Ore Mining With Rock Saws Has Become Mainstream

2022-04-25

With the development of society, the market demand for stone is increasing, and the quarrying pressure is also increasing. Most modern quarries use traditional wire saws for ore mining. After cutting with a mountain saw, use manual steel nails to lift the bottom.
This operation has many disadvantages. One is that the mountain saw needs to lay tracks, which is cumbersome to operate, and some quarries have a large slope and cannot be laid. The second is the high cost. The diamond beaded wire saw is a wear part and needs to be replaced every once in a while.

At this time, the excavation and modification of the rock saw shows its unique advantages. The equipment is mostly installed on 20-ton excavators, and it can be cut wherever it goes. For stone blocks, one machine can be used for multiple purposes, vertical cutting, horizontal cutting after rotation, bottoming, cutting, and mechanized construction, which greatly reduces labor costs and saves time and effort.

Taking the Pinglei quarry in Guilin, Guangxi as an example, a Yichen YS-20SS rock saw was installed on a VOLVO270 excavator to cut green rock. The cutting gap of the rock saw is 2 cm. Due to the grinding and cutting, the cutting gap is smooth and neat, which greatly improves the yield and integrity of green rock mining.

At the quarrying site, Yichen's rock saw wears a saw blade with a diameter of 2.6 meters. Under the condition of a cutting depth of 1.1 meters, the cutting depth is 15 meters to 20 meters per hour, and the daily quarrying is about 100 cubic meters.green rock's current price ranges from 800 to 1,200 yuan per cubic meter, with daily sales reaching about 100,000 yuan.
In terms of cost, the rock saw uses the hydraulic power system of the excavator and is installed on the hydraulic oil road of the excavator hammer. The driver only needs the plate pedal, which is half the speed of the hammer, and the oil cost is lower.
