重质碳酸钙的生产工艺流程
英文回答:
reactor pressure vessel The production process of heavy calcium carbonate involves several steps. First, limestone is mined from quarries or extracted from underground mines. Limestone is a sedimentary rock composed mainly of calcium carbonate. It is crushed into small pieces and then transported to a processing plant.
At the processing plant, the limestone is further crushed and ground into a fine powder. This powder is then subjected to a chemical reaction called carbonation. Carbon dioxide gas is introduced into the powder, causing it to react with the calcium carbonate and form calcium carbonate crystals. The carbonation process is typically carried out in a reactor vessel under controlled conditions of temperature and pressure.
After carbonation, the resulting calcium carbonate crystals are separated from the remaining impurities. This is done through a process called filtration or sedimentation. The crystals are then washed and dried to remove any residual moisture.
The dried calcium carbonate crystals are then subjected to a process called milling. This involves grinding the crystals into a fine powder with a specific particle size distribution. The milled powder is then packaged and ready for distribution.
The production of heavy calcium carbonate requires careful control of various parameters such as the quality of the limestone, the carbonation conditions, and the milling process. These parameters can affect the properties of the final product, such as its particle size, brightness, and chemical purity.

重质碳酸钙的生产工艺涉及几个步骤。首先,石灰石从采石场或地下矿井中开采出来。石灰石是一种主要由碳酸钙组成的沉积岩。它被粉碎成小块,然后运送到加工厂。
在加工厂,石灰石进一步被粉碎和研磨成细粉。这个粉末然后经历一个称为碳化的化学反应。二氧化碳气体被引入粉末中,使其与碳酸钙发生反应并形成碳酸钙晶体。碳化过程通常在控制的温度和压力条件下在反应器中进行。
碳化后,得到的碳酸钙晶体与剩余的杂质分离。这是通过过滤或沉淀的过程来完成的。然后将晶体进行洗涤和干燥,以去除任何残留的水分。
干燥的碳酸钙晶体然后经历一个称为研磨的过程。这涉及将晶体研磨成具有特定粒径分布的细粉。研磨后的粉末被包装好,准备分销。
重质碳酸钙的生产需要对各种参数进行仔细控制,如石灰石的质量、碳化条件和研磨过程。这些参数会影响最终产品的性质,如粒径、亮度和化学纯度等。
