How to distinguish lime, slaked lime, lime paste

The original lime production process is the limestone and fuel ( wood ) layered laying, ignition burning week. In modern times, mechanized and semi-mechanized shaft kilns, rotary kilns, boiling furnaces and other equipment are used for production. The calcination time is also shortened accordingly. It takes only 2-4 hours to produce lime by rotary kiln, which can increase the production efficiency by more than 5 times than that by vertical kiln. In recent years, there have been significant energy-saving processes and equipment such as cross-flow, double-slope and oil-fired annular shaft kilns and short rotary kilns with preheaters. The fuel has also been expanded to coal, coke, heavy oil or liquefied gas.

Lime powder is a fine powder obtained by grinding block lime, and its main component is CaO.

Lime powder is a kind of powder which is obtained by curing the block lime with appropriate amount of water, also known as slaked lime. Its main component is Ca ( OH ) 2.

Lime paste is a paste obtained by curing massive lime with more water ( about 3-4 times the volume of lime ). Also known as lime slurry. Its main component is also Ca ( OH ) 2.

In terms of the properties and uses of lime, lime is white or gray block. In order to facilitate use, block lime often needs to be processed into lime powder, lime powder or lime paste.
