Table 2 shows, as an example, the advantages of the eccentric vibratory mill in comparison to a conventional tubular vibratory mill for ultrafine grinding of limestone. With the eccentric vibratory mill 6562ks, the throughput can be raised by a factor of 2 at half the grinding chamber volume of the doubletube vibratory mill.

The heart of a grist mill was its grinding stones. Grinding stones were used in pairs. The bottom stone, or bed stone, was fixed into position, while the upper stone, or runner stone, moved. The stones were connected to the power source (water or wind) by a wooden "counterwheel," or contrate wheel, wedged on the horizontal drive shaft, which ...

Tube Mills. Tube mills are in principle to be considered as ball mills, the basic difference being that the length/diameter ratio is greater (3—5). They are commonly used for surface cleaning or scrubbing action and fine grinding in open circuit. Pebble Mills. In some cases it is suitable to use screened fractions of the material as grinding ...

The energy consumption of the total grinding plant can be reduced by 2030 % for cement clinker and 3040 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended.

4. Grinding process. In the ball mill, the material is mainly crushed by impact and friction. In the vertical grinding mill, the material is mainly extrusion, and grinding is the auxiliary. The residence time of the material in the vertical mill is 23 minutes, while in the ball mill it takes 1520 minutes.

The design and the motion behaviour of the filling of a new centrifugal tube mill are introduced. In contrast to the usual range of application for centrifugal tube mills, once developed to substitute ball mills, it is shown that centrifugal tube mills are particularly suited for pulverizing if the grinding media filling is reduced to max. 35%. This measure also reduced the connected load by ...
