The ultra fine classifier TTD (TURBO TWIN DOUBLE) is second to none when it comes to classifying soft to medium-hard minerals at high throughput. The wheel geometry of the Turbo Twin permits high throughput rates and loading factors at high fineness values of up to d97 = 6.0 μm.
The classifying wheel is supported in bearings on both sides and permits extremely high peripheral speeds. Another unique feature is the optimized product routing direct to the classifying wheel. This prevents any back mixing with the already classified coarse material. It is no longer necessary to adjust the classifying wheel gap, which simplifies maintenance tremendously.
