In recent years, Chinese infrastructure including high-speed rails, road and building is developing fast. Machine-made sand is used widely. The sand & aggregate production lines, composed of crushers, sand-making machines and conveyors, are seen everywhere. Considering environment and technologies, two sand-making methods—by dry-process and wet-process, are gradually mixed with each other.
Chinese machine-made sand production is entering leaping development stage. As the domestic famous enterprise configuring aggregate production line, LM vertical roller mill becomes the focus of this field. LM vertical roller mill are widely used in aggregate plants, mines, metallurgy, building materials, roads, railways, water conservancy, chemical engineering.
The capacity varies from 50 t/h to 1000 t/h with granularity arranged and classified in terms of different demands. In the design of technological process, LM vertical roller mill cover less area and have advantages of high investment profits, good quality of finished products, low dust output because the crushing equipment and spatial layout are arranged rationally. The installation of advanced electric control operating system guarantees the smooth discharging, stable operation, high efficiency.
