滚简筛的基本工作原理是:颗粒物随筛简旋转至一定高度，由于重力作用被抛酒坠落，通过筛网过滤筛分，本滚筒筛为无轴式传动，动力端采用电机带动齿轮传动，内测拖轮及另一端托轮将简体支撑在机架上，它具有结构简便、操作简单，更换筛网可在一定范国内获取不同粒度的物料等特点，该机适用不同颗粒物料的分级筛选。

The basic working principle of a drum screen is that particles rotate with the screen cylinderto a certain height, are thrown and fall due to gravity, and are filtered and screened througha sieve. This drum screen is a shaftless transmission, and the power end is driven by a motorto drive gears. The inner measuring trailer and the other end supporting wheel support thecylinder on the frame. lt has the characteristics of simple structure, simple operation, andthe ability to obtain materials of different particle sizes within a certain range by replacingthe sieve. This machine is suitable for grading and screening materials of different particlesizes.
