With the wide application of crushing machine in different industry, the development of its technology has been under the spotlight. The further development of the market has required the improvement of crushing technology. Here we mainly introduce ultrafine mill. What kind of equipments the ultrafine mill includes? How the ultrafine mill will develop in the future? And what is the market situation in the Indian ultrafine mill market? Let us get some answers by reading the following article.
Ultrafine mill can be classified into three types. First: fluid-energy mill, also known as supersonic speed jet cycling mill. This mill uses compressed air or the high speed airflow generated when the hot steam is ejected from the nozzle to drive the powder into motion. The powder can be grinded as a result of the collision among the powder and the friction with the shell. Finally, the qualified powder will be brought out of the mill with the help of the airflow’s classification. Generally speaking, the size of the final powder will be less than 1μm. Second: vibromill. A spherical eccentric rotor is set in the cylinder, which is driven by the motor for high-speed rotation. The cylinder will be in a high-frequency vibration on both the vertical and horizontal directions owing to the inertial centrifugal force.
The raw material can be processed into powder with the help of the impact force and grinding. If the grinding media is replaced by a cylinder instead of a sphere, the productivity can be enhanced because the grinding media contacts will be from point to line. Third,colloid mill. A disc is rotating at a high speed in the mill and the gap with the fixed disc is adjustable, typically is 0.3mm. The suspension mixed with the powder is added to the mill, and it flows continuously through the aperture between the rotated and fixed disc. Finally the powder can be grinded into less than 1μm. These three classifications can almost cater to the ultrafine needs. However, the continuous change of the market has demanded much more for the ultrafine mill. Whether the development of ultrafine mill can meet the demand of the market or not? And how the ultrafine mill will develop in the future? Where is the ultrafine mill manufactured?
The ultrafine mill covers lots of technology, and its improvement is closely related with other technology, hence, several aspects of the technology are supposed to pay special attention to. First of all, the development of the fine classification equipment matched with ultrafine mill and other associated equipments. The closed-circuit technology which ultrafine grinding technology combines with the classification equipment, can increase productivity and reduce energy consumption, and ensure qualified products granularity.
Second, the key point of the ultrafine technology is the equipment, so it is necessary to improve the quality and performance of the ultrafine machine, so is the development of the ultrafine mill and its classification equipment. Grinding aid and surfactant will be both applied into the ultrafine process. The integration of research and development of equipment and technology will also be ensured. Ultra-fine grinding and classification equipment must be adapted to the specific material characteristics and product specifications. At the same time multi-functional ultra-fine grinding and surface modification equipment should be developed as well, for example, the combination of the ultra-fine grinding and the drying processes, as well as the ultra-fine grinding and surface modification. Last but not least, the development of technology-related research and superfine particle detection and control technology is essential and superfine particle detection and control technology is really important to achieve continuous ultra-fine powder industrialization production.
As for the manufacturer of ultrafine mill, lots of manufacturers spread all over the world, especially for the developed countries. In general, ultrafine mill technology is becoming more mature, and market environment is getting much more stable.
