Performance comparison: Screen type project, cage drum screen, plane vibrating screen, cantilever vibrating screen, Drum Screen coal type adaptability, adapt to all kinds of coal clocks, only suitable for certain moisture and no impurities, Drum Screen only suitable for certain moisture and no impurities Coal bell. The coal inlet method is flexible and diverse, Drum Screen and can be designed according to the actual situation. It only adapts to belts and hoppers. The size of the coal inlet is fixed, only suitable for belts and hoppers, Drum Screen and the coal inlet size is fixed. The screening efficiency is as high as 95% and 10%-70. %, 10%-80%, depending on the moisture of the coal, Drum Screen and depending on the moisture of the coal.
The sieve content reaches 100% MCR, without restriction (10%-80%) MCR, depending on the coal moisture condition (10%-80%) MCR, depending on the coal moisture condition. The blanking particle size is 6-30mm, which can be adjusted arbitrarily. Due to the fixed screen, Drum Screen the blanking particle size cannot be adjusted arbitrarily and there is an over-standard phenomenon. Large-scale design is flexible, Drum Screen the size limit is smaller than other screen types, easy to large-scale. Large-scale is limited by size, screening efficiency, Drum Screen etc. Large-scale is limited by size, screening efficiency and cantilever material.
Energy consumption is small, which is 50% larger than other screen types. With sealed isolation cover, low noise, good working environment (with sealed isolation cover, Drum Screen no coal dust and coal splash phenomenon) Poor (no sealed isolation cover, coal dust and coal splash phenomenon) Poor (no sealed isolation cover, Drum Screen There are pulverized coal dust and coal splash phenomenon).
Low labor intensity (no need for regular cleaning and cleaning of the area coal) Large (long equipment operation time, regular cleaning and cleaning of the area coal) Large (long equipment operation time, Drum Screen regular cleaning and cleaning of the area coal), The amount of repair and maintenance of wearing parts is small, Drum Screen and the wearing parts only need to replace the bearing. The repair volume is large and there are many wearing parts. The screen and the vibrating motor must be replaced in a short period of time, Drum Screen with a large amount of maintenance and many vulnerable parts. The screen bar and the vibrating motor must be replaced in a short period of time. The guaranteed value of the coal on the boiler is 100%. It cannot be fully guaranteed.
