China has a vast territory and rich minerals. The development and utilization of ores is an enduring heritage of China for 5000 years. Contemporary ore processing mainly uses different grinding equipment to grind minerals with different properties, so that the ore is widely used in all walks of life. Since the introduction of pulverizer technology in the 1950s, it has become more and more mature, and the pulverizer market is becoming more and more saturated. Under the baptism of environmental protection storm, pulverizer manufacturing enterprises strive to improve, solve the problems of dust and energy consumption, follow the concept of social environmental protection and sustainable development, and become a new field of high-efficiency and low consumption pulverizer. Raymond mill is one of the equipment for ore grinding. Raymond mill with different parameters can apply ores with different hardness and humidity. It is a grinding equipment with high adjustability, flexibility and wide application range. It has gradually opened up the market in the fields of chemical industry, construction and medicine. It is believed that with the improvement of grinding equipment technology, its application market will be broader.
