Low noise, Low vibrations, Less clogging!

Unlike conventional vibrating screens, this roller screen is particularly useful for processing materials of "high moisture content" and "high adhesiveness."


Quiet operation

Free from operating noise and secondary pollution

Low vibrations

Vibrational load do not need to be taken into account. Compared to vibrating screens, the support frame can be designed lighter in weight and lower in vibrations.

Less likely to get clogged

Reduced concerns about clogging

Low powdering rate

Low vibration reduces the powdering rate.


Suitable to screen materials that were hard to be screened with conventional vibrating screens (such as high-moisture, -adhesion, and -temperature objects).



Used in roll grizzly feeders (for coarse screening).

1) Capacity shows the case when treating raw material with apparent specific gravity 1.6t/m³.
2) Motor output (kW) includes the efficiency of reducer, chage gear and transmission part.
3) As a rule, this machine employs variable speed operation.
4) Inclination angle is standardised as 15° downward.
5) Grizzly opening shall be set to the thickness of feed material.
