Precipitated calcium carbonate limestone grinding mill
Precipitated calcium carbonate (PCC), also known as synthetic calcium carbonate, is a limestone that has been purified and processed to remove impurities. PCC is white in color and is used in a variety of industries for various purposes. PCC is commonly used as a filler material in paper, paint, plastics, and rubber. It is also used in the food industry as an additive to food items such as flour, milk powder, and baby formula. PCC is also used in the pharmaceutical industry as an inert ingredient in tablets and capsules. Precipitated calcium carbonate can be made from either limestone or marble. To produce PCC from marble, calcination and carbonation processes are used.
What is precipitated calcium carbonate?
Precipitated calcium carbonate (PCC) is a product derived from limestone that has been through a process of calcination and hydration. PCC is widely used as a filler material in paper, paint, rubber, and plastics. It is also an effective adsorbent of colorants and impurities in water-based systems. PCC has a relatively high degree of purity and uniform particle size, making it an ideal filler material.
How is precipitated calcium carbonate made?
Precipitated calcium carbonate (PCC) is made by direct carbonation of quicklime, hydrated lime, or limestone. The resulting calcium oxide is then reacted with water to form calcium hydroxide. The resulting calcium hydroxide is then carbonated by reacting it with gaseous carbon dioxide to form PCC.
PCC is generally made by one of two processes:
1) The 'lime soda' process, in which calcium hydroxide is reacted with gaseous carbon dioxide to form PCC;
2) The 'carbonation' process, in which quicklime, hydrated lime, or limestone is first calcined to form calcium oxide, which is then reacted with water to form calcium hydroxide, which is then reacted with gaseous carbon dioxide to form PCC.
How to use precipitated calcium carbonate?
Precipitated calcium carbonate is a versatilechemical compound It has many uses in different industries, such as rubber, plastics, paper, and paint.
The most common use for precipitated calcium carbonate is in the production of paper. PCC is used as a filler to increase the opacity, brightness, and bulk of the paper. It is also used as a coating to improve the surface finish and printability of the paper.
In the paint industry, PCC is used as an extender and filler. It increases the hiding power of the paint and its durability. PCC is also used in some enamel paints. In the plastics industry, PCC is used as a filler and strengthening agent in many products such as vinyl siding and pipes.
PCC can also be used in rubber products such as tires and hoses. It improves the elasticity and strength of the rubber.
What are the benefits of using precipitated calcium carbonate?
Precipitated calcium carbonate is a versatile additive for use in a wide range of industries. As a filler, it improves the strength and durability ofpaper products. As a coating agent, it gives paper a smooth, glossy finish. As an abrasive, it can be used in toothpastes and other products that require a gentle cleaning action. In addition to its many uses, precipitated calcium carbonate is also environmentally friendly because it is derived from limestone, a renewable resource.
How to choose a precipitated calcium carbonate grinding mill
There are several factors to consider when choosing a precipitated calcium carbonate grinding mill. The first is the size of the mill. The second is the type of media used to grind the calcium carbonate. The third is the feed rate and fourth is the discharge rate.
The size of the mill will determine the capacity of the grinding circuit. A small mill may only be able to handle a few hundred pounds per hour while a large mill could handle several tons per hour. The type of media used in the mill will also affect the capacity. Bead mills use small spheres of glass or ceramic to grind calcium carbonate into a fine powder while ball mills use larger steel balls to achieve the same results.
The feed rate is how fast material is fed into the grinding chamber and can be controlled by either manual or automatic means. The discharge rate is how fast ground material leaves the grinding chamber and can also be controlled. Higher feed rates and lower discharge rates will produce finer particles while lower feed rates and higher discharge rates will coarser particles.
Conclusion
Precipitated calcium carbonate is a versatile chemical compound that has many uses in different industries. It can be used as a filler in plastics, a whitening agent in cosmetics, and a absorbent in paper products. limestone grinding mill is an effective way to produce precipitated calcium carbonate powder with a wide range of particle sizes. This type of milling equipment is able to produce consistent results and provides good value for money.
