Abstract
This study is concerned with the development of a new manufacturing machine of concrete aggregate which excels in grain shape and grading. We report the experimental results of concrete aggregate treated by the kinetic energy of many chains rotating at high speed in the presented stone crusher. In this investigation, many experiments of crushing treatment were carried out for some row stones, and the grain shape and grading of produced concrete aggregate were examined. The experimental factors were size and rotation speed of chain. The test results showed that the presented stone crusher could produce concrete aggregate with excellent grain shape and grading.
