Slotable split method—the best method for stone mining

1. Grooving tool

In rock drilling holes, if you can drill holes with symmetrical grooves and parallel holes, just like scribing a line on glass with diamonds, stress concentration will occur and the rock will be split in a predetermined direction. By reducing the number of drilling holes, stone blocks with no cracks, no internal injuries and ideal specifications can be mined. The company's patented product (patent number: 93210785) notching tool has the above-mentioned effects.

Composition:
It consists of two parts: the groove cutter (long) and the groove guide cutter (short).

Principle:
Principle of stress concentration: The rock has high compressive strength and low tensile strength. Make full use of the disparity between the two to make the rock in a state of tension and achieve the purpose of separation.

Features:
The grooving tool is equivalent to two special drill rods. The operation is convenient, quick and easy to use. When using it, drill the hole first. After drilling the hole, remove the drill pipe and replace the groove cutter in the grooving tool. Wire positioning, after positioning, replace the groove cutter in the groove tool. The groove speed is very fast, 15-20 times the drilling speed. And there will be no jamming, tool damage, groove cutter angle too blunt to be sharp, spiral groove, etc. The service life of the slot knife is also long. Generally, a slot knife can be carved more than 300 meters on granite and 2000 meters or more on marble. The groove depth can reach more than 6 meters. After the groove is carved, it is effective with hydraulic splitter, static expansion agent and gunpowder shelling, and the dosage is reduced by 1/3 compared with that before the groove is not carved. The granite hole spacing can be released by 2 to 4 times. The marble hole spacing It can be released up to 1.5 to 2 times, thereby greatly reducing the cost of drug delivery and the number of holes.

Two, hydraulic splitting machine

It consists of two parts: splitting machine and power oil station. The huge thrust generated by the oil cylinder driven by the high-pressure oil output by the power oil station, and after being mechanically amplified, can cause the split object to split in a predetermined direction.

Principle:
using the characteristics of rock’s high compressive strength and low tensile strength, using the principle of artificial oblique bond to achieve the effect of splitting the rock by using hydraulic high pressure oil as the energy source

Features: 1. Safety and environmental protection. The hydraulic splitting machine is a controllable work in a static hydraulic environment. It splits quickly and the oil pressure is adjustable. Its power is only 1.5 kilowatts, but the splitting force of a single machine can reach 400-500T. One machine can carry multiple guns; Vibration, impact, noise, dust, flying debris, etc. will be generated, and the surrounding environment will not be affected. Even in densely populated areas or indoors, and near precision equipment, it can work without interference. 2. Economy and use. The hydraulic splitting machine can complete the splitting process in a few seconds, and can work continuously without interruption, with high efficiency; its operation and maintenance costs are very low, without isolation, time-consuming and expensive safety measures, and long service life; ingenious and durable The flexible structure design ensures that its use is simple and easy to learn, and only requires one person to operate; the splitter and the power oil station have the characteristics of small size, light weight, and convenient transportation. 3. Precise and flexible. The hydraulic splitting machine can accurately determine the splitting direction, the split shape and the size of the part to be taken out in advance, with high splitting and dismantling accuracy.
