The history and processes of milling resilience

These roller mills are able to process a large quantity of grain, so rather than bringing grain to local stone mills, significant quantities of grain were transported to centralized roller mills. This meant that along with the loss of nutrition when the new system was introduced, there was also a loss of smallscale milling on the community level.
