SKRR-4数显软弱颗粒测定仪

一、适用范围：

测定碎石、砾石及破碎砾石中软弱颗粒含量。按颗粒大小分别加以0.15kN、0.25kN、0.34kN之荷载，破裂之颗粒即属于软弱颗粒，将其弃去，称出未破裂颗粒的质量。

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.
