WhatsApp: +86 18203695377Our RMS 4 roller mill for preground malt has recommended starting gaps set to 4 thouhs of an inch (.102mm), and 3 thouhs of an inch (.076mm). From those starting points we adjust the mill to achieve the desired particle size. While the mill gap is the adjustment made, it is more important to measure the resulting grist.
WhatsApp: +86 18203695377Using a standard 2roller homebrew mill, I crushed each malt using four different gap settings. The gap settings were mm, mm, mm and mm, and I used a feeler gauge to confirm these gap setting between each milling. After milling, I performed a grain sieve test on the different malts and crushes, and recorded all of the results.
