In this study a series of single particle crushing tests were performed on 700 ballast particles to specify the numbers and sizes of ballast particles crushed after ballast breakage Four classification algorithms support vector machine SVM backpropagation neural network BPNN random forest RF and CatBoost CB were used to predict
Analysis of the application of crushed stone ballast cleaning technology taking into account a set of technical operational features of the repair site technical characteristics of track machines for deep cleaning of crushed stone ballast as well as technological and production requirements for various types of the path repair showed the
Deiros et al [4] analyzed the influence of ballast crushing caused by tamping on track performance by using discrete element method Feng B [5] used COSMOSMotion software and ANSYS to analyze the tamping mechanism Wang ZB et al [8] established a refined coupling model of tamping machine and ballast bed by using EDEM to investigate the
Some researchers have conducted extensive investigations using large triaxial tests [2] [7] chamber tests [8] [9] large size straight shear tests [10] [11] and impact tests [12] [13] to explored the comprehensive crushing behavior of ballast aggregates under varying loading conditions This type of test generally relies on analyzing the alteration in ballast aggregate
It is known that with an increase of the passed tonnage the ballast layer tends to become contaminated both by the products of its own crushing and by the external weeds which rapidly leads to
The ballast cleaning machine 1 [2] contains a frame 2 supported by running gears 3 Conveyors 4 and 5 with plows 6 and 7 are fixed on the frame 2 and a bar chain 8 is fixed frame 2 of the crushing machine the upper ends of the springs are fixed to the corresponding rod 11 12 and the opposite ones rest against the lower end of the

A ballast crusher machine is designed to crush stones into smaller manageable sizes typically for use in railway ballast road construction and building foundations German stone crushing
Microscopic properties of granular materials typically exhibit significant heterogeneity Realistic particle crushing simulation in granular materials requires the use of model that incorporate the spatial heterogeneity of its microscopic properties This study introduces a novel approach the Random Field Theory Discrete Element Method RFT DEM
Railroad ballast Crushed limestone being strong and angular is a great choice for railroad ballast Concrete production Crushed limestone produces stronger less expensive concrete Asphalt production Crushed limestone can be used as aggregate for mixing hot mix asphalt Wet limestone can clog crushing machines and cause downtime
The ballast is usually the super granite which has strong rigidity As for its crushing technology very often the jaw crusher would be used at the first stage of crushing and cone crusher would be used at the second or third stage 100 150tph Crushing Line; 150 180tph Crushing Line; 350 400tph Crushing Line
