The color of sandstone varies, depending on its composition. Argillaceous sandstones are often gray to blue. Because it is composed of light colored minerals, sandstone is typically light tan in color.
Other elements, however, create colors in sandstone. For crushing of sandstone, you can opt for the entire series Stark designed specifically to get finish product crushed and used in different contexts. Its heavy duty structure allows to obtain different grain sizes.
In addition to Stark Series, also the machinery of Crunch Series may become useful for crushing sandstone. Its horizontal axis free hammers allows to arrive at a secondary crushing of the high quality material, based on the grain requirement. Since Mec has successfully established itself in the splitting and processing of stone field.
Today Mec is present in more than 70 countries in the world with its powerful, high-precision and fully customizable machines. Hello, welcome to MEC. Magnificent sandstone outcrops in the state can be seen at Valley of Fire State Park. With a great deal of heat and pressure, sandstones turn to the metamorphic rocks quartzite or gneiss, tough rocks with tightly packed mineral grains. Actively scan device characteristics for identification.

Sandstones are rocks composed primarily of sand-size grains. Sandstone: Close-up view of the sandstone specimen shown above. The gray and white grains are mostly quartz, the black grains are particles of impure coal and shale, and the brown material is stained clay minerals that probably formed when feldspar grains in the sandstone were broken down by weathering.
The grains of sand in a sandstone are usually particles of mineral, rock, or organic material that have been reduced to "sand" size by weathering and transported to their depositional site by the action of moving water, wind, or ice. Their time and distance of transport may be brief or significant, and during that journey the grains are acted upon by chemical and physical weathering.
If the sand is deposited close to its source rock, it will resemble the source rock in composition. However, the more time and distance that separate the source rock from the sand deposit, the greater its composition will change during transport. Grains that are composed of easily weathered materials will be modified, and grains that are physically weak will be reduced in size or destroyed. If a granite outcrop is the source of the sand, the original material might be composed of grains of hornblende , biotite , orthoclase , and quartz.
Of these minerals, hornblende and biotite are the most chemically and physically susceptible to destruction, and they would be eliminated in the early stage of transport. Orthoclase and quartz would persist longer, but the grains of quartz would have the greatest chance of survival.
They are more chemically inert, harder, and not prone to cleavage.
