Methods for processing feedstuffs before analysis can affect analytical results. Effects of drying temperature (corn silage), preservation method (corn grain), and grinding method (corn silage and grain) on starch analysis values were evaluated. Corn silage samples dried at 55 or 105 C and grain samples dried at 55 C were ground to pass the 1-mm screen of an abrasion mill or cutting mill and ...

Read MoreAug 15, 2001 Material initially ground through a 5 mm mesh was sieved through a 1 mm hand sieve commonly used for sieving soil samples. This served to remove all material smaller than 1 mm. The proportion smaller than 1 mm was recorded, as this was assessed to be an important grinding characteristic of the forage.

Read MoreMills and grinders are used for to break dry or wet samples into smaller particles by grinding, crushing, or cutting. Blades are used in mills to cut up samples into finer particles. Hand-held and bench top homogenizers blend chemical or biological samples thoroughly using various methods.
Read MoreLaboratory Mill. Laboratory mills, used primarily for sample prep prior to analysis, use particle size reduction (comminution) to grind or homogenize wet, dry, hard, soft, elastic, brittle, and fibrous materials. Mills and grinders are used in labs in widely varying scientific areas, including chemistry, pharmaceuticals, food analysis ...
Read MoreTissue grinders disperse and disrupt small tissue samples by being repeatedly pressed or squeezed between two hard surfaces. Usually, one surface is concave-shaped (the mortar) and other convex (the pestle). The mortar can also be shaped to the geometry of the test-tube, in which case the pestle is tight fitting with a clearance of 0.1 - 0.2 mm between the inner walls of the test tube and the ...
