The Alpine TTD Ultra-fine Air Classifier is a high performance particle separator ideal for classification of soft to medium-hard minerals at high throughputs, such as industrial fillers. The classifying wheel has a new patented design for high throughput rates and loading factors at high fineness values of up to d97 = 3.0 μm. Due to the low pressure drop, the Alpine TTD Ultra-fine Air Classifier is considered one of Hosokawa’s most energy efficient air classifiers.
The classifying wheel has support bearings on both sides and permits extremely high peripheral speeds of up to 120 m/s. Another unique feature is the optimized product routing to the classifying wheel which prevents back mixing with the already classified coarse material. There are six models available for pilot classification systems up to large production units.
