Coal Mining Scraper Conveyor and coal conveyor are very important equipments in coal mining industry, which are mainly used to transport the mined coal from the mining face to the ground or other handling locations. The following will introduce these two kinds of equipment in detail, including their working principle, main features, application areas and maintenance.
I. Coal Mining Scraper Conveyor
1. Working principle
Coal Mining Scraper Conveyor is a kind of continuous conveying equipment, which usually includes the following key parts:
Conveyor chain: made of high strength material, connecting the scraper, responsible for pushing the scraper forward.
Scraper: A shovel-shaped part fixed on the chain, used to scoop up the coal and push it forward.
Conveyor Chute: forming the closed conveyor road of chain and scraper, made of steel or other wear-resistant materials.
Motor and reducer: provide power for the whole system, drive the chain and scraper movement.
In the working process, the motor drives the reducer to rotate and drive the chain and scraper to move to transport the coal.
2. Main features
High carrying capacity: capable of carrying and transporting a large amount of coal, especially suitable for high-intensity working environment.
Strong abrasion resistance: made of abrasion-resistant materials, adapting to the harsh working environment in coal mines.
Strong continuity: it has the ability of continuous transportation, suitable for the transportation of large quantities of coal.
Low maintenance cost: the structure is relatively simple and easy to maintain, which reduces the downtime of the equipment.
3. Application Areas
Coal mining face: Transporting the mined coal from the mining face to the lifting point or distribution point.
Surface coal mine: used to transport coal and other ores in surface coal mine operation.
Second, coal conveyor
coal conveyor is a broader concept that encompasses a number of different types of conveyors capable of transporting coal and other bulk materials.
1. Principle of operation
The basic principle of operation of a coal conveyor is to transport coal from one place to another using a conveying mechanism such as a drive belt, chain or screw. Depending on the specific type, the working of coal conveyor can be categorized as:
Belt Conveyors: use one or more continuous conveyor belts to drive the coal through the conveyor system.
Scraper Conveyors: use scrapers to continuously propel the coal forward along a conveyor chute, as described earlier.
Screw conveyor: uses a screw conveyor to propel the coal through a closed pipe.
2. Main features
Wide range of application: able to adapt to the conveying needs of different materials, including coal, ore, sand and gravel.
High flexibility: the inclination and length of the conveying line can be adjusted as needed.
High degree of automation: modern coal conveyor is usually equipped with automatic control system, which can realize unattended operation.
Good reliability: high load and long time continuous operation are usually considered in the design to ensure high efficiency and stability of the equipment.
3. Application fields
Underground and surface transportation of coal mine: It is used to transport coal from the depth of the mine to the surface, or for secondary processing and storage on the surface.
Power plants: Commonly used in coal transportation system of coal power plants, conveying coal from receiving station to boiler.
Ports and logistics centers: widely used in coal loading and unloading, transportation and storage.
III. Maintenance and upkeep
Whether it is Coal Mining Scraper Conveyor or coal conveyor, it needs regular maintenance to ensure its normal operation:
1. Regular inspection
Regularly check the wear and tear of key parts such as chains, scrapers and conveyor belts.
Observe the running status of the motor and reducer to ensure their normal operation.
2. Lubrication maintenance
Regularly lubricate the moving parts to reduce friction and prolong service life.
3. Cleaning residue
After work is completed, clean coal or other residues on the conveyor in a timely manner to avoid accumulation leading to equipment failure.
4. Record maintenance
Record the content and working status of each maintenance for subsequent analysis and management.
Summarize
Coal Mining Scraper Conveyor and coal conveyor play a key role in the coal mining industry, and their efficient transportation capacity not only improves the production efficiency of coal mines, but also facilitates subsequent handling and utilization. Through reasonable use and regular maintenance, it can ensure the smooth and efficient operation of these equipments for a long time.
