The Classifier is able to achieve a precise, predictable, and extremely sharp separation at a high solids loading. The Model 100 Classifier system is ideal for the production of lab size samples, product development and/or small quantity production. The larger Model 250 and Model 500 offer precision classification at higher production rates.

Conclusions. A two-dimensional, computational fluid dynamics model based on the Euler–Lagrangian approach in the Fluent package was used to simulate gas–particle flow in a cross-flow air classifier. The model predictions for the flow field are compared with LDA measurements and good agreement is observed when using a structured grid.
