Basalt Mineral is a dark-colored, fine-grained, igneous rock composed mainly of plagioclase and pyroxene minerals. It most commonly forms as an extrusive rock, such as a lava flow, but can also form in small intrusive bodies, such as an igneous dike or a thin sill. It has a composition similar to gabbro. The difference between basalt and gabbro is that basalt is a fine-grained rock while gabbro is a coarse-grained rock.
Basalt ore underlies more of Earth’s surface than any other rock type. Most areas within Earth’s ocean basins are underlain by basalt. Although basalt is much less common on continents and islands, lava flows and flood basalts underlie several percent of Earth’s land surface. Basalt is a very important rock.
Basalt is used for a wide variety of purposes. It is most commonly crushed for use as an aggregate in construction projects. Crushed basalt is used for road base, concrete aggregate, asphalt pavement aggregate, railroad ballast, filter stone in drain fields and may other purposes. Basalt Ore is also cut into dimension stone. Thin slabs of basalt are cut and sometimes polished for use as floor tiles, building veneer, monuments and other stone objects.
Basalt is used in construction (e.g. building blocks or in the groundwork), making cobblestones (from columnar basalt) and in making statues. Heating and extruding basalt yields stone wool, an excellent thermal insulator.
The chemical composition of mid-ocean ridge basalt ore, the most prevalent magma type on the planet, reflects the melt’s continuous reequilibration with the surrounding mantle during porous flow. Models of basalt extraction that account for the observed uranium-series disequilibria on the Juan de Fuca ridge constrain both the abundance of melt beneath ridges (0.1 to 0.2 percent) and the style of mantle melting. Unlike models that incorporate near-fractional melts (dynamic melting), mixing of equilibrium porous flow melts derived from heterogeneous source materials quantitatively explains the uranium-series observations.
Based on years of production experience, we absorb technology advantages from the same field abroad and domestic, organizing elite basalt crushing experts to investigate, research, try again and again; finally, we develop CCM basalt crusher and basalt grinding machine.
Our basalt crusher includes 4 series: jaw crusher series, cone crusher series, impact crusher series and mobile crusher series, of which cone crusher series and mobile crusher series have better performance. The basalt cone crusher friction disc design and rotation of eccentric shaft bushing around fix cone plus more reasonable "labyrinth seal" system are unique features, which have more advantages like easier operation, larger application scope, more reliable, more smooth functioning comparing with traditional basalt crusher. It is the most ideal equipment as basalt crusher.
In the above basalt crushing plant, the main difference is the secondary basalt crusher: using impact crusher, or using fineness Jaw crusher, or Compound cone crusher. For Jaw crusher and compound cone crusher, the working principle is plate pressing, so the percentage of stones with flaky shape, internal cracks is high. For impact crusher, it has the functions of crushing and shaping, can make very good cubic shape; the stone materials are mainly used for highway, water conservancy, airport, civil construction etc.
