High-Volume Chip Screening and Resizing Solutions
Couple a disc screen solution with grinders, shredders, and hammermills to efficiently classify high volumes of material while increasing capacity. Easy installation, minimal space requirements, and smooth, low-speed operation make disc screens a valuable production solution.
Typical Applications
- Screening hog/boiler fuel at high volumes for biomass power plants to separate acceptable fuel size while directing screen “overs” to wood grinder/hog (see WSM Vertical Feed Grinder).
- Chip screening in pulp and paper mills/wood yards for proper sizing of wood chips and removal of over-sized material, with “overs” sent to chip re-sizer (see WSM Chip Re-Sizer).
- Gross overs removal from truck dumps to eliminate large contaminants from material flow and prevent down stream plug-ups.
- Multi-stage screening to provide three separation points including “fines”, “accepts”, and “overs”.
Standard Features
Large opening for high volume screening and chute for improved infeed
Module side sheets and covers
Heavy duty and standard duty designs available
Waterfall feature: agitating the material for more efficient screening
Key Advantages:
-
- Reduced screen size and installation cost due to highly efficient screening action.
- Easy to install and operate with low speed operation. No dynamic loads or vibrating/gyratory action that imparts forces into the support structure.
- Highly reliable operation due to simple rotating shafts with chain drive arrangement.
- Moves material efficiently and effectively – can handle high volumes and surge conditions much better than other screening machines.
- Reduced maintenance and noise due to slow operating speed and
- WSM standard screen top covers provide a fully enclosed screening device for safe and dust free operation.
The Strategic Use of Disc Screens
Using a disc screen in front of a grinder is an efficient way of maximizing grinder performance. By integrating a disc screen, only material requiring size reduction reaches the grinder. This smart separation ensures that particles already at or below target size are removed beforehand, thereby optimizing the grinding process.
