1. A 20 ° inclined screen is typically used for pre ­ screening and sizing applications.
2. Decreasing the inclination slows the movement across the table thereby decreasing capacity but improving efficiency.
3. Above 12 mm, dry screening is preferred.
4. Below 12 mm, wet screening using a low-pressure water spray is preferred with a water flow …
