Rod mills are frequently used as primary mills to produce suitable feed to the second grinding stage. Rod mills have usually a length/diameter ratio of at least 1.4. 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).

Cement mill separator, or cement separator, is a type of equipment that was widely used in the cement grinding system and raw mill system of cement plants.The function of the separator is to separate the fine-sized particles from the coarse-sized particles, so as to avoid material condensation and over grinding in the mill, and improve the milling system's grinding efficiency.

Influences of coal type, air rate and roller load pressure on the classifier operation are investigated. Abstract In order to investigate the classification performance of static air classifier in an industrial Vertical Spindle Mill (VSM), sampling ports were drilled on the mill shell and new on-line sampling methods were designed.

hardness of the grains; the feed roller supply and water quantities are regulated accordingly. As such, consistent milling results are ensured, irrespective of variations in raw material quality. Furthermore, the temperatures and volume flows of steeping and mashing water can be parameterized between 5–40 t/h. Thus,

A roller mill (1) including a housing (2) having a milling-material inlet (3), at least one milling-material outlet (4), and at least two cambered rollers (5, 5′) which are each arranged in the housing (2) so as to be rotatable about a roller axis (6). At least one roller (5) is assigned a scraper (7). The scraper (7) has a blade (8) for scraping milling material from a roller surface …

The efficiency of the basic Roller Mill System becomes a highly efficient means of removing moisture from the raw material by the simple addition of an air heater (G) as shown in color. Further refinements to the heater system allow the Williams Roller Mill to process hazardous dusts in a controlled low oxygen atmosphere.
