Abrasive Blasting Machine

Introduction Abrasive Blasting Machine

An abrasive blasting machine is the methodology of spraying abrasive media usually silica sand & steel grit with a high pressure on an exterior in order to annihilate contamination of materials such as rust, paint, salt, oil, etc. It even strives to develop a profile (roughness) on the exterior of the metal so the paint adheres better.

Abrasive blasting machine is a procedure of machining that utilizes loose abrasives. The abrasive stream (also known as media) is driven by compressed air & centrifugal force (produced by a spinning wheel) against the jobpiece's exterior at heightened speed. Sand blasting machine & shot blasting machines are two popular kinds of abrasive blasting machine. Sand blasting may affect the usage of varied abrasive media in addition to sand. Sand blasting & shot blasting machine approaches are quite similar. Shot blasting, on the additional hand, is far more aggressive than sand blasting. Another distinction is certain shot blasting usually utilizes centrifugal force to accelerate the abrasive stream, whereas sandblasting utilizes compressed air. We are one of the best abrasive blasting machine manufacturer in India.

Abrasive blasting is the preferred approach of surface preparation in new shipbuilding because of its economic & performance benefits. The method delivers the appropriate surface roughness & improves the exterior area, two critical factors in reaching physical & chemical bonding between a steel surface & an organic thermal spray gun coating. Adhesion, in fact, is the key to coating usefulness, resolving whether the coating is just a thin sheet of material lying on the substrate & whether it becomes an essential part of the substrate. Abrasive blasting, however, even demands a significant amount of labor, & its efficiency relies primarily on the blaster’s skill. Completing the economic, efficiency, & productivity benefits from abrasive blasting demands the correct selection & matching of the abrasive, sand blasting nozzle, air pressure, & abrasive/air mixing ratio. Especially for new shipbuilding, there is a requirement to determine how to control the profile height by careful selection of the primary variables such as abrasive size & hardness, or nozzle pressure. 

Abrasive Blasting Process

Abrasive blasting means propelling a streamlet of abrasive media at elevated velocity against an exterior utilizing compressed air, liquid, steam, centrifugal wheels & paddles to clean, abrade, etch, & otherwise transform the most earlier arrival & necessity of the exterior. It is utilized in a broad scope of industriousness for numerous dissimilar objectives, including cleaning exteriors like steel, bricks, adhesive & concrete. The most common approach utilizes compressed air to move abrasive media from a blast pot, via an abrasive blasting hose to a nozzle certain is manually handled by the operator. Abrasive blasting machines like centrifugal wheel systems & tumblers are likewise employed. Blasting is typically accomplished in encompassed atmospheres like blasting rooms & sand blasting cabinets, & on available sites, for instance on buildings, bridges, tanks, boats & mobile plants.

Abrasive Blasting Machine Working

Abrasive blasting machines normally need an elevated-volume air supply (usually in 90-100 psi .); a container & pressure vessel to hold the abrasive; a metering device to control air-to-abrasive ratio & flow; a shapeable hose to provide the abrasive, & a hand-held nozzle to desire the abrasive media the jobpiece. Many portable sand blasting machines furthermore have large hopper-fed storage tanks whichever allow multiple blasting operations from a single source of supply. The first step in the abrasive blasting process is to determine what kind of material & equipment are necessary to complete the task. It is also necessary to clean the exterior upon whichever you will be operating to ensure certain there is no residue which will result in a marred finish.

Types of abrasive blasting machine

Dry Blasting:- There are two procedures engaged for dry-blast cleaning; mechanical blasting & air pressure blasting.

• Mechanical Blasting: - Mechanical blasting is frequently performed utilizing cabinet-type blasting machine. It is obtainable in batch, semi-automated, & automatic variants. The cabinet often holds one & more blast wheels, whichever employ centrifugal force to guide the abrasive toward the jobpiece. The shot blasting wheel is positioned to guarantee optimal coverage & blast convention efficiency while taking into account jobpiece design.
• Air Pressure Blasting: - Air pressure blasting is the procedure of affecting abrasive to a exterior utilizing compressed air. Air pressure blasting engages either direct pressure & an induction mechanism, whichever could be siphon & gravity-based.

Wet Blasting: - Wet blasting concerns elevated velocity, compressed air propulsion of a slurry orchestrated onto a jobpiece. The slurry is typically composed of acceptable abrasives discontinued in chemically dined water. It is normally kept under constant agitation to handle the abrasive from dropping. As with straightforward pressure dry blast machine, compressed air is supplied into the vessel housing mixture at the exact pressure of the blast hose. Offsetting the pressure allows the abrasive mixture to flow via mixing valve & into the airline. A full discharge valve, discovered betwixt the sand blasting hopper & the mixing room, regulates the abrasive flow.

Use of Personal Protective Equipment

• Everyone on the job site needs to wear PPE; the type & level of protection are specified by the assignment function.
• At a minimum, everyone on the site is required to wear steel-toed work boots, safety glasses, and a sand blasting helmet. Hearing protection may even be needed.
• Unnecessary to say, blast operators require more protection. Specially-designed blast suits are unrestricted & deliver a reasonable base of protection.
• Leather gloves are a must when spraying abrasives at this velocity.
• Abrasive blasting equipment makes a lot of noise, so approved hearing protection such as ear plugs & ear muffs or an abrasive sand blasting helmet is required.
