A bucket elevator for lifting parboiled paddy (bulk density $=840 \mathrm{~kg} \mathrm{~m}^{-3}$ ) is operated at a linear speed of $2 \mathrm{~m} \mathrm{~s}^{-1} .$ The width of the bucket is $25.4 \mathrm{~cm}$ and its cross section is making a subtending angle of $75^{\circ}$ at the centre of a circle having $12.7 \mathrm{~cm}$ radius. The space between two adjacent buckets on the elevator belt is $40 \mathrm{~cm} .$ If the buckets are filled to $80 \%$ of their volumetric capacity, the lifting capacity of elevator in kg min $^{-1}$ (round off to 2 decimal places) is____________
