Ballast crushing plant
Gulin® Ballast crusher is used for crushing stones into small pieces to produce railway ballast in Stone quarry plant. There are several types of ballast crushers used in ballast crushing and screening plant.
Ballast crushing plant
Ballast Jaw crusher is the coarse crusher machine used in ballast coarse crushing and process plant. It has found its extensive use in the mining, metallurgical industry, construction, road and railway building, conversancy, chemistry, etc.
Mobile ballast crusher is the most convenient crushing machine used in ballast crushing plant. Portable series mobile crushing plant is a new type of crushing equipment, which expands the concept field in coarse crushing and fine crushing. Based on the client’s requirements, Portable series mobile crushing plant take the problem like the crushing place, surroundings brought as the priority work.
Ballast Cone crusher is the fine ballast crushing machinery. There are four type of cone crushers: spring cone crusher, CS series cone crusher, hydraulic cone crusher and hcs90 cone crusher. Gulin® cone crusher is usually found in ballast crushing and screening plant in India.
Ballast Screening machine
Ballast Screening machine
Screening machine used in ballast screening plant: Vibrating screen is used as screening machine in ballast crushing and screening plant to screen out the suitable ballast. Vibrating screen moves round with multi-layers and high efficiency. The vibrating screen can screen the materials into multiple levels products according to the different material grain size.
In the ballast crushing and screening plant, 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.
Ballast crushing process
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. The ballast crushing and screening process is as follows:
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 ballast crusher plant for crushing again.
