Sand blasting:
12-24 Mesh:
The larger / coarser garnet sand abrasive grains are mainly used for sand blasting , remove the thickest coatings and surface treatment before coating in ship repair,shipbuilding ,industrial painting ,steel structure,aluminum,rubber,and bridge etc.
20-40 Mesh:
The medium / intermediate garnet sand abrasive grain used for faster removal of harder surfaces where speed is important or there are thicker layers of paint or rust.
30-60 Mesh:
The finer / smaller garnet sand 30/60 mesh is most popular and widely used grade(size),the fast speed blast efficiency on thickest coating removal, ship cleaning,machinery maintenance , heavy equipment repair, paint & rust removal prior to painting and surface preparation in painting industries, tarnish cleaning etc.,
Water jet cutting:
60 Mesh:
The garnet 60 mesh is medium particle size for high speed water jet cutting,it can deliver up to a 30% increase in cutting speed at reduced precision edge, used to cut thick stainless steel, titanium and stone,etc;
80 Mesh:
The garnet 80 mesh is most popular and highly versatile size used for water jet cutting,it is medium to fine particle size for faster and smoother cutting,can presenting good edge finish as well as achieve the supreme speed,mainly used to cutting tiles, Kevlar, marble ,granite , stone , stainless steel , copper,steel plate , glass ,aluminum alloy, and other precious metal,etc;
120 Mesh:
The garnet 120 mesh is fine particle size,mainly used to cutting high precision material with outstanding edge quality ,like glass , precision metal,ceramics, laminates, composites and other brittle materials,etc;
Water Filtration:
The ZW Garnet sand has features of heavy specific weight ,stable chemical properties,no free silica,It is harmless to the environment and humans, which can meet the requirements of occupational health and safety,so can used in a variety of filtration applications which include Industrial Waste Water treatment and commercial water filtration.The garnet sand is possibly the most cost effective alternative for water filtration beds as it resets the filter bed more rapidly after the bed is back-flushed. Moreover, it is also effective for the elimination of heavy minerals.
The garnet 12/24 mesh,20/40 mesh is suitable size for water filtration.
