Recycling sorting system allair®

opticalautomaticprocess

The allair® air jig has been developed for the dry sorting of coal. This combines the benefits of sorting via pulsing with the benefits of dry processing – meaning that there is no need to treat the washing water or to dewater the products, for example. Today, the patented allair® system is additionally used in the processing of secondary materials such as slag and construction waste. Improved and consistent product quality through online density monitoring Straight forward operation No need to handle or dispose of slurry Low space requirement as no process water is needed Reduced ash levels without any increase in water content Process does not promote oxidation when separating metals from slag Dry sorting performed with the allair® air jig increases the calorific value of the coal while achieving a significant reduction in the ash and sulphur content. The investment and operating costs are significantly lower than with wet processing as there is zero handling of water. As the allair® air jig successfully separates materials such as pyrite from the raw coal, it helps cut the SO2 emissions generated through the burning of coal. The amount of maintenance and cleaning work required in the power plant is also reduced. Coal consumers can rely on the allair® air jig to reduce their repair workload and increase the calorific value of the coal they use.
