Scalping and Screening in one unit. FG Series grizzly feeders provide consistent flow rate under a variety of loading and material conditions finding applications in quarries, sand & gravel, mining and recycling applications.
FG SERIES GRIZZLY FEEDERS
Nesans FG Series Grizzly feeder is designed to combine scalping and Feeding in one operation. Furthermore, they are tailored to provide a continuous, consistent, uniform flow of materials from the hopper to the crusher. Installed ahead of a primary or a secondary crusher, larger pieces are scalped into the crusher while undersize materials are passed into the grizzly bars, bypassing and relieving the load to the crusher. Thus the use of FG Series Feeders increases crusher capacity and all round efficiency.
Nesans FG Series Grizzly Feeder is a heavy-duty, low horsepower choice for efficient screening and feeding of aggregate materials. Our energy-efficient, two-mass vibratory feeder design is proven in hundreds of mining, ore, and mineral applications. Multiple sizing decks (on a single unit), explosion-proof motors and Variable Frequency drives are important high-performance options. In contrast to conventional drive shaft – pulley based feeders used for primary feeding purpose, Vibro motors based Grizzly Feeders avoid daily lubrication menaces which most of the crusher operators fail to perform in a routine basis. Consequently, over all down time is reduced and plant up time is increased up to four fold times.
• Two-Mass, sub-resonant natural frequency self-compensating design automatically adjusts to material head load and weight changes, maintaining constant feed rate regardless of load.
• Standard and custom engineered sizes available.
• Available in optional specialty finishes and construction materials.
ADVANTAGES AND BENEFITS
• Built for long life and high reliability
• No moving parts that could wear and require replacement, assuring trouble-free service in all types of environments
Grizzly bars are not standardised and can be modified as per the customer's requirement. The grizzlies will vary depending upon the application, feed size and feed characteristics.
Can grizzlies be used in secondary crushing ?
Grizzly feeders are used but not limited to the primary crusher for scalping the soil that may come along with the feed. They can be installed anywhere, where there is a need for the rock to be crushed consists of soil and clayey components.
Can we introduce water into the grizzly feeder ?
Introducing water into the grizzly feeder allows for a quick separation of soil that may stick upon the rocks. Though, the moisture content of the feed should be kept under control from altering the crushing process.
What is the speed of the grizzly feeder ?
The stroke and speed of the grizzly feeder depends upon the application. Generally grizzlies feeding jaw crushers are run slow and those feeding impact crushers are operated fasted to match the capacity.
