钢缆皮带机是煤矿提升用的主要设备,而承托钢丝绳的托绳轮轮衬一直是采用聚酰胺材料制造,虽说该(尼龙)材料的各项机械性能还算比较理想,但是由于它的机械强度远远低于制造钢丝绳的60~#钢丝,因此它的使用寿命一般只能达到24个月左右。一条1200米长的钢带机,托绳轮大约有1700个左右,平均每月就要消耗70个左右。大约需要资金5000～
The steel belt conveyor is the main equipment used in coal mine upgrading. The carrier of the rope supporting the steel wire rope has always been made of polyamide material. Although the various mechanical properties of the (nylon) material are fairly satisfactory, Mechanical strength is far below the 60 # steel wire rope manufacturing, so its service life is generally only reached about 24 months. A 1,200 meters long strip machine, care round about 1700, an average of about 70 per month consumption. About 5000 ~ need funds
