It looks like a question and an installation description in one sentence, although there is no question mark at the end.

A Dutch saying is (free translated): I can't make chocolate out of it.

Then what?

Your cryptical post cannot generate answers.

Try again with a better description of the installation and a specific question.

Sry sir i will try best to explore my questions.

Application-air classifier Mill to achieve fine grinding.

principle-an air classifier mill applies impact grinding and classification in one step. the mill uses airflow to convey feed material to the grinding chamber, classifies the material into fine and coarse fractions, recirculates the coarse fraction for further grinding and conveys fine particle out of the mill ,all in one continuous operation.

Problem-Now we talking about higher air classifier mill which have 200 hp main motor.

when these mill starts, rotor & classifier of mills start rotating which generate airflow which we call its aspiration volume.

air classifier mill connected to bag filter with ducting to separate air and fine particles.

Now mill aspiration volume is high suppose 12000 m3/hr.

Grinding capacity is only 500 kg/hr we select fan for these application 18000 m3/hr Due to higher flow rate bag filter size is also big even low filter load.

fineness of these particles after grinding is only 10 micron which we difficult to catch.

Question-Is there any other way to separation of fine particles & air ?

How we choose air flow for these type of application?
