Now, the mixed raw materials move towards the grinding process which is carried out by vertical roller mill (VRM), one of the most ultra-modern technologies in the cement manufacturing. The raw materials then get converted into tiny particles which are filled inside silo. For further homonizing, the particles undergoes aeration process.
1)Use of industrial waste (slag, pozzolan) 1)Conversion of fuel from petroleum to coal 2)Conversion of SP to NSP 3)Conversion of planetary cooler to grate cooler 1)Conversion from wet process to dry process 2)Replacement of ball or tube mill by vertical roller mill 3)Pneumatic transfer of raw material to mechanical transfer Third step
Also, there is only one study by Austin et al. (1981) on the coal sample with respect to vertical mills. However, there has been no study on the use of the kinetic model for materials other than coal such as calcite, barite, talc, in a Hardgrove mill that best simulates vertical roller mills.

The reliable Hydraulic Roller Press outperforms ball mills and vertical mills when it comes to finish grinding. While the Hydraulic Roller Press can be used to upgrade ball mill systems for energy efficiency and enhanced production benefits, it is also exemplary in upgrading your vertical roller mill.
In addition, when the grinding roller mesh is bad, can be resolved through to the mill spray. Modern roller roller diameter up to 2 m, and up to 1.4 m, the extrusion pressure of about 50 ~ 350 MPa, grinding roll around the line speed of about 1 ~ 2.0m/s, the high level of energy utilization, has now reached 600m2/kJ (vertical mill is 450 m2/kJ ...
In 1662, another mechanical genius, G.A. Bockler, developed a mill using two corrugated rollers together with an agitating device for sifting the grind. Eventually the use of rollers for milling was widely adopted in western and central Europe. A concentration of roller mills in and around Budapest gave the name, "Hungarian," to the process.

CSI's Hot Strip Mill includes six finishing mills, which reduce the thickness of the transfer bar down to the gauge required by the customer or the next process. The rolling speed is set to allow the last stand to perform the final reduction at the finishing temperature, between 1500° to 1650°F, specified to reach certain mechanical properties.
The Williams Roller Mills are designed to provide years of reliable, consistent, and efficient operation, but the reason why Williams is one of the leading roller mill manufacturers is their ease of use and maintenance.

Vertical Roller Mills: In Vertical Roller mill 2 - 4 rollers (lined with replaceable liners) turning on their axles press on a rotating grinding table (lined with replaceable liners) mounted on the yoke of a gear box. Pressure is exerted hydraulically.
The roughing mill consists of six flat-vertical short stress mills arranged alternately. The nominal diameter of the roll is 550 mm, and the length of the roll body is 760 mm. The range of application is 610 mm to 520 mm. There is a crank flying shear at the exit of rough rolling mill. The maximum cross-section is 4000mm.
The principle of the new generation of vertical mill was to direct higher pressure from the grinding element to the material bed using hydraulic systems. From this approach the roller press, CKP (pre-grind vertical rollers) and Horomill ™ all developed. Raw milling. The gas-swept vertical mill quickly became the raw mill of choice.
