Guilin Hengda   Raymond Mill  is used in new fields - h igh t itanium s lag  grinding . High titanium slag is a type of titanium slag derived from ilmenite. The ilmenite is mixed with a certain amount of carbon-containing reducing agent and added to an electric furnace for reduction smelting. The iron oxide in the ore is selectively reduced to metallic iron, and the titanium oxide is enriched to form a product, which is titanium slag. Titanium slag with  a titanium dioxide content of more than 90% is usually referred to as high titanium slag. High titanium slag is a kind of titanium ore enrichment or enriched titanium ore. It is a high-quality raw material for producing titanium dioxide. Compared with ilmenite, the ratio of ilmenite is high, and the iron content is low, which not only eliminates the production of ferrous sulfate , t he sulfuric acid consumption is reduced, the iron powder reduction is omitted,  but also the transportation amount of the r...

Ultrafine mill  is a common equipment for producing ultrafine  powder. W hich areas does ultrafine  powder applied  in ? The ultrafine powder material refers to a type of material having a characteristic size of the material component between 0.1 and 100 nm, and the material is composed of a "particle component" and an "interface component". Under the radiation of the microwave field, the atomic electron motion in the ultrafine powder material is intensified, which causes the magnetization to convert the electromagnetic energy into heat energy, thereby increasing the absorption performance of the electromagnetic wave.

The classifier is an important part of   Raymond Mill  and is indispensable for environmentally friendly Raymond mill. The following is an introduction to the Raymond mill environmental protection classifier: The whole grading device is composed of a gas classifier, a cyclone collector, a pulse dust collector, a high pressure induced draft fan, an electric control cabinet and so on . The air classifier is a forced classifier with a large impeller rotor with secondary air inlet and vertical installation. When the Raymond mill is working , the material enters from the lower cylinder under the action of the gravitational pull of the induced draft fan. The primary air is fully mixed with the material, so that the particles are fully dispersed and rise to the classification zone. Due to the high-speed rotation of the graded impeller rotor, the particles are not only influenced by t he centrifugal force generated by the rotation of the graded impeller but also the centri...

The development of architectural coatings in China has a history of nearly forty years. From scratch to product, from low-grade to high-grade, it has gradually become serialized. However, in general, Chin ese  architectural coatings still have a large gap with developed countries. For example, the proportion of high-grade coatings based on synthetic resins such as styrene-acrylic emulsion is small; the production scale is small, the equipment is simple, and the production efficiency is low; Auxiliary, color paste and other related supporting levels are low. Moreover, the current domestic architectural coatings market is mixed with fish and dragons, the quality of latex paints is uneven, and it is difficult to obtain the trust of consumers. As for foreign similar coatings, consumers are discouraged because of their high price. The main reason for the lag in the coating industry is the backwardness of coating additives (powders). Ordinary powders can not meet the requirements...

Ultrafine calcium carbonate powder is widely used in the paper   making industry and plays a n important  role. Ultrafine mill   is  widely used in the processing of calcium carbonate. The original purpose of paper   making and fillering was to reduce the cost of paper. The main purpose now is to give paper some special properties. Due to the different purposes of filling, the proportion of fillers in paper varies greatly, generally between 10% and 20%. The use of a filler or several fillers depends on the particular properties of the paper required. Among all types of paper, printing paper and writing paper have the largest amount of filler. Fillers help to improve the following properties of paper: 1 .  Improve the formation and smoothness of the paper by filling the gaps in the paper sheet; 2 .   I ncrease the opacity and whiteness of the paper; 3 .   I ncrease printability; 4 .   I ncrease dimensional stability; 5 . ...

We are no stranger to graphite, the pencil refill is made of it. Scientists have found a big use for graphite   recentl y, they have made graphite into new electronic components, which ma kes  graphite become a potential new generation of nanoscale electronic components. The use of graphite layer sheets to fabricate carbon nanotubes yields can get all of the properties of nanotubes because these properties are formed by the graphite layer and its constraining of electrons, but not by nanotube structures. The graphite layer carbon nanotubes simply roll the graphite layer into a cylindrical structure. The researchers heated the silicon carbide sheet at a high temperature in a vacuum to allow silicon atoms to escape from the surface, leaving a thin layer of graphite on the surface. They used current circuit printing techniques to engrave the graphite layer into a graphite layer circuit with a line width of 80 nanometers. The circuit exhibits high electron mobility and exhi...

At present, the application of the mill is very extensive. At the beginning, there was a Raymond mill , and the high-pressure mill was developed slowly. It can also be said that the high-pressure mill is a derivative of the Raymond mill. From the appearance, there is no difference between high-pressure grinding and Raymond grinding. The main difference lies in the input  size, output  size  and production . Input  size : Raymond mill: the smaller the feed  is , the more stable the output  is , the higher the processing efficiency  will be High-pressure mill: the feed size is larger than the range of Raymond mill Output  size : Raymond Mill: 80-600 mesh High-pressure mill : 600 - 3000 mesh, the finished product is finer and the sieve rate is higher Production : Raymond Mill:  the production is  lower than high pressure mill High pressure mill: high pressure with high pressure spring, the output is  higher ...
