Limestone – Electro Magnetic Industries

Limestone

The main component of limestone is calcium carbonate (CaCO3). Lime and limestone are applied in a lot of building materials. It is also an important raw material in many industries. Limestone can be directly processed into aggregated rock and calcined into quicklime. Lime are divided into two kinds: quicklime and slaked lime. The main component of quicklime is CaO, the general was massive, when it is with high purity, it is pure white; When it contains impurity, it looks pale gray or faint yellow. It turns into slaked lime (hydrated lime) if getting wet. The main ingredient is Ca (OH) 2. Slaked lime can be formulated into mortar, lime plaster, lime mortar, used as coating materials and tile adhesives. Limestone is also called calcite, marble, chalk, aragonite, marble in some places.

Limestone processing production process

In limestone processing, these machines are widely applied: mill (Raymond mill or high pressure mill), jaw crusher, hammer crusher, impact crusher, sand making machine and other equipment.

First stage

Crusher to break large stones into smaller ones.

Second stage

Suitable particles to be transferred to Raymond mill.

Third stage

Finished products, after being ground in the Raymond mill and separated by the classifier. Dust removing system should be equipped, to avoid pollution.

Fourth stage

Storage of finished products for packaging.

Equipment needed

The main component of limestone is calcium carbonate (CaCO3). Lime and limestone are applied in a lot of building materials. It is also an important raw material in many industries. Limestone can be directly processed into aggregated rock and calcined into quicklime. Lime are divided into two kinds: quicklime and slaked lime. It requires the use of crushing and grinding equipment in limestone process.
