SKRR-4數顯軟弱顆粒測定儀

一、適用范圍：

測定碎石、礫石及破碎礫石中軟弱顆粒含量。按顆粒大小分別加以0.15kN、0.25kN、0.34kN之荷載，破裂之顆粒即屬于軟弱顆粒，將其棄去，稱出未破裂顆粒的質量。

1. Scope of application:

Determine the content of soft particles in crushed stone, gravel and broken gravel. Loads of 0.15kN, 0.25kN, and 0.34kN are applied according to the particle size. The broken particles are weak particles. Discard them and weigh the mass of the unbroken particles.
