Selection Guide for Core Components of En - Masse Conveyor
In the field of bulk material handling, En-masse conveyors have gained widespread application across various industries such as mining, chemical, grain, and building materials, thanks to their advantages of good airtightness, small footprint, and stable conveying. However, many enterprises often encounter issues such as low conveying efficiency, rapid component wear, and frequent failures during use. Tracing back to the root cause, these problems are often due to improper selection of core components.
This article will delve into the selection logic and practical points for the four core components of En-masse conveyors, helping enterprises avoid common pitfalls in component selection and achieve efficient and stable operation of the equipment.
Ⅰ. Preliminary Considerations: Understanding Material Characteristics and Working Conditions
The prerequisite for selecting core components is a comprehensive understanding of material characteristics and actual working conditions, which directly determine the material, structure, and parameter matching of the components. The following key information should be focused on:
Material Characteristics: These include material density, particle size, moisture content, viscosity, abrasiveness, and corrosiveness. For example, wet coal slime is a high-viscosity material, quartz sand is highly abrasive, and chemical raw materials may be highly corrosive.
Working Conditions: Clarify the conveying capacity, conveying distance, conveying angle, as well as the temperature and humidity of the equipment operating environment. For instance, in high-temperature conditions, the heat resistance of components needs to be considered, and in outdoor environments, rust and corrosion prevention are essential.
Ⅱ. Scraper: The “Direct Handler” for Conveying Materials
The material selection should match the material properties. For abrasive materials, high-manganese steel or wear-resistant alloy can be chosen, while for corrosive materials, stainless steel is preferred.
The structural form should be determined based on conveying requirements. For ordinary materials, T-shaped scrapers are suitable;for sticky materials, U-shaped scrapers are appropriate;and for large-sized materials, heavy-duty scrapers can be selected.
Ⅲ. Chain: The “Power Link” for Equipment Operation
Common types include roller chain, bushing chain, and plate chain. For heavy-duty conditions, plate chain is recommended, while for high-speed conveying, roller chain is preferred.
The material should balance strength and corrosion resistance. Carbon steel chains are suitable for dry environments, while stainless steel chains should be used in humid or corrosive conditions.
Ⅳ. Trough: The “Load-Bearing Channel” for Material Conveying
The material should be selected based on the material characteristics. For ordinary materials, Q235 steel plate can be used, while for wear-resistant or corrosive materials, wear-resistant steel or stainless steel should be adopted.
The cross-sectional form can be rectangular or trapezoidal. For horizontal conveying, a rectangular shape is commonly used, while for inclined conveying, a trapezoidal shape is recommended to prevent material from sliding down.
Ⅴ. Drive Device: The “Power Core” for Equipment Operation
The motor power should be calculated based on the conveying capacity, conveying distance, and material resistance to avoid insufficient power or waste.
For the reducer type, priority should be given to hard-toothed reducers, which have strong load-bearing capacity and high efficiency, making them suitable for heavy-duty continuous operation conditions.
Key Conclusion: The stable operation and efficient conveying of En-masse conveyors largely depend on the scientific selection of the four core components -- scrapers, chains, troughs, and drive units -- which should be precisely matched according to material characteristics and working conditions.
