Detailed Description

As shown in figure 1, the rolling macadam mixture gradation optimization device comprises a rectangular distribution hopper 1, a trapezoidal diversion trench 2 positioned on the lower side of a discharge port of the distribution hopper 1, a first material distribution baffle 3 is arranged in the material distribution hopper 1, the first material distribution baffle 3 is strip-shaped and is arranged in parallel with the long edge of the material distribution hopper 1, a second material distribution baffle plate 4 is arranged in the guide groove 2, the second material distribution baffle plate 4 is trapezoidal and is clamped with the inner side wall of the guide groove 2, the first material distribution baffle 3 and the second material distribution baffle 4 are fixedly connected, an adjustable connecting plate 5 which is arranged in parallel with the short edge of the material distribution hopper 1 is also arranged above the material distribution hopper 1, the adjustable connecting plate 5 is fixedly connected with the material distributing hopper 1, a strip-shaped groove 51 is formed in the adjustable connecting plate 5 along the length direction of the adjustable connecting plate, a clamping block 52 is movably arranged in the strip-shaped groove 51, and the clamping block 52 is fixedly connected with the first material distributing baffle plate 3; the length of adjustable connecting plate 5 is greater than the width of dividing hopper 1, divides the hopper 1 left and right sides to be equipped with otic placode 11 respectively, adjustable connecting plate 5 is through bolt 6 with its fixed mounting on the otic placode 11 of dividing hopper 1, adjustable connecting plate 5 is two, and an adjustable connecting plate 5 is located and divides hopper 1 middle part, and another adjustable connecting plate 5 is located and divides hopper 1 rear portion, all is equipped with the scale on every adjustable connecting

plate

5, 2 bottoms in trapezoidal guiding gutter are equipped with the water conservancy diversion mouth.

When the method is used specifically, taking the diameter of the separated material as an example, the grading of the crushed stone mixture produced by the mechanically-rolled stone mill is analyzed, according to the grading optimization adjustment requirement, the crushed stone mixture produced by the mechanically-rolled stone mill is divided into two grades, one grade is a coarse crushed stone mixture, the other grade is a fine crushed stone mixture, and the proportion of the mixture with the size of 0-Dmm (D is the maximum particle size of the mechanically-rolled mixture) and the size of 0-6mm is determined to be required to be divided.

Under the working condition 1, part of crushed stones with the thickness of 6mm-Dmm needs to be shunted, and under the working condition 2, fine aggregates with the thickness of 0-6mm needs to be shunted.

a. A layer of 6mm sieve is additionally arranged on the vibrating screen, so that the mechanically-rolled crushed stone mixture is divided into two grades of mixtures.
