It is fact that in ancient era people had invented a stone mill for grinding pulses, grains etc. I have seen stone mill in my village 2 decades ago. It was a useful tools to grind many eatable seeds. However diesel mill and electric mill has vanished it now. However some people are still using this equipment to grind pulses at home also if mill is far away from her house. After long time i saw this equipment once again in a relative house two days ago and i captured it in my Smartphone.
User of stone mill puts pulses or grains in lower part of stone then upper part grind it when people rolling it by hand slowly. It is laborious job in fact. Maximum ancient farmer had this equipment in their home at least one. However above stone mill is modern manufacturing and small in size but i have searched its original shape by the help of google and that is just below :
Above is enough to describe all.
