Sandstone is formed by quartz grains and it has stable structure. In general, it shows the light brown or red and sandstone mainly contains silicon, calcium, clay and iron oxide. Sandstone is a sedimentary rock and it is mainly composed of sand consolidation, which has more than 50% sand grain content. The vast majority of sandstone is composed of quartz and feldspar. Main ingredients: quartz content is more than 52%; Clay is around 15%; Goethite is by about 18%; other substances are by more than 10%.
The sand and sandstone can be used as raw materials and building materials, abrasives, glass; and it is the most widely used a stone building.
According to the classification of rock types: quartz sandstone(quartz and a variety of siliceous rock debris content over 95% of the total level of sand rock debris) and unpurified quartz sandstone, feldspar sandstone (clastic composition are mainly quartz and feldspar, quartz content lower than 75%, feldspar by more than 18.75%) and feldspar sandstone, lithic sandstone (detrital quartz content lower than 75%, lithic content is generally greater than 18.755, the cutting/feldspar ratio greater than 3) and lithic sandstone.
In the world, the exploitation and utilization of sandstones have: sandstone with Australia, Indian sandstone and sandstone in Spain, China sandstone, etc. Among of them, the Australia sandstone is the most popular and welcomed for its color and decorative pattern. Australian sandstone is a kind of ecological environmental protection stone material which has the following characteristics: no pollution, no radiation, no reflective, weathering, color, heat, and heat preservation, prevent slippery.
In sandstone crushing plant flowchart, SBM recommends you to adopt the equipment which mainly includes jaw crusher, impact crusher, vibrating feeder, vibrating screen and belt conveyors and the sand making machine-vertical shaft impact sand making machines.
The whole sandstone crushing plant also has the other stages and machines: sandstone beneficiation. The magnetic material content can determine the level of quality throughout the mine, so the beneficiation before the sandstone quarrying is very important. Besides, the location and transport also need to consider.
Depending on the above sandstone crushing plant flowchart, we can see that it needs some crushers in the whole processing line. SBM will provide the high quality sandstone crushers for you all: jaw crusher, cone crusher, hydraulic crusher, impact crusher and the mobile crushers.
The cost effective sandstone crushers are widely used in mining, concrete factory, sandstone making, etc. And they are widely suitable for primary crushing of many kinds of ores, concrete, fireproof material, bauxite, basalt and so on. Comparing with other kinds crushers, sandstone cone crusher has excellences for the fine crushing, high productions, and low maintenance. The long force arm designed into the machine provides greater crushing force.
Sandstone cone crusher with high-efficiency and hydraulic pressure is widely used in mining, concrete factory, sandstone making, etc. The machinery's pressure resistance strength is under 350 Mpa. And they are widely suitable for primary crushing of many kinds of mining and rock such as many kinds of ores.
This cone crusher consist of frame, transmission device, hollow eccentric shaft, bowl-shaped bearing, crushing cone, springs and hydraulic pressure station for adjusting discharge opening. During operation, the motor drives the eccentric shaft shells to turn around through a horizontal axle and a pair of bevel gear. The axle of crushing cone swings with the force of eccentric shaft shell so that the surface of the crushing wall is close to the roll mortar wall from time to time. In this way, the ores and rocks will be pressed and crooked and crushed.
Besides the auxiliary equipment for sandstone crushing plant, it also needs the auxiliary equipment. The most widely used auxiliary equipment includes: feeding machine, screening equipment and conveying machine. According to clients' production needs, the vibrating feeder, belt conveyor and vibrating screen are the most suitable equipment.
SBM designed the YKN series vibrating screen, which has high-strength exciting force.
Mobile crushers are loaded on their own crawler tracks or towed by truck horse when transported over longer distances to a new location.
Spiral classifiers are designed to provide the most effective pool area and overflow velocity requirements.
Vibrating screen is suitable for the moist , fine grain and hard screening material dry screening in mining industry.
