How is railway ballast produced?

If there is no ballast, the rails and sleepers are laid directly on the roadbed, and the roadbed may not be able to bear the weight of the train and sink downward. The gaps and texture between the crushed stones of the ballast play a good role in dispersing the huge pressure generated by the passing of the train, and evenly disperse the pressure to the foundation. The elasticity of the ballast can well disperse the vibration and noise of the train, making passengers more comfortable and protecting the roadbed.


The production, storage and loading of ballast are all completed in a dedicated storage and transportation base. The base is generally located in a location close to the railway freight station, which is convenient for production, loading and transportation, and maximizing efficiency.


The stone used to make ballast is natural stone. The raw stones that meet the requirements of hardness, wear resistance, water permeability and other indicators will be transported to the ballast production base after being mined, poured into the ballast production line for crushing.  https://www.lzzgmachine.com/service-parts/product-knowledge/how-is-railway-ballast-produced.html

Maintenance and storage method of vibrating screen motor and common troubleshooting

The service life of the vibration motor determines the operating life of the entire screen. Therefore, in the normal production, we must always pay attention to whether the working state of the vibrating screen equipment is normal, whether the vibrating motor is in good working condition, timely check and solve some small abnormalities and faults, and do a good job of cleaning and maintenance, because this can greatly increase the vibration screening. Machine and vibration motor life. dewatering screens supplier Maintenance storage precautions during vibrating screen motor operation The equipment can not be completely dust-free, but also has a harsh environment and dusty conditions. The vibration motor is airless and heat-cooled. It relies on natural cooling, so it must be specially maintained. The following is the maintenance content. 1. It is necessary to pay attention to whether the vibration is abnormal during the use process; 2. Always check if the bolts used in the m...

300t per hr chalcopyrite washing equipment

Chalcopyrite is a copper-iron sulfide mineral. It often contains trace amounts of gold and silver. Crystals are relatively rare and are tetrahedral-shaped, mostly irregular granular and dense massive aggregates, as well as kidney-shaped and grape-shaped aggregates. Copper yellow, often dark yellow or mottled. The streaks are black with a greenish tint. Chalcopyrite is a relatively common copper mineral, which can be formed in different environments, but it is mainly the product of hydrothermal action and contact metasomatism, and it can often form deposits of a certain scale. The origin is all over the world. In industry, it is the main raw material for copper smelting. In the field of gemology, it is rarely used alone, occasionally as a substitute for pyrite. In addition, it often participates in the composition of some colored stones, inkstones and jade. The high-efficiency spiral chalcopyrite washing machine is mainly used in the washing, grading, impurity removal, and the washing o...
