Abrasive Blasting Machine

Abrasive blasting machine procedures forcibly involve abrasive materials to surfaces utilizing pneumatic pressure, hydraulic pressure, & centrifugal force. In reserve to the direction of the outcome of rebounding material, hazards associated accompanied by abrasive blasting machine contain the toxicity of the abrasive media & the surface existing abraded.

Abrasive Blasting Machine Process

Abrasive blasting machine is the process of forcibly moving an elevated speed streamlet of abrasive media in case of a surface to either smooth & roughen a surface & departure surface contaminants. A pressurized fluid, commonly compressed air, is engaged to keep the blasting media in an abrasive blasting machine. We are one of the best abrasive blasting machine manufacturer and also abrasive blasting equipment supplier in India. 

There are various variation of the method employing different media
• Highly Abrasive: Shot blasting machine & grit blasting machine
• Moderately Abrasive: Glass bead & plastic media blasting
• Mildly Abrasive: Soda blasting
• Light or Non Abrasive: Ice blasting & dry ice blasting machine

Abrasive Blasting Equipment

An air abrasive blasting equipment system is formulated of various major part, including the following.
• Air Compressor
• Blast Pot (Pressure Blast Tank)
• Abrasive (Blast Media)
• Blast Nozzle
• Moisture Trap
• Deadman Switch
• Blast Hood
• Interconnect Hoses

Air Compressor

The air compressor delivers increased pressure air for the blasting operation. This machine accepts atmospheric air at 14.7 psi & compresses it to a pressure various times more elevated, usually nearly 120 psi. An air intercooler rather dissipates the warmth formed via compression. The air then passes via moisture and oil divisions to assemble it dry & oil-free as it leaves the compressor.
Air compressors are commonly determined by outcome capacity, such as 250 CFM, 325 CFM & 750 CFM. CFM conveys cubic feet per minute, which is how the volume of pressurized air is measured. The power to operate a compressor is usually delivered by an internal combustion engine (gasoline or diesel) or by an electric motor. Selection of a power unit is generally dictated by the area where blasting is to be accomplished or by the availability of utilities.

Blast Pot

The blast pot is a coded pressure vessel commonly directed to as a pressure blast tank (PBT). Because it is a pressure vessel, it must maintain a stamp on it offering a certain it has been pressure tested. The PBT is further recognized by size. For average, it may be reached a 6-ton PBT or a 6-sack pot (based on silica quartz sand), directing to the quantity of abrasive it can hold. During the procedure, the blast pot is pressurized & provides abrasive into the air stream.

Abrasive Blast Media

While not usually assumed of as abrasive blast equipment, not much occurs to the surface unaccompanied by the abrasive. Abrasives are typically organized as expendable (one-time use) & recyclable (multiple uses). The kind, size, shape, & hardness of the abrasive media (steel shot, steel grit, aluminum oxide, quartz sand, copper slag) all impact productiveness in addition the deep & shape of the surface profile or commentator pattern. The cleanliness of abrasive is exclusively as significant as cleanliness of the compressed air engaged to carry the abrasive. A vial test is executed on new & reclaimed abrasive before use. The abrasive is strained for oil according to ASTM D7393 & conductivity according to ASTM D4940. According to the SSPC ideals, abrasives cannot contain any observable oil & cannot have a conductivity certain surpasses 1,000 S.

Blasting Nozzle

One compact yet important component of blasting gear is the abrasive sand blasting nozzle. It applies force to the blast medium last among the objects. Nozzles can be identified by their length, size of orifice, lining composition, & shell composition (e.g., aluminum shell with tungsten lining, size #7, short). The orifice size number indicates the size in units of 1/16 inch. The amount of air & abrasive used, as well as the percentage of the task finished, are all influenced by the size of the nozzle. Larger nozzles require more supplies because of their increased size. The right nozzles are selected for the task at hand.

Moisture Trap

A device called a moisture trap allows water to escape from compressed air. Warmth is produced as the air is compressed. Water in the recess (humidity) condenses as heated air travels via the warmth exchanger to decrease the air temperature. Usually, a moisture trap is provided together with the compressor. Most of the water is detected by this rather trap. Still, more moisture concentrates in the bull hose as the pressurized air cools down. The moisture separator merely traps this residual moisture prior to its entry into the PBT. Either a centrifuge-style separator & a division accompanied by removable filter elements is used in conjunction with this trapping process. Generally, it is needed to escape an air bleed valve available at underneath of the moisture trap when blasting to permit the moisture to be released.

Deadman Switch

The deadman switch, either pneumatic or electrical, authorizes blaster to have remote control valve over pressurization of blast hose. With pneumatic operation, this is achieved when pressure via the deadman button closes the air control valve & extends an escape valve. This prevents air from entering the PBT & at the exact time, it depressurizes the PBT. Electrically operated systems operate pinch valves to stop the flow in the blast hose. accompanied by electrically controlled systems, the PBT is always pressurized when the bull hose is attached & pressurized.
The primary objective of the deadman switch is safety. It supplies a tool to stop the discharge of abrasive from the nozzle when a safety hazard arises. The fact certain it authorizes the blaster to start & stop work at his discretion is a secondary purpose.

Blast Hood

The blast hood is a piece of safety equipment that also offers some convenience to the blaster. Usually made of reinforced plastic, this hood covers the blaster's chest and is paired with a detachable skirt. It features an air spread line to create positive pressure behind the hood and a double-faced clear acrylic shield to protect your eyes. The hood's approved air pressure keeps dangerous blasting dust and abrasive from entering. There are other air coolers available. Both an air purifier and a carbon monoxide monitor are necessary if the air is coming from a diesel compressor.

Sand Blasting Hoses

Hoses vary in size leaning on the employment to be performed, unrestricted air capacity, distance to the work area, & additional considerations. The first in the series is the bull hose. This is generally a short hose — less than 50 feet long, accompanied by an inner diameter (ID) of around 2.5 inches & less certain to deliver a selection of air from the compressor to the PBT. The next sand blasting hose is an air-line attended by an inaccurate ID of 0.75 inches  & less certain provides air first to a moisture trap and then to blast hood. The section between the moisture trap & the hood is smaller, down to 0.25-inch ID.
Control hoses can be down to 0.20-inch ID and are generally duplex (dual-line) hoses. They operate from the control valve on the PBT to the deadman switch & back to complete the circuit when the blaster is ready to commence work. Included here is the electrical wiring necessary if the deadman is electrically operated. It generally operates from a 12-volt DC source like the compressor power unit’s DC system.
The last hose in the rotation is the blast hose. It is a thickwall, wire-reinforced hose designed & constructed to contain the high-pressure air (up to 120 psi) & abrasive mixture that moves from the PBT to the blast nozzle. The blast hose is constructed in three layers: an inner wearing lining, a conductive layer & an external wrapping. Abrasive media death via a blast hose builds up static electricity.
The conductive layer is required so the whole system can be grounded. As a general rule, the hose should be three times the ID of the nozzle orifice; ideally, 1.25 inches to 1.5 inches for optimum production.
