LS-type screw conveyor diameter from 100mm ~ 1250mm, a total of twelve kinds of specifications, divided into single-drive and dual-drive two forms, single-drive screw maximum length of up to 40m (extra large 30m), dual drive screw Open shaft structure, the maximum length of up to 80m (extra large 60m), the length of the screw machine every 0.5m a file, according to the need to select the screw head bearing, tail bearing placed outside the shell to reduce the dust on the bearing chamber The intrusion improves the service life of the key parts of the screw machine. The middle crane bearing adopts rolling, sliding interchangeable two kinds of structure, the resistance is small, the sealing is strong, the wear resistance is good. Sliding bearing bearing with powder metallurgy, nylon and babbitt and other materials for users to choose according to different occasions. Hanging bearing machine outside the side of the oil cup, easy to focus on lubrication. The inlet and outlet positions are flexible and the electric outlet is added, which is convenient for automatic control. It can also be used to configure the speed alarm device according to the user's requirements.

LS-type screw machine has been widely used in various sectors of the national economy, such as building materials, metallurgy, chemical, power, coal, machinery, light industry, food and food industry, suitable for conveying powder, granular, small pieces of materials such as cement Such as coal powder, grain, fertilizer, ash, sand, coke, etc .. Not suitable for conveying perishable, viscous, easy to agglomerate the material, LS screw conveyor working environment temperature is usually -20 ~ 40 ℃, For the -20 ~ 80 ℃, LS screw conveyor suitable for horizontal and small angle layout, inclination to not more than 15 ° is appropriate, such as the tilt angle is too large Please use GX series screw conveyor, or contact with our technical department for a separate design The

Product structure and principle:

LS-type screw conveyor is a non-flexible transmission of the conveyor device, screw conveyor commonly known as the dragon, is the mineral, feed, grain and oil, the construction industry in a wider use of a transport device, it applies to particles, Shaped and small pieces of material horizontal transport, tilt transport, vertical transport and other forms, the transmission distance from 2 meters to 70 meters, a variety of specifications, and according to customer demand for production. Uses: can regularly control and continuous delivery of powder and small pieces of materials, such as food, feed, coal, cement, clinker, compound fertilizer, sand, cereals, coal, stones and so on. The structure is simple and novel, easy maintenance, advanced technical indicators, cross-sectional size is small, good sealing performance, safe and convenient operation, easy to install, unloading; intermediate crane bearings using rolling or sliding two structures, are set dust, Sealing device, easy operation and maintenance.

Screw conveyor works:

When the screw shaft rotates, due to the gravity of the material and the frictional force associated with the wall of the tank, the material can only move forward along the bottom of the conveyor while the blade is pushed, as if the nut can not rotate The rotating screw is the same as the translational movement. The movement of the material in the intermediate bearing is dependent on the thrust of the material coming forward. Therefore, the transport of materials in the conveyor, is entirely a slip movement. In order to make the screw shaft in a more favorable state of tension, the drive and discharge ports are generally placed at the same end of the conveyor and the feed port is placed as close as possible to the end of the other end. Rotating the spiral blade The material is conveyed so that the material does not rotate with the screw conveyor blade. The force of the material itself is the weight of the material and the frictional resistance of the screw conveyor housing to the material. The face of the leaves according to the different materials are solid surface, belt type, leaf type and other types. Screw conveyor screw shaft in the direction of movement of the material has a thrust bearing with the material to the screw of the axial reaction force, in the long length, should be added to the middle of hanging bearings.

Structural features:

1, screw shaft and hanging bearings, head, tail shaft connection are used to insert the tongue, installation, removal without axial movement, easy maintenance. Core length, hanging less, less trouble points.

2, the use of variable diameter structure, increase the bearing at the volume, to avoid hanging bearings and materials contact, hanging bearing life of up to two years.

3, the transmission parts are used floating connection, hanging bearings for the universal joint structure, so that the spiral body, hanging bearings and tail assembly to form a whole body of the floating body, in a certain range with the transmission resistance can be free to avoid rotation, Not blocking material.

4, head and tail bearing are in the shell, all bearings with multi-layer sealing and sealing technology, bearing long life. In the case of

LS type screw conveyor and GX type screw conveyor difference:

LS-type screw conveyor is the use of rotating spiral will be transported along the fixed material within the shell to carry the transfer work, the head and tail bearings moved to the shell, the use of sliding bearings with a sliding bearing dust seal, General use of powder metallurgy, conveying cement using blankets bearing pad, hanging shaft and screw shaft using slider connection.

LS-type screw conveyor performance characteristics:

1. Carrying capacity, safe and reliable.

2. Adaptability, easy installation and maintenance, long life.

3. Machine small size, high speed, to ensure fast and uniform delivery.

4. The discharge end with a cleaning device, the whole low noise, strong adaptability, access to the material position is flexible.

5. Seal is good, the shell is made of seamless steel pipe, the end of the flange with each other to connect into one, good rigidity. GX tube screw conveyor is the use of rotating spiral will be transported along the fixed material within the shell to complete the transfer of work. Head and tail bearings moved to the outside of the shell, the use of sliding bearings with sliding bearings with dust seal, the general use of powder metallurgy, cement transmission blankets with blankets, hanging shaft and screw shaft with a slider connection.

GX tube screw conveyor is not suitable for conveying perishable, viscous, easy to agglomerate material, these materials will be wrapped in the spiral on the transfer, and then spin without moving forward or in the hanging bearing at the formation of materials Of the plug, leaving the screw conveyor can not work properly. Spiral diameter from 200 mm to 500 mm, a total of five specifications, the length from 2 to 70 meters, the selection of the standard length of the standard, the special needs can be made in the optional section.

GX tube screw conveyor Features:

(1) small size, high speed, to ensure fast and uniform delivery.

(2) good rigidity, good seal. Shell made of seamless steel pipe, the end of the flange connected into one.

(3) the discharge end with a cleaning device, the whole low noise, strong adaptability, access to the mouth position flexible.

(4) carrying heavy weight, safe and reliable.

(5) adaptability, easy installation and maintenance, long life.

Product Application:

The screw machine has been widely used in various sectors of the national economy, such as building materials, metallurgy, chemical industry, electric power, coal, machinery, light industry, food and food industry. It is suitable for conveying powdery, granular and small materials such as cement and coal Powder, grain, fertilizer, ash, sand, coke and so on. The temperature of the working environment is usually -20 ~ 40 ℃, the temperature of the conveying material is generally -20 ~ 80 ℃, LS screw conveyor suitable level and small angle of inclination Arrangement, inclination to not more than 15 ° is appropriate, such as the tilt angle is too large Please use GX series screw conveyor.
