What contain the thinnest one grade of cold aggregate is one group, the corresponding A feed system; Another group is thick cold aggregate, corresponding B feed system.
Corresponding A feed system cold burden group: rubble 4.75-9.5mm (B material), machine-processed sand 0-2.36mm (D material)
Corresponding B feed system cold burden group: rubble 9.5-19mm (A material), rubble 2.36-4.75mm (C material)
Sieve aperture is selected:
Being spaced apart 2.36-4.75mm between A feed system cold burden group B material and the D material selects reference table to select 4.5mm with reference to the sieve aperture specification of baffle vibratory sieve; The maximum sieve aperture is selected 13mm (also can select the sieve aperture smaller or equal to 23mm greater than 13mm), still divides two kinds of entering hot aggregate bins to expect corresponding with B material, D after the screening of gathering materials;
Be spaced apart 4.75-9.5mm between B feed system cold burden group A material and C expect and select reference table selection 8mm, maximum sieve aperture to select 23mm, still divide two kinds of entering hot aggregate bins to expect corresponding after the screening of gathering materials with A material, C with reference to the sieve aperture specification of baffle vibratory sieve.
The baffle vibratory sieve sieve aperture specification of hot aggregate screening machine confirms that the A feed system is 4.5mm, 13mm; The B feed system is 8mm, 23mm.
Example 2: certain engineering AC-25 compound use is gathered materials for six kinds and is respectively rubble 19-31.5mm (A material), rubble 9.5-19mm (B material), rubble 4.75-9.5mm (C material), rubble 2.36-4.75mm (D material), machine-processed sand 0-2.36mm (E material), natural sand 0-4.75mm (F material).
Divide into groups:
A kind of being put in same group, then can be regarded as in mechanism sand 0-2.36mm (E material), natural sand 0-4.75mm (F material) merging that specification is close
Cold aggregate is divided into two groups by the sized baffle: first group of A feed system is A material, C material, E material and F material; Second group of B feed system is B material, D material.
The ratio of E material and F material is controlled from the cold burden feed system.
Sieve aperture is selected:
First group of A feed system, is separated with 9.5-19mm, 2.36/4.75-4.75 between being interrupted at maximum particle diameter 31.5mm, selects sieve aperture 35mm, 16mm, 5.5mm, and being divided into three kinds after the screening of gathering materials, to get into hot aggregate bins corresponding with A material, C material, E material and F material respectively.
Second group of B feed system, is interrupted and is spaced apart 4.75-9.5mm maximum particle diameter 19mm, selects sieve aperture 23mm (also can select the sieve aperture smaller or equal to 35mm greater than 23mm), 8mm, and the screening back that gathers materials is divided two kinds, and to get into hot aggregate bins corresponding with B material, D material respectively.
The baffle vibratory sieve sieve aperture specification of hot aggregate screening machine confirms that the A feed system is 35mm, 16mm, 5.5mm; The B feed system is 23mm, 8mm.
