Abstract

Мельница для размола зерна, содержащая корпус с приемной воронкой и выпускным отверстием, расположенные внутри корпуса неподвижный и вращающийся на вертикальном валу жернова с рифленой поверхностью, между которыми образован кольцевой рабочий зазор, и установлены они большим основанием вниз, причем рифленая поверхность жерновов имеет три зоны, характеризующиеся различными числом, уклоном и высотой рифлей, обусловливающими дифференцированный режим размола, отличающаяся тем,что, с целью возможности равномерного распределения помола, конусообразные жернова имеют зону в виде многозаходных спиральных канавок и регулируемую зону истирания крупки до муки, образованную конусом с острым углом к горизонтали.A mill for grinding grain, containing a housing with a receiving funnel and an outlet, located inside the housing stationary and rotating on a vertical shaft of a millstone with a corrugated surface, between which an annular working gap is formed, and they are installed with a large base down, and the corrugated surface of the millstones has three zones, characterized by a different number, slope and height of the flutes, causing a differentiated grinding mode, characterized in that, in order to ensure uniform distribution of grinding, nusoobraznye grindstones have a zone in multistart helical grooves and an adjustable area to abrasion semolina flour, is formed by a cone with an acute angle to the horizontal.

Claims

A mill for grinding grain, containing a housing with a receiving funnel and an outlet, located inside the housing stationary and rotating on a vertical shaft of a millstone with a corrugated surface, between which an annular working gap is formed, and they are installed with a large base down, and the corrugated surface of the millstones has three zones, characterized by a different number, slope and height of the flutes, causing a differentiated grinding regime, characterized in that that, with a view to the possibility of uniform distribution of grinding, the cone-shaped millstones have a zone in the form of multi-helical spiral grooves and an adjustable grinding zone of grains to flour, formed by a cone with an acute angle to the horizontal.
