Sand producing method and apparatus. |
摘要 |
<p>A screen is disposed between different two types of crusher such as a centrifugal crusher and a vibration mill.
<??>Respective passage weights and fines modulus of the stone crushed by the centrifugal crusher and the crushed stone having sizes greater than meshes of the screen and a fines modulus of sand to be the final product are measured and are inputted into a control board having a computer, thereby controlling the amount of the stone fed to the screen and a rotational speed of the vibration mill. Thus, sand having a desired granular size may be produced at low cost. </p> |
