The ratio of water is one key factor to decide whether we can make good charcoal briquettes, no matter what kind of charcoal briquetting machine we operate, hydraulic punching pressure type briquette machine or extruding type briquette machine. Actually, to high quality charcoal briquettes required high technical skills of how to add water. Using much water will decrease the density of finished charcoal briquettes, if adding less water, the final briquette charcoals are easily damaged while being punched and extruded, even the press machine will be blocked by the charcoal mixtures.

Here one mistake always is made by users. For example, we use 100 kg charcoal powders, some people will add 50% water into charcoal powders directly, this is a low-level mistake. Regarding 50% moisture, which refers to the total water content, it is necessary to reduce the water contained in the carbon charcoal powder itself, that is the correct amount of water we need to use.

Here, we will talk about the normal amount of water added to the charcoal materials by several types of charcoal press equipment:

For mechanical type pressure machine, the ratio of water added is 28% - 35%, if less water, it is not easy to form the charcoal briquettes, even if it is barely briquetted, it will be easy to disperse. When the water is added more, there will be a kind of flexibility between the charcoal materials, which will result in loose density of charcoal briquettes.

Hydraulic shisha charcoal press machine

Regard to hydraulic pressure type charcoal press machine, the amount of water added is 15%-20%. This is because it is forced to pressurize and can hold pressure. Therefore, if the materials have less moisture, it can be compacted. If the water content is too high, the charcoal materials will be squeezed out from the side of the column due to the high pressure, the machine can not be fed enough to make good charcoal briquettes.

Charcoal Briquette Extruder Machine

For screw extruder, the amount of water added into charcoal materials is 30-40%. Because the screw pushing surface is large, so when the amount of water added is too small, it is easy to get stuck, which will also cause the mold to heat up, and the charcoal bars will crack easily. If adding more water, the extruded charcoal rod is too soft, which is hard to pick up, the most important is the density of charcoal rod is too low to burn for a long time.

Is it necessary to weigh the water amount before each briquetting? Or do we have to test how much water is contained in the charcoal powder itself? When you have no experience, you must do it according to the exact data. When you know what kind of humidity the material is stirred by the data, grab it by hand and feel the humidity. Once you has mastered the skills and gained more experience, you can easily know how much water you need to add.
