This solution can reduce emission level dust.
The gases are introduce in chamber, with temperature between 250 and 350° (limit temperature: 500°C).
A crossing by screw will be create a rotation movement of gases.
The dust into gases are centrifuged and collected in a receiving hopper, and then evacuated through an airlock into a barrel or big-bag.
A panel output collecting all gases in the case of a multicyclonic dust collector.

Advantage :

• Investment is limited
• Almost zero maintenance because no moving parts is used
• No consumables
• possibility to work at high temperature
