Alternative Explosives for Blasting Rock

Shenzhen Yandu Technology is a limited company integrating production and direct sales. The company independently produces hydraulic rock static mining equipment. Master high technology and maintain high-end quality. We are more professional in making liquid rock static mining rock equipment.
The rapid economic development has brought about earth-shaking changes in all walks of life. In the construction of modern cities, great changes have been discovered in just one industry. During the construction process, we often encounter stones. In the past, the best way to mine stone was direct traditional mining. It is fast, but it turns out that traditional methods are dangerous and can easily cause casualties. There is a certain threat to people's lives and property. Nowadays, national control is also very strict, making stone mining much more difficult.
A new era, a new life is active in front of us. That is hydraulic static rock mining equipment, which achieves silent mining, controllable mining and safe mining. It has been widely affirmed and recognized, and has also been widely practiced and credited. Among many hydraulic static rock mining equipment, Yandu hydraulic expansion rod has become a trendsetter in the industry.
Yandu brand hydraulic expansion rod
It is composed of a cylinder, a piston, multiple seals, and multiple high-pressure oil pipes. It is divided into an oil inlet pipe and an oil return pipe. When oil is fed in, the piston of the hydraulic rock breaking rod will extend. This is a working process, which is also the time for the rock to break. Its power source is a hydraulic power station that transmits hydraulic oil through oil pipes, which can achieve a theoretical split power root. A power station can have a maximum distribution root. The standard configuration is root.
Yandu brand hydraulic expansion rod high pressure oil pipe.
Among all hydraulic equipment, the hydraulic oil pipe is the traffic chokepoint for the entire hydraulic system. It is responsible for transmitting hydraulic oil and has extremely high compressive strength requirements. If the quality of the hydraulic oil pipe is not up to standard, pipe explosion accidents may occur, which may cause personal injury to the workers and pose certain safety risks. We should reject inferior hydraulic oil pipes. The high-pressure oil pipes used by Yandu have the highest pressure resistance, while Yandu expansion rods only require. The oil pipe is mainly composed of an inner rubber layer, a middle rubber layer, a steel wire winding layer, and an outer rubber layer. The inner rubber layer has the function of making the conveying medium bear pressure and protecting the steel wire from erosion. The outer rubber layer protects the steel wire from damage. The steel wire (ф reinforcement layer) layer is the skeleton material and plays a reinforcing role. Every high-pressure oil pipe must be inspected before leaving the factory. Only after passing the inspection can it be put into the market. It has a high safety factor and can be used with confidence.
Practical application of Yandu brand hydraulic expansion rod.
Add anti-wear hydraulic oil to the oil station and fill it up. There is a cursor below the hydraulic oil station, just refer to the cursor.
Three-phase and four-wire connections need to be made. The motor needs to be driven forward, clockwise.
Connect the high-pressure oil pipe to the expansion rod. The color of the oil pipe can be divided into blue and black. The blue pipe is high pressure and the black pipe is low pressure.
Drilling machine, hole, the shallowest hole depth is meters. It can be deep but not shallow
The distance between the rods and the free surface is based on the standards for granite mining. Depends on rock quality.
The working of Yandu brand hydraulic expansion rod.
The working time is short, which is the time for the piston to extend from the cylinder. It takes minutes to achieve the obvious effect of splitting rocks. First, put the hydraulic expansion rod into the hole, making sure that the piston is fully inserted. Start the power supply, change the manual reversing valve to the blue oil pipe, start oil inflow, the piston begins to extend, and generate thrust in the direction of the free surface in the hole, and splitting lines will appear on the rock surface. When the hydraulic oil gauge shows that the hydraulic pressure is reached, it means that the work is completed. As long as the black oil pipe of the manual valve is changed, the piston contracts and is manually lifted out. Repeat in sequence, the operation is simple and easy to learn.
Advantages of Yandu brand hydraulic expansion rods
Compared with cement expansion agents, the waiting time for mining rocks is too long, the mining speed of rocks is too slow, and manual drilling requires a lot of work but the square footage cannot be increased. . It cannot be reused. Hydraulic splitting machine is also a high-quality equipment produced by our company. It is only suitable for mining small cubic meters of stone. As for drilling holes, Yandu brand hydraulic splitting machine can only drill small holes with artificial holes. Yandu brand hydraulic expansion rods are machine-drilled and require large holes. Mining rock fast, saving cost, mining rock silently, hydraulic blasting of stone, best equipment.
The main fields of Yandu brand hydraulic expansion rods.
Suitable for silent mining of various hard rocks, granite, volcanic rock, quartzite, basalt, quartz porphyry, siliceous schist, sandstone, limestone, marble, dolomite, pyrite, etc. A large amount of stone is mined silently, the breaker hammer cannot break it, the expansion agent cannot be separated, the splitter speed is slow, and the hydraulic expansion rod is the wisest choice.
Choose Shenzhen Yandu Technology, we will provide the most professional technical guidance and the most complete construction plan. We keep pace with the times, stay at the forefront of technology, and create first-class international quality. Our purpose is, Yandu Technology does not separate rocks, but separates rocks for you. We insist on making the best equipment and separating the hardest rocks
