YA、YK型圆振动筛 Circular vibrating screen

一、用途

YA型圆振动筛主要适用于煤炭、冶金、矿山、发电、建材工业、水利工程、轻工和化工等行业。对煤、矿石、焦炭等散状物料分级的一种高效率筛分机械。

二、工作原理与结构特征

该振动筛的运动由电机通过三角胶带驱动具有偏心质量的振动器，而使筛箱产生振动，筛箱的运动轨迹为圆形。

该振动筛由筛箱、振动器、弹簧减振装置和支承底架等组成。筛箱采用先进的环槽铆钉联接，组成框架式结构。振动器采用偏心轴加偏心块式。弹簧减振装置采用钢制螺旋弹簧。

1.Use

YA Drum Vibrating Screen is primarily applied in coal, metallurgical, power generation, building material, water conservancy, light and chemical industries and other industries and a highly efficient screening machine to classify coal, ore, coke and other bulk materials. 

2.Working Philosophy and Structural Property 

The screen is operated by electric motor to drive vibrator with eccentric mass via delta belt, allowing screen box to vibrate, with the motional orbit of the screen box being circular.

The screen is composed of screen box, vibrator, spring damping device, supporting underframe and others, as shown in Fig.1. The screen box uses the advanced ring groove rivet for connection and is of frame structure.

The vibrator adopts eccentric shaft and eccentric block and the spring damping device uses steel spiral spring.
