我厂通过提高球磨机转速、改革碎矿流程以及合理地调整破碎篩分作业等技术措施,使处理矿量较1957年提高了15％左右。一、提高球磨机转速:将第一段8×3圆锥型球磨机转速由23转/分改为26转/分(相当于临界转速的90％),使球磨机处理矿量提高6％左右,排矿产品中-0.075毫米粒级由0.542吨/米~3时增加为0.751吨/米~3时。二、缩小碎矿最终产品粒度:①合理地调整整碎矿比。考虑到细碎机容易发生事故,主要从粗、中碎方面充分挖掘潛力,以达到粗碎给矿300毫米、破碎最
I plant by raising the speed of the ball mill, the reform of crushing process and the reasonable adjustment of crushing and screening operations and other technical measures to make the handling of ore than in 1957 increased by about 15%. First, to improve the speed of the ball mill: the first paragraph of 8 × 3 conical ball mill speed from 23 rev / min to 26 rev / min (equivalent to 90% of the critical speed), so that the ball mill processing ore increased by about 6% -0.075 mm particle size product from 0.542 tons / m ~ 3 to 0.751 tons / m ~ 3 hours. Second, reduce the size of crushed ore final product: â ’¢ reasonable adjustment of broken ore ratio. Taking into account the fine crusher prone to accidents, mainly from the rough, broken in full exploitation of potential in order to achieve coarse crushing to the mine 300 mm, the most broken
