Why charcoal briquette

Charcoal briquette is widely used around the world for BBQ, fuel, etc. It’s really a big deal that a lot of companies doing the charcoal making around the world when making the charcoal, there will be a lot of fine charcoal dust we need to collect and find ways to deal with them. Studies show that in charcoal manufacturing establishments, fine waste constitutes 10 to 15 percent of usable charcoal. So there comes a big inquiry for charcoal briquette machine to do the briquette work. And also for other low-density wood and bulky materials like coconut husks, corn cobs, etc, in order to improve the quality of the charcoal for further usage, we make these charcoal into briquette as well.

Charcoal sources

charcoal from low-density wood and bulky materials like bamboo, coconut shell, corn cobs, etc;

charcoal from wood waste during logging, lumbering and veneering such as wood log ends, stumps, wood branches, twigs, barks and trimmings;

charcoal from the fine argo-forestry waste materials such as sawdust, rice husk (rice hull), coconut coir dust, etc;

charcoal from tree plantations.

If you want to make biomass charcoal by the way of biomass⇒biomass briquette⇒biomass briquette charcoal, please to learn.

In order to make your raw biomass material into charcoal, you will need a  furnace or something to do this work.

Prepare your raw charcoal

Before we make the charcoal briquette, let’s learn the requirement for charcoal fines and other things for charcoal briquette machine.

Size

Small material size is always good for charcoal briquette making before you make your charcoal briquette, please check all of your charcoal fine with the proper size. We recommend you the of under 5mm for making good quality charcoal briquette.

moisture

A moisture around 30-40% is working with the charcoal briquette process, high moisture will build a briquette with high density and with low energy cost on briquetting process.

Briquette charcoal with binder

Charcoal is a material totally lacking plasticity and hence needs addition of a sticking or agglomerating material to enable a briquette to be formed. Thus Binder becomes a very important factor is charcoal briquette making process, pure charcoal is a thing which burns with no smoke, no smell.  The use of charcoal determines the type of binder it uses, for industry usage, there would be wider choices in binders.

Some binders: starch, clay, slime, tar and pitch, molasses, resin, animal manure, sulphite liquor residues, etc.

Other additives
It is possible to add material to aid combustion of briquettes such as waxes, sodium nitrate, and so on, during manufacture to give a more acceptable product. Also, clay as a binder, silica, and so on, can be mixed with the fines to reduce the cost of the briquette. This, of course, lowers the calorific value and is merely a form of adulteration for which the user pays, though claims may be made that burning is improved. But well made briquettes are an acceptable, convenient product. The virtual absence of fines and dust and their uniformity are attractive for barbecue purposes. Generally, they sell at around the same cost per kg as lump charcoal in high price markets and have more or less the same calorific value as commercial charcoal of 10-15% moisture content.
Usage of some common additives: brown coal (heat source), mineral carbon (heat source), borax, sodium nitrate (ignition aid), limestone (ash-whitening agent), raw sawdust (ignition aid).

Benefit

Charcoal briquette is a very good fuel compare to biomass briquette which is also widely used. When we turn the biomass into charcoal, after a series of pyrolysis reactions, we remove the smoke, smell and only leave the carbon with the raw material, this makes the charcoal briquette with the advantage of smokeless, odorless and high burning value (80% ahead of biomass briquette) when burnt.
