Heavy Duty Industrial Grizzly Screens,
Made In the USA
For over 25 years, JVI has been providing electromechanical vibrating grizzly screens to customers across North America and around the world.
A Vibrating Grizzly Feeder & Screener
Grizzly screens use a series of cascading grizzly bars or “fingers” to turn over material (for more efficient screening) and separate the material by size into course “overs” that feed across the screen and fines, or “thru’s”, that fall between the fingers.
Customized to Your Application
JVI’s engineering team works closely with our customers to design custom Grizzly Screens. From grizzly bar spacing to liner materials JVI ensures each Grizzly Screens meets the heavy-duty demands of our customer’s applications.
Each Grizzly Screen is driven by two heavy duty electromechanical unbalanced motors or exciter drive gear boxes short coupled to a single AC motor. JVI Grizzly Screens can be configured to handle a wide range of applications.
Simple, Rugged – Single Mass Designs
Two of the hallmarks of JVI vibrating grizzly screens are:
- A robust design for handling abrasive products in harsh continuous applications.
- Single mass technology eliminates natural frequency tuning issues, and additional moving part, and ensures the ability to handle wet, sticky or frozen material
By engineering a simple design with the fewest moving parts possible, JVI manufactures Grizzly Screen that keep working even in the harshest industrial environments.
Capacities up to 2500 TPH
Each JVI vibrating grizzly screen is designed specifically for the application requirements, with machines available for process up to 2500 TPH
VFD for Process Flexibility
JVI vibrating grizzly screens are typically run off variable frequency drives which provide starter functions, braking functions for smooth shutdown, local keypad operation or remote interface with PLC. Additionally, the feed rate can be electronically adjusted to dial in the optimum throughput for the process and downstream equipment.
JVI vibrating grizzly screens can be supplied with CSA certification for Class II, Division I, Groups E, F & G dust explosion areas or ATEX certified unbalanced motors.
Wear Liners & Trough Covers
JVI grizzly screens are available with various types of abrasion and corrosion resistance liners. Depending on the application, JVI engineers will recommend the optimum wear liners. Some of the common offerings are heat treated mild steel, chrome carbide overlaid, UHMW, rubber, and ceramic wear liners. All are available in bolted arrangements for ease of replacement.
