Crushing Stone

In the early 1900s, after the Banning quarry ran out of high quality stone, it turned to manufacturing crushed stone to stay in business. Rocks were dumped down from the railroad track and loaded by hand into the crusher. From under the crusher, a bucket conveyor carried the stone to sorting screens and bins built high above concrete walls. After screening and sorting by size into storage bins, the stone could be emptied into a rail car waiting below.
