Since the mid-1990s, with the development of new wear-resistant materials and the continuous improvement of vertical grinding technology, developed countries such as Germany and Japan have taken the lead in using vertical mill to grind slag and achieved success. Compared with other grinding systems, slag vertical mill integrates drying, grinding and powder separation together, which has the advantages of simple system and high efficiency. For grinding materials with high moisture content, there is no need to set drying equipment. Therefore, the investment and maintenance cost of the system is low, the operation reliability is high, and the grinding power consumption is low. The unit power consumption when grinding 420 m2/kg slag powder with specific surface area is about 40-45 kWh/t, and the shape of grinding products is better than that of other grinding systems. Therefore, under the same specific surface area, the product performance is better. Over the past decade, the application shows that slag vertical grinding mill is a mature and advanced slag grinding technology.

Cone crushers are often used for medium and fine crushing operations, and can process various ores and rocks with Platts hardness f ≤ 5-16 and medium hardness. This machine is divided into three types of crushing cones: coarse crushing, medium crushing and fine crushing. There are a variety of crushing cavity types to choose from. Normally, the standard crushing cone is suitable for medium crushing; the medium crushing cone is suitable for medium and fine crushing; the short head type is suitable for fine crushing.
