Product Introduction:
In practice, some materials are difficult to shape, and the binder is unwanted. So in this case, a briquetting machine with higher line pressure is needed. Generally, we consider a roller press with a line pressure ratio of more than 20 t/cm to be an ultra-high pressure ball press.
Main Features:
Compared with the high-pressure briquetting machine, this equipment has unique characteristics.
- All motors and reducers have a direct structure, which makes the transmission more accurate.
- The application of a variable pitch screw is indispensable, and it also brings a better result through the accurately machined prepress screw.
- The sealing technology on both sides of the prepress screw and roller is one of the important features of the briquetting machine. Its sealing effect better ensures no pressure relief for material that is under ultra-high pressure and in a closed environment.
- The automatic control and protection ability are strengthened in the control system.
Briquetting Principle:
The powder material is compressed between a pair of rotating rollers, the one is movable and it provides pressure through a hydraulic system. It might be a single material or mixed material, even a binder is needed sometimes.

Process:
Different materials have related briquetting performance, which requires a reasonable and optimized machine. It is also significant in taking the quality of the final product into consideration.
The briquetting performance of a material depends on itself, such as the fineness, grain size, water content, composition, etc., which usually needs to be determined by testing.
Not all materials have sphericity, if the bonding force between the material particles is low, a suitable adhesive is necessary. According to the physical properties of the material and the purpose of the final briquette, the choice of binder needs to be made based on its bonding performance and use cost. Various adhesives such as starch, bentonite， asphalt, quicklime, cement, water, flour, lignosulfonate, molasses, polymers, resins, sodium silicate, and new composite binders are for specific purposes.
The key process of briquetting machine is 'continuous quantification', which usually requires continuous batching, mixing, and subsequent drying links.
In practice, Kaizheng has accumulated considerable experience with a complete turnkey system, including electrical interlock and interface control, that integrates system molding units to meet your specific needs.
Note: The process varies relating to different materials and applications.
