Blast furnace slag is being broken by crushing equipment and additional grinded from the key grinding mill. Blast furnace slag crusher and grinding machine can also be widely used for crushing cement, Portland products, new building materials, refractories, fertilizers, along with black and non-ferrous metal processing industries including the production of glass ceramics, various ores as well as other materials could be grinding of dry or wet grinding .
Three Chinese contractors toppedInternational Construction's (iC's) 2012 ranking of the world's 200 largest construction companies for the second year running. The league table, which is based on revenues in 2011, saw China State Construction Engineering Corporation (CSCEC) overtake the country's two largest railway contractors to claim the top spot.
This series cone crusher plant adopts the electric motor as the power. The eccentric shaft is revolved by an electric motor through v-belts, which causes the swing jaw moving in the preconcerted path to crush the feeding material. Thus the material will be crushed in the crushing chamber which is composed of the stationary jaw plate, swing jaw plate and the liner plate. The material will be discharged from the lower part of machine that is what you want. Aggregate jaw crusher runs and works in the similar process.
Two other Chinese contractors - China Communications Construction Group and China Metallurgical Group (MCC) were also ranked in the top 10. They were joined by Vinci, ACS, Bouygues and Hochtief from Europe, while Bechtel was the only US contractor in the top 10. The highest-placed Japanese construction company was Daiwa House at no.12.
Among the biggest climbers up the rankings were three companies involved in the petrochemical and oil & gas construction sector, including   JGC and Petrofac. Heavy fallers meanwhile included US residential construction companies D R Horton and Pulte Group, as well as Spanish contractors Sacyr and Ferrovial.
