A natural conflict resulted between the millstone and the wheat roller mill, there was also a conflict between the water wheel and the turbine. Many millers held a belief that the water wheel was superior to the turbine. There were arguments as to which system would work better together, the millstone or roller mill.

When millstone grinding began to be threatened by the roller mills, the miller tried to improve the dressing of the millstone. The wheat roller mill became a good alternative to the progressive millers who wanted a better milling process. They wanted to improve the quality and quantity of their flour product. This led to the primary attraction of the use of roller mills. In replacing the millstone with roller mills, the miller gave up the time consuming process of dressing millstones. The early WHEAT ROLLER MILL could not do as well of a job in flouring middlings as millstones. It was not until roller mills were improved that their use grew. The first use of roller mills was to break up the grain. Then a pair of millstones would be used to regrind the particles into flour. Eventually this practice became obsolete with the addition of other rollers replacing the millstones. The miller had to learn new skills. He learned that by increasing the number of breaks he could extract almost all the bran and produce superfine white flour.

In the larger milling operations they started to bleach the white flour. It was soon determined that any remaining particles of bran and germ were made more noticeable. This process of wheat roller mill produces break flour mixed with bran. Increasing the number of breaks and bolts, the total extraction of flour would remain the same as from millstones. The use of gradual reduction with rollers, the percentage of best-grade flours could be increased, while the poor-grade flour would remain the same or be reduced.
