01.06.2020Consistency is critical in whatever you are grinding: all the pieces of the grind should be about the same size. As for what that size should be, pieces of herb around the size of 1-2 mm square are ideal, although some pieces may be longer than that if they come from a leaf or fibrous plant as long as their short-side diameter is around that 1

14/11/2022Fine Grinders Using impact and attrition, fine grinders reduce materials until they are ground to a grain size level. Solid materials are broken down through mechanical forces, breaking up particles by overcoming internal bonding forces. Grinding not only reduces particle size but also changes the shape and nature of the particles.
