Sand suction machines are mechanical equipment specially used for conveying loose sand in water or on the ground. Due to the small sand particles, good fluidity, and high specific gravity, traditional conveying methods are difficult to achieve continuous and efficient transportation. Sand suction machines can effectively and quickly absorb sand in water or in a wet state and transport it to a designated location through vacuum suction or mechanical screws.
Small-sized sand particles are easier to be sucked out and transported at a fast speed due to their small inertia, while large-sized sand particles may cause pipe blockage due to their low speed; sand particles with higher density require greater negative pressure to be effectively sucked in and transported; sand particles with high water content tend to adhere to the inner wall of the pipe, increasing the transport resistance.
Vehicle-mounted sand suction machine: This type of sand suction machine is usually installed on a vehicle and has high mobility and flexibility. They can be quickly deployed to different work sites and are suitable for scenes that require frequent transfers or operations in multiple locations, such as river dredging, pond cleaning, or small port maintenance.
Hose spiral sand suction machine: This type of sand suction machine mainly relies on a hose and an internal spiral device to absorb and transport sediment. They are usually designed to be lightweight and easy to operate, and can penetrate into narrow or difficult-to-reach areas for operation. Hose spiral sand suction machines are often used for small water body cleaning, sand pit extraction, or applications that require precise control of the amount of suction.
Stainless steel sand suction machine: The main feature of this sand suction machine is that its main body or key components are made of stainless steel. Stainless steel has excellent corrosion resistance, so stainless steel sand suction machine is particularly suitable for handling mud and sand containing corrosive media, or working in corrosive environments such as seawater and chemical waste.
Sand suction machine is a kind of equipment used to clean, collect and transport granular materials such as sand and gravel. It is widely used in construction sites, port terminals, river dredging, sewage treatment plants, foundry workshops and other fields. It can efficiently absorb sand, gravel, mud, debris and other debris from the ground or water, and transport them to the designated location through pipelines. The main functions of sand suction machine:
①Sand suction: negative pressure is generated by vacuum pump or high-pressure fan to suck sand, gravel, soil, etc. into the equipment.
②Transportation: The sucked materials are transported to the designated location by pneumatic or mechanical conveying.
③Separation and discharge: Some sand suction machines are equipped with filtration systems or sedimentation boxes to separate sand and gravel from air or water for subsequent processing.
During the transportation process, sand often faces problems such as particle sedimentation, pipeline blockage, and severe equipment wear, especially in wet sand, high concentration or long-distance transportation. Due to the high specific gravity and poor fluidity of sand particles, conventional conveying equipment is prone to poor transportation or inefficiency. At the same time, sand causes continuous wear on the inner wall and impeller of the equipment, which greatly shortens the service life of the equipment.
Sand suction machines are optimized in terms of structure and material selection to address these problems. Its core components, such as sand suction pumps, use thickened wear-resistant impellers and pump casings to effectively resist sand erosion; pipelines are mostly equipped with large-diameter hoses or wear-resistant steel pipes to reduce the risk of blockage. For the problem of sand sedimentation, sand suction machines prevent particles from staying by high-flow suction and continuous transportation. At the same time, some models are also equipped with stirring devices or filter residue nets to improve the overall transportation stability. For different environments, stainless steel materials can be used to deal with corrosive media, or mobile vehicle-mounted structures can be used to improve operating efficiency, so as to fully cope with various challenges in the sand transportation process.
The sand suction machine is mainly used to efficiently extract and transport the loose sand in the water or on the surface to the designated location. It is a key equipment in the sand and gravel transportation operation. Due to the high density of sand particles, easy sedimentation, and difficulty in long-distance flow, manual handling or traditional equipment is inefficient. The sand suction machine can play an important role in river dredging, sand recovery in machine-made sand plants, reservoir dredging, and sand and gravel backfilling at construction sites. For example, the fine sand deposited in the river is directly extracted ashore by the sand suction machine; in the sand and gravel production line, the waste sand in the sedimentation tank can be re-transported and reused; in construction sites, it is also often used to transport wet sand from the bottom of the pit to the ground or mixing station, greatly improving construction efficiency.
The price of the sand suction machine varies depending on factors such as type, specification, brand and function. The following is the approximate price range:
Car-mounted sand suction machine: A small and simple car-mounted sand suction machine may cost around US$700-2000. Larger, more powerful, equipped with high-performance sand suction pumps, with greater suction and conveying capacity, and with a higher degree of automation, the price of a vehicle-mounted sand suction machine may be between $3,000 and $7,000 or even higher.
Hose spiral sand suction machine: Generally, the price of a relatively small and lightweight hose spiral sand suction machine is usually around $200-2,000. If it is longer, has a larger diameter, or has some special functions, the price may rise to $3,000-5,800.
Stainless steel sand suction machine: The price of a small stainless steel sand suction machine may be around $700-3,000. The price of a medium-sized stainless steel sand suction machine is about $3,000-5,000. Large stainless steel sand suction machines used for industrial production and with extremely high requirements for corrosion resistance and sealing may cost $5,000-7,000 or even higher.
In short, whether it is wet and sticky river sand or dry and loose construction sand, the sand suction machine can efficiently complete long-distance and high-throughput transportation. Compared with traditional manual handling or mechanical shoveling, the sand suction machine can greatly improve work efficiency, reduce labor costs, and reduce sand loss and environmental pollution during transportation.
