Vertical Mill

The vertical mill is an efficient grinding equipment integrating crushing, drying, grinding, and classification, widely used in cement, metallurgy, mining, etc. It operates by grinding materials between a rotating grinding disc (ZG35CrMo) and 2–4 grinding rollers (high-chromium cast iron), with hot air drying and carrying powder to a classifier for separation.​ Key components include the main shaft (42CrMo forging), hydraulic system (10–30 MPa), drive system (160–1000 kW motor), and powder collection system (cyclone + bag filter). Manufacturing involves precision casting/forging, heat treatment, and CNC machining, with quality controlled via material testing, NDT, and performance trials (dynamic balancing, load tests).​ Installation requires a stable foundation, precise alignment of components, and system commissioning. It offers 30–50% higher efficiency than ball mills, with adjustable product fineness (80–400 mesh) and low energy consumption
