Regrading capacity: The Brilliant Sponge Regrader delivers up to 600 kg per hour of high-quality, regraded sponge media.
The Brilliant Sponge Regrader is specifically designed to regrade various grades of abrasive sponge media.
The Brilliant Sponge Regrader is fitted with a 3-level filtering system: large debris, reusable sponge, and fine dust.
- The large debris and fine dust will be disposed of.
- Large debris grid has an aperture of approximately 9-10 mm, The dust sieve has an aperture of 2-2,5 mm.
The Brilliant Sponge Re-grader has a proven feeding action of sponge media, and the sponge does not flow over intermittent levels of the re-grader.
– The sponge media pass over a distance of at least 10 cm of vibrating grid before being fed out of the exit chute of the re-grader. This delivers a high quality re-graded sponge media.
Electrical specifications: The sponge regrader operates with a 0,18 kW (220-240 V – 50 Hz) electrical vibrating motor.
- Centrifugal force kN – 2.07
- Centrifugal force kg – 211
- Closing force kg – 193
All Brilliant Sponge Regrader machines are designed and fitted with front and rear wheels to make them mobile and easy to move around working areas
Sponge Blasting
What Is Sponge Blasting?
How Does Sponge Blasting Work?
- Compressed air propels sponge media to the surface.
- Upon impact, sponge media absorbs collision energy and flattens on the surface. When the abrasive aluminium oxide is exposed to the surface, the contaminants are removed. The coating is removed, leaving the required profile on the substrate.
- The sponge media entraps most airborne dust.
- Sponge media contains different sizes and grades of abrasives for use on various surfaces.
- Dry Ice International’s professional blasting technicians will carefully select the best sponge media to comply with client–specific requirements.
- Air requirements: 11.35 m3/minute (400 cubic feet per minute) at 7 bar (100 psi).

Industrial Painting
What Is Industrial Painting?
Dry Ice International has provided award-winning solutions streamlining the dry ice industry. Dry Ice International is the market leader in dry ice products and dry ice blasting solutions in South Africa. According to a recent market survey, the proven capabilities and scale of our production solutions, support operations and reliability have positioned Dry Ice International for continued success in the future.
It’s the application of surface covering: preserving, protecting and functionally enhancing untreated and treated surfaces and structures including all required pretreatments. Industrial paint has two purposes:
- Provides a protective coating against chemical and physical attack
- Gives the product a pleasant appearance that increases its value
Industrial painting considerably extends the life of objects and buildings. It contributes to the reliability, safety and availability of the painted surface and serves sustainability and the environment in general. Preparation is usually the key to long lasting applications. The process tends to be easier if paint was not applied previously, otherwise a removal of the existing coat is required, making use of sand, sponge or dry ice blasting.
Industrial paint can be used to protect metal, wood, and a variety of other materials and surfaces. Various characteristics depend on the ingredients of the paint and the performance specifications of the selected application. Application methods can also influence the quality of the paint coverage and determine how well paint will stick to the surface.
How Does Industrial Painting Work?
Industrial paint can be applied to various structures that can be aggressively cleaned. It is essential to blast before painting, because the removal of all rust is of supreme importance in providing a long-term corrosion resistance system.
Various paint systems may be used, including inorganic and organic zinc-rich primers and zinc phosphates, epoxies, epoxy tars, alkyds, acrylics, vinyl, enamels and polyurethanes.
Painting is done under cover to ensure that the blasted surface does not rust before painting. Blasted surfaces can begin to rust or become contaminated within 4 hours.
When surface preparation and painting is done outside, the clean steel starts to rust immediately, especially if humidity levels are high.
Therefore painting needs to be done immediately after surface preparation in order for it to be successful and long lasting.
The overall quality of painting under cover is better due to less interference from the wind, dust, rain and general contamination from the environment. This ensures that the required thickness is accomplished within the necessary time span and that the paint dries without accumulation of dirt and dust in the coating.
