Gabbro is a coarse-grained, dark-colored, intrusive igneous rock. It is usually black or dark green in color and composed mainly of the minerals plagioclase and augite. It is the most abundant rock in the deep oceanic crust. Gabbro has a variety of uses in the construction industry. Gabbro sometimes contains economic amounts of some relatively rare metals. Gabbros containing significant amounts of the mineral ilmenite are mined for their titanium content. Other gabbros are mined to yield nickel, chromium or platinum.
Color - dark grey to black.
Texture - phaneritic (medium to coarse grained)
Mohs hardness: 7-7.5
Silica (SiO2) content - 45%-52%.
Uses - as aggregate, fill etc. in the construction and roading industries; cut and polished for dimension stone (called black granite) for building facings, foyers etc.
Gabbro can be formed as a massive, uniform intrusion via in-situ crystallisation of pyroxene and plagioclase, or as part of a laminate as a combination intrusion formed by decantation pyroxene and plagioclase. Cumulate gabbros are more properly called pyroxene - plagioclase orthocumulate.
Gabbro is an essential part of the oceanic crust, and can be found in many ophiolite complexes as parts of zones III and IV (sheeted dyke zone to massive gabbro zone). Belts long gabbro is generally formed at proto -rift margins and around ancient rift zone, intruding into the flanks of rift zones. Assumptions of mantle plume can rely on identifying mafic and ultramafic intrusions and contemporary volcanic basalt.
In the process flow of Gabbro crushing line, vibrating feeder is the first used mining equipment to supply raw material to stone crusher machine. The primary stone crusher is jaw crusher or PEX jaw crusher whose aim is to make big stone smaller.
The secondary stone crusher is cone crusher. Cone crusher is a kind of crushing machine commonly used in mining, metallurgical industry, construction, road construction and chemical industry. Our cone crusher can be used to crush hard and medium hard minerals, rocks, iron ores, limestone, copper ores, quartz, granite, sandstones, etc. In a whole production line, usually, the cone crusher is used for secondary or tertiary crushing process, or first crushing. Cone gabbro crusher is the best machine to crush gabbro. The finished product is cubic, and of good quality, great strength to resist compression. With low contents of needle and slice particles.
The mobile crusher plant is widely used to match the crushing and sieving equipment in many industries including metallurgy, coal mine, mineral dressing, building material, chemical, grinding, etc. If you are looking for a mobile crushing plant for contracting with the ability to produce clean, precisely sized end products effectively, the track mounted mobile crushing plant is the answer. SBM's track mounted mobile crushing plant is designed to crush hard rock and any recycling materials equally effectively.
