Application of HLMX Ultrafine Vertical Roller Mill for Non-metallic Ore in Ultrafine Powder Processing Technology

At present, the market demand for non-mineral powder is increasingly strong, and the annual average growth rate of consumption of heavy calcium is nearly 9.5%. It is predicted that the annual demand for non-metallic mineral powder will still maintain a high growth rate in the next 10 years. In the pursuit of stable product quality and uniform particle size distribution, the market also has an urgent demand for energy saving and consumption reduction in the processing of non-metallic mineral powder products, and also puts forward higher requirements for production equipment. Chinese mill manufacturing enterprises have also kept up with the pace of  technological development in the world, and developed a new type of domestic ultra-fine vertical grinding mill equipment for non-metallic minerals that is more suitable for the market. HCMilling(Guilin Hongcheng) HLMX series ultra-fine vertical grinding mill equipment for non-metallic ore is one of the high-quality equipment.

China’s large-scale and industrialized ultra-fine powder processing and ultra-fine crushing and fine classification equipment began after the reform and opening up. So far, the processing capacity, energy consumption per unit product, wear resistance, process matching and automatic control of China’s ultra-fine grinding technology and equipment have been significantly improved. According to the excellent performance of the vertical roller mill in the cement industry, it has become one of the ideal non-metallic ore processing equipment. It can well meet the requirements of reliable operation, large output, stable product quality and significant energy saving (30%~40% energy saving compared with the ball mill). However, the heavy calcium carbonate (referred to as heavy calcium carbonate) products produced by ordinary vertical mills are all 600 meshes (d7>23μm) The following can not meet the market demand for large-scale production of 1250 mesh (d=10um) ultrafine powder.

 

On the basis of the traditional coarse powder vertical mill, HCMilling(Guilin Hongcheng) has successfully developed the ultra-fine vertical grinding equipment for non-metallic ores by extending the eddy current ultra-fine classification system technology to the vertical roller mill industry and combining it with the vertical mill grinding system technology. The production system of ultra-fine vertical grinding equipment for non-metallic ore can process 325-2500 mesh ultra-fine powder, which can produce products with higher particle size with lower energy consumption. Compared with the ultra-fine vertical grinding mill in the same industry, HCMilling(Guilin Hongcheng) HLMX non-metallic ore ultra-fine vertical grinding mill equipment has the following advantages: lower cutting point of the classifier; The median diameter is smaller; The content of fine powder is higher; Higher yield; Lower energy consumption; The floor-station structure is adopted, and the installed area is smaller, which is 40% less than that of equipment in the same industry. The whole series is controlled by PLC. The sampling sensor involves temperature, rotation speed, air pressure, hydraulic pressure, vibration, amplitude, etc. The reliability, integration and ease of operation are guaranteed. Another advantage of ultra-fine vertical grinding equipment for non-metallic ore is that it can directly modify and activate the powder in production. Through special process design, strictly and quantitatively adding chemical additives and controlling the temperature in the mill, the chemical additives can be fully coated on the surface of inorganic non-metallic powder through repeated tests on the ultra-fine vertical grinding mill equipment of non-metallic minerals. The surface modification can be realized by directly adding chemical additives at one time without purchasing special modification equipment, which greatly simplifies the process flow and reduces the investment cost. The functional powder produced by this method is widely used in the artificial marble market of ultra-fine calcium carbonate.

 

At present, HLMX non-metallic ore ultra-fine vertical grinding mill equipment has been widely used in the processing technology of heavy calcium ultra-fine powder. It not only occupies the main market share in domestic heavy calcium enterprises, but also is exported overseas, and has been recognized by many large and well-known partners. In addition to the application in the processing of calcium carbonate powder such as marble and calcite, HLMX ultra-fine vertical grinding mill equipment for non-metallic minerals has also been successfully applied in the processing technology of non-metallic ultra-fine powder such as graphite, carbon, coal chemical industry, attapulgite, barite, graphite, steel slag, quartz, etc., providing good equipment support for the fine and high-value application of non-metallic mineral deep processing.
