The main link of the stone-paper making process is limestone-grinding; it directly affects the toughness, waterproof and anti-oil of stone paper. Limestone grinding equipment includes raymond mill, high pressure hanging roller mill, vertical milling machine, European mill etc. Hongxing mining machinery analyses the development trends and market demand of domestic milling industry, learns from Sweden's state-of-the-art technology of milling industry, according to the fineness requirements of grinding limestone and develops a new type of ultra-fine grinding equipment-- stone grinder machine.
In addition, the stone grinder machine has the following features:
1, low investment costs. In the case of equal fineness, it has less input, lower cost and shorter recovery period than jet mill.
2, high extraction rate. In the case of same finished product fineness and power consumption, its production is higher than that of jet mill and mixing mill by 45% or more.
3, low loss of vulnerability. All wearing parts are made of high quality wear-resistant materials, it makes the wearing parts have longer service life than ordinary mill equipment.
4, safe and reliable operation of grinding cavity. There is no problem of bearings and seals wearing because grinding cavity is without rolling bearing and screw, avoiding screw loosing easily and destroying the machine.
5, high finished product fineness. The final fineness can reach d97 ≤ 5μm once.
6, zero environmental pollution. It adopts efficient pulse dust collector so that the entire device would not cause dust pollution during operation; it is configured with muffler and silencer room to reduce noise and organizes production in full accordance with national environmental standards, playing a role in environmental protection.
