Inventor Benjamin Chew Tilghman

Invented October 18, 1870

The shot blasting machine is an equipment used to reinforce, clean or polish any metal surface or metal. Shot blasting, also known as abrasive blasting, more commonly known as sandblasting. Historically, shot blasting is not a relatively modern concept, the first shot blasting machine in the world was patented (US patent 108,408.) by Benjamin Chew Tilghman (1821–1901),[1] an American soldier and inventor,[2] on October 18, 1870.[3]

Shot blasting is a technique in which a selected class of abrasive particles is used to remove material from a surface at a high speed (65 -110 m/s) corrosion rate. It is the operation of forcing the abrasive stream to the surface under high pressure to smooth the rough surface, roughen the smooth surface, and shape or remove surface contaminants. A pressurized fluid (usually compressed air), or a centrifugal wheel is used to propel the blast material (commonly referred to as the medium).

Overview

Shot blasting is a process that treats metals to remove rust, grease, scale, and other irregularities to create a smooth surface for applying a finishing surface. During this process, ssome abrasive material is blasted onto the surface and depending on the surface being treated, they may be sand, beads or water. It is important to create a smooth and clean surface to apply the final surface treatment, like, powder coating, to the metal surface to achieve a high-quality, beautiful and durable surface treatment. China sand blasting machine is a mechanical method that uses centrifugal wheels to propelling the abrasive to remove surface and other impurities from the surface of steel applications. In general, blasting prior to finishing serves three primary purposes:

· Cleans and descales surfaces

· Increase texture to enhance paint adhesion

· Properly reduces maintenance costs by extending coating life

History

Benjamin Tilghman was a general in the army and saw the effect of wind-blown sand on windows in the desert. This might be the basis of his shot blasting machine invention.

On October 18, 1870, Tilghman filed a patent, titled “Improvement in cutting and engraving stone, metal, glass, etc.”, in the US (US patent 108,408.), detailing many unique applications of the technology, such as sharpening files, carving bottles, cleaning boilers or turning The wood grain comes out. Later that year, a patent was issued in the UK.

Methods

Broadly, there are two methods of shot blasting machines: air blasting and mechanical blasting (also known as airless blasting, and wheel blasting).

Mechanical blasting

In this system, the abrasive is propelled by fast rotating impellers driven by power.

Air blasting

In this system, the abrasive is propelled through a nozzle by compressed air (mechanical blasting is more widely used).

How Shot Blasting Machine Works?

During the working process of the shot blasting machine, the electrically controlled transport system conveys the object items into the shot blasting chamber, and its surfaces are hit and rubbed by powerful and dense steel shots from different coordinate directions. The oxide scale, rust layer, and dirt on the surface quickly fall off.

Used blasting media and contaminants (pill dust mixture) falling into the screw conveyor, then reclaim them into the bucket elevator and then into the air wash cleaner system, the cleaned abrasive get into the storage hopper to recycle, the residual will get out of the recycling system from the air wash cleaner system. The dust is collected to the dust collector system by the exhaust pipe, the purified air is discharged into the atmosphere, and the particulate dust is captured and collected in the dust collector, and then discharged into the atmosphere is clean and pollution-free air.

How to Choose the Abrasive of Shot Blasting Machine?

Metal abrasives include steel shot, steel grit, iron shot, iron sand, stainless steel shot, stainless steel sand, steel wire cut shot, and stainless steel wire cut shot, etc.

Each type of shot blasting machine equipment requires different types of abrasives. If the final type of abrasive needs to be determined, it also depends on what kind of workpiece the shot blasting machine is blasting and the desired shot blasting effect. The size of the workpiece is different, and the abrasive used is also different, so the specific type of abrasive used depends on the situation.

The larger the abrasive diameter, the higher the surface roughness of the workpiece, but the shot blasting efficiency is also high; the abrasive diameter should be selected according to the surface roughness of the part. The shot blasting efficiency of other irregularly shaped steel shots or cut wire shots is higher than that of spherical shots, but the surface roughness is also higher.

Choose the abrasive with a moderate hardness to achieve a good application effect. Suitable abrasive hardness and excellent resilience, so that the abrasive can be projected to every part of the shot blasting machine chamber, and then reduce the blasting time.

 Technical support:

1. The engineer team use 3-D dynamic simulation design blast turbines layout to ensure that the steel shot ray can cover the surface of the steel structure 360 degrees.

2. The equipment adopt pneumatic control abrasive distribution system, which eliminate the blast wheel idling and injuring workers.

3. The machine adopt environment friendly high efficiency cartridge filter, dust collecting efficiency reach to 99.9%

4. The machine with limit switch on access door, that protect people in any case they open the door, the blast turbines will stop according.

5. Six layers protection curtain for protection the shot balls spatter out during blasting.

6. The machine with sand-guide channel at the outlet of the equipment, and the steel shot on the steel structure can be poured out in the sand-guide channel, and then enter the recovery system.

7. The steel structure shot blasting machine use high effective abrasive recovery system. A longitudinal screw conveyor to reclaim the used blasting media and contaminants into the crosswise screw conveyor, then into the bucket elevator and abrasive residue separator, and then the cleaned abrasive get into the storage hopper to recycle, the residual will get out of the recycle system from the air wash cleaner system.

 Abrasive residue separator

Our patented abrasive cleaner is applied for recycling shot/grit, which is to ensures high quality blasted surface and minimal abrasive shot. As the abrasive is so durable it is able to be recycled hundreds of times, resulting in an extremely low abrasive breakdown rate.

Critical to achieving this efficiency is the effectiveness of the abrasive recycling plant. Poorly designed or manufactured abrasive recycling systems will not correctly recycle the abrasive and are unable to maintain the correct abrasive working mix.

Our patented abrasive separator consists of an extended rotary separator drum that will totally remove all big clumps including big wast, scrap and paint chips etc. The abrasive is then fed through a gravity air wash separator where all dust, degraded abrasive and waste is drawn out of the good abrasive by an air current.

Only good, correctly sized abrasive is fed back to the abrasive storage hopper and blast pots for recycling.

Our patented abrasive cleaner ensures maximum recyling rates of the abrasive and high quality surface finishing is achieved.
