ATOX® Coal Mill

Our ATOX® Coal Mill is a compact vertical roller mill that can grind almost any type of raw coal. The coal mill utilises compression and shear force generated between the large rollers and the rotating table to crush and grind raw coal, removing the need for a separate piece of equipment for crushing. The coal mill can also grind petroleum ...

The Experimental Determination of Coal Mill Models

This paper describes the experimental measurement of coal-mill transfer functions at a 380 Mw steam turbine generator of TransAlta Utilities in Canada. Measurement equipment was used that estimated the parameters of the transfer functions from digitized transients obtained during on-site tests. These preliminary tests were part of a sequence of tests …

Section Views in Drawings

You can create a rotated section view by overlaying sketches on a view. Removed Section Views. Removed section views show slices of the model at selected locations along a drawing view. Part Cutaway Views. The part cutaway view creates a section in a pictorial (isometric, trimetric, or dimetric) view. This method relies on part configurations.

ATOX coal mill

ATOX coal mill. Working principles The raw coal enters the mill via a rotary sluice and feed chute and is discharged onto the rotating grinding table. The rotation of the table accelerates the flow of material towards the grinding track, where the coal is ground between the table and the three rollers. The coal then continues over the dam
