The Development of Ball Mill has Impact on the Heavy Machinery IndustryThe development of ball mill equipment is closely related to the human technology progress, modern science and technology, and the overall industrial level, especially to the development of mechanical engineering science and mining subject. Modern science and technology has obvious time-domain, field and dynamic characteristics. Information science, materials science, life science, nanoscience, management science and manufacturing science are the mainstream science that will change the 21st century. The high-tech industry will change the world.Since the second half of 2011, the perlite production has become a popular investment industry. The original sand of the perlite by crushing and ultra-fine grinding can be used as a filler in rubber products, pigments, paints, inks, synthetic glass, insulation bakelite and fillers in some mechanical components and equipment. The perlite through expansion can become a light weight and multi-functional new materials. The perlite with light, apparent density and low thermal conductivity, chemical stability, wide temperature range, moisture absorption capacity of a small, non-toxic, odorless, fire protection, sound-absorbing characteristics is widely used in many industrial sectors.

It is understood that China’s Inner Mongolia and Xinyang have rich perlite. The perlite after being broken can be made into the insulation materials. Perlite ore includes perlite, obsidian and turpentine rock. The difference between the three is that the perlite has arc-shaped crack due to condensation, which is called perlite structure with 2%-6% moisture content. The turpentine rock has a unique luster of turpentine with 6% to 10% moisture content. The obsidian has a glass luster and conchoidal fracture, and the water content is generally less than 2%. Perlite was used as the insulation ans thermal insulation material for its thermal expansion characteristics in the earlier period for the industry. Perlite ore in China is very widespread, from Heilongjiang until Hainan Island, up to 3000 km along the volcanic belt. According to related statistics, the 65% application of the perlite is in the field of the construction projects, 30% is in the heat pipe insulation, and the rest is in decorative materials, many of which are the expanded perlite. From above, the development and application area of the perlite is extensive.
