Grind Retention - Is it a big deal? – Clive Coffee

04/10/2018  All in all, the extent to which grind retention matters to you depends on your preferred grinding routine, and how often you’re making drinks. For those that wish to single dose choosing a grinder often involves balancing the benefits of larger burrs and motors with their requisite increase in retention. For those that use timed dosing it’s simply a matter of understanding the amount of ...

Grinding/Milling/Dispersing Ceramic Beads Grinding Beads

The grinding beads should be 2 – 3 times larger than the separator or filter of the mill (e.g. slotted sieve, sieve cartridge, friction gap). The grinding media should be at least 5 times smaller than the distance between agitator disc and grinding vessel wall. The size of the grinding media should be approx. 20 to 30 times larger than the particle size (d 95) of the grinding product at the ...

Grinding Dispersing

tion, the bead retention screen is kept clear of the grinding media by the rotor of the separation system, thus preventing bead compression and blockage. A displacement device in the slotted pipe increases the fl ow speed in the outlet area and, in conjunction with short pipe-lines, prevents product entrainment. Optional cooling of the displacement device lowers the temperature of the product ...

Metallographic grinding and polishing insight

To obtain a high, consistent material removal rate, short grinding times and maximum flatness, totally fixed grains with a relatively large grain size are preferred for plane grinding. Suitable PG surfaces will provide perfectly plane specimens, thus reducing the preparation time on the following fine grinding step. In addition, some surfaces can provide good edge retention. During wear, new ...
