A powered roller conveyor moves steel material through a blasting machine available in many sizes and configurations for common I-beams, steel plate, angles, pipe and fabricated structures.
The operation costs are very low compared to the costs of manual air nozzle blasting. It is an economical method of surface preparation before coating works.

Some people called it a ‘turbine’ which does not describe it correctly.
Large Spiral Pipe Manufacturing Plant

The external surface blasting machine and the surface after blasting; no worry about the rotated marked lines left by the rollers, the finished profile is achieved.

Internal pipe blasting requires the same blast wheel to do the job in order to match near the speed of in line production works. Shown above right is a test piece result.

Concrete surface and steel floor shot blasting machine is a cost-effective and environment friendly method for preparing concrete and steel surfaces. It is widely used for its easy operation and high productivity. The shot blasting machine leaves the surface immediately ready for application of coatings.

PRESSURE APPLICATIONS OF ROOTS BLOWERS
There are many industrial pressure roots blower applications, from assisting in combustion by pumping air or gas into burners, furnaces and forges to pressurizing paper mill head boxes. The following are some major areas of application: Combustion, Drying & dehydration, Aerating & Agitating liquid, Pneumatic conveying.

VACUUM APPLICATIONS OF ROOTS BLOWERS
Roots blowers are frequently used as vacuum pumps. As a result, industrial vacuum roots blower applications are widespread and include the following:
Vacuum:-9.8กซ-50kPa Suction Flow:0.52 กซ183.9m3/min

VS250-55 | 64 | 39 |
VS250-75 | 61 | 44 |
VS250-90 | 71 | 49 |
Vacuum Recovery 22-30kw – Used for Suction of Dust on the raw material after blasting works.
Vacuum Recovery 30-55kW - Used for vacuum blasting in combination with blast pots.

The vacuum unit assembly puts in action with options to include larger storage silo, continuous auto-dumping, abrasive separation and stream line charging to blast pot machines.
Generally, the system is made up of an enclosure steel frame, vacuum pump, motor and cyclone type dust collector with sensor, cartridge type dust collector, exhaust silencer and control panel with the necessary gauges.
Garnet Recovery Dryer Separation Equipment
The Open University
Generally, one can expect a 20-25% breakdown rate at 90-110 psi at the nozzle with garnet sand of 30/60 size.
The recycled abrasive should be checked to ensure that the separation unit is removing both oversized coarse contaminants (typically 20 mesh or larger) and fines (typically 80-90 mesh or smaller). The abrasive discharged from the air-wash separator (into the trash/dust bin) should also be checked to determine if usable abrasive is being improperly withdrawn from the working mix.
The most accurate way to determine the exact distribution of the working mix of the abrasive particles is to conduct a sieve analysis. Complete instructions and procedures on the use of test sieves are contained in ASTM STP 447, Manual on Test Sieving Methods. For a detailed sieve analysis, use #20, #30, #40, #50, #60, #70, #80, #90, #100 and #120 mesh USA Standard Sieve screens. A full set of screens is invaluable for monitoring the particle size distribution of the working mix.
A short-cut method used to reduce the complexity of conducting a complete sieve analysis is to select the “critical” screen for the blasting application where recycled garnet is being used. For example, to check for excessive fines in the working mix, use a single #80 or #100 mesh screen. To check for too much usable garnet being extracted by the air-wash separator, use a single #60 mesh screen. This will give a relative indication of how well the recycling process is being managed and identify any potential problems.

WEBLAST has practical experience with recycling in blast rooms and on field projects. We are familiar with a variety of designs for recycling equipment, as well as abrasive handling and flow issues encountered during recycling.

Specialized 3LPP Blasting & Coating Facility
How it is done


on straight pipe & on long radius pipe elbow
This special structure protects the material from a number of conditions and materials. The 3lpp pipeline coating is excellent in preventing the steel pipes from being in contact with corrosive chemicals and agents. Also the coating prevents the material from coming into contact with any hard surface directly and prevents physical damage as well.
The 3lpp coated pipe can come in different specifications such as DIN 30670, CSA Z245.21, AS 4321 and IS 3581. The coating is also resistant to cathodic disbondment, meaning the coating is not affected by electric charge which can damage most other types of coatings. The 3lpp pipe can last longer and has higher performance compared to non – coated or other types of coatings. The application of this special coating is mostly in the oil fields which operate under high temperatures. The Three Layer Polypropylene Coated Pipe can be used in abrasion prone applications such as drilling operations and in rocky surface applications.
WEBLAST design and fabricate facility for 3LPP coating of long radius pipe elbow, specifically for a national petroleum piping plant in an Asean country.

Hang up the work piece and convey it in through a blast room, oven chamber and a powder spray booth.

Design sized to meet your specific required air flow capacity.

Centrifugal type wheel that does the propelling of abrasive at a continuous high speed stream of shots hitting the material surface resulting in surface cleaning, was invented in the early years of 1900.

Each blast wheel cleaning capacity is defined by its related horsepower rating. WEBLAST can supply the full range that might be needed for a job. Generally, we recommend the sizes below:
HP | 5.5 | 10 | 15 | 20 | 25 | 30 | 50 |
Kw | 4 | 7.5 | 11 | 15 | 18.5 | 22.5 | 37.5 |
Buying Parts for DIY Projects
We show you a partial list of items needed for your DIY projects here.
Blast Pots & Related Parts
The most productive combination of parts for a blast pot assembly allows for shut-off of compressed air and abrasive grits separately. A handy radio signal button switches control such,
Button Combination | Air Valve | Grit Valve |
0 0 1 0 1 1 |
Off On On |
Off Off On |
This allows full control by the blaster himself without assistance from others to begin the air line, turn on the grit valve, shutting off the grit valve only & finally shut off the air supply.
Wet Blast Cleaning
Do you have soiled & dirty equipment such as an excavator or truck that requires old paint removal for recoating works?

We can provide non-destructive dust free wet blast reconditioning equipment for such cleaning purposes.
