Product Introduction

    Superfine mill, also known as superfine powder mill, is mainly composed of main machine, fan, superfine analysis machine, finished powder collector, bag dust collector and connecting duct. A new type of milling machine designed and manufactured by adopting the principle of fluid mechanics. In recent years, it has been used in the grinding of ore materials in the fields of metallurgy, building materials, chemicals, mining and other fields. Such as: quartz stone, limestone, feldspar, porcelain clay, gypsum and other non-flammable and explosive mineral materials with a hardness of less than Mohs 7 and a humidity of 6% or less. Note: The fineness of ultra-fine grinding material is generally 425 mesh (33 microns)-3250 mesh (3 microns).

    Superfine grinding principle

    In the ultra-fine powder mill main body grinding chamber, the grinding roller assembly is suspended on the grinding roller hanger through the cross arm shaft, the grinding roller hanger is fixedly connected with the main shaft and the blade holder, and the pressure spring is tightly pressed against the grinding roller by the tension rod. On the outer end of the cantilever of the bearing room, the crossarm axis is used as the support point, and the grinding roller is pressed tightly on the inner surface of the grinding ring by the spring pressure. When the motor rotates through the transmission device, the blade mounted on the blade holder It rotates synchronously with the grinding roller, and the grinding roller rotates around itself while rolling on the inner circular surface of the grinding ring. The analysis machine drives the analysis machine impeller through the motor transmission device. The rotation speed of the analysis machine determines the fineness of the powder.

    Superfine grinding performance advantage

     1. High output: Compared with other mills, the output of superfine mill can be increased by 30%. If the spring pressure is increased, the power will be increased, and the output will be higher.

     2. Excellent product: Ultra-fine grinding mainly grinds various mineral materials with Mohs hardness less than seven, and the finished product has a wide range of fineness, and the particle size can reach 0.613 mm (30 mesh). ), The particle size can generally reach 0.033 mm (425 mesh), and a small amount of materials can also reach 0.003 mm (3250 mesh).

     3. Energy saving and environmental protection: The superfine mill adopts an overlapping multi-pole sealed grinding device, which has good sealing performance, no pollution, and the dust removal effect fully meets national dust emission standards. It is a green and environmentally friendly grinding equipment.

     4. High cost performance: Compared with air mill, the energy consumption of the system is low. In addition, ultra-fine grinding requires less investment, high efficiency and fast recovery.
