Mill Critical Speed Calculation | |

Estimates the critical speed of a grinding mill of a given diameter given the
mill inside diameter and liner thickness. If given a measured mill rotation (RPM), then the mill`s fraction of the critical speed is given | |

Size Analysis Graph | |

Calculate a new size analysis for testwork results.
Accepts cumulative % passing, cumulative % retained or the retained weights of a sieve series analysis. Results may be graphed in either a Rosin-Rammler, Schuhmann plot or Linear-Y axis and particles sizes may be expressed either in microns or mesh/inches. | |

Internet Slide Rule | |

A working web-based version of history`s most used
advanced calculation device. Available with 1 to 4 cycles and a
special Metric to Imperial conversion scale. | |

Pipe Launder Design | |

Determines the flow through a pipe
launder of a specified geometry. | |

Mill Liner Effective Thickness | |

Determines
the effective mill inside diameter of a given set of "top hat" lifters
for use in mill volume and critical speed calculations. | |

Mill Filling Calculation | |

Estimates
the charge volume of a grinding mill based on the number of exposed
lifters. By counting the number of lifters showing (during a mill
shutdown) and comparing to the total number of lifters (including those
buried in the charge) the fraction of the mill under the charge is
determined. |
