What is the processing technology of calcium carbonate powder?

As an inorganic powder material, calcium carbonate powder is a non-toxic, odorless and tasteless environmental protection material, which is widely used in plastics, rubber, paper making, building materials and other fields. For example, plastics. At present, the total output of plastic products and materials in China can reach 70 million tons/year. Calcium carbonate is a large amount of powder filler in plastic processing, and the amount of calcium carbonate filled in plastics every year is up to 10 million tons. What is the processing technology of calcium carbonate powder?

What is the processing technology of calcium carbonate powder?

Through the continuous innovation of science and technology, the application scope of calcium carbonate powder is also expanding. Increasing the use of calcium carbonate is of great significance for energy conservation and emission reduction. With such a wide range of uses and applications of calcium carbonate powder, what is the processing technology of calcium carbonate?

Processing technology: Crushing: Crush large pieces of calcium carbonate materials to the feed size of the grinder.

Grinding: calcium carbonate conforming to the feed size of the mill is sent to the silo by the elevator, and then sent to the grinding chamber of the mill by the vibrating feeder in a uniform and quantitative manner for grinding.

Grading: the grinded materials are graded by the grader, and the unqualified molecules are graded by the grader and returned to the host machine for regrinding.

Powder collection: after the powder separator is graded, the powder meeting the fineness requirements enters the dust remover with the air flow through the pipeline for separation and collection. The collected finished powder is sent to the finished product warehouse through the outlet by the conveyor, and then packaged by the powder loading tanker or automatic packaging machine.

After knowing the processing technology, we can probably refer to which types of equipment are suitable for different processing of carbonic acid, such as LM vertical roller mill, MTW European mill, 5X European intelligent mill, etc. MW ring mill and LUM superfine vertical mill can be used for superfine grinding. CM European rough grinding can be used for rough grinding. In addition, when selecting equipment and manufacturers, we try to go to the customer's site to see, contact several manufacturers for comparison, and then make a decision. If you have questions about milling, you can learn more about it.

Is calcium carbonate powder harmful to human body?

Generally, calcium carbonate powder is harmless to human body. In pregnant women, lactating women, the elderly, children and other people, calcium carbonate is a calcium supplement medicine, mainly used to prevent and treat calcium deficiency. The treatment is osteoporosis. Generally speaking, calcium carbonate is harmless to human body, but excessive intake of calcium carbonate powder will cause some adverse reactions or side effects.

Gastrointestinal flatulence is a common adverse reaction of calcium carbonate powder. Some patients suffer from upper abdominal discomfort due to the discharge of carbon dioxide. Gastric acid is an insoluble compound that needs to be dissolved by gastric acid. Therefore, it is appropriate to take it within one hour after meals. If taken before sleep, it may cause gastrointestinal diseases and increase the risk of urinary stones.

Take medicine under the guidance of the doctor, treat symptomatically, do not take medicine blindly, go to the hospital for treatment of other uncomfortable symptoms in time, pay attention to light diet in life, eat more fresh fruits, do not eat spicy and stimulating food, avoid excessive fatigue and staying up late, and exercise appropriately.
