1. Introduction Mineral crushing is the main source of energy consumption in mineral processing. According to statistics, this consumption accounts for about 3550% of the total cost of the mine (Curry et al., 2014 ), or even higher. It may also account for % of the global electrical energy consumption ( NapierMunn, 2015).

In the past, high pressure grinding rolls (HPGR), vertical roller mills (VRM) had positive effects on the overall energy utilization of cement grinding however some quality issues had also been ...
a vertical roller mill (VRM) • Surpasses the classic methods if the controlled process demonstrates significant disturbances • A high degree of attention to the process states is required in order to make punctual corrections • Process states are displayed and controlled continuously for realtime optimisation
As a result of the higher ∆Pmill, the mill vibration increases. (8 10mm/s), which results in a good opportunity to test the effect of the grinding aid. In contrast to tests with ball mills, the effect of grinding aids in a VRM is already visible and audible after 10 20min. Table 1: Data used to produce Figure 3.
This work concentrates on the energy consumption and grinding energy efficiency of a laboratory vertical roller mill (VRM) under various operating parameters. For design of experiments (DOE), the response surface method (RSM) was employed with the VRM experiments to systematically investigate the influence of operating parameters on the energy consumption and grinding energy efficiency.
The Vertical Roller Mill (VRM) is a large piece of equipment for grinding materials and is usually used in the production fields of milling slag, cement raw material, clinker, and coal. With the development of social productivity, the grinding industry is making increasing demands on the production capacity and efficiency of equipment, and the

1. INTRODUCTION The VRM is a type of grinding mill integrated with multi functions such as grinding, drying and separation, used for grinding of coal, petroleum coke and minerals. Most recently this technology has been employed for comminution of Blended, Slag and Port Land cement grinding.
The LM 3,6 is an air swept mill which combines grinding and classifying in one single machine, with the classifier installed above the grinding table. A Simplified flowsheet of the pilot plant configuration is given in Fig. 1. Material is fed into the vertical roller mill chamber and ground between the rollers and the rotating table.
Vertical Roller Mill repairs Excellent references During the last decades, together with our partners, we have proved that preventive maintenance on VRM can extend the critical component lifetime by as much as 100%. Such maintenance operations have been performed on over 2000 units in more than 24 countries, with 80% being onsite repairs

1. Ball Mill (BM): historically the mill of choice, it still predominates today and accounts for > 85% of all cement mills installed globally; 2. Vertical Roller Mill (VRM): commonly used for grinding of granulated slag but increasingly also for cement grinding and accounts for approximately 15% of the global cement mills; 3.
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.
