Carbon black is an amorphous carbon. The appearance is a light, loose and extremely fine black powder with a very large surface area. It is a product of carbonaceous materials (coal, natural gas, heavy oil, fuel oil   etc.) which are incompletely burned or decomposed by heat under insufficient air conditions. U se Carbon black is mainly used as a reinforcing agent and filler for rubber, and its consumption is about half of the rubber consumption. The carbon black for rubber accounts for 94% of the total carbon black, of which about 60% is used for tire manufacturing. In addition, carbon black is also used as a colorant for inks, coatings and plastics, as well as an ultraviolet light shielding agent for plastic products. It is also an important adjuvant in many other products such as electrodes, dry batteries, resistors, explosives, cosmetics and polishing pastes. Here, carbon black can be classified into three types according to the use and use characteristics: carbon bla...

Rare earth does not refer to a specific substance, but is a general term for 17 elements of lanthanides and lanthanum and cerium in the chemical periodic table. Currently, there are 250 rare earth minerals in nature. In the industrial field, rare earth elements are known as "industrial vitamins". At the same time, because rare earths have good physical properties such as light electromagnetics, they can be combined with other materials to form new materials with various properties and   varieties, which significantly improve the quality and performance of products. Therefore, there is also the name of "industrial gold". In actual production, rare earth has a large effect and low dosage. It has become an important element to improve product structure, improve scientific and technological content, and promote technological progress in the industry. It has been widely applied to metallurgy, military, petrochemical, glass ceramics, agriculture and new materials ...

1.  T he manufacturing precision of grinding ring Since the grinding ring rotating with the spindle is one of the main wearing parts when the grinding m ill  is working, the manufacturing precision of the grinding ring directly affects the service life of the grinding ring, and the key points are to control the radial runout of the grinding ring and the heat treatment d eformation   of the grinding ring, radial runout and internal diameter deformation will increase the impact on the grinding roller, vibration, and increase the additional load, thus shortening the service life of the grinding roller and the grinding ring. 2. The positive pressure of grinding roller and the gap between grinding roller and grinding rings The positive pressure of the grinding roller is adjusted by an external spring. The appropriate spring pressure must be adjusted according to the hardness, particle size, moisture content, feed size and fineness of the desired product, while ...

As an important energy source, coal is widely used in today's metallurgical and chemical industries and is one of the most important raw materials. Petroleum coke is the waste generated in the process of petroleum refining. With the improvement of the level of science and technology, we can now process the petroleum coke. After grinding to a certain degree of fineness, it is fully burned as a solid fuel, and with high heat and low c ost, environmental protection , which is a  new energy source that meet our ideals. In actual use, coal can be divided into the following types depending on the type, composition, quality, and calorific value :    - lignite, loose texture, low ignition point, volatile matter of about 40%;    - bituminous coal, the texture is tight, the ignition point is not high, and the volatile matter is above 30%;    - Anthracite, with tight texture, high ignition point and volatile content below 10%. Petroleum c...

In the actual production process, the main chemical component  like iron and other impurities   that affects the whiteness of calcium carbonat e . Therefore, most companies pay attention to the strict selection of lime. In addition, in the process, limestone is calcined and digested. The refining process also has an effect on the whiteness of calcium carbonate . 1 Limestone quality In limestone, the main chemical component that affects the whiteness is the content of impurities such as iron, manganese, and hydrochloric acid insolubles. Among them, iron is mainly in the form of ferric ions in calcium carbonate, which is the main cause of the decrease in whiteness of calcium carbonate. Therefore, the whitening of calcium carbonate is the removal of iron by physical and chemical methods. 2 C alcination In the beneficiation stage, the quality of limestone is not up to standard, the impurity content is too high, and harmful impurities such as silica, alumina and ...
