圆筒筛

整机组成Complete Machine Composition

圆筒筛根据驱动形式分为自驱式和挂靠式

自驱式-----是指筛子本身具有驱动力，具有完整的使用功能和机器定义特性。

挂靠式-----是指筛子本身不具备驱动力，挂靠相关设备，由相关设备提供运行动力，具有完整的使用功能特性。

主要由机架、筛芯、轴承、联轴器、电机减速器、分料斗、防溅盖组成。筛芯装置由轴承支撑安装于机架上，电动机经减速机与滚筒装置通过联轴器连接在一起，驱动筛芯装置绕其轴线转动。

物料进入滚筒装置后，由于滚筒装置的转动，使筛面上的物料跳汰与滚动。再者，筛芯工作面安装了橡胶螺旋导流板，使得物料在跳汰时还做轴向运动，筛上分级物料（筛上产品）经滚筒内橡胶螺旋导流板导出，进入前集料斗；经筛芯筛网排出的物料（筛下产品）进入后集料斗。

The trommel can be divided into self-driven and hanging types based on their drive forms.

Self-driven: This refers to a screen that possesses its own driving force, complete functionality, and the defining characteristics of a machine.

Hanging: This refers to a screen that does not have its own driving force but relies on a related piece of equipment to provide the operational power, while still maintaining complete functionality.

It is mainly composed of a frame, screen core, bearings, couplings, motor red

ucer, material distributors, and splash guards. The screen core unit is supported and installed on the frame by bearings, and the motor is connected to the drum unit through a coupling via the reducer, driving the screen core unit to rotate around its axis.

After the material enters the drum unit, it is jigged and rolled on the screen surface due to the rotation of the drum unit. Furthermore, the working face of the screen core is equipped with rubber spiral deflectors, enabling the material to move axially during jigging. The graded material on the screen (oversize product) is guided out by the rubber spiral deflectors inside the drum and enters the front material collector; while the material discharged through the screen mesh of the screen core (undersize product) enters the rear material collector.
