Due to the widespread use of the mill in various industries, the development of the mill has also received much attention from various industries. With the development of the market, the ticket mill still needs further improvement. Here we mainly focus on the ultrafine mill. So what are the requirements of ultrafine grinding equipment? What is the future development direction of ultrafine grinding equipment? What is the market for ultrafine grinding equipment? With that in mind, let's read the following passage.
There are three main types of ultrafine grinding equipment. The front class is: flow energy mill, also known as supersonic internal circulation air mill. It uses compressed air or the high-speed air flow generated when hot steam is ejected from the nozzle to drive the powder movement. The powder particles are finely ground by collision with each other and friction with the wall. Finally, the qualified fine powder is brought out of the mill by the classifying effect of the air flow. The particle size of the products is mostly below 1um. The second category is: vibration mill. There is a spherical eccentric rotor in the cylinder, which is directly driven by the motor for high-speed rotation. The inertial centrifugal force makes the cylinder vibrate at high frequency in both vertical and horizontal directions. The powder placed between the grinding bodies in the cylinder is ground fine under the high-frequency impact and grinding action of the grinding bodies. If the cylinder is used instead of the ball as the grinding body, the point contact between the grinding bodies is changed to line contact, which can improve the production capacity. The third type is: colloid mill. There is a high-speed rotating disc in the mill, and the gap between it and the fixed disc is adjustable, usually 0.3mm. The powder is made into a suspension and added to the machine, which flows continuously in the gap between the turntable and the fixed plate, and the powder particles break under the action of high shear speed, forming particles below 1um. These three categories can meet almost any ultrafine grinding needs. But with the constant changes in the development of the market, some higher requirements have emerged. Whether the development of ultrafine grinding equipment can catch up with the market demand? Where is the future development direction of ultrafine grinding equipment? Where is the superfine mill produced?
Ultrafine grinding technology is the synthesis of many technologies, and its development also depends on the progress of related technologies, so the development of ultrafine grinding equipment technology should be concentrated in several aspects. The first is: the development of fine grading equipment and other supporting equipment ultrafine grinding equipment combined with the closed-circuit process of ultrafine grinding and grading equipment, can improve production efficiency, reduce energy consumption, and ensure qualified product particle size. The second is: the key to ultrafine grinding technology is the equipment, so it is necessary to continuously improve and improve the ultrafine grinding equipment. It is necessary to develop a new type of ultrafine grinding equipment and its corresponding classification equipment. Grinding aid and surface active dispersant will be applied in the ultrafine grinding process. Then it is necessary to ensure the integration of equipment and process research and development. Ultrafine grinding and grading equipment must be adapted to specific material characteristics and product indicators. At the same time, it is necessary to develop multi-functional ultrafine grinding and surface modification equipment. For example, the combination of ultrafine grinding and thousands of dry MATS, ultrafine grinding and surface modification. Finally, attention should be paid to the development of particle size detection and control technology related to ultrafine grinding technology. The particle size detection and control technology of ultrafine grinding is one of the important conditions to realize the industrial continuous production of ultrafine powder.
