MoS_2的焙烧可以在旋转式焙烧炉、窄轴式多膛焙烧炉和沸腾焙烧炉里进行。从理论上讲,使用沸腾炉更为经济。但是,对放热反应时的温度和 MoS_2的焙烧温度以及 MoO_3的提纯温度等因素的控制还存在许多困难,这使得采用多膛焙烧炉更加切合实际。事实上,世界上多数国家都使用窄轴式多膛焙烧炉。这种焙烧炉的优点是:效率高、焙烧过程控制严密,这些优点都借助了水套作用。使用这种焙烧炉焙烧钼精矿所茯产品质量也较高。
MoS_2 roasting can be carried out in a rotary roaster, a narrow-axis multi-chamber roaster, and a roasting furnace. In theory, using a boiling furnace is more economical. However, there are still many difficulties in controlling the exothermic reaction temperature, the calcination temperature of MoS 2 and the purification temperature of MoO 3, which make the use of multi-hearth calciners more practical. In fact, most countries in the world use narrow axis multi-chamber calciners. The advantages of this roaster are: high efficiency, strict control of the roasting process, all of which rely on the water jacket effect. The use of roaster roasted molybdenum concentrate products of the higher quality.
