Figure 5 shows the cloud diagram of the vertical roller mill with different crosssectional speeds (m/s) and local velocity vector. It can be seen that the wind speed at the wind ring is the largest in the entire basin with a maximum airflow speed of m/s, and the wind speed of the wind ring has a direct impact on the classification efficiency.
has developed this cement grinding system which is a fully airswept ring roller mill with internal conveying and grit separation. This mill is a major improvement of the cement grinding systems known today which are ball mill, roller press (HPGR)/ball mill, vertical roller mill and closedcircuit roller press for finish grinding.

The application of vertical roller mills (VRMs) for ore grinding is a part of the strategies against rising energy consumption (Reichert et al., 2015). 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.

Within the scope of the study ore grinding performance of the vertical roller mill was investigated with mobile pilot plant. In this context, chalcopyrite ore of a plant having rod and ball milling circuit was ground under different operating modes, air swept and overflow, and process conditions, then samples were collected around the system.
Ball mills for cement raw material and coal equipped with a drying compartment adequately air swept with hot gas (/sec above the ball charge), can handle moisture about 8%. Fully air swept mills (56M/sec) can dry up to 1214% moisture. Grinding Operation Objectives and KPIs: Highly energy intensive unit operation of size reduction in ...
