I. Coal Mining Scraper Conveyor
1. Overview
Coal Mining Scraper Conveyor is a kind of conveying equipment used for transporting coal, ore and other bulk materials in coal mine, usually used in horizontal or inclined conveying environment. It advances the materials along the conveyor chain through the scraper to realize the continuous conveying of materials.
2. Structure
Conveyor belt and scraper: the knife scraper is fixed on the chain, and there is a certain interval between each scraper to form a coherent material transportation surface.
Frame: made of steel structure, supporting the whole conveying system.
Chain: supports the movement of the scrapers and is usually made of strong alloy material to resist wear.
Drive unit: consists of an electric motor and reducer to provide the necessary power.
Tensioning device: Keeps the chain properly tensioned and prevents it from slackening.
3. Working Principle
The scraper of the Coal Mining Scraper Conveyor moves on the track through the chain. The electric motor drives the chain through the reducer and the scraper pushes the material forward with the movement of the chain. The material is lifted by the scraper and transported to the set target position.
4. Advantages and disadvantages
Advantages.
High efficiency of continuous conveying, suitable for large-scale coal transportation.
Can work in complex environment, including inclined and short distance transportation.
Simple structure and easy maintenance.
Disadvantages.
Prone to certain effects on material adhesion and abrasion, which may lead to wear of scraper and chain.
Easy to block the Coal Mining Scraper Conveyor, especially coal with high moisture content or high viscosity.
5. Precautions for use
Operator training: must be professionally trained to understand the operating procedures of the equipment.
Load monitoring: overload operation is strictly prohibited to reduce equipment failure and wear.
Regular Maintenance: Clean up the residues and check the wear and tear of the chain and scraper regularly.
Safety observation: Be alert to the abnormal noise of the equipment when operating, and deal with the problems in operation in time.
Coal Conveyor
1. Overview
Coal Conveyor is the equipment specially used in coal mines, power plants, coal terminals and other places for coal and other bulk materials conveying, which can be belt conveyor, chain conveyor and other types. Its main function is to transport the mined coal from the mining point to the place of unloading.
2. Structure
Conveyor belt: it is usually a belt made of rubber, PVC and other materials with good abrasion resistance and tear resistance.
Roller: including driving roller and follower roller, the driving device of belt conveyor is usually placed in the position of driving roller.
Frame: supports the conveyor belt and roller, usually adopts steel structure.
Tensioning device: used to adjust the tension of conveyor belt to ensure its normal operation.
Driving device: motor, reducer and other related equipment to provide the necessary power for the conveyor.
3. Working principle
Coal Conveyor drives the conveyor belt to rotate through the driving device, coal is placed on the conveyor belt and is continuously transported to the designated place with the movement of the belt. The material moves forward by gravity during the downward transmission to achieve smooth transportation.
4. Advantages and Disadvantages
Advantages.
Long conveying distance, suitable for large-scale coal transportation.
Smooth running and low noise.
Adaptable to different production processes and flexible.
Disadvantages.
For high humidity and abrasive materials, it is easy to cause damage to the conveyor belt.
Regular maintenance is required, such as replacing the conveyor belt and checking the rollers.
5. Precautions for use
Load control: Be careful not to exceed the rated load of the conveyor.
Daily Inspection: Regularly inspect the conveyor belt, rollers and other key components, and deal with any problems promptly.
Material monitoring: Monitor the status of materials on the conveyor belt to avoid equipment malfunction due to material blockage.
Safety Measures: Ensure the surrounding environment is neat and clean to avoid potential safety hazards.
Conclusion
Coal Mining Scraper Conveyor and Coal Conveyor have their own characteristics and applicable scenarios. In the process of coal mine production and coal transportation, both devices help to improve transportation efficiency and safety. In view of the characteristics of different equipment in operation, operators need to pay attention to the condition of the equipment at all times, strictly abide by the operating specifications, and carry out the necessary maintenance to ensure the normal operation of the coal supply system.
