Calcium carbonate property & calcium carbonate grinding

Posted: 2015-05-14

• Calcium carbonate is an inorganic compound, commonly existed in travertine, limestone, marble and so on. The formula is CaCO3, neutral, substantially insoluble in water, soluble in hydrochloric acid. It is a common substance on Earth, exists in the aragonite, calcite, chalk, limestone, marble, travertine and other rocks, is also the main component of animal bones or shell.

   

  It is white solid, tasteless, odorless, has amorphous and crystalline two types.

  Moh hardness: 3 degree

   

  In case of dilute acetic acid, dilute hydrochloric acid, dilute nitric acid intumescent and dissolved. Decomposed into calcium oxide and carbon dioxide at 101.325kPa when heated to 900 ℃. Under an atmosphere of calcium carbonate was heated to 900 ℃, decompose into lime and carbon dioxide (Industrial Preparation CO₂):(For the high temperature reaction conditions) Will react with dilute hydrochloric acid and calcium carbonate, will be presented effervescence produce calcium chloride, water and carbon dioxide (laboratory preparation CO₂): CaCO3 mixed with water leads to excessive carbon dioxide, calcium bicarbonate solution is generated. Calcium carbonate and carbonated water (rain) the reaction of calcium bicarbonate. Put turbid lime water into CO2, precipitation disappears.

   

  Calcium carbonate powder grinding plant can be divided into various types and models, and the main calcium carbonate powder grinding plant include calcium carbonate vertical roller grinding mill, calcium carbonate ultrafine grinding mill, calcium carbonate Raymond mill, calcium carbonate ball mill and so on. Among this powder grinding processing plant, HGM calcium carbonate ultrafine grinding mill is our star product, it can easily solve your problem.
