Ballast stone screen equipment

Good quality track ballast is made of crushed natural rock with particles between 28 mm and 50 mm in diameter. And angular stones are preferable to naturally rounded ones, as angular stones interlock with each other, inhibiting track movement. Soft materials such as limestone are not particularly suitable, as they tend to degrade under load when wet, causing deterioration of the line; granite, although expensive, is one of the best materials in this regard.

 

In order to get the eligible ballast stones for highway, railway and road building, quarry mining usually use the complete ballast crushing and screening plant. In ballast crushing and screening plant, stones firstly enter into jaw crusher for primary crushing, then through belt conveyor evenly enter into impact crusher or cone crusher for fine crushing. Finally, through vsi crusher stones mainly are cubic in shape. Vibrating screen is used as screening machine to screen out the different size of ballast. The ballast that are unqualified return to the crushing plant for crushing again.
