Shale is the most common sedimentary rock, accounting for about 70 percent of the rock in the Earth's crust. Shale is a fine-grained rock made from compacted mud and clay. The defining characteristic of shale is its ability to break into layers or fissility. Black and gray shale are common, but the rock can occur in any color.

Limestone is by definition a rock that contains at least 50% calcium carbonate in the form of calcite by weight. All limestones contain at least a few percent other materials. These can be small particles of quartz, feldspar, or clay minerals delivered to the site by streams, currents and wave action.

Aggregate Crushing Value = 100(W2/W1) percent where: W2 = Weight of fraction passing the appropriate 2.36 mm sieve. W1 = Weight of dry sample. Normally, the percentage of fines should fall between 7.5 and 12.5. If it falls outside this range, conduct a new test at a load adjusted to bring the percentage of fines within the range of 7.5 to 12.5.

It can crush coarse, medium, and fine materials below 500mm and compressive strength below 350MPA, such as granite, limestone, concrete, etc. Impact crusher is widely used in various ore crushing, railway, highway, energy, cement, chemical, construction, and other industries. The output size is adjustable. 4. Screening.

Ensure that the limestone feed size is appropriate for the crushing equipment to minimize the production of fine particles.Implement a screening process to remove smaller particles before they ...

Fines content is the percent passing a No. 200 sieve, whereas dust ratio is defined as the ratio of percent passing a No. 200 to the percent passing a No. 40 sieve. …
