Rotary drum drier for beneficiation Appliction ofBeneficiation drier This machine is widely used in mine ,building material ,chemical ,metallurgy ,cast industries and so on.It can dry material such as sand ,slag,clay,fly ash ,coal ,iron powder,quartz sand ,ore and so on . Feature ofBeneficiation drier: 1.High efficiency and less energy consumption 2.The efficiency of self heat preservation is higher than 80% ,for single cylinder type ,it is 35%. 3.Compared with the single cylinder type with same capcity ,the 3 cylinder type only cover the 50% ground.It will save the 50% of building cost,60% power cost ,and above 60% fuel. 4.The fuel can be coal ,oil and gas. 5.With the heat resisting ,hear wearing alloy steel plates,Its life is 4 times as the common steel plates. 6.The water content of the product is less than 0.5% after drying . 7.The temperature of out material is lower than 60, it can keep producing and packing without stop . 8.Without the big and small gears,it work with riding wheel. 9.The temperature of out air is low ,and it will increase the life of the life of dust catching system. 10.Simple operation .It is easy to adjust the date of the water content of the product.
