The main advantages of dry coal preparation:

(1) Only 1/4 to 1/5 investment compared to the washing coal equipment. Dry coal preparation process is simple, due to no water in the process, no coal slime water treatment treatment system, which reduces the investment.

(2) Small maintenance volume, smooth operation, simple operation, low production costs, processing costs only 2 to 4 CNY / T. 

(3) High production efficiency, less production workers needed.

(4) Wide inlet size range. Raw coal below 80mm can be graded, or not graded. 

(5) The moisture requirements of raw coal are not strict, the external moisture need to be less than  9%, and internal moisture is not limited.

(6) The use of wind volume is 1/3 of the traditional wind preparation equipment. 

(7) Small footprint. For simple systems, it directly uses steel structure assembly dry selection system. 

(8) Good dust removal effect. The discharged part of the gas contains dust is 50 mg/m3, which is below the national standard of 150 mg/m3.
