Dynamics of fine grinding in a fluidized bed opposed jet mill

2018-3-1  In this paper, the dynamic behavior of a lab-scale fluidized bed opposed jet mill during non-stationary fine grinding is investigated in unprecedented detail. To this end, internal and external process parameters are controlled and measured as a function of the processing time in a lab-scale mill.

Dynamics of fine grinding in a fluidized bed opposed jet mill

Due to imperfect classification, particles accumulate inside the mill which is further enhanced by a high holdup of fine particles. Our results clearly show that the classification and transport processes must be studied in detail for any in-depth understanding of dry fine grinding in fluidized bed opposed jet mills.

Effects of grinding parameters on product fineness in jet ...

1998-11-1  In these cases ultra fine grinding is needed as final processing. Ultra fine grinding is a unit operation process where particles are ground to a fineness where 8t)% of the particles are smaller than 1-10 i~n. Mills often used for ultra fine grinding are the attrition mill and the jet mill [1,2].

Dry Grinding - NETZSCH Grinding Dispersing

The s-Jet ® System (patent pending) is a new innovation in a line of consistent developments being made in the area of air jet milling. Final finenesses in the submicron range (example: d 50 0.2 µm) can now be achieved with fluidized bed jet mills. As opposed to conventional dry grinding processes with fluidized bed jet mills, the s-Jet ® System uses superheated steam as its milling gas.
