A hard, coarse-grained siliceous sandstone; as, millstone grit; -- called also gritrock and gritstone. The name is also applied to a finer sharp-grained sandstone; as, grindstone grit.
Structure, as adapted to grind or sharpen; as, a hone of good grit.
To give forth a grating sound, as sand under the feet; to grate; to grind.
To grind; to rub harshly together; to grate; as, to grit the teeth.
The texture of a nail file ranging from coarse, medium, to fine. Glossary
Small pebbles and stones used in a bird's gizzard to aid in the breaking down of food. Birds can't chew because their only mouthpart is their beak; therefore, they must use grit - along with the strong crushing muscles in the gizzard - to grind up ingested food.
A term most commonly used to describe the fineness or coarseness of “sandpaper†and other abrasive materials. This degree of coarseness is ex-pressed by a grit number.
Hard and heavier solid matter removed from wastewater, generally inorganic.
In relation to pesticide formulations, hard non-friable particles present in a material.
Small pebbles fed to birds to help them grind up their food.
Gravier Staub, m Gravilla Not fine sand but coarse gravel used to air the soil.
Sand, gravel and heavy inorganic material from wastewater removed to prevent accumulation in basins and tanks and damage to downstream pumping equipment. After removal, grit is dewatered and landfilled.
Sand and soil particles in dried fruit which make the fruit objectionably gritty to eat.
A granule used in sandpaper or as a blasting media.
the measurement of the coarseness or smoothness of sandpaper. The higher the grit, the more particles of grit per square inch, and therefore the smother the finish. Referred to as a number, (ie. 100 grit)
Any hard sandstone, especially one in which small pebbles are mixed with the sand to give a rough texture suitable for millstones. Also known as gritstone.
coarseness of texture in sanding papers or powders.
crushed stone or sand placed in clay in order to make potter vessels stronger
Grinding powders, silicon carbide (SiC) or aluminim oxide ( Al2O3). Stephen Tonkin maintains information on abrasives (grits) at http://www.aegis1.demon.co.uk/abrasiv.html. His information includes the particle size related to various classification schemes and also the elutriative time. The times given are the time to settle in a 1m column of water.

small bits of rock, shell, or other hard substances that a bird swallows to aid in the digestion of coarse vegetable matter
Heavy, inorganic matter, such as sand or pebbles.
The heavy material present in wastewater, such as sand, eggshells, gravel, and cinders.
Fine, abrasive particles can be deposited onto a variety of hard surfaces including floors and walls.
The designation of size of an abrasive grain. The number is determined by the number of grains that fall through openings per linear inch in the controlled sieving screen.
Small pieces of rock, shell, or other hard substances ingested by birds to assist the gizzard in the process of digestion. The muscular action of the gizzard, together with the abrasive action of the grit, help martins grind down the hard, chitinous, exoskeletons of the beetles, dragonflies, and other insects they eat. A gizzard with its grit is analogous in function to a mammal's mouth having teeth for the purpose of food pulverization.
grinding agent used in digestion: sometimes needs to be added to their diet if not free range
Small pieces of rough diamond, used as industrial abrasives, may be natural or synthetic.
Hard and heavier solid matter in wastewater. It is generally inorganic. Examples include sand, gravel, ash, glass and metal fragments.
Insoluble stoney matter fed to chickens to allow their gizzard to grind their food up.
Abrasive obtained from slag and various other materials.
Bark, with small sand-like particles visible in slash; making a noise like metal on stone or sand when slashed. Parent Term: Bark_texture
Fine sand or gravel that is swallowed by birds and retained in their gizzards to grind up their food.
the heavy suspended mineral matter present in water or wastewater, such as sand, gravel, and cinders. b c
Sand and small pebbles eaten by chickens and used by its gizzard to grind up grain and plant fiber.
A measure of the roughness of an abrasive paper. The lower the figure given for the grit size, the coarser the paper.
Pertaining to the texture of the surface of the ball, whether polished or sanded.
A measure of the size of abrasive particles used in the manufacturing of sandpaper. Grit can also be measured as the number of particles in an square inch of sandpaper surface.
Natural mineral spreading medium consisting of particles of stone
very fine bits of gravel or sand in sharply angular particles; a coarse sandstone. [AHDOS
Mineral particles used for abrasive metal removal. A to C H to M N to R S to Z
Rough, hard, abrasive particles of sand or stone.
