用于焙烧包衣球的焙烧系统
摘要：
一种用于焙烧包衣球的焙烧系统，由鼓风机、换热器、调压器和炉体四部分组成，炉体主要由上气封段、焙烧氧化段、过渡段和下气封段组成。经过鼓风机的压缩空气分别通过热风布风器从焙烧氧化段下部，以及经过调压器、冷风布风器，从焙烧氧化段中部进入炉体，包衣球从上气封段顶部加入，与空气接触进行固化，然后从下气封段底部排出炉体。这种系统可以有效的解决现有技术中无法向被焙烧物料内部供氧气的问题。
摘要（英）：

A calcining system for the coated spheres is composed of blower, heat exchanger, pressure regulator and furnace body consisting of upper air-seal segment, calcine oxidizing segment, transition segment and lower air-seal segment. The compressed air comes in furnace body from the lower and middle parts of said calcine oxidizing segment and the coated spheres come in furnace from said upper air-sealsegment for contacting with air to solidifying them. Its advantage is to supply oxygen to the coated spheres to be calcined.
