Fine aggregate Sand Equivalent Tester

Product ID:HW-SYD-0334

The instrument is designed and made as per T0334 “Fine Aggregate Sand Equivalent Test” in the Industry Standard JTJ 058 Specification and Test Methods of Aggregate for Highway Engineering.  The instrument vibrates sample using an automatic vibrator to let sample cylinder move transversely along a straight line.  It is suitable to determine clay or impurities in the fine aggregates, so that to evaluate purity of aggregates.  The sand equivalent is indicated by SE.  The instrument is suitable for determining natural sand, artificial sand, and saltpeter used in bituminous mixture and cement concrete.  Their maximum aggregate size should be more than 4. 75 mm (round-hole sieve of 5 mm).

 

Features

1. Double-tube working mode, parallel automatic oscillation of two samples at the same time, convenient operation, good oscillation effect and high work efficiency.

2. Desktop structure, the number of oscillations and oscillation time are displayed by the digital tube. After the sample is installed, it can automatically complete a cycle of oscillation.
