Air-sweep pulverizer

Overview

Drying and sweeping grinding technology can be simply said that the material is crushed and dried at the same time during the grinding process. Since the material stays in the for a long time and is crushed and dried at the same time, large particles of material are dispersed in the hot air flow, the surface is dried and the particle size is continuously reduced, and small particles and powdery materials: suspended in the hot air flow, directly and fully contact with the hot air flow, large contact area, rapid heat exchange to it instantly dry.
 

At the same time, because of the high wind speed in the mill, the water vapor and fine powder produced during the drying and grinding process can be from the mill in time, which avoids the bad phenomena such as sticking, sticking and blocking, and reduces the chance of over-grinding and the formation of material pads, so grinding efficiency of the mill is very high. With the development of dry production in the cement industry, the technology of raw material drying and sweeping system has become more and more mature valued. On the basis of the original experience, the global heavy industry has invested in the research and production of new raw material drying and sweeping mill technology and equipment according to the grinding of small and medium-sized cement raw material mills. This technology and equipment have been widely used in the technological transformation of raw material mills with moisture content, no dryer or poor drying low production capacity. This product has a large production increase, electricity saving; compared with the use of dryers, it saves coal by forty to seventy percent, which is a for dryers, and the equipment technology is mature and reliable.

Advantages

1. Can be produced continuously, with large production capacity, high grinding efficiency, easy adjustment of fineness, and low energy loss.

2. It can grind and dry coal of various hardness.

3. The feed device of this coal mill adopts a louver-style structure with oblique air and material feed, which enhances the thermal exchange capacity of the coal mill making the feed more smooth and effectively preventing the phenomenon of material blockage at the coal mill inlet.

4. The equipment structure is compact, with few transmission parts, low maintenance costs, stable operation, and easy installation.
