AASHTO #1 has a top rock size of 2 to 4 inches. These crushed stones are bulky, and their size makes them impractical for surfacing material uses. However, AASHTO #1 is excellent for subgrade stabilization. It is a clean material that won't compact, allowing for many construction applications. AASHTO #1 is the largest crushed stone variety ...

If our problem had covered a crushing condition calling for 80 instead of 85% passing the …
Each of these uses will require a specific size or gradation of aggregate, including the percentage of material allowed for each sieve size in the gradation. This can be critical for the strength of the material, …
Analysis and modeling of cone crusher output. The operational part of the cone crusher is the crushing chamber, which consists of a mantle and a concave liner. As shown in Fig. 1, the axis of the mantle intersects the axis of the crushing chamber at point O, which is the pivot point. The angle between the two axes is γ, which is the eccentric ...
Crushed stone #411 #411 is a mixture of larger, fine, and dust particles. It combines #57 stone and #10 screenings and dust. The small particles and dust help to solidify the material into a good, hard base. This makes it an ideal stone for a base for paver patios, stone walks, retaining walls, artificial turf, driveways, etc.
Dry the Sample in an Oven. The drying process is a very important step because the weight will be the key indicator for creating the aggregate sieve analysis. Moisture in the material adds weight falsifying the results. Reweigh the Sample. This is your reference weight to check if your screening results add up. Split the sample evenly.

Feed gradation. Moisture content. A measure of the size reduction achieved for a particular crusher application is the reduction ratio. A cone crusher in a secondary crushing application will typically work with a 3.5:1 to 5:1 reduction ratio. Tertiary cone crusher configurations typically work with a reduction ratio of 2.5:1 to 4:1.

For the 1-in. screen below the roll crusher the capacity has no correction factor and the area needed is 32/2.1 = 15.2 sq ft. To handle the output from a 40 x 24 roll crusher the screen will have to be at least 24 in. wide. Perhaps it will be more effective to use one continuous screen of at least 20.1 + 15.2 = 35.3 sq ft.
