Series HKSF

Super Sonic Filter

The super sonic filter separates conveyed product from the air and cleans its bags with compressed-air pulses, keeping the line continuous and dust-free.

Series: HKSF

The super sonic filter is the jet-pulse bag filter that separates product from air at the end of a pneumatic conveying line. Product-laden air enters the housing, dust and flour are retained on the outside of the bags, and clean air leaves through the top to atmosphere or to the fan.

The bags are cleaned by compressed-air pulses through valves that fire in sequence. Because cleaning happens while the machine runs, the line is never stopped and the pressure drop stays constant.

Housing dimensions, bag lengths and weights are given in the model table. Bags are fitted and removed from the top without tools.

Key features

Automatic jet-pulse bag cleaning
Continuous operation without stopping the line
Constant pressure drop for stable conveying
Top-access bag changes without tools
A wide range of housings and bag lengths in the model table

Applications

The end of pneumatic conveying lines
Dust collection in mills and feed plants
Silo filling and discharge points

How it works

Working principle

Grinding turns cleaned, conditioned grain into flour, semolina and bran in several passes through roller mills and plansifters.

1A feed roll meters the stock into an even curtain across the full roll length.
2Two counter-rotating fluted rolls, one faster than the other, shear and crush the grain in the nip; pneumatic engagement lifts the rolls apart when the feed stops.
3The ground stock falls to the outlet and is conveyed to the plansifter, which separates it into fractions for the next pass.
