Technical field
The utility model relates to a kind of airslide disintegrating mills, more particularly, to a kind of using itself material as the compound of moving gaseouse medium Type superfine powder airslide disintegrating mill.
Background technique
Airslide disintegrating mill is also known as airflow milling, it is the high-speed flow sprayed using nozzle, particle is made mutually to impact, collide, It rubs (three main broken modes) and realizes the equipment that material fining crushes, the generally powder by partial size less than 10 μm is known as super Fine powder, it is widely used in the nonmetallic minerals such as coal, ceramic raw material (such as aluminium oxide, zirconium oxide), superhard diamond With the ultra-fine grinding of silicon carbide, metalliferous mineral powder, medicine, health food etc..It is continuous with development in science and technology and industrial requirement It improves, the requirement to properties of product is also higher and higher, and the demand of granule size has arrived at " micron " even " sub-micron " grade Not, and require that size distribution relative narrower, particle surface are smooth, grain shape is regular, with high purity, active big, dispersibility Well equal excellent performances, and airflow milling technology (also known as airflow pulverization) development in China cannot fully meet requirements of work at present The growth requirement of industry and technology.
Research of super-pine crush equipment is broadly divided into four kinds by its different grinding mode: to spray formula airslide disintegrating mill, flat gas Stream mill, target formula airflow milling and circulating airflow milling.
