前言侧鼓跳汰机作为主要选煤设备已被广泛采用,它在技术和经济方面有许多优点,例如处理能力大、运转成本低、使用寿命长。然而,燃料煤需求量的增加,需要一种处理能力大和高效率的侧鼓跳汰机。为满足这种需要,日本对跳汰机模型和实用跳汰机进行了理论和实验室研究。 Introduction Side drum jig has been widely used as the main coal preparation equipment. It has many technical and economic advantages, such as large processing capacity, low running cost and long service life. However, the increased demand for fuel coal requires a side drum jig that has a large capacity and high efficiency. To meet this need, Japan conducted theoretical and laboratory studies on jig models and practical jig machines.
