This study wasdone to assess the effect of using combination of abrasive roller assembly for pulse milling and to reduce losses to minimum by improving dal recovery and efficiency of machine. Different grade combination Le. (8,16,24), (16,24,32) and (24,32,40) of abrasive roller assembly was fabricated, fitted in CIAE Dal mill and milling experiments for pigeon pea, chickpea and green gram using different pre milling treatments such as conventional, CIAE and Millers practice method was carried out. The moisture content of raw pulse was in the range of 10–14%. During conventional, CIAE and millers practice method of pre milling treatments the moisture content reached up to 55–58%, 46–53% and 35–40% (wb), respectively, but during milling it was maintained at 9–10%(db). The maximum dal recovery of 74.40% was inthecase of millers, practice method using combination of 16, 24, 32 grades of abrasive roller assembly for pigeon pea and 75.50% with 8, 16.24 grades for chickpea and 73.40% with 24, 32, 40 grades for green gram. The maximum milling efficiency of 82% was obtained using combination of 16, 24, 32 grades of abrasive roller assembly for pigeon pea.
