Protected
by the
PROTECTOR
effective protection of the separator
The foreign matter trap PROTECTOR effectively protects the separator against damage from scrap or other materials and prevents that heavy and oversized material returns to the grinding process. The trap catches all foreign material that has been discharged from the mill such as deformed or broken grinding balls.
Technical details
- Casing with two aeration units
- Two slide gates with pneumatic cylinder
- Installation in the air slide that connects the bucket elevator with the separator
- Vibrating screen in the coarse material discharge

Is the foreign matter trap maintenance intensive?
Regular maintenance and functional checks are crucial for all machines to ensure their function and to avoid unscheduled downtime. The design of our foreign matter trap PROTECTOR has been continuously improved to ensure the highest operational reliability and to keep maintenance as low as possible. The feedback from many customers about the PROTECTOR is very positive. Hence, we believe that we have one of the most reliable foreign matter traps in the market.
Can the foreign matter trap also be integrated into the air slide for rejected material behind the separator?
No, because the material defined as coarse by the separator has much less fines. As a result, the material fluidizes less, and objects would not be able to settle in the trap because they would be carried further in the conveying direction.
The name “PROTECTOR”, is because the foreign matter trap is an important protective device for modern separators, such as the QDK. The PRTOECTOR prevents that steel parts, such as grinding balls, enter the separator. If these parts hit the rotating cage, they can cause damage to the separator.
Does the PROTECTOR help to separate oversized particles in the separator fines?
Unfortunately, it is not possible to separate oversized particles with the PROTECTOR, because these are usually still smaller than 4-5mm and this grain size is the lower limit that the foreign matter trap rejects as oversize.
In open grinding circuits, without separator, a foreign matter trap is useful to separate foreign particles from the product.
