According damaged the mode of action can be divided into two categories of crusher forces: (1) crushing; (2) the. milling machine Crusher overall handling of multiple pieces of equipment, products and crude detail, typically 8 mm and more.The architecture features of broken piece is a specific difference between, do not touch each other.Crusher and can be broken down into the crushing computer, a broken machinery and thin computer.Generally speak the grinder processing material is excellent, the product has excellent particle size, can be as high as 0.074 millimetres, and even good a.The structure of divided regions (or average) contact with one another, this media gangqiu, iron line, grit or mineral blocking, and so on.But some computer has broken mine at the same time simultaneously and the impact crusher, such as grinding machines.For of 5.5 expand one.8 m from the grinding process the minerals the size reaches 350-400 millimeters, the finesse of goods 200 net 40 per cent or so. Most copper ore is mined or extracted as copper sulfides from large open pit mines in porphyry copper deposits that contain 0.4 to 1.0% copper. Examples include: Chuquicamata in Chile, the Bingham Canyon Mine in Utah and the Chinese Mine in New Mexico, US. The average abundance of copper found within crustal rocks is approximately 68 ppm by mass, and 22 ppm by atoms. In 2005, Chile was the top mine producer of copper with at least one-third world share followed by the USA, Indonesia and Peru, reports the British Geological Survey.
In the primary crusher, jaw crusher is the most popular machine, which features easy maintenance, low cost, high ratio, etc. In secondary crushing process and tertiary crushing process, hongxing has improved our CS Cone crushers and hydraulic Cone crushers capacity and end crushing products. The total energy consumption is reduced considerably. Comparing the operation efficiency of CS Cone crusher and hydraulic Cone crusher, we find CS Cone crusher achieved better results in tertiary crushing. And if installing the same number of secondary and tertiary crushers, a part of operation is transmitted from tertiary to secondary crushers where the liner wear is three times less, which significantly influences on the cost reduction in the crushing process. Mineral powder to the human body healthy and produces large damage, illness, such as pneumoconiosis silicosis, miners mining production such as pulmonary disease is the greatest threat to health, should seriously, and mine must take comprehensive dustproof steps.The workplace powder concentrations of pneumoconiosis disease in the development have played a crucial role, The Rock
