Expansion agent
Expansion agent is a chemical additive that is added to cement. When the cement solidifies and hardens, it The volume expands to split the rock.
Advantages Low unit price, low initial investment cost
Disadvantages
Slow efficiency due to limited splitting force, so when used on hard rock, the holes are very dense and the hardening time is long. Take granite as an example. Hole diameter~drilling spacing~rock splitting time~hours
The mining cost is high. Taking granite as an example, the expansion agent is consumed, the market price is RMB/ton, and the direct consumption of expansion agent alone is up to RMB/ton, plus Drilling labor and other costs, so the mining cost is expected to exceed ~ yuan
Affected by the environment The use of large products is affected by temperature and weather. If the temperature is too high, spray holes will appear, and artificial insulation is required at low temperatures.
Two small hydraulic splitting machines
Advantages small size, low price
Disadvantages
Slow efficiency due to low splitting force, the maximum splitting force is less than 1000 tons, suitable for rock mining with Mohs hardness above It doesn't work. Therefore
It is mainly used in the secondary splitting of isolated rocks
It needs its own hydraulic pump station and an external power supply as the starting force. It is inconvenient to operate when one machine has multiple guns.
The core advantages of super large splitter products
Huge destructive power of more than 1 ton. The destructive power of more than 1 ton is a real figure currently on the market and obtained from pressure test and practical data. The huge destructive power can ensure the splitting effect and ensure the completion quality of the construction period! (The greater the splitting force, the greater the distance between drilling holes, the corresponding time required will be reduced, and the efficiency will be correspondingly increased)
Advantages of technical skills Splitting more than 1 ton The cracking force only requires the pressure provided by the excavator to achieve this indicator. This is a cutting-edge core technology that cannot be compared among current peer technologies. This is thanks to its cutting-edge hydraulic technology and special stress structure design. Compared with the current domestic technology of increasing the splitting force by increasing external oil pressure, it causes huge losses to the hydraulic system of the excavator and the internal cylinder of the splitter, seriously affecting the service life of the splitter and excavator.
Dongguan Juqiang's ultra-large splitting machine is manufactured using the latest steel-making technology. Even in the face of huge forces, it will not break easily, minimizing user losses.
