roller press

Main features: The transmission system: Motor--Elastic coupling (belt drive)--Twin-shaft reducer--Gear coupling--two rollers. Roller structure: Mosaic structure with laminated roll sleeve. Roller material: 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. Knowlege and experiance are need for the selection of roller material. Cooling system ,in particular, the selection of cooling area and the control of cooling cycle are the core technique. The cooling media can be soften water or heat transfer oil. Note: Specific crushing equipments are installed regarding to certain materials, for seperating the likely adhesive briquettes.

Briquette machine is the main equipement with the applied powder material forming technology. Its apllications 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 briquetting machine, once its line pressure is 50-120KN/cm. The common ones are 80KN/cm,110KN/cm,120KN/cm and 150KN/cm.

The high pressure granulating is a vital technological breakthough in the process of grinding with roller press. This technique is wide applied in cement and mineral processing industries. Grinding Roller Press Applied materials: Cement clinker,Raw cement materials (limestone, clay),Slag,Titanium oxide,Mineral,Synthetic fiber.

In practice, some materials are difficult to shape, and the binder is unwanted. So in this case, a briquette machine with higher line pressure is needed. Generally, we consider a roller press with a line pressure ratio of more than 20t/cm is an ultra-high pressure ball press. Compared with the high pressure briquetting machine, this equipment has its unique characteristics: 1. All motors and reducer have a direct structure, which makes the transmission more accurate. 2. The application of variable pitch screw is indispensable, and it aslo brings a better result through the accurately machined prepress screw. 3. 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 under the ultra high pressure and closed environment. 4. The automatic control and protection ability are strengthened in control system.
