Abrasive Blasting Machine

For effective cleaning or treatment of metal surfaces, an abrasive blasting Machine necessitates a variety of critical equipment pieces. An abrasive Blasting Machine is a method of projecting abrasive particles utilizing compressed air as a power source. It needs a combination of common sense and engineered components to successfully turn compressed air and stationary abrasive particles into an effective cleaning procedure. Each component of an abrasive blasting system contributes significantly to the system’s overall performance. If one component fails for any reason, the entire system will fall short of its projected level of performance. Sand blasting machine is also known as abrasive blasting machine.

Abrasive Blasting Machine Process

The abrasive blasting process is well-known for cleaning steel substrates such as bridges, ships, and other structures from the outside. However, it is a very efficient way of cleaning and treating metal surfaces in enclosed systems. Manually operated sand blasting cabinet with the operator outside the blast chamber to huge rooms with one or more operators working inside the enclosures are examples of enclosed systems. Enclosed systems in this range provide a plethora of standard and custom-designed automated capabilities adapted to specific production and treatment needs. Whether the work is done manually or automatically, inside or outside. abrasive blasting is the process of blasting something with abrasive particles The selection and application of efficient components determine machine productivity.

 Abrasive Blasting Machine Working Principle

There are two types of blasting techniques: suction blast and pressure blast. Suction machines are often little pieces of equipment that are used for light duty tasks or minor cleaning. The suction principle is most commonly used in blast cabinets with limited work areas and less intense blasting requirements. For severe cleaning chores, pressure blast machines are also utilized with cabinets. In blast room applications, pressure blasting is used.

Suction (also known as “venturi”) is a process that draws abrasive from a nonpressurized container into a gun chamber and propels abrasive particles out of an abrasive sand blasting nozzle. A blast gun is typically used in a suction system. two air and abrasive hoses, as well as an abrasive container There’s a nozzle, an air jet, a gun body, and hose connectors on the blast gun. By placing an air jet in front of and in line with a nozzle. A drawing action will be created by compressed air passing through the gun body from the air jet. This forces abrasive into the gun body via the abrasive hose, where it is accelerated into the nozzle.

The velocity and surface impact of suction blasting is one-fourth to one-third that of pressure blasting. As a result, suction blasting is better suited to mild to medium-duty applications. Soft sophisticated metals, where minor deburring, light shot peening, and thin scale removal are required without significant penetration of the base metal, are the most common applications. Automotive and aerospace parts made of aluminium, titanium, and magnesium, for example, are suction blasted.

The use of one hose, rather than two, to feed the nozzle distinguishes pressure blast systems from suction blast systems. Air and abrasive travel with high air pressure and quick speed through a single blast pipe, resulting in severe surface impact.

Abrasive Blasting Machine Applications

A wide range of applications exists for abrasive blasting. Although the most familiar are

 blasting steel bridges and concrete buildings, there are many other common blasting processes

 that improve the appearance of parts, remove unwanted flashing and buns, or add strength to

 high-stress materials. Three of the more prevalent applications are described below.

Surface Preparation 

The process of preparing surfaces for coating materials falls under this application area. Fast cleaning of steel to remove old paint, corrosion, and other impurities are well-known, as is eliminating mill scale that has accumulated on the steel surface during the manufacturing process if it is new steel. When blasting steel, the second most important function is to create a surface profile. The texture created by the impact of abrasive particles on the surface is known as profile, sometimes known as “etch” or “roughness.” To guarantee that their coating material performs as intended, coating producers typically specify the sort of profile necessary.

Steel and masonry aren’t the only materials that can benefit from surface treatment. Fiberglass materials are blasted to expose air bubbles and remove the top layer of glaze (gelcoat). Aluminum, titanium, magnesium, and other advanced metals require the removal of corrosive debris as well as a surface profile if they are to be coated. Newer, less harsh abrasive media are utilized to blast highly advanced materials like composites used in the aircraft and aerospace industries. Airplanes, helicopters, automobile bodies, lorries, and boats are blasted with plastic, wheat starch, and agricultural media at low air pressures to remove deteriorated paint.

Surface finishing

Surface finishing varies from surface preparation in that the goal of abrasive blasting is to improve a product’s look and functionality rather than to prepare it for coating. Deflashing and deburring of mold-formed parts, removal of production impurities, and enhancement of visual aspects are all common surface finishing operations.

Metal foundries, which use sand casting, permanent mould casting, and die casting to make parts, are the most common users of abrasive blasting. Small burrs are nearly usually present in cast parts, and they must be removed for both functional and cosmetic reasons. Blasting cast parts also has the advantage of revealing minute cracks and imperfections that are not easily evident. This benefit is particularly valuable to aircraft repair shops that recondition aeroplane wheels.

Surface Compression

Abrasive blasting, which compresses a surface, is a specialist field that has proven critical to the life of high-stress components. Shot peening is a compression process that uses abrasive blasting. Metal surfaces can have their fatigue strength increased by blasting them with a high-velocity stream of pre-selected round balls. Steel shot, glass bead, and ceramic shots are some of the most common media used in shot peening. The effect of peening is to stretch and compress the surface, minimizing operational stress. As a result, shot-peened parts are more durable than their unpeeled counterparts.
