Heavy duty linear/elliptic motion, Grizzly Screen ROL®

It is used on primary pre-screening stations before fragmentation.

It is a very robust inclined screen equipped with diverging bars or perforated sheets mounted in cascade to tilt the blocks.
The ROL type mechanism allows rapid adjustment of the vibration amplitude .

Scalping screen for all primary station classification applications . Allows pre-screening before crushing as well as the removal of finest, dirtiest, and earth- or clay-laden materials. It combines high unit output, low maintenance , and economical operating costs.

Highlights

• The vibrating part or “carcass” is based on a fixed frame by the mean of elastic suspensions isolating the carcass while leaving it oscillate.

• The vibrator mechanism has 1 to 4 high speed turning shafts. Each-turn, these shafts cause a shock produced by the centrifugal force developed by counterweights.

⇒ These repeated shocks transmitted to the frame and screen cloths, create a circular vibration that operates the sorting depending on the screen mesh. The vibration is evenly distributed over the whole screening surface thus ensuring optimim efficiency at any point.
