When we make sand, the third generation sand making machinery and the rod mill are main equipment, but we can also see the situation of the over-broken. Today, the exports in Hongxing will explain it to you.
Firstly, when the rock was sent into the rod mill, we should discharge it timely after broken. If it was grinded too long, it will be over-broken.
Secondly, the gap between the sticks are the way to protect the rock from being over- broken, if the gap between the sticks are too narrow, the sand will be over-broken.
Lastly, the compression strength of the rock is weaker than the stick. So the sand was easier to be over-Broken.
