Energy efficiency and ecobalance Saving energy and raw materials and increasing sustainability: new approaches in cement production Alongside the high requirements for quality, the construction industry cannot avoid issues such as "energy efficiency" and "ecobalance".
It makes a great building material for miniaturists, but it isn't the same as the more commonly available foam core board. You are best using fine tooth power tools to cut it, but its lightweight, smooth, waterresistant surface makes it ideal for many miniature applications. This material does give off gasses, so it may not be accepted by museums.

Mercury emissions are typically higher in kiln operations with the raw milloff ("direct" operation) due to the missing adsorption capacity of the freshly ground particles in the raw mill. Periodic purging (bleeding) of cement kiln dust from the system is an efficient way to control and reduce mercury emissions.
The Electric arc furnace process, or minimill, does not involve ironmaking. It reuses existing steel, avoiding the need for raw materials and their processing. The furnace is charged with steel scrap, it can also include some direct reduced iron (DRI) or pig iron for chemical balance.
Cement Ball Mill. The ball mill for clinker is an efficient tool for fine powder grinding. It is mainly used to grind the clinker and raw materials in cement industry and also can be applied in metallurgy, chemical, electric power and other industries to grind all kinds of ores.
