Rock Grinding Equipment Surface Hardness

Hard turning and grinding are competing finishing processes for the manufacture of precision mechanical components such as bearings gears cams etc surface hardening at gentle machining conditions has often been reported and is attributed to strainstrain rate hardening and size effect

Mohs hardness 9 ferro alloys grinding machine china we are a largescale manufacturer specializing in producing various mining machines including different types of sand and gravel equipment milling equipment mineral processing equipment and building materials equipment

Notegrinding balls and media are sold on a per pound basis but attritors and dmqxmills are loaded by volume therefore the more dense the media the more pounds of media required for instance a machine requiring only 40 lbs of stainless steel may require up to 80 lbs of tungsten carbide

Whilst designed and used to determine the hardness of metal a new application in determining the compressive strength rock ucs and logging rock core sample has been researched this allows the equotip to be used as a rock strength testing machine without destroying sample ie nondestructively equipment
