Advantages of Pneumatic Conveying Pulverized Coal Biaxial Humidification Mixer
2020-01-08 Source: wglobalnba.com Author: Rich Machinery read: Times
In the pneumatic conveying pulverized coal system, a dual-shaft humidifying mixer is often used to humidify and stir the pulverized coal, which is convenient for transportation. Then the dual-shaft humidifying mixer has the following advantages compared to the single-shaft mixer:
The double-shaft mixer is driven by a cycloid pinwheel reducer, which rotates smoothly and has low noise. The twin-shaft mixer feeds from the top and discharges from the bottom. The structure is reasonable. The sealing surfaces of the two-shaft mixers are tightly sealed and the operation is stable. The twin-shaft mixer is a self-falling mixer with a humidifying water spray system to ensure uniform water spray and adjust the water supply to meet the needs. The dual-shaft mixer uses a hand pressure oil pump to centrally supply four transmission bearing lubricating greases, which is convenient for the use and maintenance of the equipment, and has the advantages of high efficiency and time saving. SZJ double-shaft mixer adopts two sets of spiral blades for stirring, which has the characteristics of high stirring efficiency, small floor area, spiral blades using high wear-resistant special alloys or composite ceramics, and long service life.
Difference: In terms of manufacturing materials, the baffle of the double-horizontal shaft mixer can be made of relatively inexpensive ordinary steel plates, and the requirements for wear resistance are relatively low. The speed of the single-shaft horizontal mixer's blades in the circular motion is relatively high, and the trajectory of the blades will also be in contact with the rotating shaft during the operation, so the wear of the single-shaft horizontal mixer is obvious. Parts replacement is also more frequent. In terms of manufacturing materials, the single-shaft horizontal mixer needs a baffle made of special steel, so its maintenance cost has also increased accordingly.
