一、引言对磨粒强度的测定,现在国内仍普遍采用静压法。用辊碎法测磨粒的强度,是1974年由美国的J.N·Brecker等人提出的,我们认为该方法使磨粒受挤压力破碎的随机性好,磨粒的破碎过程接近于磨削。为此,我所于1980年研制成了一台简易式的辊碎法测定单颗磨粒强度的装置,图1为该装置的简图。

First, the introduction of the determination of abrasive strength, and now still commonly used static pressure method. By roller crushing method to measure the strength of the abrasive grain was proposed by JN Brecker et al. In the United States in 1974. We think this method makes the crushing force of the crushed granule to be crushed with good randomness and the crushing process of the abrasive grain is close to grinding . To this end, I in 1980 developed a simple roll crushing method for determining the strength of a single abrasive device, Figure 1 is a simplified diagram of the device.
