Pulveriseringskværn med højtydende sorteringssystem

A high performance classifier system for use in a pulverizer mill (e.g., a mill used to crush large coal particles into small particles) includes a cylindrical extension member (5) with a roughened interior surface. Other preferred features include a converging/diverging orifice provided by an inter...

Zusammenfassung:	A high performance classifier system for use in a pulverizer mill (e.g., a mill used to crush large coal particles into small particles) includes a cylindrical extension member (5) with a roughened interior surface. Other preferred features include a converging/diverging orifice provided by an intermediate classification liner (3) on the interior surface of the mill body, curved classifier vanes (4) at the upper end of the classifier, and tilted vanes (2) between the mill housing and the upper end of the classifier. Improvements in efficiency of particle separation are achieved.
