Dust extraction at conveyor transfer point

Dust extraction at conveyor transfer point

Dust extraction at conveyor transfer point

(OP)
I am a junior Chemical engineer who has been tasked to find a scheme of reclaiming coal fines which have been and are currently been generated in our plant. The sieve analysis of the coal fines is given below.

Screen Analysis        %

+2000µm            18.2
+1000µm            11.5
+850µm            2
+500µm            12
-500µm            56.3

Moisture            1.50%


I have tried pelletisation using burnt lime as a binder but the pellets produced where not strong enough for as they crumbled during conveyance to the smelter.

The agglomerates formed are supposed to be reusable and must be tough enough to withstand both abrasive and compressive forces of up to 1 bar, and must have a mean diameter of 20mm.

I would be grateful for your inputs

RE: Dust extraction at conveyor transfer point

Kudzi,

There are dust collectors designed to mount directly over various belt conveyor transfer points. They are sized by determining the width and speed of the belt, distance of verticle fall and material being transported.
