The 5 Best Pepper Mills of 2023 Tested by GearLab

2023年8月23日 The Kitchen-Go Grinder is basic, with a glass peppercorn holder that screws onto a steel base containing a ceramic grinding mechanism. We appreciated the large opening of the glass jar, which makes filling it a bit easier than some of the taller and narrower models. The grind size adjuster is on the underside and produces a fine to semi

Effects of impact and attrition mechanisms on size

2021年10月1日 On the other hand, the impact mechanism was found as more influencing within the coarser range therefore the product of ball mill was finer in that region. It can be stated that the impact and attrition mechanisms have different zones of efficient operation hence intersection is observed for the same grind size.
