Concrete is the most popular material in infrastructure facilities’ construction.
Next the falling particles will be well shaped by jostling each other and collision with throwing material hammer when they are passing throw the narrow zone between the throwing material hammer and the rock bed.
On the other hand, the radius size of particles and the interval between the rock bed and the throwing material hammer might also affect the sand production.
