How to crush slate stone, natural slate stone ? What can slate used to ? Let us introduce the slate:
Slates are dense and fine grained rock. The colour of slates are generally gray, red, brown and green ranging from dark to light. It is produced by the compression of clays, shale, and various other rocks developing a characteristic cleavage consisting sericite and quartz with biotite, chlorite, and hematite as principal accessories.
In other words slates are generally formed by low-grade regional metamorphism of pelithic sediments or fine-grained tuffs. It can be associated with other metamorphic sedimentary or volcanic rocks.
Slates are or argillaceous origin of metamorphic rocks and can also be defined as a layered stone. Fossils may be sometimes preserved in slate but are invariably distorted. Folds are often apparent in the field. Too fine-grained are tough to distinguished with the naked eye.
Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low grade regional metamorphism. The result is a foliated rock in which the foliation may not correspond to the original sedimentary layering. Slate is frequently grey in colour especially when seen en masse covering roofs. However, slate occurs in a variety of colours even from a single locality. For example slate from North Wales can be found in many shades of grey from pale to dark and may also be purple, green or cyan. Slate is not to be confused with shale, from which it may be formed, or schist.
Physical Properties of Slate
Physically these are Metamorphic-Argillaceous rocks, which has developed a well-marked splittable cleavages with or without developed recrystallization & spots/knots of minerals like garnet, pyrite, andulasite, etc. They are normally fine to medium grained, moderately hard & compact, less homogeneous with varying textures & shades. It has an ability to split into thin layers along the plane of cleavages due to flattened & elongated minerals along the plane of cleavage.
Chemical Properties of Slate
Chemically they are Multi-Mineral, metamorphic argilaceous rocks made of an aggregate of minerals and colloidal substances. Essentially mineral composition includes quartz, mica, chlorite, sericite & oxides of iron with occasional spots/knots of minerals like garnet, pyrite, andulasite, etc.
Uses of Slate
Paving, Stepping stone in garden, Combined with other materials gives quality and attractiveness, Square blocks for a break band in section of granite paving, Decorative clocks and thermameters, Picture frame, mirrors, coasters, trivets, switch plates, candle holders, Engraved and painted in jewellery like earrings and pins.
