Calcium carbonate (CaCO₃) is a widely used inorganic non-metallic material, extensively applied in plastics, paper, coatings, rubber, and many other industries. Its performance—particularly in terms of particle size and morphology—depends almost entirely on one crucial stage: grinding. This Q&A aims to explore the necessity, key equipment, and technologies involved in calcium carbonate grinding. Q1: Why […]

In the history of the plastics industry, calcium carbonate has long been regarded as a low-cost filler, valued mainly for reducing raw material costs. However, with breakthroughs in processing technology and the evolution of application demands, this traditional perception is being completely redefined. Today, calcium carbonate has transformed into a functional modifier that combines three

In modern industrial systems, calcium carbonate (CaCO₃) is known as the “grain of industry” for its abundant resources, stable properties, and wide range of applications. As an essential non-metallic mineral raw material, calcium carbonate not only supports traditional manufacturing industries but also plays a vital role in emerging sectors and high-tech fields. From plastics and

According to different production methods, calcium carbonate can be classified into ground calcium carbonate (GCC), precipitated calcium carbonate (PCC), colloidal calcium carbonate, and crystalline calcium carbonate. Among these, GCC is produced through direct mechanical grinding. Ultra-fine calcium carbonate is an essential non-metallic mineral raw material, widely used due to its abundance, low cost, and performance-enhancing

In the vast world of chemical raw materials, there is a seemingly ordinary yet highly powerful material that is quietly transforming the manufacturing processes and product performance of multiple industries. This material is modified calcium carbonate. After surface activation treatment, modified calcium carbonate is no longer just a simple filler but has become a key

Active calcium carbonate, through surface activation and modification, has evolved from a basic filler into a multifunctional material. It significantly enhances the performance and efficiency of industries such as rubber, plastics, papermaking, coatings, and building materials, while drastically reducing costs. It has become a secret weapon for the green development of manufacturing industries. In the

Calcium carbonate is the most commonly used inorganic powder fillers. It is inexpensive, abundant, non-toxic, and odorless. It has a whiteness of up to 96%, can be easily colored, and has excellent chemical stability. It is easy to dry and widely used in many plastics. Calcium Carbonate There are three kinds of powder fillers of

Limestone is a key raw material for the production of cement, concrete aggregates, and lime. Its crushing and grinding generally follow a dry process. The process varies based on the specific application. For limestone used in metallurgy and road construction, the material is typically crushed and screened. For limestone used as a feed additive or

Currently, the amount of fillers and pigments used in papermaking ranks second only to fiber as one of the most important raw materials. Common papermaking fillers include calcium carbonate, talc, kaolin, wollastonite, bentonite, and others. As the acidic papermaking process gradually shifts towards neutral and alkaline processes, calcium carbonate, as an important raw material in

The limestone grinding process involves mining, crushing, and processing natural limestone ore into industrial raw materials of various specifications. It is widely applied in construction, building materials, chemicals, and metallurgy. Limestone Characteristics and Applications Chemical composition: Mainly calcium carbonate (CaCO₃), with small amounts of magnesium oxide, silica, and other impurities. Main applications: Limestone Mining Process
