What is the role of the gravel on the tracks?
1. Relatively narrow width between the rails. After the covered Crushed Stone roadbed can be widened, and the locomotive tremendous pressure by rail, sleepers spread to the ballast, and then evenly distributed over the embankment, subgrade pressure will drop. The uniform dispersion of gravity from the rail to the ground, so as to ensure the…
Fracture cavity type of high performance and high successful combination of crushing frequency, makes the new type of cone crusher (high efficiency hydraulic cone crusher) processing power is greatly increased, and as a result of the principle of laminating crushing, crushing machine is cubic structure more, largely reduces the needle flake material. New type of…
1. Use broken pebble the role of the physical properties of concrete Pebble in the process of formation, the handling of water constantly in the process of extrusion, friction, lost the edges, surface is smooth, so it’s less friction force on the ash concrete sand, we used the cobble crushing production of broken pebble of…
