Why do you need briquetting machine?

What’s the application of briquetting machine in industry?

1.  Control dust pollution

2.  Reduce volume for less storage space

3.  Add density for materials that go back to the metallurgy furnace secondly.

4.  Recovery the materials that are seen as waste

5.  Obtain products of uniform size and weight

6.  Improve the flowability of the powders, thus preventing problems of feeding, dosage or package.

Engaged in this area for many years, we are provider for briquetting solution.

Wearing parts of briquetting machine - the roller

Working under high pressure, abrasive environment, the roller of briquetting machine is the most wearing part. The service life is of great importance to the economic profit.

The material of roller is an important factor. What we use is two kinds of alloy steel, 65Mn and 9Cr2Mo (for special purpose, stainless steel is also available). Generally, roller of 65Mn could serve about 6-10 months, while roller of 9Cr2Mo could serve about 12-15 months. Of course, service life also depends on the working hours and the materials you feed into the machine.

Even of the same alloy steel, rollers processed by different thermal treatment show different performance. Our roller would undergo several processes in sequence, annealing to reinforce the tenacity for further machining, quenching to improve the hardness after machining, aging treatment of 6-12 months to eliminate the internal stress. For some extremely abrasive materials, carburization of the roller surface is necessary. The thickness of 2-3mm would extend the service life a lot.

What can you conclude now? Obviously, we are an engaged, serious manufacturer of briquetting machine, briquetting press, roller press. If you need briquetting production line or briquetting plant, come to us for the professional solution.

How to choose suitable binder?

How to choose suitable binder?

Briquetting machine is applicable for various powders in waste & by-product, mineral & ore, chemical industry, such as mill scale, steelwork sludge, iron concentrate, sponge iron, magnetite, chrome ore fines, ferrosilicon powder, coal powder, caustic soda, quicklime or burnt lime, etc.

For most occasions, binder is used. Also, there are many different types of binder, which could be categorized into four groups based on mechanism:

1.   Van-der-waals force

2.   Mechanical linkage

3.   Forging

4.   Plasticization under pressure

Facing so many binders, which one is suitable for your material? Engaged in briquetting, HJ Machinery could give you the best professional advice. Both the type of binder and percentage are important.

Wrong type of binder wouldn’t give you satisfied result. And inappropriate percentage has bad influence on the strength.

Too less binder results in briquetting failure, too much binder brings more impurity which reduces the strength.

Binder or not?

Binder works as additives to hold the particles together during briquetting process. With binder coated evenly on the surface, powder could adhere to each other. Many different units come as one strong briquette. So, binder helps a lot for the briquetting machine to achieve the best performance. For wet powder briquetting, the moisture content is controlled around 12-15%. Sometimes, drying process is recommended to reduce moisture. After then, briquette strength comes to its highest level.

However, for some materials, binder is not allowed. Why? Some process has strict control on the impurity. It is binder, meanwhile, also impurity. What should we do for such occasion? Dry powder briquetting machine could solve this problem. Featured with high pressure, hydraulic system of dry powder briquetting machine compresses powder heavily. Van Der Waals force between molecules keep them together, rather than binder adhesion.

These two processes are of different mechanism.

Screw feeder of briquetting machine helps a lot for some materials that need high pressure

Screw feeder of briquette machine helps a lot for some materials that need high pressure

Screw feeder equipped on the briquette machine is not necessary for every material.

For some bulk materials such as quick lime, no additive is allowed. It is difficult to make quick lime into briquettes. So, additional pressure is required. This is where screw feeder shows its function.

While counter-rotating rollers are horizontal, screw feeder is vertical. With auger pushes material into the gap between rollers, screw feeder presses burnt lime heavily.

Thus, solid briquettes are formed.
