SBM expert explains for you natural arenaceous with the mechanism arenaceous
Natural arenaceous with the mechanism arenaceous be gone to by wide application in fundamental project, choice artificial sand or choice mechanism are arenaceous be about to have to these two kinds of arenaceous characteristics above all know clearly quite. SBM expert explains a mechanism with everybody today arenaceous and natural arenaceous.
Natural arenaceous according to fineness modulus standard can differentiate for 4 grade, it is respectively:
Thick arenaceous: Fineness modulus is 3.7-3.1, average bead diameter is 0.5mm above;
In arenaceous: Fineness modulus is 3.0-2.3, average bead diameter is 0.5-0.35mm;
Fine arenaceous: Fineness modulus is 2.2-1.6, average bead diameter is 0.35-0.25mm;
Especially fine arenaceous: Fineness modulus is 1.5-0.7, average bead diameter is 0.25mm the following.
Fineness modulus is bigger, express arenaceous thicker. Common concrete is used arenaceous fineness modulus limits is in 3.7-1.6, with in arenaceous advisable, perhaps use thick arenaceous add a few fine arenaceous, its scale is 4:1.
However natural arenaceous be in short supply increasingly, and the place that needs to use arenaceous stone is increasing however. And as a result of natural arenaceous be in short supply increasingly, with the mechanism arenaceous come natural arenaceous breach becomes fill hasten of general trends place. Make artificially with respect to need so arenaceous will satisfy the market to need. Make artificially arenaceous also be called a mechanism arenaceous, his definition is: The mechanism is arenaceous it is via dividing earth is handled, the bead way that makes by mechanical and broken, screening is less than the rock grain of 4.75mm. But do not include soft qualitative rock, efflorescent petrosal grain.
The norms with arenaceous mechanism: Arenaceous norms is pressed fineness modulus (Mx) cent is thick, medium, fine 3 kinds. Among them:
Thick arenaceous fineness modulus is 3.7-3.1;
In arenaceous fineness modulus is 3.3-3.0;
Fine arenaceous fineness modulus is 2.2-1.6.
Arenaceous grade: Arenaceous grade asks by its technology cent is: I, II, III3 grade, utility:
I kind the concrete that arenaceous practical Yu Jiang spends grade to be more than C6;
II kind practical Yu Jiang spends grade C30-C60 to reach fight aspic, the concrete of impervious or other demand, water industry concrete;
III kind the concrete that arenaceous practical Yu Jiang spends grade to be less than C30 and build mortar.
Characteristic: Arenaceous bead diameter is between 4.75~0.15mm, and the Shi Fenying that is less than 0.075mm has affirmative limit, cent of its bead class is 4.75, 2.36, 1.18, 0.6, 0.3, 0.15, had better want successive, and the per cent that each class wants to have affirmation, its bead had better show cube, to its needle piece form content also has affirmative demand.
Use commonly usedly make arenaceous rock granite, basalt, natural cobble, sandstone, diabase waits. What its make is arenaceous differ by petrosal sort, have different intensity and different use, be aimed at the raw material of different hardness grade, optional choose deploys the making that suit arenaceous aircraft equipment.
The choice of mechanism arenaceous device: The equipment that suits mechanism arenaceous product line at present has a lot of, the crusher of type having jaw with relatively general application, conic type crusher, strike back type crusher, vertical scroll of painting or calligraphy pounds type crusher (5X makes arenaceous machine, VSI make arenaceous machine) etc, the client can be mixed according to investment dimensions crop, give the actual production such as makings to ask to choose appropriately.
- Spray dryer stresses a feature mediumly in numerous dryer
- Stroke type crusher is in extremely subtle and broken in apply
- Strike back the type of type crusher actors or actress defect
