筛分机械是造块工艺不可缺少的设备之一,特别是近年来烧结矿整粒技术的发展,筛分机械在造块工艺中的应用更加广泛。惯性振动筛(本文简称振动筛)具有工艺效果好,结构简单,操作维修方便等优点,因此现代造块工艺所应用的筛分机械几乎都是振动筛。共振筛由于结构复杂、机重大、难调整,特别是筛上负荷变化时,难于 Screening machinery is one of the indispensable equipment in the process of block making. Especially in recent years, the development of sinter whole grain technology has made the application of screening machinery in the process of making block more widely. Inertial vibrating screen (hereinafter referred to as vibrating screen) has the advantages of good process effect, simple structure, convenient operation and maintenance, etc. Therefore, most of the screening machines used in modern building process are vibrating screens. Resonance sieve due to the complex structure, heavy machine, difficult to adjust, especially when the load on the screen changes, it is difficult
