           The Coal Separating Plant of the Indonesian Kalimantan Aulia coal company has the production capacity of 1 million tons per year with the in-washing capacity of 189.39 tons of raw coal each hour,working for 330 days per year ,working for 16 hours each day.

   Output of 5 products:the refined coal,the medium coal,the flotation coal ,gangue and tailings slurry.

   The raw coal adapt the coal pit for receiving the coals , the refined coal products are stored by the tape machines ,the medium coal lands on the ground with a single point for the pile ,the waste rock is put into the storehouse,the flotation tailings coal are concentrated、pressed、filtered and put to the field.

   the refined coal moisture is ≤11%;the medium consumption of the tons of raw coal production is ≤2Kg;the washing water cycle in the closed system.

    The production process :the raw coal in the raw coal storage yard through the coal pit by the conveyor belt is transported to the raw coal preparation plant,firstly being grade screened by the grading screen of 70(50)mm,the +70(50)mm raw coal to be broken by manual selection,and to be mixed with the 70(50)-0mm raw coal under grading sieve ,and then to be transported to the main building for the separation.The 70(50)-0mm raw coal directly transported into the large-diameter non-pressurized feeding heavy medium cyclone for the products separation,with a single low-density flotation liquid for the one-time to sub-elect in the three products such as the refined coal,the medium coal ,and gangue .After the classification of medium dehydration of the refined coal ,the blocks of the refined coal is directly viewed as the ultimate refined coal ,the end refined coal go through the second centrifuge dewatering and viewed as the  ultimate refined coal ,to be transported storehouse;after the dehydration and the classification of medium coal products,the block of the medium coal,directly viewed as the final products,through the second dewatering of coal with the centrifuge as the ultimate medium coal,and then to be transported by belt conveyor to the ground outside the factory;after dehydration the gangue is loaded into the warehouse.

 (Suitable for coal preparation plants with an annual raw coal processing capacity of 600,000 tons)
