Talc powder production is generally divided into four types: talc coarse powder processing (0-3mm), fine powder processing (20-400 mesh), and ultrafine powder processing (400-1250 mesh) and micro-powder processing (1250 mesh — 3250 mesh).

The first stage: crushing of raw materials

The bulk talc material is broken by the crusher to the feeding fineness (15mm-50mm) that can enter the grinding machine.

The second stage: grinding

The small pieces of broken talc material are sent to the storage hopper by the elevator, and then are uniformly and quantitatively sent to the grinding room of the mill by the feeder.

The third stage: grading

The material after grinding is graded by the classification system, and the unqualified powder is graded by the classifier and returned to the main machine for re-grinding.

Stage 4: Collection of finished products

The powder conforming to the fineness enters the dust collector with the air flow through the pipeline for separation and collection. The collected finished powder is sent to the finished product silo through the discharge port by the conveying device, and then is uniformly packed by the powder filling tank truck or automatic baler.

Calcium carbonate is a chemical compound with the formula CaCO3. It is a common substance found in rocks as the minerals calcite and aragonite, and it is the main component of pearls and the shells of marine organisms, snails, and eggs. Calcium carbonate has a variety of uses, including in the production of building materials, as a filler in plastics and coatings, and as a dietary supplement.

The manufacturing process for calcium carbonate involves several steps:

Quarrying: Calcium carbonate is extracted from the ground using a variety of methods, including open-pit mining, underground mining, and quarrying. The material is typically found in limestone, chalk, or marble deposits.

Crushing and grinding: Once the raw material has been extracted, it is crushed and ground into a fine powder. This powder is then transported to a processing plant.

Purification: The powder is purified to remove impurities such as silica, iron, and aluminum. This is typically done using a combination of chemical and physical processes.

Precipitation: The purified powder is mixed with water and a chemical called soda ash (sodium carbonate) to create a slurry. Carbon dioxide gas is then bubbled through the slurry, causing the calcium carbonate to precipitate out of the solution.

Drying and packaging: The precipitated calcium carbonate is then dried and milled to create a fine powder. The powder is then packaged and shipped to customers.

Equipment used in the manufacturing process includes:

Crushers: These are used to crush the raw material into smaller pieces.

Grinding mills: These are used to grind the raw material into a fine powder.

Classifiers: These are used to separate the powder into different particle sizes.

Mixers: These are used to mix the powder with water and other chemicals.

Reactors: These are used to mix the powder with soda ash and carbon dioxide to precipitate the calcium carbonate.

Dryers: These are used to dry the precipitated calcium carbonate.

Calcium carbonate (CaCO3) is a chemical compound that exists in different forms, including two main crystal structures: calcite and aragonite. The difference between light and heavy calcium carbonate is primarily based on their particle size and density.

Light calcium carbonate, also known as precipitated calcium carbonate (PCC), is produced through a chemical reaction in which limestone (calcium carbonate) is dissolved in acid, and then re-precipitated using a precipitation agent. The resulting product has a smaller particle size and lower density compared to heavy calcium carbonate, making it ideal for use in applications that require a fine particle size, such as in paper coatings, plastics, and rubber.

On the other hand, heavy calcium carbonate, also known as ground calcium carbonate (GCC), is produced by grinding and milling limestone. The resulting product has a larger particle size and higher density than PCC, making it suitable for use in applications that require a coarser particle size, such as in construction materials like concrete and mortar.

In summary, the primary difference between light and heavy calcium carbonate is their particle size and density, which determine their suitability for specific applications.
