Although the mill grinds well, I often find myself using another grinder that can hold more beans in the hopper. I use a french press to make my coffee and it does a good job of grinding the course grind needed. I would give it a better rating if it had a bigger hopper with an easier load so the beans were not falling on the counter.

The "Critical Speed" for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface. This is the rotational speed where balls will not fall away from the mill's shell. Result #1: This mill would need to spin at RPM to be at critical speed. Result #2: This mill's ...
Penngecilan ukuran pada pengggerusan, grinding tergatung pada seberapa besar peluang dari partikel bijih untuk dapat digerus. Penggerusan terjadi oleh adanya beberapa gaya yang bekerja pada partikel bijih tersebut. Gaya-gaya yang bekerja pada operasi penggerusan adalah impact, kompresi, shear/chipping dan abrasion. Gaya-gaya ini akan mengubah bentuk partikel bijih sampai melampaui …
