The invention discloses a gravel production
gradation adjustment device. The gravel production
gradation adjustment device comprises a grading screen, and the grading screen comprises multiple
layers of screens; the screen I of which the mesh
diameter is 4.75 mm, the screen II of which the mesh
diameter is 3 mm, the screen III of which the mesh
diameter is 1.25 mm, the screen IV of which the mesh diameter is 0.25 mm, the screen V of which the mesh diameter is 0.16 mm and the screen VI of which the mesh diameter is 0.075 mm are sequentially arranged from top to bottom; the
discharge ends of the screens are connected to material collection hoppers; each material collection hopper is connected to one bin through a pipeline; weighing devices are arranged at
discharge openings of the bins; a belt conveyer is arranged in front of the weighing devices; and the
discharge end of the belt conveyer is connected to a stirring
machine. According to the gravel production
gradation adjustment device, classification of six-grade stone of which the particle sizes are 0 mm to 0.075 mm, 0.075 mm to 0.16 mm, 0.16 mm to 0.25 mm, 0.25 mm to 1.25 mm, 1.25 mm to 3 mm, and 3 mm to 4.75 mm can be achieved, weighing is achieved through the weighing devices, finally, stone of the required gradation is matched according to different utilization requirements and is put into the stirring
machine to be stirred and mixed, stone
powder of the required gradation can be better prepared, preparation quality of stone
powder is improved, selectivity is high, and gradation adjustment can be effectively controlled.
