Description

Most suitable machine for abrasive materials

The W.S. TYLER® Ro-Tap® RX-29  for test sieves up to 203 mm diameter reproduces the circular and tapping motion of hand sieving but with an even mechanical action. .

  • The safety cupboard meets the demands of job safety that are necessary for CE-labelling in Europe.
  • Enables sieving of agglomerating bulk materials.
  •  Prescribed in the FEPA-standard for abrasive industry.

Applications

  • Diamonds
  • Abrasives
  • Shot Media
  • Sand & Gravel
  • Pharmaceuticles
  • Minerals and Ores
  • Refractories
  • Granualates and Pellets
  • Recycling

Further advantages 

  • The 3D sieving action saves time and manual re-sieving.
  • Easy handling – only sieving time has to be set.

If a particular size media is specified for your grit-blasting process, how can you determine if a shipment of brand new abrasive blasting grit is sized correctly for the work? What does the number mean in an abrasive grain designation, such as #80 aluminium oxide?

Grit sizing specifications are based on the agreed-upon particle size distribution for each screen or mesh size. Certified or Inspection Test Sieves each bear a number that corresponds to a size in the Standard Sieve Series with mesh or screen openings as specified.

Lower sieve size numbers mean coarser abrasive particles, and higher numbers designate finer grit.

According to ANSI B74.12-2001, for #80 grit abrasive, the following particle size distribution conforms to the standard:

  • 100% pass through Sieve #50
  • 25% maximum retained on Sieve #70
  • 40% minimum retained on Sieve #80
  • 65% minimum retained on Sieve #80 + Sieve #100
  • 3% maximum pass through Sieve #120

The Operating Media Mix

It is normal for a few media particles to fracture during blasting. Excessively high blast pressures increase the attrition rate, but in a cabinet-blast machine that reclaims and recirculates the media, it is predictable that the percentage of fractional particles (fractured one or more times) will gradually increase, and the number of full size particles will gradually decrease, unless new grit is added.

For general cleaning applications, such as rust and paint removal, if the results are judged by visual inspection and no particular surface texture or roughness needs to be produced, there is no obvious problem if the operating mix of media particle sizes includes mostly finer grit. Fracture of media particles might be seen as a good thing, since it produces sharp new cutting edges. An excessive percentage of fractional media particles might not be noticed until it takes a lot longer than usual to get the blasting done, or until dusty operation makes visibility difficult inside the blast cabinet.
