Oliver exclusively offers Westrup precleaners and fine cleaners.
The 2 Westrup cleaners have similar functions and the differences are the construction details, such as slanting of screens, single or double suction and configuration of screens.
The Pre cleaners have a larger area to remove coarse impurities ( scalping ), the fine cleaners in turn, seek to work more with minor impurities ( sifting ). We use the most rigorous rules for calculating capacity and we do not accept mediocre results.
Oliver / Westrup offers several models suitable for any capacity need. The equipment configurations take into consideration the characteristics of the client’s product, choosing the screen area and its distribution between scalping / sifting , physical space for installation and quality requirements.
The settings can be changed manually or electronically by electric motors (optional).
