A small hammer or impact mill is used to further reduce the ore size after the jaw crusher. From 1/4 or 1/8 in. down to 50 or 100 mesh size. Small impact mills are fairly inexpensive, 1,000 to 1,500 for a good quality unit that can process 100 pounds or more an hour. They are also fairly small and portable.
