G-MTK 130 Mobile Tertiary Crusher

In this footage the G-MTK 130 mobile tertiary crusher is seen working on its own legs on its trailer chassis; the layout makes clear that the machine can be towed to site and brought into production in a short time.

In the images the intermediate product discharged into the feed hopper descends from the feeder to the mouth of the rotor; the material accelerating inside the crusher body strikes the impact plates and falls onto the lower conveyor as a finer flow, something that can be read even from the dust cloud at the discharge point. The screen and the return belt on the chassis are also in the same frame.

The critical point here is the effect of rotor speed on the product curve.

The tertiary stage is the last link of the crushing chain, and it is this stage that determines cubical, low-flakiness fine material. The continuous running of the return belt in the video shows that the coarse grain remaining on the screen is sent back to the rotor, that is, the line forms a closed circuit within itself. This circuit is the real mechanism that raises the share of the desired fraction.

Thanks to the mobile chassis the same unit can be moved from quarry to quarry and added to the end of an existing line. For those seeking a solution integrated into a stationary plant, the GNR Series Tertiary Crusher options share the same crushing principle.
