Technical parameter
Air volume, filtration speed and filtration area of ball mill dust remover
Q=kG
In the type: Q- handling air volume, m3/h;
G- mill platform output, t/h;
K- empirical coefficient, mill ventilation: 500 ~ 600m3/t; fine powder collection: 1200~1300 m3/t.
Example: the output of the cement mill is 20 t/h, and the dust collector is only the ventilation and dust removal equipment of the mill. The air volume should be 12000.
M3/h; closed grinding system consisting of ball mill and O-Sepa separator; the output is 100.
The mathematical relationship between the three aspects of air volume, filtration speed and filtration area of the ball mill dust collector is as follows:
Q=60Su
The ball mill dust collector type: Q- processing air volume, m3/h;
S- filter area, m2;
U- filter wind speed, m/min.
For example, when the output of the Q3 * 11m closed raw material mill is 70t/h, the ventilation rate for ventilation and dust removal is 42000m3/h. If the ordinary Dacron bag collector is selected, the filtering wind speed should be less than 0.7m/min, then the filter area of the dust collector should not be less than 1000m2.
