Dynamic Air Classifiers
CTC Series
Classification in new dimensions
The CTC fine classifier series is based on the latest findings (fourth generation) in the field of classification technology. This series has been designed to optimize production, operating, and maintenance costs, which was achieved by combining rotor geometry and an improved flow design in a new way. This leads to more efficient classification, low bypass of fines, and therefore lower energy consumption for pulverization and classification.
The CEMTEC CTC classifiers are designed specifically for cement and use with other materials with a similar range of fineness.
The classifier’s modular design enables CEMTEC to create excellent customized solutions for their ball mills and tower mills.

Fine particle discharge: Top
Drive unit: Located above the classifier
Material feed: From below with air flow
Fine particle discharge: Below
Drive unit: Top
Material feed: From above
Air flow: "Air-swept"
Process design of CTC classifiers
The process design is geared to production and product requirements. The discharge temperature of the fines can be optimally set or adjusted for downstream process steps by appropriate configuration of the air circulation. CTC classifiers can thus be operated in an open or closed/semi-closed circuit.
The newly developed CTC series for cement and coarse filters distinguishes itself by its extremely high yield of fines and low levels of screen residue. This results in additional optimization of the specific production and investment costs, along with an indirect reduction of the specific grinding energy. With optimized configuration and the corresponding grinding conditioning the bypass of the fines portion can be below 5%.
