Roller briquette press machine or roller briquette press is used to briquette the wet materials into the briquette.

Almost all the materials can be used in the roller briquette press machine, the following are some common materials:

Fuel: coal, charcoal, etc
Metal: oxide scale, mill scale, iron, aluminum, ferro silicon, copper, chrome, chromite, manganese, nickel, zinc, etc
Mineral: kaolin, laterite, magnesite, fluorite, fluorspar, silicon, dolomite, etc
Other: lime, plaster, coke, carbon black, gypsum, clay, sludge, converter dust, pigment, etc
For biomass briquette , we recommend to use other briquette machines, like the log briquette maker, screw bio briquettes machine, wood chip compactor and biomass brick briquetter.

Requirement of raw material
1.Size
High quality briquette comes from the small raw material, for common materials, less than 5mm is a good choice for energy saving and usage.
2.Moisture
Moisture is very important in briquetting process, if the material is too wet, it will stick in the roller hole and the machine won’t make briquette anymore, too dry, you can’t even get the shaped briquette.
So, what is the proper moisture for briquetting?
This is different from material to material, and also have something to do with the binder you plan to use.

A binder mixed briquetting process
In the roller briquette press process, the materials need to add binder before briquetting, we have different consideration for the binders, for example, if your material is too wet to briquette, we usually need to dry it, but if the moisture is not that high, we solve the problem by adding some dry binder not only for briquetting also for moisture controlling. The proportion of binder is different for different materials.

Herewith an article for you to learn more about binder: All about binders – make briquette with the proper binder

The briquette ball size
Size can be between 10mm to 110mm.

With further consideration of capacity and the briquette strength, our recommend size is between 25mm to 50mm.

A general single process for roller briquette press machine plant
wet roller briquette plant whole process show

Crusher ⇒ Silo ⇒ Mixer ⇒ Silo ⇒ Briquette Machine ⇒ Dryer

Crusher: If your material is too big, generally, a crusher must be needed, or else that will reduce the working life of the roller. Furthermore get proper size material is also a way to make well binder mixed material;

Silo: Silo is used to store the material for a smooth feeding for the next step;

Mixer: A good binder mixed material will get a high strength briquette as well as the briquette shaping rate. The water (if needed) and binder will be added here;

Dryer: You can choose vertical dryer or belt dryer according to your budget, if you have time and place to dry the briquette, you can even remove this equipment.
