abrasive wear test machine in laos

The Los Angeles Abrasion test also known as the LA Abrasion test for short is widely used as an indicator of aggregate quality The test measures the degradation of standard gradings of aggregates subjected to abrasion and impact in a rotating steel drum containing an abrasive charge of steel balls

Procedure of the LA Abrasion Test Prepared sample is placed in the abrasiontesting machine A specified number of steel spheres are then placed in the machine and the drum is rotated for 500 revolutions at a speed of 30 33 revolutions per minute RPM

Feb 22 2010 · Los Angeles abrasion test on aggregates is the measure of aggregate toughness and abrasion resistance such as crushing degradation and disintegration This test is carried out by AASHTO T 96 or ASTM C 131 Resistance to Degradation of SmallSize Coarse Aggregate by Abrasion and Impact in the Los Angeles Machine The aggregate used in surface course

Universal Wear Tester to determine the wear and abrasion resistance of fabric used in clothing footwear and industries This Wear Testing Machine complies with ASTM D3514D3885D3886 AATCC 119120 FTMS 19153005302 etc

General description This machine has been developed for determining the resistance to abrasionwear of natural stones and concrete products Easy to use electronic control of the disc speed with auto shutoff of the machine at the selected number of revolutions The abrasion disk wheel is 70 mm thick

Application DIN Abrader abraser is suitable for the abrasion resistance test of polyester sole shoe sole and polymer sheet material When the wear wheel rotates the sample is rubbed in a certain degree of sandpaper to generate abrasion so as to evaluate the wear performance
