Sandstone is used for grinding wheels because of its abrasive properties, allowing it to effectively grind and sharpen materials. It is a durable material that can withstand high pressure and heat generated during the grinding process. Additionally, sandstone provides a smooth and consistent surface for precise and efficient grinding.
Usually a synthetic material is now used. Carborundum is made from silicon carbide. A composite of silicon carbide and aluminum oxide is better. In the days of the old windmills and water driven mills, for grinding cereal grains, a hard stone called millstone grit was used.
Abrasives are used in sandpaper, grinding wheels, traction strips, polishing compounds. They allow you to smooth, cut, shape, or polish items. Or, they promote friction such as keeping one from falling on slippery surfaces.

Maybe marble or basalt, or granite which could be used in a mortar and pestil device. Actually any hard rock could be used for this purpose. In the olden days, limestone slabs were formed into grain grinding mill wheels, and wheels of sandstone were rotated by hand or foot on an axle to grind metal tools to a sharp edge.
Adding sand and anhydrous magnesium sulfate before grinding leaves helps in two key ways. The sand assists in physically breaking down the leaf material, increasing surface area for better extraction of compounds. Anhydrous magnesium sulfate acts as a drying agent, absorbing any moisture, which ensures that the extracted compounds remain in a suitable form for effective chromatography. This combination improves the efficiency and clarity of the chromatographic separation.
quartz-based silica sand used in sandpaper, glass grinding, stone sawing (as in dimension stone manufacturing), metal polishing and metal casting cleaning, and in sandblasting to remove paint, stain, and rust.
Grinding wheels have many different types and purposes. They are used to sharpen tools, as well as, for removing rust and paint for a smooth surface.
They pick up bits of sand or little pebbles to serve as a grinding stone in there Gizzards. (a gizzard is an enlarged muscle in a duck's stomach, used for churning and grinding up food)
sand stone is use for building houses with
Gemstones, sandpaper, and Grinding wheels. Hope this helps. :)
Corundum can be used for sandpaper,jewelry,grinding wheels,etc.
Lime stone and sand stone.
Jt is used for many things. Glass is made from silica. Sand is used in making concrete and mortar, and as an abrasive (grinding) agent.
it is used for building houses
Alumina, which is derived from bauxite ore, is commonly used to make grinding wheels. It is often combined with other materials, such as silicon carbide, to enhance the hardness and durability of the wheel. These grinding wheels are essential in various machining processes for shaping, sharpening, and finishing metal and other materials.
The English name of "Aatukallu" is "grinding stone." It is a traditional tool used in various cultures, particularly in South India, for grinding grains and spices. The stone typically consists of a flat surface and a cylindrical stone used to grind ingredients against it.
Sandstone has been used in sharpening devices, grinding wheels, grain mills, building cladding, monuments, countertops, and as a source of silica sand for masonry, tool making molds, production of tiles, bricks, blocks, and pavers, and glass production.
