2nd Raymond mill machining Silicon carbide
Silicon carbide is produced at high temperature in an electric resistance type furnace with quartz sand and petroleum coke as its main raw materials. Its hardness is between fused alumina and synthetic diamond. The mechanical intensity of it is higher than that of fused alumina. It is brittle and sharp and has electrical and heat conductivity in some degree. Black silicon carbide is suitable for grinding cast iron, non-ferrous metal, leather, rubber, wood, rock, it also be used as high grade refractory material.
Anthracite carbonizer is an additive for steelmaking. The quality is based on the content of fixed carbon (Fixed Carbon). It is classified into special grade (Fc≥95%), first grade (Fc≥94%), and second grade (Fc≥93%). , three grades (Fc ≥ 90%), in which the fixed carbon content is higher than 95% of the special charcoal, the carbon effect can be comparable with FC: 98% petroleum coke, the price is less than 1/2 of the petroleum coke It is a widely used petroleum coke substitute in the world.
Super Activated Carbon
Activated carbon adsorption desulfurization and denitrification technology can realize the resource utilization of pollution control products. 6mm carbon can remove the SO2 in the flue gas desulfurization (sulfur dioxide), denitrification is mainly from NOx in flue gas (nitrogen oxide), the two substances into the atmosphere will be the formation of acid rain, acid rain harm is very large, so now the country has been promoting environmental protection, thermal power plant are now built simultaneous construction of desulfurization, denitrification and now the state has not started to force. It has the advantages of high desulfurization and denitrification efficiency, and is considered as a promising desulfurization and denitrification technology. In all kinds of smoke The activated carbon adsorption method is the only way to remove every impurity in the flue gas,
Anthracite Filter Media
Raw Material: High quality anthracite produced in Ningxia, China Anthracite filter media is a kind of filter used in water treatment. It can be applied in the treatment of common acid, the middle degree alkali. The product has large surface area, and its various indexes all exceed the Construction Department's standard. Anthracite filter media is especially selected from the deep well minerals, so it contains the highest percentage of carbon.The raw material is always filtered and washed to make sure that the product can have good effect on water filtration.
CAC 92 anthracite based carbon additive made from well-selected Ningxia TaiXi anthracite. Mainly used for steelmaking in electrical, foundry industry to increase the content of carbon.
Silicon Carbide Powder
Silicon carbide powder of SiC 98.0% min ,Fe2O3 is 0.08% max,particle size can pass 100-180mesh sieve . This product also known as silicon carbide sand,generally divided into mesh grade sand from 8#-320#,the greater the number is,the smaller particle size it is. Silicon carbide particle size of sand is dvided into green and black. It is the ideal for abrasive material,mainly used in polishing and grinding wheel,cutting slices,and etc sectors in abrasive industry.
carbon additive 93%
Anthracite filter material with high quality anthracite as raw material, through the selection, crushing, and two screening, high mechanical strength, good compression performance, chemical stability, no toxic substances, wear resistance, in acid, neutral, alkaline water are not dissolved, and anthracite particle surface roughness, good adsorption capacity, high porosity, with light, low required back washing strength, can save a lot of water and electricity.

Anthracite filter material is widely used in water treatment industry. Anthracite filter material is a high quality anthracite as raw material, by crushing, powder, sieve and other processes Anthracite filter material in the process of filtering , directly affect the filtration of water quality, so the choice of the filter material must meet the following requirements: 1. High mechanical strength, crushing rate and wear rate should not be higher than 3% (by weight). 2. Stable chemical properties, without toxic and harmful substances. It is insoluble in ordinary acid, alkaline and neutral water. Our products are determined by China water treatment filter media supervision and testing center: the hydrochloric acid soluble rate is 0.98% (the ministerial standard is 3.5), all kinds of water sources can achieve good purification effect. 3. The particle size distribution is reasonable and the specific surface area is good. The appearance of the product is spherical and angular, glossiness is good, and it is screened by mechanical vibration for three times. The gradation accords with the relevant technical indexes. 4. The particle size range is less than the specified minimum diameter, according to the weight is not greater than 3%, greater than the specified upper limit of particle size, not more than 2% by weight.
