The present invention is related to fabrication of unique tapered horizontal leather belt roller for dal milling devices. The invention discloses the different units of the unique roller fabricated and the process for its fabrication including spacing and tapered placement of rasp bars and fastening of leather belt pieces on rasp bars in zigzag manner besides the horizontal orientation of roller. The leather belt pieces fastened on rasp bars exerts the rubbing action against the perforated screen so as to reduce down the impurities into smaller particles and rain affected grains into splits and separation thereof from good grain mass.
