碳酸钙干燥设备概况与发展

General situation and development on drying equipment of calcium carbonate

对碳酸钙(轻钙,重钙,纳米钙,专用钙等)的干燥及其有关设备的现状和发展作了回顾,并就轻钙、重钙、纳米钙等干燥效率的提高、设备的改进以及组合干燥的应用实际效果作了阐述。

Calcium carbonate is an important traditional chemical product of our country; it is the raw material of many kinds of industry such as rubber, plastic, coating, foodstuff, medication and paper making. As the developing of national economy, the requirement to the quality and yield of deposited Calcium carbonate, heavy Calcium carbonate and nanometer Calcium carbonate is improving. The drying operation needs to be more green, energy saving, more mechanized and more automated. Therefore, it is necessary to survey the actuality and development of drying technology and apparatus in this paper. We also expound how to increase the drying efficiency, how to improve on the equipment, and the practical effect of combination drying technology.
