Aluminium Silicate 70 mesh

Understanding Aluminium Silicate 70 Mesh for Blasting

Aluminium Silicate 70 mesh is a synthetically produced mineral abrasive. The controlled manufacturing process yields a consistent particle size distribution and angular grain shape, which translates to uniform cleaning rates and repeatable surface profiles. The 70 mesh designation indicates a medium-fine grit size, making it suitable for applications where a moderate anchor profile is required before coating or lining.

Unlike some mineral abrasives, this synthetic silicate is formulated with low free-silica content, addressing occupational health considerations in enclosed blasting and high-consumption environments. It generates less dust compared to traditional expendable minerals, improving visibility during blasting and reducing cleanup time.

Typical Industrial Applications

This 70 mesh abrasive serves multiple surface preparation functions across industries. It is frequently specified for removing mill scale, rust, and old coatings from structural steel, storage tanks, and fabricated components. Foundries use it for cleaning castings and removing sand residues. Maintenance teams rely on it for refurbishing process equipment, piping, and machinery surfaces prior to repainting or applying protective coatings.

The medium-fine particle size also makes it a candidate for surface finishing on non-ferrous metals and composites where a controlled, shallow profile is desired. It can be deployed in both suction-fed and pressure-fed blast systems, as well as centrifugal wheel blast machines.

Selection and Handling Guidance

Selecting the correct mesh size depends on your target surface profile, substrate material, and blasting equipment configuration. The 70 mesh grade provides a finer finish compared to coarser 30/60 mesh options, making it suitable for thin substrates or applications requiring a smoother surface before painting. Always verify compatibility with your blast nozzle size and air pressure settings to achieve optimal consumption rates.

Store this abrasive in a dry, covered area to prevent moisture absorption, which can cause clumping and inconsistent flow through metering valves. When transferring from bulk totes to blast pots, use proper dust extraction to maintain a clean working environment. SPA2Z can advise on pack size selection based on your monthly consumption and storage capacity.
