What's the difference between 2a and 2b stone?

The only difference between 2B and 2A is that the 2A has some Limestone dust (10) mixed in with the stone, and tends to compact better. For driveways with mud problems, consider putting a base of #3 or #4 Limestones with 2B or 2A Limestone on top.

Limestone mills for all requirements | Gebr. Pfeiffer

Limestone lumps are ground, classified, and dried in Pfeiffer MPS vertical roller mills. The fineness of pulverized limestone can be set within a wide range (0.02 to 0.2 mm). If required, classifier grits can be evacuated for another classification in a downstream Pfeiffer separator and separated into limestone sands (0.1 to 1.5 mm) in ...

Sedimentary Rock Identification | Physical Geology

Limestone fizzes in dilute hydrochloric (HCl) acid, because it is composed of the mineral calcite, CaC03. Some limestone contains chert, which is very, very hard silica (like flint). It typically weathers to brown on the surface and occurs in nodules and occasionally replaces fossil shells.

Sedimentary Rocks - Tulane University

Sedimentary Rocks. Rivers, oceans, winds, and rain runoff all have the ability to carry the particles washed off of eroding rocks. Such material, called detritus, consists of fragments of rocks and minerals.When the energy of the transporting current is not strong enough to carry these particles, the particles drop out in the process of sedimentation.

Limestone is converted to quicklime through calcining in rotary or vertical kilns. In the lime process, for every ton of saleable quicklime produced, about 2 tons of 'pure' limestone or up to 6 tons of impure limestone is consumed. Limestone consumption depends on the type of product, limestone purity,

What are sedimentary rocks? - USGS

Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface. Sedimentary rocks often have distinctive layering or bedding. Many of the picturesque views of the desert southwest show mesas and arches made of layered sedimentary rock.Common Sedimentary Rocks:

In vertical kilns, the presence of very small size of limestone block the voids between limestone, interfering with gas passage, and thus with the heat transfer, causing uneven calcination. In addition, small limestone particles (less than 3 mm) tend to degrade and cause generation of fines which need to be removed by dust collectors.
