Advantages of roller distributorsEdit Broadcast The disadvantages of the above-mentioned pendulum-type distributor can be eliminated by using the roller-type distributor for distribution. Roller distributor is the equipment used in metallurgical sintering plants and pelletizing plants. It is characterized by rolling and beating on the rolling rollers, and the material flow is loose and uniform. During the rolling process, the raw balls play the role of re-granulation, so that the raw balls are compacted again, and the internal moisture penetrates into the surface after compaction. That is to say, the formation of water surface is helpful to the improvement of the air permeability of the material layer, and the quality of the green ball is further improved, which provides favorable conditions for the drying operation to achieve high quality and high yield [1] . Editing of technical specifications for roller spreaders The roller distributor is composed of parallel rollers, which are driven by staggered fixed gears. The driving direction of the rollers is the same and is driven by two sets of driving devices. The technical specifications are: L×W 2420×2150mm Roller diameter 108mm Number of rollers 22 groups Roller gap 2mm Roller speed 118 rpm Installation inclination 3° Production capacity 140 tons Motor power 2 x 5.5 watts The greater the number of rollers, the better the uniformity of the cloth and the better the regranulation of the green pellets. According to the specific situation, the number of rollers should be more than 16 groups. Using the roller distributor, due to the improved air permeability of the material layer, the thickness of the material layer is increased from 150-180 mm to 220-240 mm, the production capacity is increased by 25%-30%, and the quality of pellets is also improved accordingly.
