VG Series™ scalping screens, or grizzly scalpers as they are also called, are utilized in the primary crushing stage. They scalp the primary feed allowing fines to bypass the primary crusher. Screening the fines before the crusher results in higher overall capacity of the primary crushing stage.
Capacity
High G force. Adjustable stroke. Perfect match with primary crushers.
Availability
Robust fully huck-bolted design. Easy maintenance. Options to meet special needs.
Diverse applications
For stationary, portable and mobile applications. Surface and underground. Abrasive rock, soft rock, gravel, recycling, industrial materials, slag.
Expert support
Over 1,500 field service experts and 40+ service centers globally.
High scalping efficiency, more tonnage
Metso VG Series™ primary scalping screens have been designed for the toughest applications, high capacity and the ability to process abrasive material, either in stationary or mobile crushing plants.
Maximizing the efficiency of the primary crushing stage across a wide variation of applications, VG Series™ grizzly scalpers are most often used with push feeders, apron feeders or vibrating pan feeders.
Ideal applications
- Any kind of scalping application
- Stationary, portable and mobile applications
- Surface and underground applications
- Abrasive rock, soft rock, gravel, recycling, industrial materials, slag
Ideal operations
- Quarries
- Gravel pits
- Mines
- Crushing and screening contractors
Beneficial features
The speed and stroke are easily adjustable, ensuring optimal feed control of the primary crusher. The long stroke capability enables better scalping efficiency, delivering a linear motion with high G force (5.5 G).
VG Series™ scalping screens are slightly inclined at 5° to reduce blinding when feed is sticky and contains fines (increased capacity). They can be fitted with various grizzly bar options to allow wide separation flexibility.
The vibrator beam is weld-free and fully huck-bolted for optimal, robust performance. The vibrator and cardan shaft design, in turn, ensure a more reliable operation than a direct belt-drive design.
