1. A method for making reconstituted limestone blocks, the method comprising:
using a batching plant to make a limestone mixture, wherein the batching plant has been modified to be compatible with the limestone mixture, and wherein the batching plant has a volume sufficient for making enough of the limestone mixture to produce reconstituted limestone blocks each having a weight of 200-1200 pounds at a rate of 100 reconstituted limestone blocks per hour;
transferring the limestone mixture from the batching plant to a mobile stamping machine having a mold box, a hopper, and a feed apparatus configured for transferring the limestone mixture from the hopper to the mold box;
activating the mobile stamping machine so that the mobile stamping machine forms a reconstituted limestone block by transferring the limestone mixture from the hopper to the mold box, depositing the reconstituted limestone block out of the mold box, and then moving to a next location, wherein the mobile stamping machine is configured to produce reconstituted limestone blocks each having a weight of 200-1200 pounds; and
generating a plurality of reconstituted limestone blocks using the activated mobile stamping machine at a rate of approximately 100 reconstituted limestone blocks per hour or more,
wherein making the limestone mixture comprises mixing crushed limestone, cement, water, and a plasticizer, and
wherein the crushed limestone comprises 80%-93% of the limestone mixture on a dry ingredient basis.
