When performing blast preparation applications it’s essential that both the compressor and nozzles remain free from oil and moisture contamination.

Abrasive Blasters

Abrasive blasting utilizes pressure-driven media such as sand, steel grit, or garnet to propel against a workpiece’s surface with media such as sand, steel grit or garnet and remove rust, corrosion, scale pitting, rough spots or any other imperfections in metal parts before they undergo refinishing or painting. Furthermore, deburring edges is another benefit as this reduces handling hazards while helping cut or molded parts retain their shapes over time.

Blasting operations take place inside a containment system known as a blast cabinet or room. These cabinets are constructed by using various sheet metal fabrication, casting, welding and machining processes that create sides, legs, doors, windows, glove ports, grating or screens and gun holders made out of sheet metal. Additional components may include turntables to position workpieces before blasting begins; blast guns equipped with see-through windows so operators can view operations; foot pedal or treadle controls to manage media flow and so forth.

Compressed air is delivered from a compressor to one or more blast pots, pressurized containers that contain abrasive media. Each blast pot features a pop-up or metering valve with which media can be released into a blast hose connected to the blast gun located within its cabinet and fired at workpiece using foot pedal or treadle trigger for firing at increased impact energy and cleaning effectiveness.

The type of abrasive blasting equipment selected depends on both application and production volume. Steel shot can be reused multiple times while sand or coal slag must be replenished after each use. Furthermore, different types of abrasives can be used either wet or dry blasting processes. Abrasives come in the form of minerals (such as silica), glass-based products like ceramic or sodium bicarbonate or chemical solutions like sodium bicarbonate. Silica is one of the more popular mineral-based abrasives; coated varieties are available to prevent dust inhalation which could potentially lead to debilitating lung conditions like silicosis. Mineral-based abrasives like garnet are more expensive but deliver comparable performance. Their particles are propelled out of the nozzle at high velocity, so appropriate safety equipment such as padded headgear, hearing and eye protection and respirators is needed to protect operators.

Wheel Blasters

Wheel blast machines provide a simple yet efficient solution for cleaning larger products such as castings, machine parts and structural elements prior to coating with an anti-corrosion layer of corrosion-protective paint or powder coat. By converting electric motor energy into kinetic abrasive energy using a rotating turbine wheel, they convert electric motor energy into kinetic abrasive energy for use against castings, machine parts and structural elements with variable distance between blast wheel and workpiece allowing users to customize blast patterns that adjust size, shape and location of hot spots on workpiece surfaces allowing operatorss for fine-tuning control of blast patterns when de-rusting or cleaning prior to painting or coating applications.

Wheel blast systems are also designed to accommodate for the easy addition and removal of media from a hopper, using an automated feed system, with good quality abrasives recirculated back into production as needed. A separate air-wash separator blows dust and fine abrasive into a waste hopper; any good quality abrasive remains within the system for reuse.

Wheel blast systems tend to be less costly than other forms of Sandblasting Equipment and are frequently the go-to choice in metal fabrication operations. A wheel blast system could easily clean 320 truck rims per eight hour shift with sufficient equipment setup.

However, basic wheel-blast operation and maintenance have changed little over time, making it critical that workers pay close attention to ammeter readings and add abrasive as needed for optimal performance. An inexperienced operator on another shift could accidentally dump too much coarser particle-sized abrasive onto their system, altering media mixes too drastically for effective wheel blasting.

Some wheel blast systems can even use stainless steel shot, which works great to descale forgings and clean castings of aluminum oxide coatings. Furthermore, its round abrasive helps stress-relieve components while being an environmentally friendly choice over other forms of blasting media.

Glass bead blasting can provide another option for stainless-blast applications. These systems use compressed air to propel small glass beads across surfaces to scour and clean, which can then be reused to decrease blast time and involvement from an operator.

Suction Blasters

Suction sandblast cabinets differ from wheel and pressure systems in that they use vacuum technology to draw media into their gun and deliver it directly onto a work surface. Blasting media is stored in a canister connected directly with the blast gun via hose and nozzle.

Vacuum blasting can be an extremely effective alternative to dry abrasive blasting when working with delicate surfaces or limited air resources, as it produces much less dust. The process is quick, quiet and produces minimal dust emissions from its use compared with dry abrasive blasting; its blast gun uses a specialized nozzle to deliver high-speed mixture of air and sand (known as an abrasive) directly into the work area leaving minimal residue behind; used sand is automatically separated from dust/loosened debris after use and reused many times over.

Suction systems are generally easier to operate and maintain than pressure systems, as their guns require fewer parts and wear out more slowly; however, the nozzles, blast gun body and control piping must still be regularly checked for cracks and leaks. Nozzles made from hard materials like boron carbide, alumina or pure WC may wear down faster due to lower media delivery velocity; this wear can sometimes be compensated for by slowing media delivery velocity.

Lower velocity also necessitates that the nozzle be kept closer to the workpiece, decreasing blast stream size and restricting how much blast media coverage there is on the workpieceslowing down cleaning rate and productivity rates as a result.

Pressure systems offer greater impact energy to penetrate more layers of paint, rust or coatings than suction systems can due to their higher impact energy output. Furthermore, pressure systems can more easily handle heavier blast media, like steel shot or cut wire shot that may be difficult for suction systems to lift and propel. Finally, pressure systems offer more precise pressure level control, which allows the operator to target specific areas for treatment or removal more precisely and target specific contaminants more rapidly compared to suction systems thereby shortening job times overall.

Direct Pressure Blasters

Sandblasting Equipment refers to systems or machinery that uses compressed air or water to activate blast media (such as sand, metal shot or ceramic beads) before projecting it against surfaces to clean or modify them. This equipment typically consists of a blast pot, gun that mounts pressurized media and blast wheel/nozzle.

Pressure pot sandblasters utilize a pressurized canister of abrasive material (such as sand) connected via hose to a gun via special trigger mechanism. A trigger on the gun can then be pulled to release the abrasive from its container into its barrel of the blasting gun, also known as gravity fed blaster due to how gravity supplies its supply.

Gravity propulsion drives abrasives out of their guns, impacting surfaces to be cleaned or blasted with force to dislodge debris and expose fresh surfaces on objects to be cleaned/blasted.

Pressure systems tend to be used more frequently for industrial applications than suction or cyclone systems; however, these can sometimes be utilized on smaller jobs as well. While pressure sandblasting equipment tends to be more costly than its alternatives, increased efficiency and decreased downtime may save money in labor costs in the long run.

Sandblasting Equipment allows users to employ various abrasive media types, including glass beads or nonmetallic media, for more accurate cleaning results and smoother surfaces than standard sand.

No matter what abrasive is used, sandblasting can create significant wear on internal components and system accessories. Blast equipment needs to be regularly inspected, maintained, repaired and media wear parts checked or replaced as needed to ensure consistent performance, quality and safety. Workers should use personal protective equipment (PPE), enroll in formal blast training if possible for optimized time-management and improved work practices, as well as being mindful of confined space requirements when operating blasting equipment in small spaces.
