Advantages and Application Scenarios of Mobile Sand Blasting Machines
A. Advantages of Mobile Sand Blasting Machines
1. Flexible movement, no need for workers to handle the workpieces
Equipped with wheels for movement, it can be pushed, pulled, or towed for transfer. The workpiece remains stationary while the sand blasting machine moves: large components, fixed equipment, on-site components do not need to be disassembled and hoisted, eliminating the cost of workpiece transportation, suitable for construction sites and on-site construction.
2. High working pressure, strong processing capacity
Pressurized high-pressure sand blasting, working pressure 0.6-0.8 MPa, can reach Sa2.5 to Sa3 rust removal standards, can quickly remove rust, oxide scale, old paint layers, welding slag, suitable for pre-treatment before heavy corrosion protection.
3. Simple operation, quick deployment
Integrated whole machine, can start work on-site by connecting air compressor and adding abrasive materials without building a sand blasting room; can operate outdoors in the field, transfer quickly, suitable for emergency repairs and maintenance projects.
4. Strong adaptability to working conditions
Can handle high and low positions, corner welds, and irregular components; pressure and abrasive output can be adjusted, rough rust removal and local fine cleaning can be achieved.
5. High cost performance
Compared to building a sand blasting room, the initial investment of mobile sand blasting machines is lower; suitable for scattered, on-site, and non-batch surface treatment; abrasive materials can be recycled and reused, reducing material consumption.
Disadvantages: Open-air operation will generate dust, outdoor operation requires protection; requires a matching air compressor.
B. Application Scenarios of Mobile Sand Blasting Machines
1. Steel Structures and Bridge Engineering
Rust removal and renovation of steel structures for bridges, factory steel frames, supports, towers; on-site construction of outdoor steel structures.
2. Tanks, Pressure Vessels, Pipelines
Rust removal and old paint removal of external walls of oil tanks, large pipelines, oil and gas pipelines, water pipelines on-site; on-site renovation of storage tanks, no need to dismantle and transport the tank body to the factory.
3. Maintenance of Construction Machinery, Mining Equipment
Renovation of excavators, tower cranes, mining machinery, heavy equipment; on-site surface treatment for major overhauls, no need to disassemble the entire machine.
4. Ships, Ports, Water Engineering Facilities
Local rust removal and maintenance of ship bodies, steel structures of docks, gates, water engineering components on-site sand blasting.
5. Renovation of Buildings, Stone, Cultural Relics
Stone engraving, stone monument processing; cleaning and removing old coatings of exterior walls, ancient building components; concrete surface treatment.
6. Factory Site Maintenance
Large molds, large equipment, production line components that are inconvenient to transport into the sand blasting room, on-site sand blasting cleaning, removing welding slag, surface treatment before coating.
7. Other
Drilling platforms, amusement facilities, large ironwork, thermal spraying pre-treatment, old component renovation.
III. Scenarios Unsuitable for Mobile Sand Blasting Machines
1. Large quantities of small workpieces (prefer to use shot blasting machines / sand blasting rooms)
2. Precise thin-walled parts, sensitive products afraid of dust pollution (prefer wet closed sand blasting)
