Jing Gong Railway screening machine
The crushed stone in the sleeper box on the railway subgrade is called ballast stone. The main functions of ballast stone are as follows:
1. Bear the pressure transmitted by the sleeper and distribute the pressure evenly on the subgrade.
2. Fix the sleeper position and maintain the correct line shape and slope of the track.
3. Drain the rainwater around and below the sleeper to prevent the soil of subgrade from deformation due to wet and soft.
4. Increase the elastic force of the track to make the rail quickly return to the original correct position after being rolled by the train.
With the operation of the railway and the passage of time, a lot of dust, soil and weeds will be produced in the joint of railway ballast stone. If the cleaning is not carried out regularly, the ballast stone will be affected to play its role. The traditional cleaning method is manual screening, and shovels or nine rakes are used to shovel the ballast stone onto the drying line, and the vibration is cleaned by manual operation. The cleaned ballast stone is then returned to the cleaned sleeper box. The ballast stone will be poured back into the sleeper box every time the screen is cleaned, which results in labor waste and low work efficiency.
Railway screening machine is a kind of railway maintenance equipment which is widely used in railway maintenance. It mainly absorbs and transmits the dirt such as crushed stone slag and soil in the line. The level of screening technology and mechanical quality are related to the process effect, production efficiency and energy saving. Railway screening machine with its simple structure, powerful processing capacity and reliable working efficiency has a comparative advantage in most screening equipment. In recent years, the company's research on Railway screening has been strengthened and many parameters have been strengthened.
Screening machinery is widely used in mining, metallurgy, chemical industry, building materials industry, road construction industry and environmental sanitation industry. It is also widely used in railway maintenance. It is used for screening, grading, washing, demineralization and dehydration of materials. Screening machine has a history of more than 100 years in industry. In this process, from manual screen to mechanical shaking screen, fast shaking screen, resonance screen, vibrating screen and so on. Due to its simple structure, stable performance and convenient maintenance, the screening machine has been widely used. In recent years, it has been greatly developed and improved in terms of varieties and specifications, structural
strength, or technical performance.
