Product Introduction:
Briquetting machine is the main equipment with the applied powder material forming technology. Its applications can be seen in a wide range of industries. Briquetting, as a stage of the process, it could be aimed for minimizing the need of dust removal and ventilate, it could be an end-product for selling.
We consider it as high pressure once its line pressure is 50-120 KN/cm. The common ones are 80 KN/cm, 110 KN/cm, 120 KN/cm and 150 KN/cm.
Main Features:
- The transmission system: motor--elastic coupling(belt drive)--double outletreducer--gear coupling--two rollers.
- Roller structures: hot-mounted structure, detachable expansion and tightening sleeve, and Mosaic structure with the segmented roller sleeve.
- Roller materials: High quality bearing steel, cold working die steel and martensite stainless steel (suitable for acid materials).
- Bearing assembly: return sleeve structure, equipped with special tools for disassembling and assembling.
- Prepressing screw: It is one of the core technologies. According to the material characteristic (mainly refering to the fluidity, the abrasiveness, the granularity), it is specially designed with cleaning and extrusion functions. Variable pitch spiral is designed for hard molding materials.
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 single material or mixed material, even binder is needed sometimes.
Process:
Different materials have related briquetting performance, which requires a reasonable and optimized machine.It is significant in taking the quality of 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.
