What factors affect the conveying capacity of the scraper conveyor machine?
1. Equipment factors
Scraper chain speed: The faster the scraper chain runs, the greater the amount of material that can be transported per unit time. However, too high a speed may also cause problems such as material spillage and increased equipment wear.
Scraper spacing: The scraper spacing determines the amount of material that can be pushed each time. If the spacing is too small, the material may accumulate between the scrapers, affecting the conveying efficiency; if the spacing is too large, some materials may not be pushed in time.
Trough width and depth: A larger trough size can hold more material, thereby increasing conveying capacity. However, the trough size is also limited by installation space and equipment cost.
Scraper shape and size: Scrapers of different shapes and sizes have different pushing effects on materials. Reasonable scraper design can improve conveying efficiency and reduce material residue.
2. Material characteristics factors
Material size and shape: Larger particles or irregularly shaped materials may cause blockage during conveying and affect conveying capacity, while smaller particles and uniformly shaped materials are easier to convey.
Bulk density of materials: Materials with high bulk density have a higher weight per unit volume and may require greater thrust to transport, thus affecting the conveying capacity.
Material fluidity: Materials with good fluidity are easily pushed by the scraper and have a relatively high conveying capacity; while materials with high viscosity and poor fluidity tend to adhere to the machine trough and scraper, reducing the conveying efficiency.
Material humidity: Materials with excessive humidity may stick together, increase conveying resistance, and reduce conveying capacity. At the same time, humidity may also cause equipment corrosion and increased wear.
3. Operating environment factors
Installation angle: The scraper conveyor can be installed horizontally, inclined or vertically. The greater the inclination angle, the greater the gravity component of the material, the greater the difficulty of conveying, and the lower the conveying capacity.
Working temperature: In a high temperature environment, the parts of the equipment may expand thermally, affecting the operating accuracy and reliability of the equipment, thereby reducing the conveying capacity. In a low temperature environment, the material may freeze, which will also affect the conveying effect.
Dust and impurities: If there is a lot of dust and impurities in the conveying environment, they may enter the equipment, increase the wear and failure risk of the equipment, and affect the conveying capacity.
4. Maintenance and management factors
Equipment maintenance: Regular maintenance of the scraper conveyor, such as cleaning the accumulated material in the machine trough, checking the wear of the scraper chain, adjusting the tensioning device, etc., can ensure that the equipment is in good operating condition and improve the conveying capacity.
Operator skill level: The operator's familiarity with the equipment and operating skill level will also affect the conveying capacity. Correct operating methods and timely troubleshooting can ensure the stable operation of the equipment and improve the conveying efficiency.
