Iron ore is an important raw material of steel producers.After crushing, grinding, magnetic separation, flotation, re-election and other procedures,natural minerals

Copper ore, hardness of 3-4, copper ore after smelting commission becomes refined copper and copper products. Concentrate copper ore species

Magnetite ore is a significant ore of iron, it is black or brownish-black with a metallic luster, has a Mohs hardness of 5–6 and a black streak. Magnetite ore beneficiation process is divided into crushing, grinding, classification, magnetic separation, dry tailings discharge, three phases.

Quartz main ingredient is silica, Mohs hardness 7, translucent or opaque crystals, generally white.Quartz according to the quality can be classified of ordinary quartz sand, fine quartz sand, high purity quartz sand and fused silica sand. Quartz stone production line is divided into ordinary quartz sand quartz sand and refined quartz sand. General quartz sand specifications: 6-10mm ,10-20mm ,20-40mm ,40-80mm ,80-120mm, 120mm, 200mm, 260mm, 325mm, 600mm.

Calcite Mohs hardness is 3, calcite belongs to easy to grinding ore type, calcite milling generally require ultrafine calcite powder fineness, therefore, calcite is generally use fine powder grinding mill machine to grinding. Calcite mill general finished size range is 325-2500 mesh, production capacity is about 900-6000 kg/h or so.

The main mineral component of limestone is calcite. It has rare crystal structure and mineral particles and its surface is smooth and granular. Colors are black, gray, white, yellow and brown. Limestone containing seawater formation lime, hence the name of marble, limestone, chalk, rock, etc. Their main component of natural mineral is calcium carbonate.

Basalt main component is silica, aluminum oxide, iron oxide, calcium oxide and magnesium oxide. Common basalt is black, dark brown or dark green. Because of its dense texture, its specific gravity is heavier than granite, limestone, sandstone, shale. There is also light porous basalt, called "pumice."

Coal is very important energy source, and also an important raw material for metallurgy and chemical industry, there are lignite, bituminous coal, anthracite coal, semi-anthracite. When the coal seam close to the surface, it’s called open pit mine and about 40% of world coal production use pen pit mining. Seven largest coal reserves countries are the United States, China, Australia, India, Germany, South Africa and Poland.

Zhengzhou DMAC Machinery Co., Ltd. manufactures various equipments for whole set of sand-making production line

DMAC Impact Crusher Crusher is widely used in building materials, chemicals, coal and other industrial sectors, for coarse, medium and fine crushing medium hardness brittle materials, such as limestone, dolomite, shale, sandstone, coal, asbestos, graphite and rock salt, etc. Performance advantages crusher: 1, large crushing ratio, usually 10-20, high up 50-60; 2, simplified crushing process, simple structure, easy to manufacture; 3, and the ability to use and easy maintenance make a choice of broken and so on. 4, but due to the concentration of wear plate hammer, limiting the application of the crushing hard materials.

DMAC Vertical Impact Crusher VSI saving impact crusher is the introduction of New Zealand's advanced technology, combined with China's sand industry standard design, the current leading position in the country, is the fourth generation of energy-efficient sand making equipment. Mainly applicable to high-speed railways, highways, hydroelectric dams, concrete mixing station, refractories, metallurgy and building materials industries, is the ideal equipment for artificial sand and gravel integer.
