根据影响滚筒截割能力的因素，提出了在一定功率条件下，采用低转速和少截齿是增强滚筒截割能力的有效途径，并从保证装煤和降低比能耗的观点出发，分析了滚筒转速和截齿总数的合理取植范围。
According to the factors which affect the cutting ability of the drum, it is proposed that using low speed and fewer picks is an effective way to enhance the cutting ability of the drum under a certain power condition. From the perspective of ensuring coal loading and reducing specific energy consumption, Roller speed and the total number of picks a reasonable range of planting.
