How is calcium carbonate made with vertical mill?
Calcium carbonate is a common mineral that can be found in various natural sources such as limestone, marble, and chalk. But how exactly is it made? Let’s take a closer look.
The process of making calcium carbonate starts with extracting limestone from quarries. The rock is then crushed into smaller pieces and transported to lM Vertical roller mills where it undergoes further crushing and pulverizing. This results in fine particles of calcium carbonate.

Next, the ground calcium carbonate goes through a process called carbonation or precipitation. In this step, carbon dioxide gas is bubbled through a solution containing calcium hydroxide derived from the previous step. This reaction forms solid calcium carbonate precipitates which are later filtered and dried.
To achieve ultrafine particle sizes required for certain applications, additional grinding steps may be employed using specialized equipment like ultrafine grinding machines. These machines use high-speed rotating blades or media to break down the larger particles into smaller ones.
The final product obtained after all these processes is a fine powder of calcium carbonate with various particle sizes depending on the desired application. It can be used in industries ranging from construction materials to pharmaceuticals due to its versatility and unique properties.
The production of calcium carbonate involves several stages including extraction, crushing, grinding, carbonation/precipitation, and drying. Each step plays an important role in obtaining the desired quality and particle size distribution for specific applications.
Spodumene: According to the hard rock crushing process, the crushed product is generally 5-40mm, combined with different design requirements of customers, two-end or three-stage crushing, high-grade crushed products (above 4-5%) can be directly used in the metallurgical process to produce lithium carbonate Or lithium hydroxide, the particle size of the finished product is generally around 20-40mm; low-grade generally requires ball mill grinding and separation, and the particle size of the finished product is generally around 5-20mm;
