Roller mill tests can help determine the right roll speed ratio for your material. Roll gap. Controlling the roll gap (Figure 3) is critical to achieving your required final particle size. This control has two components: the roll gap size and roll alignment. The roller mill operator can control the particle size by widening or narrowing the ...
A twocompartment ball mill with a highly efficient separator is still procured for new cement grinding units installation, although the vertical roller mill has now become a true. Vertical roller mill. The feed is ground by pressure and friction between the horizontal rotating table and 4 to 6 grinding rollers in the VRM.
A Loesche vertical roller mill can be used for slag comminution, and Andreas also gave details of a dry densityseparation step based on a fluidised bed approach. Such a process has been installed at the Orbix (Recoval/Recmix) stainless steel slag processing plant at Farciennes in Belgium, driven in large part by the economics of metal recovery.

Cast Steel Node Slag Pot for Furnace Tyre of Rotary Kiln.
Comminution theory focusses on the relationship between energy input and the particle size produced from a given feed size. 2 The most common breakage methods are impact and attrition, mostly by ball mills. This compares with the compression mechanism, as well as attrition, utilised in both highpressure grinding rolls (HPGRs) and vertical roller mills (VRMs).

(granulated blast furnace slag, fly ash, pozzolanes, limestone etc.). The grinding of the finished cement consumes approximately one third of the total electrical energy of a cement plant. Vertical Roller Mills (VRM) have a clearly higher energy efficiency than ball mills, even if the ball mill is combined with a roller press.
Steel slag powder products have good market prospects. At present, the existence of free CaO and MgO in steel slag reduces its volume stability; The high content of iron oxide increases the grinding difficulty, high power consumption per ton of slag powder, and difficult processing of steel slag powder. Therefore, the sales volume of steel slag powder is small.
Compared with other equipment, the slag vertical roller mill has obvious advantages in energy consumption, which can save more than 40% of power consumption, and has low noise, low maintenance cost, good shape and stable quality of finished mineral powder. Therefore, it has become an ideal slag grinding mill equipment choice for slag powder.
