Case studies SPM Instrument
At Romanian paper mill Vrancart, the online system Intellinova Compact with HD condition monitoring technology is installed to monitor the press section of paper machine K25. This case study involves the detection of bearing damage on one of the press rolls, showing the development of the damage over a period of about six weeks.

Vertical Roller Mills FL
As vertical roller mills are 30 to 50 percent more efficient than other grinding solutions, they give cement plant owners a great opportunity to maximise productivity and minimise operating costs. The high energy efficiency is especially beneficial in regions with limited power generating capacity or where electricity availability is limited.

The grinding process of vertical roller mills
The grinding process by roller mills requires high grinding forces between the grinding elements. The forces have to be generated and transmitted to the parts where the size reduction takes place.

Case Studies Involving Continuous Process Analysis
Case Study: Innovative Equipment Design. In a comprehensive assessment of a range of mill types for producing a new marble powder, Ferrari Granulati engineers selected a vertical roller mill as the choice option. This selection was made based on energy efficiency and equipment footprint, but it also presented a challenge.

[PDF] Grinding process within vertical roller mills ...
Based on screening analysis, laser size analysis, grindability and rigidity tests of samples collected on line from a cement and a power plant, a simulation of the grinding process in vertical roller mills was carried out. The simulation calculation used a breakage function, B. The results indicate that the breakage function, B, and the selection function, S, in the form of a matrix, can be ...

Case Study RAW MILL GRINDING ROLLER 13
Aug 17, 2016· Two ball mills are designed with annual capacity of 4 MT each and vertical roller mill of 3 MT per year. 3. Case Analysis – In May 2016, abnormal size bearing wear particles of size ranging up to 100 microns were observed in marginal quantities in grinding roller oil sample. But the ferrous concentration was 73 ppm.

PROCESS CONTROL FOR CEMENT GRINDING IN VERTICAL .
The power ingesting of a grinding process is 5060% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 3040% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time
