Energy Efficiency of Brazilian Hammer Mills Grinding Maize

The hammer mills to be tested are driven by an asynchronous motor (3.75 kW; 3515 rpm) via an rpm-torque measuring shaft mounted on a separate stand. By ex-changing the V-belt disc at the input and the output of the measuring shaft, the rpm of the hammer mill is altered in 5 steps.AIt is generally believed that roller mills utilize energy more efficiently than hammer mills (Silver, 1931; Puckett and Daum, 1968; Appel, 1987). To verify this, a completely randomized factorial experimental design (CRD) with two replications was constructed: a total of 72 grinding tests was conducted to compare the energy efficiency between a roller mill and a hammer mill.COMPARISON OF ENERGY EFFICIENCY BETWEEN A ROLLERmer mills), hammer mills have the widest application due to their grinding efficiency, as described by Bochat and Wesołowski (2009, 2010b), Dmitrewski (1992), Kapur etA.
