The vertical roller mill (VRM) is commonly used for secondary and tertiary crushing processes in numerous industries. In this study, the discrete element method (DEM) was employed to explore the crushing in an overflow VRM without air involved via the bonded-particle model (BPM). Particle crushing experiments on a laboratory-scale VRM were ...

The document compares roller press and vertical roller mill (VRM) circuits for grinding slag, finding that roller press circuits use 3-5 kWh/t less energy and have lower maintenance costs due to easier component access and longer lasting stud linings than VRM circuits requiring frequent tyre hardfacing. Roller press circuits also have lower civil construction costs than VRM circuits.

A multi-domain model is presented for the institute's in-house laboratory vertical roller mill (VRM), which has been validated with physical demonstrator data. The pilot-scale VRM LM 3.6/3w shown in Fig. 1 represents the central component of a realised new dry and wet grinding circuit. Hence, the mill is designed for operation in overflow modes.

The FL vertical roller mill (VRM) was chosen to produce a full range of cement types at the Muktarpur Plant. Driven by two 5.8 MW FL MAAG Max Drive gear systems, the impressive mill is the biggest VRM ever to be installed in a cement plant in terms of dimension, operating capacity and installed power.

With the market demand for efficient, highly flexible, and high-capacity plants for cement production, it was time to develop an innovative drive concept to cope with the demand: the world's first vertical roller mill (VRM) with driven rollers. With this concept, it is the rollers of the VRM that are driven, not-as is usually the case-the grinding table. With the roller-driven …

Roller press finish‑grinding systems, due to lower fan power demand compared to a VRM, exhibit a lower specific energy consumption. The only restriction of such a system is the maximum roller size of 2.2 m with an installed motor power of 3400 kW, which is 2380 kW absorbable power, limiting production of a 3600 Blaine OPC cement to around

In a VRM the grinding takes place by pressure and shear force. The clinker passes within seconds between roller and table. The energy input to the material during one passage between grinding rollers and grinding track is relatively low. The thick-ness of the material bed between roller and table is a multiple of the particle size.

The feed rate of the clinker VRM is 160t/h. The VRM has four rollers including two big rollers (master rollers) and two small rollers (slave roller), which respectively perform grinding and make material layering on the grinding table. Fig. 2 shows the simplified flow sheet of the VRM grinding circuit at Ilam cement plant. Fig. 2.
