Since the beginning of the 21st century, the demand of mining machinery market is strong. The relevant data shows that the growth rate of mineral powder products in China is stable between 35% and 46%. Market demand not only drives the economic growth of mining machinery manufacturing industry, but also directly promotes the technical development of the whole industry, and a batch of large-scale advanced products with independent intellectual property rights emerge. SBM ultrafine mill is one of the industry application model equipment.
According to the modern market demand, the large-scale of high-tech equipment is one of the development trends of mining machinery. The expansion of domestic mine development scale requires the large-scale equipment specifications. The small size of the ultra-fine grinding machine is hgm80, with a volume of about 13.9x4x6.2 (m). The model is hgm1680, with a floor space of 26.3 * 7.5 * 11.9 (m). Successful realization of large-scale production equipment requirements.
One of the requirements for users to purchase equipment is resource-saving process and equipment, including energy utilization rate, consumption index of equipment wear-resistant materials, water and electricity consumption index of equipment processing, etc. These requirements can not only reduce the cost of production, but also meet the national requirements for modern large-scale mechanized production. In the research and development of ultra-fine grinding machine, SBM adopts pulse dust collector to capture dust and muffler to reduce noise, which has the characteristics of environmental protection and cleaning. In the case of the same fineness of the finished product and the same power of the motor, the output of the mill is more than twice that of the air flow mill, the stirring mill and the ball mill. The grinding roller and ring in the grinding chamber are forged with special materials, which can last for more than one year. When processing calcium carbonate and calcite, the service life can reach 2-5 years.
According to the needs of customers in recent years, the needs of customers in processing equipment technology and personalization are gradually emerging. The new two-stage interleaving processing technology is adopted in the ultra-fine grinding mill, the main shaft passes through the upper stage rotary table and the lower stage rotary table; the upper stage rotary table and the lower stage rotary table drive the upper stage grinding roller and the lower stage grinding roller respectively through the upper stage roller pin and the lower stage roller pin, and make the rotary motion in the ring of the upper stage grinding ring and the lower stage grinding ring. The new-type two-stage interleaving ultra-fine grinding machine can distribute energy reasonably, improve production efficiency and save energy more. The practice shows that the fineness distribution of the finished product is more uniform.
