Abrasive media for grit blasting

Abrasive grit blasting machine, also known as sand blasting, is a surface treatment process that is widely used in a wide range of industries for a variety of purposes. Abrasive blasting is the process of accelerating abrasive media through a sand blasting nozzle using compressed air. The abrasive used depends on the surface treatment needed. Abrasives media that are commonly used for grit blasting:

  •  Steel shot
  •   Steel grit
  •  Glass bead
  •  Crushed glass
  •  Aluminum oxide
  •  Silicon carbide
  •  Plastic abrasive
  •  Walnut shell
  •  Ceramic grit
  •  Copper slag

Contingent upon the application, there is a horde of abrasives accessible to browse. With more than 30 years of 'in the field' insight, Steel shot supplier use four fundamental sorts to address 99% of our customers' issues and, whenever required, are glad to utilize other blasting media, for example, Steel Shot and Grit, Stone Grit, Crushed Glass, Walnut Shells, Bicarbonate of Soda and Sponge – however, for the time being, we'll adhere to the primary these are following:

Garnet sand

A normally happening type of aluminum oxide is orchestrated in the almandine structure. Abrasive Garnet Sand is by and large viewed as a nonessential single-utilize abrasive with a semi-precise structure, accessible in various estimating grades – reliant on the completion required – and gives incredible cleaning results and is the abrasive of the decision here at Steel shot Supplier.

Aluminum Oxide

High-grade alumina produced from bauxite, silica, coke, and iron having an uncommon hardness, high recyclability, and generally utilized on non-ferrous things in order to evade impingement or cross-tainting, accessible in contrasting estimating grades. Steel shot provider uses brown Aluminum Oxide Abrasive in many contrasting applications, including the modern shoot cleaning of steam turbine segments for NDT/NDE.

Glass Bead 

A high evaluation made soda-lime delivering close to entirely adjust particles which, when utilized in impacting procedures, grant a cleaned or shine finish to the surface, again accessible in shifting measuring grades. Steel shot supplier embraces glass beads – where determined by the end-client – in the industrial blast cleaning of gas turbine parts for NDT/NDE.

Chilled Iron 

A recast intertwined iron abrasive with intense, forceful properties and a high recyclability rate when utilized on ferrous things, generally accessible in a huge scope of estimated grades. Chilled Iron is essential to take note that if the thing being dealt with is non-ferrous and getting an ensuing covering, coating, or painting, an option reasonable abrasives ought to be looked for.

Plastic Abrasive

Plastic abrasives are dry thermoset cleaning media composed of crushed urea, polyester, or acrylic. Each differs and is available in a variety of hardness and particle size. Plastic abrasive media is widely regarded as the best media for mould cleaning, blasting of plastic parts, and applications where substrate material removal is not permitted. Automotive, aviation, boating, electronics, and industrial applications are all common industries.

Silicon Carbide

Silicon Carbide is the hardest abrasive blasting material available, making it the best choice for your most difficult surface finishing applications. It comes in a variety of colors and purities. Its primary applications include bonded abrasive tools, lapping, polishing, glass etching, and general-purpose heavy-duty blast cutting.

Steel Shot & Grit

Due to its toughness and high recyclability, steel abrasive is a cost-effective alternative to other abrasives. Steel shot & grit can be used to effectively remove contaminants from a variety of surfaces, texture a surface for proper adherence of a final coating, or in peening (hardening) applications. The proper size, hardness, and shape all play important roles in media selection.

The choice of media is an important consideration in the design of abrasive blasting processes. The various media types differ in hardness, shape, and density, and each is available in a variety of particle sizes. Many times, sample processing is required in order to lock in the final media type and size. Sand blasting equipment varies by industry; there are hand cabinets, dedicated automatic high production models, and completely robotic systems with closed loop process controls. The machine used is determined by the surface treatment used as well as the end use of the component.
