A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

Vertical roller mills (VRMs) are wellestablished grinding equipment for various tasks in the coal and cement industry. There are few studies on simulation of VRMs. In this research work ...
Overall, the maintenance costs are not dissimilar for both types of mills: while the wear rates for a ball mill are higher than for a VRM, the cost of the replacement parts is lower, and the opposite applies for the VRM lower wear rate but higher replacement costs. Product quality
The VRM technology was introduced in the mid'90s for grinding clinker and slag by LOESCHE (Schaefer, 2001). Fig. 1 illustrates the grinding parts of a Loesche vertical roller mill. The grinding material is comminuted in the Loesche roller grinding mill between the rotating horizontal grinding track and stationary grinding rollers.
As the Vertical Roller Mill (VRM) becomes more widely accepted for new cement grinding systems differences in installed costs between a VRM and a ball mill system are more frequently discussed. Past comparisons of total installation costs for a ball mill with high efficiency separator versus a VRM have indicated the higher equipment costs associated with the roller mill made it a more ...

A more appropriate term is vertical roller mill or VRM for short. There are two different types of vertical mills: Vertical roller mills. Such mills normally have integrated classifier. This means plant design is more compact / simple in comparison to ball mill / classifier circuit. On the other hand fineness is limited. Agitated vertical mills.
The vertical roller mill itself is equipped with a powder concentrator, which can remove fine powder in time, reduce the phenomenon of overgrinding and improve the grinding efficiency. The vertical roller mill is less power consuming. The energy consumption of a vertical roller mill is around 75% of that of a ball mill of the same capacity.

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 ...

Optimum performance of ball mill could potentially refine Blaine fineness, thereby improving the cement quality. This study investigates the effects of separator speed and mill speed on Blaine ...
Due to the compact design and material transportation system of vertical roller mills (VRM), some important streams (total mill feed and discharge, dynamic separator feed and reject) remain in the ...
A specially designed laboratoryscale VRM was constructed in the powder research center in Hefei, China. Fig. 1 represents the schematic diagram of VRM utilized in the experiment and DEM simulations. The diameter of the millstone and grinding roller are 600 mm and 340 mm respectively, and the angle between the centerline of the grinding roller and the horizontal is 13°.
Differences between Cement Ball Mill and Vertical Cement Mill Grinding Mechanism. The grinding mechanism of a ball mill is a series of impact and attrition events that occur inside a large rotating drum. The grinding media collide with each other and the material being ground in the drum, creating a large amount of heat.
and vertical roller mill, VRM [35]. Among these devices, VRM plays an important role in cement, accounting for more than 55% of China's cement raw meal market [6], and its performance directly affects the cost of producing cement. VRM has the functions of grinding and powder selection, including a grinding unit and an air classifier ...

than ball mills, even if the ball mill is combined with a roller press. This and further arguments led to the increased share of VRM for the grinding of finished cement. Taking into account that VRM usually have a bigger output than ball mills, it can be declared that the major part of the cement production with newly installed mills comes from ...

Vertical Roller Mill (VRM), a cutting edge technology, can be installed to grind the hard, nodular clinker from the cement kiln instead of inefficient ball mills that can save up to 15% energy [63]. Inclusion of flexible speed drive used for cooling purpose can further reduce electricity consumption.
