Grinding Mill

The Handling Materials and Function of Grinding Mill:

Grinding mill is mainly applied to grind non-inflammable, non-explosive and brittle materials with Mohs hardness under six. Such as calcite, chalk, limestone, dolomite, kaolin, gypsum, talc etc, totally more than 100 kinds of materials. Product fineness can be controlled between 325~2500 mesh (47~5 micron).

The Performance Characteristics of Grinding Mill:

1. The plant is stable and highly automatic.

2. Inner lining and grinding media can be changed according to customers’ request, such as high manganese steel, silica, ceramics, etc.

3. Fine powder size is even and can be adjusted.

4. The system is low trouble rate, and can be operated continuously.

Advantages of Grinding Mill from Hongxing Machinery

1. Grinding machine has wide application ranges compared with airflow mill.

2. Compared with other grinding mills, the grinding force of the grinding roll of grinding mill is improved by 800-1200Kg under the high pressure spring.

3. Grinding machine saves more energy. When the output and the fineness are the same, the energy consumption of this system is only one third that of the airflow mill.

Inside the grinding room of the micro powder mill, the grinding roll assembly hangs on the cradle of the grinding roll through the corss arm. The cradle of the grinding roll, principal axis and the relieving tool post are fixed and connected and the pressure spring tightly presses on the outside end of the cantilever of the bearing room of the grinding roller through the tension bar. The corss arm bearing is the supporting point, and the grinding roll is tightly pressed to the surface of the inner circle of the grinding ring through the spring pressure. When electro motor rotates through the transmission device, the relieving tool on the relieving tool post and the grinding roll will synchronously rotate, and the grinding roll also rotates around itself while rolling on the surface of the inner circle of the grinding ring, and the analytical engine drives the impeller to rotate through the transmission device, and the adjustment of the speed of the analytical engine will determine the fineness of the final powders.
