Russia 400 tph river gravel crushing production line
River gravel as a natural stone, taken from the crustal movement experienced after thousands of years ago by the ancient riverbed gravel ridges produce mountains, experiencing the impact of flash floods, water removal process of continuous extrusion, friction. Tens of thousands of years of tremendous evolution, they tormented waves of water will sport collision friction is lost gravel irregular edges, and sediment has been a deep silence in the ground millions of years. Cobblestone main chemical composition is silicon dioxide, followed by small amounts of iron oxides and trace amounts of manganese, copper, aluminum, magnesium and other elements and compounds. They themselves have different colors, such as crimson by iron, copper blue by purple by manganese, yellow translucent stone colloidal silica marrow, emerald color with green mineral, etc; Because these ions dissolved dioxide pigment silicon hydrothermal different in type and content, thus showing shades, ever-changing shades of color, so that river pebbles showing a black, white, yellow, red, dark green, schungite other colors.

penalty clauses for high chrome grinding media balls
Circular vibrating sieve surface layers of two layers, the mesh size 5--100mm, up to 66-720 tons per hour processing capacity, motor power 22kw. Circular vibrating screen has reliable structure, strong exciting force, high screening efficiency, low noise and vibration, durable, easy maintenance, use of safety features, much of the industry users. Suitable gravel quarry screening material, but also for coal preparation, mineral processing, building materials, electricity and chemical industries for product classification purposes. The crushed material is discharged from the lower discharge port. Throughout under the crushing process, the material on their own mutual impact crusher, not in direct contact with the metal element, but the impact occurred and lining materials, friction and grinding, which reduces the pollution angle, mechanical wear extended time. Whirl ingenious internal cavity flow from circulation, eliminate the dust pollution. River gravel, is a hard, wear-resistant, chemical stability of silicate minerals, natural river eggs ore after crushing, sand, after screening a series of production and processing into egg river sand, river sand is an important egg industrial mineral raw materials. Widely used in water conservancy and hydropower engineering, highway, highway, railway, passenger line, bridges, airport runways, municipal engineering, high-rise building mechanism sand production and stone shaping. River pebbles to sand also widely used as concrete aggregate. River gravel resource-rich, relatively low acquisition cost and high value.
