During the underground cutting process, if the Roadheader Picks encounter hard rock formations, especially those rich in quartz, the cutting resistance and strength of the Roadheader Picks will increase, resulting in rapid wear and failure of the teeth, causing a rapid increase in material consumption and downtime during the cutting process, reducing tunneling work efficiency and increasing tunneling costs.
Luoyang XTC established a corresponding mechanical model for the force analysis of the cutting teeth during the tunneling process of the tunneling machine. The results of the full-rock tunnel cutting test proved that the cutting force formula is basically correct. On this basis, the factors affecting the cutting force of the cutter during the tunneling of the full-rock tunnel were analyzed. The tunneling cutter S200-Z40MC1 was developed for underground mining of hard rocks such as quartz . After being tested by many mining companies , it significantly improved the tunneling efficiency, reduced the cutting cost, and extended the service life of the cutter by 20 % -50%, which received unanimous praise from users.
Main advantages of S200-Z40MC1 Roadheader Picks:
1. It adopts XTC's self-developed low-cobalt ultra-coarse grain alloy, and the head adopts XTC's self-developed high-wear-resistant ceramic wear-resistant coating, which has excellent wear resistance and extends service life;
2. The use of 40mm diameter straight alloy and unique cutter head geometry reduces cutting resistance and improves tunneling efficiency ;
3. Large diameter alloy has excellent impact resistance, high hardness, toughness and thermal fatigue resistance, and is suitable for hard rock conditions such as quartz sandstone, basalt, granite and limestone;
This article shares a test of a new Jinlu product at a coal mine in Pingdingshan . The excavation face is 5 meters (width) by 4 meters (height), and the rock strata are layered: tabular limestone at the top and denser limestone containing quartz at the bottom. The equipment is a Shimei 320 longitudinal axis roadheader, equipped with 54 picks, a cutting depth of 1 meter, and 20 picks installed at the front end of the cutting head for testing. XTC's new product consumes 2-3 picks per tool and 4-6 picks per shift. Manufacturer N consumes 20+ picks per shift, while XTC's consumption is lower than that of Manufacturer N. Our customers highly recognize the quality of our Roadheader Picks!
