FIELD: process engineering.
SUBSTANCE: invention relates to crushing devices and can be used in cereal-processing industry, food industry, etc. Roller mill comprises drive articulated with rollers arranged to displace horizontally and vertically relative to each other and with adjustable clearance, feed hopper with adjusting shutter arranged on top main roller and fitted with curvilinear guide plate. Feed roller is arranged inside said hopper above main top roller. Said feed roller has grooves to clean blades mounted below rollers. Guide plate is mounted behind cleaning blade of the top main roller. Guide plate consisting of two linear parts smoothly connected by curvilinear section with curvature radius R=0.17 m and plate arranged vertically behind bottom roller cleaning blade and accommodating preservative solution feed nozzles form chamber designed to mix crushed grain and preservative. Distance from nozzles to guide plate is equal to H=0.16 m.
EFFECT: higher efficiency of adding preservative to moist crushed grain and its storability.
