The philosophy in the development of the MRRC grinding simulation package was to build interactive software that could be used as an inexpensive means of providing a semi-quantitative check on a grinding mill design. In addition the software is designed to "slot in" to a general mineral processing package now undergoing …
Grinding Ball Design
Mill performance is affected strongly by ball design and properties. Mill performance and operation costs can be improved by selection of balls most nearly optimal for a given grinding circuit. Large variations exist between balls produced by various manufacturers and between production lots of balls.
The Best Countertop Grain Mills and Flour Grinders in 2023
The mill comes with a limited lifetime warranty from Victoria, covering craftsmanship defects for life from the date of purchase. The Victoria is an economical hand mill best suited for grinding dry grains and legumes into coarse meal and flour, but it won't produce fine pastry flour. Home brewers love it for grinding barley malt, as well!
