When a device is gradually recognized and affirmed by users, we think that this device is already a mature device, as long as we gather information collected from users and then change it. But for ultra fine mill , this is not the case. On the contrary, due to users' too much expectation and expectation, its improvement is also large and continuous. The amount of technology it contains is more and more, and sometimes it can even represent the technical level of a mill manufacturer to produce grinding equipment.

Speaking of ultra-fine grinding upgrades and improvements, we do not have a talk in which improvements have been made, some justified. But many grinding equipment manufacturers see different needs, and there will be a lot of preferences in the improvement. For example, some from production capacity, powder selection system or wind delivery system, etc. Of course, for most manufacturers, in the equipment improvement, will conduct a comprehensive consideration, but their production equipment itself has the advantages and characteristics of all kinds, according to the milling industry is different, so if we want to talk about the improvement of concrete surface, need to choose a manufacturer, in detail.

First of all, we are introduced from an important classifier. The classification system used for ultra-fine grinding equipment has been adopted by air classifier. When the material is lapped into the classifier, the coarse and fine powder is separated under the action of the graded vortex force. Under the action of the wind, fine powder which meets the requirements of the fineness will be blown into the fine powder collection system. In the classifier, the main one is the blade of the impeller classifier. With the gradual improvement of the production capacity of the plant, the diameter of the blade will also increase, but the wind can not be evenly distributed. Therefore, we need to make many improvements in the structure and process design of the classifier, such as increasing the number of blades of the impeller. Secondly, the air supply system of ultrafine grinding is improved. The wind transmission system is very important, whether it is well matched with the structural parameters, and directly determines whether the classifier can realize the classification function accurately. After that, the feeding control system and the powder system need to be improved.

Well, the last two improvements will be explained in detail. This article aims to introduce the upgrading process of ultrafine grinding in recent years, rather than focusing on the detailed improvement process. And these improvements are all very complex. Designers and producers spend a lot of manpower and material resources to carry out continuous experiments and experiments, and get many valuable guidance from operators and senior mill experts. It can be said that it is the crystallization of many painstaking efforts. Of course, there is a long way to go, whether it is ultrafine grinding or other flour mills. Only in the process of using, is there any possibility of improvement so that we can go on the right and healthy development road.
