Garnet Abrasive for Sand Blasting Machine 

Our natural garnet abrasive is professional blasting media specially matched for all types of sand blasting machines. Low free silica, low dust, recyclable, high cutting efficiency, widely used for metal rust removal, oxide layer cleaning, surface texturing, glass carving and ship hull treatment. Multiple mesh sizes in stock, stable supply, factory wholesale, support OEM package.

Product Overview

Garnet abrasive, also called garnet blasting grit, is eco-friendly natural mineral abrasive exclusively designed for sand blasting machines, pressure blasting cabinets, automatic roller blasting equipment and large open-air blasting systems.

It is extracted from high-purity almandine garnet ore, processed through crushing, washing, magnetic separation and grading. Compared with silica sand and cheap slag abrasives, garnet features zero free silica, low dust, high hardness and sharp cutting edges, becoming the most popular blasting media for global surface treatment factories.

Key Physical Parameters

• Mohs Hardness: 7.0–7.5, strong cutting force, fast descaling & derusting

• Free Silica Content: 0%, meets international environmental safety standards

• Density: 3.9–4.1 g/cm³, good fluidity inside sand blasting machine pipelines

• Available Mesh Sizes: 30# / 60# / 80# / 100# / 120# / 180# / 240#

• Shape: Sharp angular crystal, excellent surface etching effect

• Recyclable Times: 3–5 times, lower comprehensive blasting cost

Core Advantages For Sand Blasting Machine Users

1. Safe & Environment Friendly

No free silicon dioxide, no toxic dust, effectively avoid silicosis risk for workers; greatly reduce workshop dust pollution, fit closed cycle sand blasting equipment.

2. High Blasting Efficiency

Sharp angular grains quickly remove rust, paint, scale, oxidation film without damaging base metal; shorten working time, save air compressor power consumption.

3. Long Service Life & Recyclable

Hard and wear-resistant, not easy to break into ultra-fine powder during blasting. Can be recycled multiple times in cyclone separation sand blasting machines to cut material cost.

4. No Secondary Contamination

Low iron content, will not leave iron stains on aluminum, stainless steel, copper alloy workpieces; ideal for precision metal surface treatment.

5. Smooth Machine Operation

Good fluidity, not easy to block gun nozzle and conveying pipeline of sand blasting machine, reduce equipment maintenance frequency.

6. Complete Specifications In Stock

Full range mesh sizes for fine polishing to heavy rust removal, support mixed size customization according to customer blasting process requirements.

Wide Application Scenarios

Perfect matching all manual, automatic, cabinet type and large tunnel sand blasting machines:

• Metal industry: Steel plate rust removal, stainless steel matte finishing, aluminum alloy deburring

• Ship & container: Hull surface cleaning, anti-corrosion pretreatment

• Glass processing: Glass carving, frosting, decorative glass surface blasting
