Splitting machine for open pit mining
hydraulic splitters, also known as hydraulic splitters and hydraulic rock splitters, are composed of power stations and splitters
at present, if explosives can not be used, the hydraulic splitting machine is the best choice
I bought Jiangxi Kaiao's procts at that time, and I feel it's good for personal use.
60MPa pressure oil is supplied to the splitting gun by the hydraulic station. The splitting gun can generate dozens of tons of F thrust to push the wedge piece to expand to both sides, and the expansion force P can reach hundreds of tons, so that the object splits from the inside and separates. We take the granite mining as an example to describe the use process of the splitting machine
first of all, let's look at the process of explosive blasting mining:
drill a hole every 0.5m on the rock surface to be mined, and then put explosive blasting to separate the rock from the mountain
it is necessary to drill holes in the vertical and horizontal directions of the rock. For example, when mining a stone with a length of 10m, a width of 6m and a height of 6m, it is necessary to drill ￠ 40 holes with a total length of more than 310m. After explosive blasting, the stone is often broken into many pieces, so that the utilization rate of stone is less than 30%. That is to say, it is labor-consuming and time-consuming to mine stone by explosive blasting, which also causes a great waste of resources
if the splitting machine is used for mining, just open a few holes and grooves on the stone surface to be mined, and then use the splitting machine to split the stone. In the same way, only 10 holes need to be drilled for the stone with a length of 10 meters, a width of 6 meters and a height of 6 meters, with a total length of 60 meters. Then use a saw to cut a groove 150 mm deep and 5 mm wide between the two holes, with a cumulative length of about 25 meters (Note: it's OK not to cut a groove, but the flatness of the splitting surface is not as good as that of the grooved one). And then the splitting gun is inserted into the hole to split the stone. The stone material split from the mountain by the cleaver is a whole, and the flatness error is generally within a few centimeters. Compared with explosive blasting mining method, splitting machine mining is obviously an economical and efficient method< The characteristics of the splitting machine are as follows:
1. Safety
the controllable operation of the splitting machine in the static hydraulic environment will not proce some hidden dangers like the blasting machine and other percussive demolition and rock drilling equipment; There is no need to take complicated safety measures
2. Environmental protection
when the splitter works, it will not proce vibration, impact, noise, st, flying debris, etc. The surrounding environment will not be affected, even in densely populated areas or indoor, and next to precision equipment, can work without interference
3. Economy
the splitting machine can complete the splitting process in a few seconds, and can work continuously without interruption, with high efficiency, low operation and maintenance cost, and no need to take isolation or other time-consuming and expensive measures like blasting operation
4. Accuracy
different from most removal methods and equipment, the splitter can accurately determine the splitting direction, splitting shape and the size of the required part in advance, with high splitting accuracy
5. Applicability
the user-friendly appearance design and rability structure design of the splitter ensure that its use method is simple and easy to learn, only need single person operation, convenient maintenance and long service life; It is very convenient to transport the splitter and hydraulic pump station
Splitting machine, also known as splitting machine, is a kind of machine used to split materials, which is mostly used in construction, decoration, engineering construction and ore mining
in addition, the models of Kaiao splitting machine are various, so it is recommended to take a look at their real videos to learn about their effects.

Splitting machine | the structure of splitting machine is mainly composed of hydraulic station, oil pipeline, splitting gun, wedge, etc. According to the type of power station can be divided into: electric, diesel, gasoline, pneumatic motor four. According to the material of splitting gun, it can be divided into steel splitting gun and aluminum alloy splitting gun. It can also be classified according to the strength of the split gun
the main functions of hydraulic splitting machine are as follows: Quarrying block materials; 1、 Second disintegration of bulk ore (metallic ore, nonmetallic ore); 2、 Demolition of concrete components (cement pavement, machine tool foundation, bridge and house components), demolition of concrete structures in indoor or narrow space, excavation of tunnels, ditches and other rocks, etc.
