotex customizes each machine configuration to match the exact application needs. Connection options range from rubber to sanitary BFM connections to nutating connections. Ask your rep which is right for you.

COMPENSATING CLAMPS

Patented adjustable clamps ensure uniform sealing of cover and screen decks. The screens are attached using Rotex tensioning clips, which automatically draw the correct tension on the screen clothing.

Outlet and inlet connection

Inspection ports

When the machine is stopped, you can easily remove the inspection cap and ensure the screener is operating correctly. This could include inspections for screen blinding, screen tears or material buildup.

Drag link

The drag link converts the gyratory motion created by the drive head to reciprocating motion for precise, near-size separation.

Slide Bearings

Only sliding friction is generated with our slide bearings, ensuring they are lightweight and have a long operating life while introducing minimal vibrations or noise.

Sliding inlet

The sliding inlet eliminates the hassle associated with flexible connections. Say good-bye to torn flexible connections, and improve plant safety. A Teflon™ wear ring and close running flange to allow for movement of the machine.

DRIVE

A simple reactionary drive cartridge incorporating two spherical roller bearings provides years of longevity.

Universal joints

Universal joints accommodate the torsional forces created by the unique Rotex Gyratory Reciprocating Motion while bearing the entire weight of the machine. In addition, 500 to 1,000 pounds of abrasion-resistant liners ensure your machine will withstand any application.

EASY ACCESS DOORS

Customized heavy-duty DESTACO door clamps allow quick and easy screen access.

BRUSH DISCHARGE

Using brush discharge connections eliminates the challenges caused by flexible outlet connections, including reducing dust, containing separated product fractions, and increasing the life of the machine by up to 10x.

How They Work

Gyratory Reciprocating Motion

The Gyratory Reciprocating Motion gradually transitions along the length of the machine, starting off as purely gyratory motion at the head, then moving to elliptical movement in the center and reverting back to reciprocating toward the end.

Circular Motion

Elliptical Motion

Reciprocating Motion

Circular motion is used at the feed end to spread materials across the full width of the screen surface. Once stratified, the materials are aggressively conveyed forward.

Long-stroke elliptical action enhances the product stratification and conveys materials at high capacity.

Reciprocating motion at the discharge end removes near-size particles, improves screening efficiency and ensures material is in constant contact with the screen surface.
