The Wirtgen-owned crushing and screening plant manufacturer says that cone crushers are mainly used in hard stone, impact crushers in soft to medium-hard stone and in recycling, and a very high product quality is expected from both plant types.
Kleemann adds that, thanks to the new optional double-deck post screening unit, it is now also possible to produce two classified final grain sizes, with a single machine and without the use of an additional screening plant.
The large screening surface makes effective screening possible even for grain sizes below 20mm. The discharge height of the fine grain conveyor is designed for a maximum stockpile volume, and oversize grain can be processed in a closed material circuit via a return conveyor. As an option, the conveyor can be swivelled hydraulically by up to 100°, which also makes side discharge possible. A kidney-shaped stockpile can thus be created manually.
Kleemann says that, if an application is only to produce one classified final grain size, the post screening unit can simply be used as a single-deck version.
It adds that, s the MOBIREX MR 110(i) EVO2 is frequently used in recycling applications, wind sifters are used here as an option. They guarantee increased material quality because contamination through lightweight material (e.g. wood and plastic) is removed from the material. The air flow can then be controlled precisely depending on the material, which also reduces manual and sorting work. The wind sifter can only be used in conjunction with the post screening unit. With the double-deck post screening unit, a second wind sifter can be used as an option for cleaning the medium grain.
