Ballast Stone Crushing Track ballast stone belong to the construction using mine broken stone or pebble broken stone, also known as building stones, used for highway, railroad ballast stone, airport runway special stones, and mostly are hard rock such as basalt with specifications in the 3--7centimeters, so broken materials hardness is relatively large. Jaw Crusher is preferred in the production of ballast stone , especially Jiangsu Zhongbo Machinery produced JC European version of jaw crusher ( referred to as the European Jaw Crusher). Track Ballast Jaw Crusher Jiangsu Zhongbo Heavy Machinery Co., Ltd. jaw crusher can be used in metallurgy, mining, chemical, cement, construction, ceramics and refractories industries as well as the broken and fine crushing various ores and rocks and other hard. The series of crusher is suitable for crushing ore, rock, slag with strength higher than that of 280Mpa. For railroad ballast stone fragmentation, the European jaw crusher has its unique advancement: 1. using the world class manufacturing process and the most high-end production materials. 2. movable jaw plate is assembly with high quality castings, heavy eccentric shaft adopts the forging processing, so that the machine has excellent reliability, more durable. 3. the bearing seat adopts the integral cast steel structure to guarantee the perfect fitting, greatly enhance the bearing radial strength. 4. finite analysis technology, make the machine more strength. 5. crushing cavity using symmetric" V" shaped structure, so that the actual material inlet width and nominal inlet width are consistent. 6. provided with a wedge block adjusting device of discharge opening, compared with the old shim adjustment, it is more simple, safe and efficient. 7. the series of all the machines are using greater and more durable eccentric shaft than the same specifications crusher . Its higher load carrying capacity and effective labyrinth seal greatly prolong the service life of bearing. 8. adoption of the the latest toothed plate, increases the effective length of the jaw plate, improve the yield. To sum up, compared to the traditional two levels jaw crusher, the European version of jaw crusher either service life or failure rate, repair rate, it reflects the incomparable superiority. The European version of the JC series crusher is one of the world's most popular jaw crusher. It uses the international most advanced crushing technology and manufacturing level. It is the preferred product with high efficiency for crushing hard, strong abrasive materials.
