Types of rotary table sand blastings

A rotary table sand blasting is an abrasive blasting process that uses compressed air or other gasses to propel fine sand or other abrasives against a surface to be cleaned or polished. This machine is widely used in the industry for surface preparation, cleaning, and polishing of various metal parts. There are mainly two types of rotary table sand blasting machines for use in the industry.

• Heaps type: In this blasting machine, the work surface is at the same level as the horizontal sand blasting hopper. Hence, this machine is also called the same-level rotary table sand blasting machine. Because of the workpieces' smooth transition from the blasting area to the out-of-blasting area, this machine is excellent for use on flat workpieces. However, the use of this machine is limited to workpieces with a small height ratio.
• Lower hemi-spherical type: This rotary sand blasting machine has a hopper that is hemispherical and located below the work table. It is an ideal machine for use on workpieces with large height-to-length ratios. In this machine, an operator can load a higher number of workpieces. The pre-separator and the cyclone dust collector on this rotary blasting machine help segregate the blasting abrasive and dust. While the segregated dust goes to the filter bag for disposal, the reusable blasting abrasive goes to the hopper.

Specification and Maintenance

Some basic specifications and their maintenance requirements are as follows.

• {'> '}Compatible Blasting Media

  The rotary sandblasting cabinet is constructed to work with specific types of blasting media. Common media include fine sand, aluminum oxide, glass beads, walnut shells, or silicon carbide. Each type of media has unique properties and effects on surface finishing. Different blasting media affects the machine's performance, efficiency, and the quality of the surface finish. For optimal results, it's crucial to use the recommended blasting media. Using an incompatible media can damage workpieces or yield subpar results.

• /h3>{'> '}Cabinet Size and Workpiece Dimensions

  The size of the sand blaster cabinet determines the maximum size of workpieces that can fit inside for blasting. This involves both the cabinet's internal space and entry openings. Oversized parts won't fit into the cabinet, making any job impractical. Conversely, workpieces that are too small may move around and pose a safety hazard. Therefore, it's essential to match the dimensions of the workpiece with the blasting cabinet before starting any job. Failure to consider size limitations may result in difficulties or potential accidents during the blasting process.

• {'> '}Operating Pressure and Flow Rate

  Sandblasting machines work by propelling abrasive media at high pressure to remove surface contaminants. The pressure at which the air compressor is set affects media velocity and impact force on surfaces. Higher pressure results in greater blasting power for tougher contamination removal. However, increasing pressure also raises media consumption, machine wear, and potentially rapid workpiece degradation.

  Therefore, it is crucial to determine the optimal compressor pressure for each job. This depends on the type and amount of surface contaminants on the workpiece. Prioritizing the minimal effective blasting pressure conserves abrasive media, prolongs equipment lifespan, and protects workpiece integrity.

• {'> '}Dust Collector System

  The dust collector plays an essential role in the sandblasting machine by filtering out fine dust particles generated during the blasting process. Its main job is to capture this harmful silica dust and prevent it from being released into the surrounding workspace atmosphere. Proper functioning of the dust collector protects both operators and nearby personnel from exposure to hazardous silica. Continuous exposure can pose significant health risks over time.

  It's important to routinely check and maintain the dust collector, ensuring its filters are clean and working correctly. Neglecting the dust collector may lead to filter clogging, reduced extraction efficiency, or total system failure. This could allow toxic silica dust to accumulate in the air, putting everyone at risk. Regular monitoring and care of the collector prevents environmental contamination and safeguards worker safety.

How to choose rotary table sand blastings

• Workpiece size and weight

  Three-quarters of the worlds' machines are stamped capable of handling specific sizes and weights. It includes tables to determine the maximum weight of a workpiece and the size that fits. It is crucial to choose a rotary table sandblasting machine whose capacity matches or exceeds the size and weight requirements. Failure to do so can result in damage or collision during operation, which may cause serious injury.

• Blast media compatibility

  Different sandblasters work with various types of blast media, such as sand, aluminum oxide, glass beads, etc. Ensure the rotary table sandblasting machine is compatible with the specific blast media to be used for optimal results and equipment maintenance.

• Noise level

  Sandblasting machines can be pretty noisy, and the sound level is shown in decibels (dB). The higher the decibel level, the louder the machine. It is essential to consider the noise level of the sandblaster and choose one that is quieter, if possible, to help minimize noise pollution and protect hearing.

• Controls and automation

  Some sandblasters have simple manual controls like knobs and levers, while others have more advanced automated systems for precise control. Consider the type of control system desired and choose the machine with the appropriate level of automation to match specific applications and preferences and ensure ease of use and effective results.

• Operator safety features

  These include pressure relief valves, safety interlocks, and fire suppression systems; operator safety aspects are paramount when using a sand rotary table machine. These focus on the operator's protection and may include various safety features that are essential for protecting the user. Choose a machine equipped with these operator safety features so that the operator is well-protected and avoids potential accidents and hazards during use.
