What are the advantages of LG type chain feeder and what is it suitable for transporting materials?

一.Explanation of the working principle of LG chain feeder

The working principle of LG type chain feeder is based on chain drive. When the driving device starts, the driving drum starts to rotate, and by virtue of the friction between it and the chain, it drives the chain to do circular movement. On the chain, the scraper is fixed at intervals, and with the movement of the chain, the scraper also runs synchronously. The material in the silo falls into the trough under the effect of gravity, and contacts with the scraper. Scraper in the process of movement, promote the material along the trough to the direction of the outlet. When the material reaches the discharge port, due to the loss of the support of the scraper, it will be discharged from the discharge port under the action of gravity, so as to realise the continuous conveying of the material.

In the whole working process, the stable operation of the driving device is the key. The driving device usually consists of motor and reducer, etc. The motor provides the power and the reducer adjusts the rotational speed according to the actual demand to ensure that the running speed of the chain is appropriate to meet the requirements of conveying different materials. By adjusting the rotational speed of the motor, flexible control of the feeding volume can also be achieved.

二.LG type chain feeder is suitable for which materials?

1.coal industry

(1)Raw Coal Conveying Advantages

In the coal industry, the LG type chain feeder shows excellent performance and becomes the ideal choice for the raw coal conveying process. Its perfect co-operation with the jigger brings many advantages to the coal washing process. In practice, the LG chain feeder can feed uniformly along the full width of the jigger, which ensures the even distribution of raw coal in the jigger. This feature is crucial to the washing effect of the jigger, as uniform feeding enables the raw coal to fully contact with water and air in the jigger for more accurate stratification and sorting.

Adjusting the feed volume is also a highlight of the LG chain feeder. In the process of coal washing, the quality of the incoming coal directly affects the parameter settings of the washing process, and the LG chain feeder can easily adjust the size of the feeding volume according to the changes in the quality of the incoming coal. When the coal quality is good, the feeding quantity can be increased appropriately to improve the production efficiency; while when the coal quality is poor, the feeding quantity can be reduced to ensure the washing effect. This flexible adjustment ability makes the coal washing process more efficient and stable.

(2)Adaptability to different particle size of coal

The particle size of coal is widely distributed, from fine coal dust to large lumps of raw coal, LG type chain feeder can show good adaptability in conveying coal of different particle sizes. For the mixed loose raw coal with particle size between 0 – 100 mm, it can convey steadily.

When conveying smaller size coal powder, due to the better fluidity of the coal powder, it is easy to leak and fly during the conveying process. the trough of the LG type chain feeder adopts the sealing design, which can effectively prevent the leakage of the coal powder. At the same time, the smooth movement of the chain and scraper will not cause too much disturbance to the coal powder, so as to avoid the flying of coal powder. The design of the scraper is also well adapted to the characteristics of the coal powder, which can be smoothly transported to the discharge port.

For large size lump coal, LG type chain feeder can also cope with it freely. Its chain and scraper are made of high-strength materials with sufficient strength and wear resistance to withstand the weight and impact of large lumps of coal. During the conveying process, the scraper can effectively push the large pieces of coal forward without jamming or clogging. Moreover, the driving device of LG type chain feeder has a large torque, which can ensure the stable operation of the chain when conveying large pieces of coal, and there will be no slippage or stagnation.

2.Cement field

(1)Raw material conveying guarantee

In the process of cement production, the stable supply of raw materials is the key to ensure the continuity of production, LG type chain feeder plays an important role in this link, it can efficiently transport limestone, clay, iron ore and other raw materials for cement, limestone is one of the main raw materials for cement production, and its dosage accounts for a large proportion of the raw materials.

Limestone is one of the main raw materials for cement production, and its dosage accounts for a relatively large proportion of cement raw materials. the LG chain feeder can stably transport large limestone from the storage silo to the crusher, providing sufficient raw materials for the subsequent grinding process. Its sturdy chain and scraper structure can withstand the weight and impact of limestone, ensuring a smooth conveying process.

Clay, as an auxiliary raw material for cement production, has a certain degree of viscosity and humidity, and the scraper design of LG chain feeder can effectively prevent clay from adhering to the chute and scraper during conveying to ensure smooth conveying of materials. At the same time, the sealed chute structure can also avoid the evaporation of water in the clay and maintain the original characteristics of the material. In some small cement factories, due to the limited space and equipment conditions, the adaptability of the feeding equipment is more demanding, LG type chain feeder is small in size and easy to install, it can be well adapted to the production environment of these small cement factories, providing reliable raw material conveying service.

(2)Consideration of finished cement conveying

When the cement production is completed, LG type chain feeder takes the characteristics of materials and the requirements of environmental protection into full consideration when conveying the finished cement.

Finished cement is usually fine powder, which is easy to generate dust during conveying, causing material loss and environmental pollution.LG type chain feeder adopts trough and chain structure with good sealing performance, which can effectively reduce the leakage of dust. At the discharge port, it can also be equipped with special dust removal device to further reduce the emission of dust. In some areas with high requirements for environmental protection, cement factories use LG chain feeder to convey finished cement, and with efficient dust removal equipment, the dust concentration in the workshop is greatly reduced to meet the requirements of environmental protection standards, creating a good working environment for the employees.

In addition, the LG type chain feeder can maintain a smooth running speed during conveying, reducing the impact and friction on the finished cement, thus effectively avoiding the breakage of materials. This is of great significance to ensure the quality and performance of cement. In the storage and packaging of cement, the cement needs to be transported from the storage to the packaging machine, LG type chain feeder can accurately control the feeding quantity, ensure the normal operation of the packaging machine, and improve the packaging efficiency and quality.

3.Metallurgical field

(1)Ore conveying performance

Iron ore is the main raw material for iron and steel production, and its conveying efficiency and quality directly affect the output and quality of iron and steel.LG type chain feeder can stably convey iron ore from mining site or raw material dump to beneficiation plant for processing. Its chain and scraper have high strength and wear resistance and can withstand the weight of iron ore and the friction of sharp edges. During the conveying process, even if it encounters large pieces of iron ore, it can be smoothly conveyed to the designated position without jamming or clogging.

For other non-ferrous metal ores, such as copper ore, lead-zinc ore, etc., these ores have different physical properties and chemical compositions, but the LG type chain feeder can meet the conveying requirements of different ores by virtue of its good adaptability. Its sealed structure can effectively prevent dust from being generated during the conveying process, thus reducing pollution to the environment. At the same time, its smooth running characteristics can also reduce the crushing and loss of ore and improve the utilisation of resources.

4.Chemical industry

(1)Conveying various kinds of chemical raw materials

In the chemical industry, LG type chain feeder can safely and stably convey all kinds of chemical raw materials. In the process of salt conveying, take sodium chloride, potassium chloride and other common salts as an example, these salts usually have a granular form, and in a certain humidity environment may appear caking phenomenon, LG type chain feeder with its stable chain drive and reasonable scraper design, can effectively transport the salts from the storage container to the reaction kettle or other processing equipment. Even when encountering lumpy salts, its sturdy scraper can break up the lumpy materials and transport them smoothly, ensuring the continuity of the production process.

For powder chemical raw materials, such as calcium carbonate, talcum powder, etc., which have the characteristics of fine particle size and easy to fly, the sealed trough and stable running chain of LG type chain feeder can effectively prevent the powder from leaking and flying during conveying, which reduces the loss of materials and pollution to the environment.

三.Unsuitable materials and precautions

1.Oversized or overweight materials

Although LG type chain feeder has strong conveying capacity, it is not suitable for conveying oversized or overweight materials. In terms of size, when the size of material exceeds the width and height of the trough, the material can not enter the trough smoothly, and even if it barely enters, it will be stuck in the conveying process, resulting in equipment failure.

From the weight point of view, the chain, scraper and driving device of LG type chain feeder have their own load limit. If the conveyed material is overweight, the chain may break due to excessive tension and the scraper may be bent or damaged. The drive unit needs to provide more power to drive the overweight material, which may cause the motor to be overloaded and burn out the motor.

2.Highly viscous and easily lumped materials

High viscous and easily lumped materials will bring many problems when conveyed by LG type chain feeder. For highly viscous materials, such as adhesives in some chemical raw materials, high viscosity polymers, etc., they are easy to adhere to the surface of the trough and scraper. In the process of conveying, with the continuous adhesion of materials, the effective conveying area of the trough and scraper will gradually reduce, resulting in reduced conveying efficiency. A large amount of material adhesion may also increase the scraper’s operating resistance, increase the load of the drive device, or even lead to equipment shutdown.

Materials that are prone to caking, such as damp cement and salts, are prone to forming lumps during conveying. These lumps may get stuck between the chain and the sprocket, or block the outlet of the trough, affecting the normal conveying of materials. Lumpy materials will also cause additional impact and wear on the chain and scraper, shortening the service life of the equipment.
