- Synopsis:
- This study relates to the development of a manufacturing machine of artificial coarse aggregate which excels in grain shape and grading. The experimental results of coarse aggregate produced by the kinetic energy of many chain rotating at high speed in the presented stone crusher are reported. In this investigation, a total of 24 specimens are made for three kinds of stones which used now for raw stones in our country, and the grain shape and grading of produced coarse aggregate are examined. The results show that the presented stone crusher can produce coarse aggregate with excellent grain shape and grading.
