This series of jaw crusher belongs to stone crushing equipment which is widely used in the works of metallurgy, mining, cement, chemistry, refractory and ceramics as well as highway construction and water conservancy.
Roll crusher is a crushing machine researched and manufactured by our company for coarse crushing.
Spiral separators, which are also called spiral concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium.
An impact crusher is a piece of heavy construction equipment people can use to reduce the size of things like rock, waste concrete, and similar materials.
The ball mill is one of the most widely used super fine grinding machine in the industry and it is the key grinding equipment after materials have been crushed.

Direct reduced iron (DRI) process. In addition to the process route via the blast furnace process, there is another option for extracting crude steel from iron ores using the so-called direct reduced iron (DRI) process (secondary route). The starting point for the efforts to find an alternative to the blast furnace process was the relatively high process expenditure.Read more +

Oct 01, 2018· As theiron oregrade declines, the rate of increase in GHG emissions from mining accelerates. For example, wheniron oregrade decreases from 40% to 35%, the average GHG emissions for mining increases by 12 kg CO 2 e/tonne. In contrast, the same 5%iron oregrade decrease from 20% to 15% would lead to 52 kg CO 2 e/tonne. Thus, China will face ...Read more +
