The advantages of ultrafine crusher from the purpose of crushing

Low-temperature crusher Ultra-low-temperature crusher Automatic feeding machine

Under the action of external force, the solid material overcomes the cohesion of the material, and the process of breaking large particles into small particles is called crushing. Material crushing is accomplished by crushers and pulverizers. The purpose of crushing is as follows.

1. Homogenization As the comminution progresses, the total surface area of ​​the material continues to increase. Therefore, the large-granular material is broken into a fine powder state, so that the mixing of several different solid materials (mainly different in chemical composition) may be achieved and a good uniform effect may be obtained.

2. Mineral processing (dissociation) With the development and utilization of mineral resources, the original ore grade is decreasing, and in order to obtain the active ingredients in the ore, a large amount of ore must be processed after beneficiation. In addition, the number of refractory ores selected in the ore is increasing, and the useful components of the ore are closely associated with the impurities. In order to effectively decompose the ore, only the smashing of the ore is sufficient. After the beneficiation, the useful components can be separated from the impurities. Remove impurities and get a purer concentrate.

Due to the development of industry, more and more elements are required for comprehensive recovery of ore, and the crushing requirements for ore are also more specific, and the requirements for crushing machinery are also higher.

3. Particle size classification In industrial production, due to the specific production process requirements, there are more stringent particle size requirements for solid materials, and the crushing machinery must satisfy the particle size of its products. In the metallurgical industry, its different smelting methods also have different particle size requirements for ore.

4. The specific surface area of ​​the material is increased. The specific surface area is the surface area of ​​the mass or volume of the material. The smaller the particle size of the material is, the larger the specific surface area is. Increasing the specific surface area of ​​the material can increase the contact area of ​​the material with the surrounding medium, and thus the reaction speed can be increased. For example, the contact reaction of the catalyst, the combustion and gasification of the solid fuel, the dissolution, adsorption and drying of the material, and the large contact area of ​​the fluidized bed of powder particles in the chemical industry are used to enhance mass transfer and heat transfer. In addition, in the cement industry, the final product, cement clinker, is ground together with gypsum and the finer the particle size, the larger the specific surface area and the higher the cement number.

5. Ultra-fine crushing With the development of modern industry and the development of new materials, it is necessary to grind the material very finely (10 μm, below). To meet the needs of emerging industries such as fine ceramics, electronic materials, magnetic materials, and catalysts. The current ultrafine crushers include high-speed impact crushers, jet mills, vibratory mills, etc. In order to achieve product granularity, some mills (eg vibratory mills) are designed as closed-circuit systems. After ultrafine particles are resurfaced, the original properties of the particles are changed to suit the process requirements, such as enamel powder for electrostatic spraying.

The above is a summary of the purpose of smashing. From the above description, smashing the material into fine particles to increase its surface area is an important objective of smashing. In recent years, ultrafine smashing technology has been developed. The advantages are even more obvious! Jiangyin Jindun ultra-low-temperature crusher has been committed to the development of ultra-fine crusher technology. We have introduced technology from Germany and Japan, absorbed and digested and developed advanced automatic ultra-fine pulverizer production technology. After years of research, we finally developed the DW-450. The new generation of automatic ultra-low temperature pulverizer, the machine is excellent in the world, unique in China, has made great contributions to the Chinese medicine extraction industry, and also provides economically applicable products and new development opportunities for the development of China's Chinese medicine industry.

The main advantages of this machine are: 1. It is fast and can be crushed at low temperature. Ultrafine grinding technology adopts normal temperature mechanical and mechanical grinding, supersonic airflow pulverization, cold slurry crushing, etc. It will not produce local overheating phenomenon in the crushing process. The pulverizer can even be carried out at a low temperature, and the pulverization can be completed instantaneously, so that the bioactive components of the powder can be retained to a large extent, and the desired high quality product can be produced. 2. The particle size is fine, and the distribution is even. The distribution of external force on the raw material by ultrafine grinding is very uniform. The setting of the grading system not only severely restricts large particles, but also avoids excessive fragmentation. The ultra-fine powder with uniform particle size distribution is obtained, and the specific surface area of ​​the fine powder is increased to a large extent, so that the adsorption and solubility are increased correspondingly. Big. 3, to save raw materials, improve utilization, ultrafine powder can be directly used in the production of preparations after ultrafine pulverization of objects; and the products obtained by conventional pulverization methods still require some intermediate links to achieve direct production requirements. It is likely to cause waste of raw materials. Therefore, this technology is particularly suitable for the smashing of precious materials (such as Ganoderma lucidum spore powder), and also suitable for the ultrafine grinding of traditional Chinese medicines4, reducing pollution, ultrafine grinding is carried out in a closed system, which not only avoids the micropowders polluting the surrounding environment, but also Prevent dust in the air from contaminating the product. Use of this technology in food and healthcare products can control the contamination of microorganisms and dust. 5. The speed of chemical reaction in fermentation and enzymolysis process is greatly increased due to the ultrafine pulverized raw materials. During biological and chemical reactions, the area of ​​reaction contact is greatly increased, and thus the reaction can be improved. Speed ​​saves time in production and improves efficiency. 6, help the body's absorption of food nutrients, studies have shown that, after ultra-micro-pulverized food, due to its very small particle size, nutrients can be released without going a long way, and because of the small powder and more easily adsorbed In the inner wall of the small intestine, this also accelerates the release rate of nutrients so that the food can be absorbed in the small intestine for a sufficient period of time.
