VIBRATING GRIZZLY SCREEN FEEDERS
Vibrating Grizzly Screen Feeders
- A Wide range of Vibrating Grizzly Screen Feeders are available to suit almost any scalping operation particularly for handling difficult and aggressive materials.
- For Sizing, grading and separation of various raw materials
- Capacities up to 2500 tonnes per hour
- Handling single particle lumps up to 2.5 m edge length
- To withstand high impact loads when installed directly under dump hopper.
- Sizes up to 3.5 m wide and 8.5 long - larger sizes available on request.
Typical applications
Include crusher relief operations handling ROM Limestone in Cement
Plants, Iron Ore crushing operations, ROM Coal in Coal handling plants,
other Mining and Quarrying applications. Another major area of application
is for screening out trash and tramp material Such as high capacity screening
of moist Coal in Power Plants without material blockage.
Increasing use in Road Building and Civil Construction Projects for screening of Basalt Rock, various types of stones and gravel.

Design and Operation
Vibrating Grizzly Screen Feeders are fully floating, linear motion
units supported on compression springs, and are driven by highly reliable
Direct Force Exciters, through drive motor and cardan shaft coupling.
Depending on design, certain models are driven by a pair of unbalance
motor exciters.
Deep side plates, connected by huck bolted cross beams, ensure high rigidity. Wear surface is provided with abrasion resistant liners.
Upon request, a separate isolation frame can be provided, for mounting the Grizzly unit, which is also spring floated and fitted with hydraulic shock absorbers to facilitate smooth start / stop without excessive resonance vibrations.
Correct adjustment of the Direct force Exciters provides optimum combination of amplitude and speed to suit each application requirement.
Oil bath lubrication ensures trouble-free operation even in hot and dusty atmosphere.
Dc electrical brake systems are offered as option to prevent occurrence of resonance vibrations during stopping operation of the unit.
Electronic Vibration Monitoring System can also be offered for on-line condition monitoring of a Grizzly unit in actual operation.
