Q:Powdered activated carbon and globular activated carbon which is good: These two kinds of activated carbon can not say who is good or bad, can only say that you are used where, what to do with. Like the powdered activated carbon used in food decolorization, more sugar decolorization field. The spherical activated carbon is used for solvent recovery, air purification up to. These two products have different uses. Corresponding products must be used for different purposes.

Q:The difference between ginger and roasted ginger ginger charcoal.: In the processing practice, etc. in sand with fried for good, hot method has uniform heating, the advantages of uniform processing degree. And the processing time is short, less loss. Ginger charcoal should be a good fried (fried carbon method), easy to deal with. Because the processing degree, ginger carbonization less loss rate is generally 20%, while ginger carbonization, the loss rate is as high as 40%, resulting in higher costs.

Q:Coal can be used to do: 5) living coal: the number of living coal is also large, accounting for about 20%. of fuel coal6 metallurgical power coal: Metallurgical power coal is mainly used for sintering and blast furnace coal injection, the use of less than the amount of coal power 1%.

Q:What is the standard of coal: Characteristics of mineral raw materials(1) physical properties of coalThe physical property of coal is the external manifestation of certain chemical composition and molecular structure of coal. It is determined by the factors such as the original material and its accumulation conditions, the conversion process, the degree of coalification and the degree of wind and oxidation. Including color, gloss, pink, specific gravity and bulk density, hardness, brittleness, fracture and conductivity, etc.. Among them, in addition to the specific gravity and conductivity need to be measured in the laboratory, the other can be determined according to the naked eye observation. The physical properties of coal can be used as the basis for the preliminary evaluation of coal quality, and it is used to study the cause of formation and metamorphism of coal.

Q:What kinds of coal are there? What are their names?: According to the classification of coal China, which accounted for 27.65% of the class of non coking coal, coking coal accounted for 72.35%, including the former coal (13.75%), (3.53%) coal, coking coal, lean coal (5.81%) (4.01%), the other is divided into grades of coal (0.55%); the latter includes smokeless coal (10.93%), coal (5.55%), weakly caking coal (1.74%), (13.8%) non caking coal, long flame coal (12.52%), brown (12.76%), natural coke (0.19%), not the grades of coal (13.80%) and grade (coal is not clear 1.06%). Category: coal is divided into major categories according to the degree of coalification and process performance.

Q:What are the uses of coal?: The use of coal is very extensive, according to the purpose of its use for two main purposes: (1) power coal, (2) coking coal.

Q:What is the use of power coal: The use of power coal as a raw material for power is generally defined as the use of coal for thermal power generation

Q:What is the proportion of dry activated carbon: The other kind of admixture is ash, which is the inorganic part of activated carbon, and ash can easily cause two pollution in activated carbon.

Q:What is the meaning of coal m40.m10: The strength of coke is usually represented by two indices of crushing strength and abrasion resistance. Coke crushing strength refers to coke can resist foreign impact force without ability along cracks or defects at the broken, represented by the M40 value; wear strength of coke coke refers to the ability to resist external friction without surface of glass forming debris or powder, said M10. The cracking degree of coke affects the M40 value of its breaking strength, and the pore structure of coke affects the M10 value. There are many methods for determination of M40 and M10 value method, commonly used in our country the German migon drum test.

Q:What is the difference between coal and coal?: Coal refers to raw coal, excluding coal washing, coal preparation and other coal productsRaw coal refers to the coal that has not been screened, washed, selected, and so on. It needs to be collected from the coal mineCoal washing, coal preparation and other coal products, do not need to levy resource tax
