Basic Introduction
Short vertical mill vertical roller mill , a cement raw materials, cement clinker, slag and cinder grinding process used, has a simple structure, low cost of manufacture and use characteristics. Between the body including, disc drive means and the means for centering the body and the structure of the disc device is provided to determine the rotation center of the bottom disc is fixedly provided with rotary guide means, the guide rail by the rotation of the disc means rotatably supported on the main body apparatus and the disc gear drive connection. Since the transmission does not bear axial load weight and high pressure grinding disc, so the transmission gear may be generic, which has the advantages of compact structure configuration, reliable, and can shorten the stop grinding time, reduce the use of equipment and maintenance costs.
Design Principles
The main study of the impact of the disc, the curvature of the roller grinding capacity, unit power consumption, in order to determine the optimal grinding curvature. Large parts of the disc and the seat frame and other major bearing pressure were static analysis and calculation of structures under dynamic loads, optimize the framework of cross-sectional dimensions determine the pressure to find the disc holder stress equally conducive to optimum shape of the casting process, and take full account of the effects of heat stress. Basic research and analysis, the development and design for MLS3626 efficient modularvertical roller Mill classifier. Control key consideration regional component separator and particle motion, limiting the mill appear as irregular exercise, from the surface to reduce the cycle load, improve grinding efficiency.
Vertical mill is the use of large-scale roll system to achieve high-volume grinding of materials handling equipment, its mill compared with ordinary strengths lies and operation of large-scale automation equipment. The current domestic market, vertical milling machine in a variety of powder
Process
Vertical mill conditioning tower and filter based on location, there are two different layout scheme, namely three fan system and dual fan systems. Product collected using a cyclone dust collector. This arrangement reduces the negative pressure system and work by the amount of gas precipitator. Electric dust collector can also be used as a final bag filter dust removal equipment; dust collection device can be used in electrostatic precipitator or a bag filter, the mill gas directly into the dust collector, the system reduces the number of equipment units simplify the system configuration.
Frequently Asked Questions
Vertical roller mill roller body wear
Vertical roller mill body and liner wear during use, due to the friction roller grinding pressure, the material support reaction force, the material between the liner and the roller; grind into a corner because of the material caused by roller shear the combined effects of stress each other, roller mill hydraulic system pressure and the apparent stress, such as vertical mill forces, these forces are acting on the vertical mill grinding roller compacted area effectively. Once with a gap, will impact collision between the body and the liner, making between the body and liner wear and tear, making the lining severe cracks or fracture, causing the liner off, machine damage, especially reducer damaged, resulting in a vicious incident. Once such problems occur, the general repair methods are difficult to solve, demolition, welding, machine processing fees when consuming, downtime downtime caused by greatly extended, to bring irreparable huge economic losses. In response to these problems, Europe and other developed countries make more use of polymer composites repair site, where more mature application Blessed World Blue series. Material for its excellent mechanical properties and good plasticity, making a satisfactory solution to the problem. Not only prolong equipment life, improve productivity, and do not take up extra downtime downtime, while simple and effective to avoid the possibility of the issues that arise secondary to continuous production enterprise security escort.
