Types of Sandblaster Systems for Sale

A sandblaster, also known as abrasive blasting, is a device that uses high-pressure air to spray a fine-abrasive material onto a surface to make it smooth or shine. There are various kinds of sandblasting machines for sale. They all work on the same fundamental principle but differ in internal parts and how they apply the abrasive material to surfaces.

• Pressure Pot Sandblaster: It is also known as a pressure feed sandblaster. It is the most common type of sandblaster. A pressure pot sandblaster functions like a spray gun. An air compressor attaches itself to a pressurized container called a blasting pot. The blasting pot holds the abrasive material. Once the air compressor starts working, it pressurizes the blasting pot and forces the abrasive material out of a nozzle at high pressure. This pressure coats the material to be blasted evenly and quickly. A pressure pot sandblaster is suitable for large-scale jobs.
• Suction Blast Sandblaster: It is also known as a suction feed sandblaster. It uses the same principle as the pressure pot sandblaster, but the method of pulling the abrasive material is different. While privy pots use compressed air to push the material out, a suction blast sandblaster uses compressed air to pull the abrasive material from the container. It works well for small to medium-sized tasks and gives more control when working on detailed areas.
• Blast Cabinet: A sandblaster cabinet gives a user a confined space to work. The abrasive material flows freely around the blasted object without interference. A cabinet allows people to work on small objects. The work surface and walls are usually covered in rubber or soft material to prevent damage. Materials to be blasted are placed inside the cabinet through special gloves attached to the cabinet walls. A blast cabinet protects the user because the abrasive material doesn't fly around like in open spaces. It is safe and very suitable for working on delicate parts.
• Wet Blast Pot: It's a unique type of sandblasting system. A wet blast sandblaster works like a pressure pot model, but this one adds water or liquid to the mix. The liquid keeps the dust down and prevents any environmental hazards that may occur from the process. It cools the surface while blasting and helps generate a smooth finish.
• Box-Type Sandblaster: This machine comes in various sizes and is suitable for large objects. A box-type sandblaster works continuously and has an automatic feeding system. Users have to feed the object a single time, and the box does the rest. It is great for working on big pieces but not ideal for tasks that require a lot of detail.

Specification and Maintenance

The performance of a sandblaster system is decided by its specific parts. They all need to be maintained for consistent efficiency.

• Compressor

  The hoses and fittings of the air compressor should be examined for any leaks or signs of wear. The compressor oil should be checked and changed if it isather than two-thirds full and looked cloudy. Air filters need to be cleaned or replaced monthly and hoses need to be inspected for kinks or damage.

• Gun

  Gun maintenance involves cleaning, lubricating, and inspecting it regularly. After each use, tap the gun on a metal container to shake out any residual media then blow it out with compressed air. Every few weeks, disassemble the nozzle, tip, and trigger components and clean them with solvent. Apply a light coat of lubricant to moving parts. Check for worn nozzles and tips and replace them if they show significant wear. Inspect the trigger and cable for fraying or damage and replace them if needed. Following this schedule will keep the sandblasting gun functioning properly and extend its life.

• Nozzle

  Sandblasting nozzles should be cleaned regularly to maintain optimal performance. After each use, remove the nozzle from the gun and clean out any media buildup with a wire brush or nozzle cleaning tool. Inspect the nozzle for wear or damage, paying particular attention to the tip, which wears the fastest. If the nozzle shows substantial wear or cracks, replace it. Store nozzles in a dry, protected location away from direct sunlight or heat sources. Following these simple maintenance steps will help extend the life of sandblasting nozzles and keep them functioning effectively.

• Blast cabinet or pot

  It is important to clean the interior and exterior surfaces of a blast cabinet or pot regularly to remove any buildup of blasting media and debris. Use a shop vacuum to remove spent media from the cabinet base and floor while taking care not to damage the recovery system. Wipe down all surfaces inside with a solvent-soaked rag to remove contaminants. The outside of the cabinet should be vacuumed and then washed with soapy water to remove dust. Follow up by applying a corrosion inhibitor to exposed metal surfaces. Cleaning frequency should be based on usage but ideally, the cabinet should be thoroughly cleaned at least once per week. A consistent cleaning schedule will prevent cross-contamination of media, maintain optimal reclaim function, and extend equipment life.
