A roller briquette machine is generally used to layout briquette with small size and high strength, this continuous briquette machine makes a highly smooth process and with much lower maintain cost.

The name of the machine comes from its structure, it contains two roller which are together rotating with opposite direction with tiny gap between them, the tiny gap makes a high pressure when on briquetting. Thus the briquette is made.

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

Materials:

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, 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

Requirement for 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.
   Here is an example:
   In coal briquette making process, when using lime and clay as binder, the moisture should be between 18-20%, but when use pulp or sodium humate as binder, the moisture requirement change into 10-12%, if the binder is asphalt, the moisture even low to 2-4%!

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

Another important thing for binder

Usually we choose binder which cost less and is easy to get, herewith some common binders which may be very suitable for you to get and use.
starch, syrup, cement, etc.

What about the briquette size

The size can be between 10mm to 110mm, but with further consideration for capacity and the briquette strength, we recommend to use the size between 25mm to 50mm.

The shapes of briquette

shape from left to right (round, pillow, square, lath)

Above are some common shapes for this kind of briquette machine, we also manufacture some other special shape according to what you need.

Roller

We usually use two kinds of material for rollers, 65Mn and 9Cr2Mo. The 65Mn roller is a kind of steel castings material with low cost and the 9Cr2Mo roller is high chromium alloy material which cost more but with higher wear resistance.

All of the two rollers are treated with our special heat treatment to make it with high wear resistance. For different briquette materials, you should choose roller by your condition. Generally, the 65Mn roller is used in small briquette machine with soft material, such as coal, charcoal, carbon, etc. And the 9Cr2Mo roller is usually used in the big briquette machine with materials such as mineral, iron powder, laterite, etc.

Application:

• Metallurgical industry. The fine of non-ferrous metals and ferrous metals can be briquette and re-smelting, such as laterite nickel ore, alum ore, manganese ore, furnace dust, steel slag, mineral waste residue, carbon black, copper powder, magnesium, alumina, iron ore concentrate, manganese ore, etc.
• Coal fuel briquette making. Making coal briquettes from coal fines, coke powder, slime, and midding coal, etc, the briquettes are used in industrial boilers and civil furnaces.
• Thermal power plant.  Use the desulfurization gypsum making briquette as cement retarder.
• Chemical fertilizer industry. using coal dust to make briquette, instead of using lump coal, saving energy cost.
• Building materials industry. The ceramic factory, glass factory and the coal- gas generator, using coal fine briquette replace the lump coal for energy cost saving.
• Refractory industry. Making refractory briquette.
• Every kind of industry with powder material which should be briquette and then used in the kiln.

Roller briquette press machine plant

A general single process for roller briquette press machine plant

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. Further more, 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 next step;

Mixer: A well 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.
