The TSP and TTSP toner classifiers were developed especially for dedusting toner. The demands made of the end-product quality in toner processing are so high that particle counters (Coulter Counter) are employed for the quality control. Specification of the dedusted coarse material is given in number%, whereby the specification generally permits 3-10 number% < 5 µm. The focus of attention during development was a maximum precision of cut, although other aspects such as handling and safety as well as operating and installation costs were also taken into account.
- One- or two-stage ultrafine classifier with a high precision of cut for optimum coarse products
- Specially designed for classifying toner and pigments, e.g. minimisation of the ultrafine portion <2 - 5 µm
- Hinge-back housing makes the machine easy to clean when changing the product
- Classifying wheel(s) arranged vertically
