Abstract: Aiming at the Pucheng chemical coal handling system in the original design of the two systems is not flexible enough, broken station without bypass system, single engineering more, there are disadvantages of the fork chute and dust system is more backward and other issues, Detailed design of which were analyzed and optimized, Optimized after the two-way system more flexible; broken station to increase the bypass system, the system more energy efficient and reliable; the use of joint construction, to meet the use of functional and investment province; sub-chute at the gate instead of the flap, to avoid the leakage material, ; Dust removal system using dry mist dust instead of bag dust, dust removal effect is more significant. Production practice shows that: the above optimization of chemical coal handling system is reasonable and feasible, it is worth learning from.
