Roller Crusher Roller Crusher is widely used for fine or superfine crushing in the industries of mining, construction materials, metallurgy, chemical industries and so on. . It can crush all kinds of materials under middle hardness, such as ore, rock, coke, coal, clinker, ceramic raw materials, slag, refractory materials, chemical materials and so
The environmental impact of concrete, its manufacture and applications, are complex.Some effects are harmful; others welcome. Many depend on circumstances. A major component of concrete is cement, which has its own environmental and social impacts and contributes largely to those of concrete.
Cement specifications clearly needed a way of prescribing the fineness of cement, and the sieve method was written into standards in the absence of any more useful measure, despite the fact that it provided little guidance as to the likely quality of the cement, particularly as the number of different grinding technologies multiplied.
Jenike & Johanson can help you meet your cement industry needs with retrofitting of bins to alleviate costly material flow problems, implementing new mass flow silos or stockpiles to maximize efficient gravity reclaim, or feeding of alternative fuels to the cement kiln or pre-heater calcination tower.
