上青矿隶属于通钢集团板石矿业有限责任公司,是公司主要的铁矿石原料生产基地。其溜破系统采用了悬挂式异步振动给料机,该异步振动给料机由YJZ-22.4型激振器、工作机体及悬挂装置三部分组成。1悬挂式异步振动给料机的安装及工作状况异步振动给料机通过悬挂装置(由悬挂钢丝绳、上固定板和下固定板等组成)安装在硐室顶棚上(见图1)。当激振器电源接通时,上下两台激振器同时振动,上激振器逆时针旋转振动,下激振器顺时针旋转振动,上下两台激振器的偏心块偏心度都调整为80%,提供恒定的惯性激振力并通过激振器座传递至给料机工作机体,驱使其沿激振力方向做复杂轨迹的往复运动,完成给料、输送等工作。
The green ore belongs to Tonghua Group Slate Stone Mining Co., Ltd., is the company’s main iron ore raw material production base. The slip-breaking system uses hanging asynchronous vibrating feeder, the asynchronous vibrating feeder by YJZ-22.4-type exciter, working body and suspension device consists of three parts. 1 hanging asynchronous vibrating feeder installation and working conditions Asynchronous vibrating feeder through the suspension device (by hanging wire rope, the upper fixed plate and the lower fixed plate, etc.) installed in the roof of the chamber (see Figure 1). When the exciter power is turned on, the two upper and lower vibration exciters vibrate simultaneously, the upper vibration exciter rotates counterclockwise, the lower vibration exciter rotates clockwise, and the eccentric eccentricity of the upper and lower two exciters are adjusted to 80%, to provide a constant inertial excitation force and delivered to the feeder through the exciter seat working body, driving it along the direction of excitation force to do complex trajectory reciprocating motion, to complete the feeding, conveying and other work.
