Screw Profile






LS-type screw conveyor in accordance JB/T679-95 "Screw" design and manufacturing standards, is GX type screw conveyor replacement. Head and tail bearing shift
To the outside of the housing, hanging bearings sliding bearings with dust seals, bearings generally use powder metallurgy, transportation of cement used blankets bush, hanging

with the sliding shaft and screw shaft
Block connection, disassembly screws,


Without moving the drive unit, demolition crane bearings without moving spiral, you can not remove the cover hanging bearing lubrication,
Machine reliability, long life, adaptability, easy installation and maintenance.
Screw conveyor has a simple structure, and making low-cost, sealing strong, safe and convenient operation, etc., in
Rooms can be multi-point loading, unloading. Widely used in chemical industry, building materials, metallurgy, food and other departments in the angle β <20 ° in the case, is

not conveying viscosity, non-perishable, non-
Locust caking powdery, granular and small pieces of material.mine conveyors
Screw machine is widely used in various industries, such as building materials, chemical industry, electric power, metallurgy, coal charcoal, food and other industries, for

horizontal or inclined conveying powder, granular and small
Bulk materials, such as coal, ash, slag, cement, grain, etc., the material temperature less than 200 ℃. Screw machine suitable for transporting perishable, viscous, easy caking

materials.
In concrete mixing station, screw conveyor role has been the greatest manifestation.
Closed by driving means formed by the spiral groove tank and turn the spiral passage of the groove inside the coal output.
Screw conveyor is characterized by: simple structure, small cross-sectional size, good sealing, reliable, low cost, easy to intermediate loading and unloading, conveying

direction
Reversible, can also conveyed in the direction opposite to two. But also on the material during transport stirring, mixing, heating and cooling operations. Loading and unloading

of materials can be adjusted through the gateAirport conveyor
Material flow. But not transport perishable, viscous, easy caking and bulk materials. Easily broken during transportation of materials, screw and trough easy to wear. Unit power

than
Large. Use and to maintain the tightness of the spiral chute with proper clearance between the trough.
Vertical screw conveyor is suitable for short distance vertical transportation. Flexible screw conveyor screw by a flexible shaft and blade composed of synthetic rubber, easy to

bend, according to the site
Or process requirements of any arrangement for space transportation. There are pull-type screw conveyor blade and pull the entire loss, now pull can be made arbitrary thickness

and size, the entire system should not pull
For nonstandard spiral.

Screw conveyor is metallurgy, building materials, chemical industry, food processing and other sectors and machinery widely used as a continuous conveyor.
Transportation of materials from the perspective of the direction of displacement divided into horizontal screw conveyor screw conveyor screw conveyor and vertical two types,

mainly used for a variety of powder
Like, granular and small block, such as the level of loose material transport and vertical lift, the screw conveyor suitable transport perishable, viscous, easy caking or high

temperature, afraid of pressure, there is
Larger corrosive special materials.
Screw conveyors are generally body material inlet and outlet and the drive unit has three major components; screw conveyor helical blades have a physical spiral surface with

spiral noodles and
Blade helicoid three forms, which vane helical surface application is relatively small, mainly used for transporting material viscosity and compressibility, this snail hanging

face, lost in complete
Send job, both of materials and finish stirring, mixing and other functions.
Screw conveyor and other transportation equipment, compared with a whole section of small size, good sealing performance, stable and reliable, can be more than the middle point

of loading and unloading and operational safety
Full, easy maintenance and so on.
