Silo is an important facility in the raw fuel coal storage and transportation system.From the perspectives of process layout,equipment selec-tion,material volume calculation and explosion-proof device of circular coal storage silo,key considerations of silo process design are presented,the con-struction type and working principle of its feeding and discharging equipment are examined,and the material volumes under different feeding and dischar-ging means are compared and calculated,so as to provide a basis for the design of silo feeding and discharging means.
