HIGH SHEAR SCREEN
The Derrick High Shear screen was developed to address the needs of the clay industry for consistent removal of grit particles in order to maintain strict quality standards. With conventional screening equipment, flat, platy minerals such as mica tend to bridge screen openings and reduce machine capacity. The High Shear screen, with its steep angle of inclination, eliminates this problem and efficiently removes platy minerals from clay slurries, even with screen openings as fine as 38 microns (400 mesh). An optional spray misting system is available.
FEATURES & BENEFITS
MACHINE DESIGN
- 304 Stainless steel construction option
- 37.5 degree machine angle with screen panel sections set at multiple downhill angles promoting thin, uniform slurry layer for positive conveyance of light and plate-like particles
- Wash water spray bar system
- Abrasion resistant bonded rubber lining option for feeder and discharge hoppers
- Abrasion resistant urethane exterior coating option for vibrating screen frame and discharge hopper lining
- Open design allows visual inspection of screen panels
TRADITIONAL CONVEX SCREEN BED
- Convex crown promotes consistent screen panel tension, increases screen panel life
- Perpendicular-to-flow screen panel tensioning allows for use of Derrick Polyweb urethane and traditional wire screen panels
- Rubber float mounts effectively isolate support frame from vibration of screen frame
- Rapid change draw bolt/draw bar assemblies provides fast and easy screen panel changes
- Derrick Polyweb urethane screens as fine as 325 mesh (45 microns) and traditional wire screens produce efficient fines removal from 40 mesh (425 microns) to 400 mesh (38 microns)
DERRICK INTEGRATED VIBRATORY MOTOR
- Zero maintenance
- E3 vibratory motor promotes positive conveyance of oversize particles
- Powerful, quiet and low energy consumption
- Greased-for-life bearings
