Sandstone is made of compressed particles of silica, the mineral that makes up sand. When sand is piled on top itself over time, with a considerable amount of weight, this sedimentary rock is formed.
To do this you will would normally use a large wire filter where holes are set at about the size of sand. By vibrating this net area it sifts out the sand leaving rocks in the netting - It can be undertaken by multiple operations where holes in the netting become smaller so filtering page to small grains/rock. A crude method is using a rake to drag away large rocks from sand
