Raw material vertical mill

High grinding efficiency. By adopting advanced material layer grinding principles, the system's power consumption can be reduced by 20-30% compared to ball mills. As the moisture content of the raw materials increases, the energy-saving effect becomes more significant;
● High drying capacity. Materials can be dried using kiln hot air exhaust gas, and raw materials with a moisture content of up to 15% can be simultaneously dried and ground;
The equipment has a small footprint and a simple process flow. The HRM vertical mill integrates fine crushing, drying, grinding, powder selection, and conveying without the need for additional drying, powder selection, and lifting equipment. The workshop area only accounts for 70% of the ball milling system, and the space only occupies 50-60% of it;
Low noise, minimal dust, and clean operating environment. The grinding roller and grinding disc do not come into direct contact during operation, there is no metal impact, and the noise is 20-25 decibels lower than that of a ball mill. The system adopts fully sealed negative pressure operation, with no dust and a clean production environment;
Low wear, minimal metal contamination of the product, and metal wear is generally only 5-10g/t.
The grinding roller sleeve can be flipped over for use, which is beneficial for extending its service life and reducing production costs. Easy operation and maintenance;
Grinding products have stable chemical composition and uniform particle size distribution, which is conducive to calcination.
