We produce the new technology ultra fine vertical roller mill rely on 12 years of experience in the production of ultra fine powder mills and based on German and Taiwan technologies. The top technical team members were joined this project. Besides, high-quality wear-resistant parts are used to develop milling equipment which in a real sense marks the first secondary classifying technology in mainland China, having product fineness of 400-6000 mesh. And if you use the wet grinding method to process the superfine stone powder, the final powder fineness made by our vertical roller mill can up to 10000 mesh.
As for the operation and maintenance of the ultra fine vertical roller mill, we must ensure operate person take good care of the control cabinet, regularly check the cabinet outside the cabinet, to maintain the instrument is clear and bright, flexible operation handle, the main electrical shock. Regularly check the components and connections are loose, damaged. Every half a year to measure the insulation resistance, find the problem in time.
The technology data of the 10000 mesh ultra fine vertical roller mill as follow:
