Blast Cleaning Equipment

Blast cleaning equipment is a cornerstone in various industries, offering a robust solution for surface preparation and finishing. From the construction industry to specialized engineering tasks, the importance of this cleaning equipment remains unparalleled.

Introduction to Blast Cleaning Equipment

Blast cleaning equipment encompasses a range of machinery and accessories designed to propel abrasives against surfaces, ensuring thorough cleaning, surface prep, or coating removal. Depending on the application, various blast systems can be employed, including abrasive blasting, sandblasting, dry ice blasting, and water blasting.

Types of Equipment and Their Applications

Sand Blasting Machine: An industry-standard, this machine uses sand as the abrasive medium. It’s excellent for rust removal and preparing surfaces for painting.
Airblast Machines and Sandblast Kits: These are portable, often mobile units, allowing for flexibility in application, be it benchtop tasks or larger industrial projects.
Abrasive Blast Machines: These are heavy-duty machines that can utilize various abrasives, from grit to more specialized materials, allowing flexibility based on the surface and finish required.
Blast Cabinets: These are enclosed units where the object to be treated is placed inside. They’re perfect for smaller parts and offer a contained environment, minimizing the spread of abrasives.
Dry Ice Blasting: This is a unique form of cleaning where solid CO2 pellets (dry ice) are used. It’s particularly efficient for cleaning oil, paint, or other stubborn residues without leaving moisture behind.
Blast Rooms: For larger parts or more significant projects, blast rooms provide a contained environment where larger objects can be treated.
Water Blasting: This method uses high-pressure water. It’s an excellent choice when moisture isn’t a concern and offers a clean, dust-free environment.

Tumble Blast Machines

Tumble blast machines are the most common equipment choice for batch cleaning high volume or non-delicate parts. The tumbling action of the belt conveyor ensures that parts are continually exposed to the blast stream and completely cleaned. For easy unloading, simply reverse the mill and the parts are unloaded onto an external conveyor or bin. Tumble Blast machine range in size from 3 cubic feet to 72 cubic feet.

Spinner Hanger Machines

Spinner Hangers are an ideal choice for both batch and continues cleaning of fragile or large parts, that cannot be tumbled. This style machine hangs parts in front of the blast wheels and rotates them to ensure proper cleaning. Spinner Hangers are available in multiple configuration able to blast multiple light pieces and large heavy pieces weighing several thousand pounds. Another type of “Hanger” style blast unit, is a Monorail Blast Machine. This style machine utilizes an overhead conveyor to transport parts through a blast chamber to clean all sides in a single pass.

Roller Conveyor Machines

Roller Conveyor machines are extremely universal, able to blast all sides of complex work pieces in a single pass. These machine are available in many configurations ranging from 4 blast wheels, up to 18 blast wheels. Typical work pieces are plate, beams, and complex weldments.

Turn Table Blast Machines

Turn Table blast machines allow for a wide variety of parts to be cleaned in an economical fashion. Parts weighing as little as 20 pounds to more 20,000 pounds can be processed in Table Blast units. These machine are extremely useful in fabrication or service facilities that have varying part sizes and shapes.

Rotary Drum Blast Machines

Rotary Drum blast units are similar to a tumble blast machine, except there are no moving mill part. The drum or barrel itself rotates, tumbling parts into the blast “hot spot”. These machines are perfect for small parts that can get caught or pinch in standard steel mill tumble blast machines. Rotary Drum machines range in size from 5 to 34 cubic feet of capacity.

Wire Mesh Belt Machines

Wire Mesh Belt machines are one of the most versatile blast machines. This style machine is designed to blast a large variety of parts, that will fit into the machines designated work envelope. Ranging in standard sizes with 4 wheels to 8 wheels and 12″ to 60″ belt widths, even the most complex parts with hard to reach areas can be effectively cleaned. Wire Mesh Belt units can be installed for batch processing of flat stock or cast parts, or continuous blasting of high volume parts that are too small or delicate for Conveyor or Tumble style machines.

Accessories and Components

Equally important as the blast equipment itself are the accessories and components. These include hoses, couplings, metering valves, nozzles, and guns. The quality of these accessories often determines the efficiency and performance of the blast cleaning system. Dust collectors are crucial in ensuring a clean working environment, while moisture traps ensure that water doesn’t interfere, especially in airblast systems.

Standards and Quality

Given the critical nature of surface prep in many industries, adhering to standards is paramount. Quality blast cleaning equipment is designed with industry standards in mind, ensuring safety, efficiency, and performance. Many brands, identifiable by their distinct logo, such as Graco, have years of experience, ensuring customers get top-notch solutions tailored to their needs.

Conclusion

In the world of surface preparation and treatment, blast cleaning equipment stands out for its versatility and efficiency. Whether it’s prepping a surface for a fresh coat of paint, removing rust, or cleaning away oil and grime, these machines and their accessories have become an industry staple. As technologies evolve, the range of products and solutions in this line will only expand, offering better, more efficient methods for surface treatment across various industries.
