INTRODUCTION. Traditionally, the closed circuit ball mill with high efficiency separator has been the most common system for cement grinding. However, as happened with raw grinding over the last 25 years, the vertical roller mill (VRM) is now successfully being used for many clinker grinding applications and is rapidly.
Ball mills, that are commonly used for finish grinding, have high energy demands, consuming up to 30-42 kWh/t clinker depending on the fineness of the cement. Complete replacement of ball mills by vertical roller mills (VRMs) with an integral separator – as opposed to the use of VRMs as pre-grinding to ball mills – is.
Cement clinker will be ground with the brand-new highlight, the LOESCHE mill type LM 70.4+4 CS. This mill is designed for a capacity of more than 370 t/h to a fineness of 4700 Blaine. In combination with this enormous capacity a new drive system for an operation power up to 8,800 kW is necessary. In a close cooperation.
Vertical Roller Mills are widely accepted as the most efficient means for grinding clinker, cement raw material (line, slag, gypsum) and coal in Cement industry & thermal power plants being an energy efficient process. Vertical Rolling Mills (VRM) Gearboxes from Vulcan provide.
The Vertical Roller Mill (VRM) has proven a universal tool for grinding line, clinker and slag in the cement industry. The maximum mill powers doubled.

The grinding of raw material and especially the challenging slag grinding is since many years almost completely in the hands of VRM.
A cement mill is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills. Contents. [hide]. 1 History; 2 Materials ground.

VRM are summarised in Table 1. The cement plant contacted Mapei for technical support, with the specific aim of increasing the strengths of the VRM cement in order to match the results obtained by the ball mill. If the clinker quality is the same, the cause of the differences in strengths can lie in the modification of particle.
