Important considerations when purchasing a jaw crusher The size of the opening into the crushing chamber. Two numbers, such as 24X36, commonly describe this. Where the opening between the top of the front and rear jaw plates is 24”, and the width between the side cheek plates would be 36”. The width number is directly related to the production capacity, while both numbers will provide guidance for what the maximum size of rock that can be fed to the crusher. Typically you would not want to feed the crusher rock that is larger than 90% of the maximum opening.
Gansu found three rare large independent scandium ore "In the newly discovered three scandium in the mine, only Sun Guling scandium 1, after a preliminary evaluation of the surface and a small amount of drilling control validation, proved reserves in more than 94 tons, circle the scandium ore article 51. In the process of mineral exploration, engineering and technical personnel developed suitable for this kind of mineral smelting and processing of mineral resources, to provide technical basis for the development and utilization of scandium ore resources in China." Responsible for the management review work of the Chinese academy of engineering soup neutral said.
1 - October 2013 the national mining equipment production presentation In October 2013, the production of mining equipment, 579500 tons, fell 10.46% year on year; October 1, 2013, the national special equipment of mine 5.4509 million tons, down 5.67% year-on-year.
New progress was made in golmud big ditch fe polymetallic census New progress was made in golmud big ditch fe polymetallic census. The second geological brigade to undertake the project by the provincial bureau of nuclear industry, in the exploration area identified five gold mineralization alteration zone, 2 to 5.2 km long, 1 to 10 meters wide, value 0.5 g and 0.5 g/ton. Through the five gold mineralization alteration zone engineering and verification, the current identified nine gold orebody, eight zinc ore body and 1 the copper body, at the same time delineating gold, zinc and copper () to the deep change in the width, the trend of the rich and accompanied by such as lead, silver polymetallic deposits. Preliminary project personnel think the area is looking for tectonic altered rock type gold deposit prospecting prospect, and in the future prospecting polymetallic attaches great importance to the periphery.

ZhongJi association of machinery industry development in our country Heavy machinery industry is an important part of the machinery industry, industry sales output value of nearly 1 trillion yuan in 2012. Sales value account for 5.5% of the mechanical industry. Products including mining machinery, metallurgical machinery, heavy forging machinery, material handling, lifting transportation machinery and equipment and major technical equipment required for manufacturing large castings and forgings, a total of 21 categories of more than 4200 varieties. Mainly for the mining, coal, steel, non-ferrous metal, electric power, petrochemical, port and ships, aerospace, energy, transportation, raw materials products and major technical equipment for basic industries. In recent years with the improvement of peoples living standard, some products are also directly to the consumption field service (passenger ropeway, mechanical three-dimensional parking equipment, etc.).
Ball mill outlook open efficient will be the development direction With the development of mining industry in China, more and more is also high to the requirement of grinding equipment, especially the ultrafine grinding. When the ore resources more and more access to all walks of life, of the ball mill this shearing section.at fine technology will bring a big change building materials industry. And this change will greatly promote the development of ultra-fine powder processing technology in China. In addition, some of our country mining machinery of large enterprises spend a lot of money every year to develop our own powder processing application and research aspects of the product. Especially in recent years has become a scientific research institutions and professional companies the main attack direction in the development and research.
