Coal Extruder Machine Make Briquette with Hole or not

Addtime:2014-8-12 16:18:53   Author:manufacturer   visited:1079

As we know, the coal extruder machine can make briquette of different shape.

And some briquette has a hole in center, while others not.

How does it happen?


Now we will tell you the reason:

There is one propeller inside the coal extruder machine to push and press

the coal powder into briquette. If there is one long stick at the front end

of propeller, the briquette will have a hole. If not, then the briquette will

have no hole in center.

If you have any question about coal extruder machine, please contact us freely.


Material for biomass briquetting

The best materials for briquetting are sawdust and other woody residues, because these contain a high proportion of lignin. However, most dry agricultural residues can be used if they are ground into a coarse powder. Grain straw and dried grasses do not make good briquettes on their own, but work well when mixed with woody materials to provide the lignin. Bagasse, shells (such as from peanuts) husks (such as rice husks and corn cobs) and pine needles make reasonable briquettes. However rice husks are abrasive due to their silica content, and can reduce the life of machine components.
