The ultrafine classifier TTD is second to none when it comes to classifying soft to medium-hard minerals at high throughputs, for example in the production of fillers. The patented classifying wheel geometry of the Turbo Twin permits high throughput rates and loading factors at high fineness values of up to d97 = 3.0 μm. Due to the low pressure drop of the TTD, this machine is characterised by its high energy efficiency. Savings of up to 25 % are possible.
The classifying wheel is supported in bearings on both sides and permits extremely high peripheral speeds of up to 120 m/s. Another unique feature is the optimised product routing direct to the classifying wheel. This prevents any backmixing with the already classified coarse material. It is no longer necessary to adjust the classifying wheel gap, which simplifies maintenance tremendously. There are currently six machine sizes available: 200, 315, 500, 630, 800 and 1,000.
