Vertical Roller mills
Main parts of a vertical roller mill
Nozzle and retention ring
Vertical roller mill: frame type
Gbr. Pfeiffer: MPS
Vertical roller mill: rocker arm type
Processes inside a vertical roller mill
The material is trapped between the rollers and the table
When the hot gas trap the material leaving the table
From the table to the separator through the gas
The fine product from the coarse one and sending the last one back to the table
Grinding: material distribution on the table
Grinding: compression of the material
Pneumatic transport to the separator of the material leaving the table
Mechanical transport of the material falling down through the nozzle ring

Very good information thanks and we need instrumentation formula s and operation principal s send me sir
Very good information thank you I have to CCR kiln operation and formulas and ball Mills and vrm calculations please send me. Chemical formulas.
It is to be assumed that during grinding of raw materials, raw mill feed increased and decreased up to (2 to 5%) of total feed in both cases vertical and ball mill. Up to my understanding when every parameter is going well this change in feed is due to slight change in recepies , due to pile change (HGI), increse or decrease in dust %age in feed, some other miner factors which are not usually checked on hourly basis.
In case i am right then please tell me how much %age of feed increse or decrease will consider a normal variance.
