problems concerning premature sand clogging and failures with ASTM C-33 sand as the filter media, revisions were made to the Recommended Standards and Guidance (RS&G) for Intermittent Sand filters in 2000. The revised RS&G began to allow the use of a coarser sand media specification that is more clog-resistant than the ASTM C-33 sand specification.
Water Treatment Silica Sand is manufactured under high quality control monitoring program extracted from high purity quartz silica sand mines reaching to our factories located in Saudi Arabia for minerals treatment processes which includes washing, drying and grading to meet the strengths specifications standard of ANSI/AWWA B100-09 as per ASTM E11 Test sieve standards.
Test parameters can be altered with Taber's Oscillating Sand Abrasion Tester, and allow the operator to select the operating stroke length (6.5 to 150 mm) and speed (variable from 100 - 200 cycles per minute). ASTM F735 specifies the sand tray travels a distance of 100mm at a speed of 300 strokes per minute (150 cycles per minute).

TE 65 MULTIPLEX SAND/WHEEL ABRASION TESTER Background Abrasive wear of industrial materials handling plant (e.g. transfer chutes, conveyors and hoppers) is a direct cause of repair, replacement and downtime and represents a major factor in the cost of production.
Spent foundry sand consists primarily of silica sand, coated with a thin film of burnt carbon, residual binder (bentonite, sea coal, resins) and dust. Table 7-2 lists the chemical composition of a typical sample of spent foundry sand as determined by x-ray fluorescence. Silica sand is hydrophilic and consequently attracts water to its surface.
