Redundancy and interchangeability large vertical roller
rollers made it possible to use the existing roller modules from mills that have already been operating successfully for many years. The roller module ( Fig. 3) of a Loesche mill consists of the grinding roller, the spring system, which transmits its hydrau-lically applied grinding forces via a lever system (rocker arm) to the grinding rollerA cement Vertical Roller Mill modeling based on the number of breakages. Vertical roller mills (VRM) are widely used to grind, dry, and select powders from various materials in the cement, electric power, metallurgical, chemical, and nonmetallic ore industries. For the sectors above, the VRM is a powerful and energy-intensive grinding Operational parameters affecting the vertical roller mill

Operational Failure of Vertical Roller Attached to a Grinding Mill
In the present incident, one of the rollers of grinding mill in cement plant failed during operation, exhibiting longitudinal cracking over inner surface. Deposition welding was carried out just before the incident to match the worn-out profile of the roller. Investigation revealed that the subsurface of the cracked region contained discontinuities Variations in feed rate increase vibrations of the mill, destabilizing operation and in the extreme resulting in mill stoppages. Observed feed variation in Fly ash. The mill feed material needs to be free of metal pieces. Higher the metal pieces frequent operation of diverting gate and results in feed variation.

Three Roll Mill Franli Machine
Three roller mill, with easy operating and safe cleaning. FRANLI nowadays has a different model of manual Triple Roller Mill, Hydraulic type, and Lab type. When grinding the material, it is generally ground several times according to the fineness requirements of the final product, and the set pressure of the three roller mills is usuallyMany flour mills introduced eight-roller mill in order to reduce capital cost. With this milling concept there is less installation, energy and maintenance cost, with fewer sifters, pneumatic lifts, filters, number of roll stands, spouting and auxiliary components and less space requirements (Baltensperger 1993,1997,2001 ; Posner and HibbsUsing the eight-roller mill in the purifier-less mill flow PMC
