Brief introduction The instrument by automatic mechanical vibration, the sample cylinder make lateral oscillation sample linear motion way, is suitable for the determination of fine aggregate in the cohesive soil or the content of impurities, to assess the cleanliness of aggregate, sand equivalent to SE said. This instrument is suitable for the determination of natural sand, artificial sand, stones etc. Various kinds of fine aggregate nitrate content of cohesive soil or the content of impurities, nominal maximum size is less than 4.75 mm. Features 1. This instrument is a double tube works, automatic oscillation can be parallel for the two sample, easy to operate, oscillation effect is good, high work efficiency. 2. The instrument for desktop structure, oscillation frequency and oscillation time by the digital tube display, can automatically complete a sample after packed the oscillation cycle.
