Mechanized sawing mining of hard rock stone has a history of more than 100 years. So far, it has developed into a series of mature, complete, efficient, advanced and low-cost mining systems.

sawing method is the basic method for mining hard rock. It is suitable for mining of steep ore body, horizontal or small dip ore body.

1.Safety
PLC program + frequency converter dual protection, stop immediately in abnormal conditions such as blade jamming or blade nipping.
2.Efficiency
● Three inverters communicating, automatically control the walking speed, accelerate in case of "soft" and decelerate in case of "hard" to improve cutting efficiency.
● The main motor is controlled by frequency conversion, and the large and small saw blades can be adjusted to a more reasonable cutting line speed according to the type of stone and the cutter to improve the cutting efficiency.
● Using high-efficiency permanent magnet technology, high efficiency and energy saving.
3.Stability
● The mechanical structure adopts finite element analysis. After years of quarrying practice, the structure is stable and reliable.
● Electrical components are customized according to harsh working conditions such as excessive dust in the quarry and unstable voltage. The parts with high failure rate use Siemens and other famous brands.
