摘要
为解决城郊选煤厂块煤分选系统与主选系统不匹配、块煤破碎效果差、手选岗位工劳动量大的问题,采用正反转带式输送机对块煤分选工艺进行改造,并安装两台2PLF90/120型煤用分级式齿辊破碎机提高块煤破碎效果。块煤分选工艺和破碎设备改进后,该厂块煤分选系统与主选系统完全匹配,块煤破碎效果得到改善,手选岗位工劳动量减少,块煤分选工艺的灵活性提高。
In order to solve the problems of lump coal separation system and main separation system do not match,poor breaking result of lump coal and high labor intensity of hand picking post,the positive and negative rotation belt conveyor is used for reformation of the lump coal separation process,and added two sets of 2PLF90 /120 sizing toothed roll crusher to improve the lump coal breaking effect.After the optimization of lump coal separation process and crushing equipment,the lump coal separation system is fully matched with main election system,the lump coal breaking effect is increased,hand picking post labor amount is reduced,and the washing process flexibility is improved.
