Why FTM High-Pressure Grinding Mill ?

High-pressure grinding mill is suitable for various fields, such as calcium carbonate pulverization processing, gypsum powder processing, power plant desulfurization, non-metallic mineral powder production, coal powder preparation, etc. Common materials include limestone, calcite, calcium carbonate, dolomite, barite, talc, gypsum, diabase, quartz, bentonite, etc. The particle size of the micro-grinding product can be arbitrarily adjusted within the range of 80-325 mesh, and some materials can be as high as 600 mesh.

In the grinding chamber, the grinding roller assembly is suspended on the grinding roller hanger through the cross-arm shaft and the grinding roller hanger is fixedly coupled with the main shaft and the blade holder. The pressure spring is tightly pressed by the tension rod in the grinding roller bearing chamber. On the outer end of the cantilever, with the cross-arm shaft as the support point, the spring roller presses the grinding roller tightly on the inner surface of the grinding ring. When the motor rotates through the transmission device, the blade mounted on the blade holder rotates synchronously with the grinding roller, and the grinding roller rotates around itself while rolling on the inner surface of the grinding ring. The analyzer drives the analyzer impeller to rotate through the motor drive, and the speed adjustment of the analyzer determines the fineness.

Advantages

1. In the case of the same yield and fineness, the price of micro powder grinding mill is only one-eighth of the airflow mill, the scope of application is also larger, and the system energy consumption is only one-third of the airflow mill.

2. Compared with other similar mills, the micro powder grinding mill increases the crushing pressure of the material by 800-1200kg under the action of high-pressure spring.

3. The feeding size is large, and the one-time average particle size can reach 6.5μm.
