Q:How to distinguish the quality of limestone
Cement industry: for the production of cement lime raw material quality requirements, is the content of calcium carbonate is greater than 75%, the alumina content is less than 2%. For non crystalline limestone, the grain size is 30~80mm.
Q:How is the limestone formed by the crystal
The effective component of lime is the effective calcium oxide and Magnesium Oxide. The effective calcium oxide content in lime and Magnesium Oxide can be determined directly, can also be through the total content of calcium oxide and carbon dioxide with Magnesium Oxide's reflection, lime and undigested residue content requirements; lime powder with fineness requirements; lime powder and the volume stability, fineness and free water content requirements.The national building materials industry will be divided into three grades: building quicklime, building quicklime powder and building slaked lime powder. But in the transportation sector, JTJ034 - 2000 "highway pavement base construction technical specification" is still in accordance with the original national standard (GB1594 - 79) will be quicklime and slaked lime is divided into three grades.
Q:Vertical lime kiln calcination temperature dropped because of what is the source?
The size is too large, the speed depends on the size of limestone and limestone on the surface of lime contact temperature. However, at a certain temperature, the rate of limestone calcination depends on the particle size of limestone. Size is larger, slower calcination. Because the coefficient of thermal conductivity of lime is less than that of lime, the thickness of lime layer increases gradually. So there is often a large limestone limestone, quicklime is the first reason. Ordinary kiln size should be controlled in 40-80mm kiln as well, the large capacity can be relaxed to 50-150mm, in order to save the cost of limestone can also be specialized with a small stone, Tangshan Kimcheon Metallurgical new energy technology development Co Ltd in the design of gravel lime kiln burning pulverized coal special small diameter lime has also made gratifying achievements.
Q:In addition to a small amount of limestone in the test tube to add the right amount of dilute hydrochloric acid, will produce carbon dioxide
The main component of limestone is calcium carbonate, which is decomposed into calcium oxide and carbon dioxide at a higher temperature.
Q:What are the requirements for producing calcium oxide
Mainly depends on the activity of calcium oxide. Selection of raw materials according to the requirements of the product
Q:Do you need limestone powder for high speed or high grade roads?
A friend to study the concrete into the 250 mesh powder filler, the conclusion is that it is best not to use or less use, the amount of 10%-15 significantly reduced the strength of concrete.High speed on the cement label requirements, more sloppy. I am a limestone mining industry technical personnel, limestone mine gravel can be used in the repair of high-speed road, powder does not recommend the use of a large number of.
Q:Limestone grinding, limestone preparation system with what machine is better, where the manufacturer is better?
You don't know what to the grinding fineness, different equipment to achieve different fineness, from coarse grinding to thousands of mesh, is different grinding principle and method, and also from different manufacturers, you see the specific requirements.
Q:How long does it take for limestone to be decomposed in rotary kiln
The main equipment of lime kiln, gas kiln main auxiliary equipment it is because of its fuel gas burner, the burner is through the combustible gas and the required oxygen (air) are mixed according to the proportion in the burner into the furnace combustion, and air volume of different gas required is different, different type of furnace and different heating methods, it needs the flame types are not the same. Such as premixed, semi mixed type, external mixing type and oxidation and neutral flame, reducing flame and so on. So the burner gas kiln to a certain extent determines the effect of calcined lime kiln. Of course, other ancillary equipment is also very important, such as cap see, similarity is very simple, but to ensure that the distribution of it for the amount of wind in the whole kiln kiln section have a good effect.
Q:How to make paper?
The characteristics of the paper: the production process with high technology (which accounted for 80% of limestone, polyethylene accounted for 20%). The product is waterproof and hard to burn, and environmental protection, the paper is more smooth than traditional. The raw material is more economical than the traditional process and the product sales volume is high. At present, the town is in line with the project's production resources, electricity, land and other conditions.
Q:Limestone ore powder
The production of high-grade paper with coating grade calcium carbonate products. This type of fine, high added value and superfine active calcium carbonate is widely used in papermaking process, after crushing the general size - 2 m = 90% for sizing paper making process; - 2 m diameter greater than or equal to 50% is mainly used to coated paper packing.
