description LS
screw conveyor is the updated product of GX type
screw conveyor. It is designed according to standard of
JB/T679-95 screw conveyor.The machine features high
reliability, long lifetime,good applicability, convenience to
install and maintain. The temperature of materials can reach up to
100 °C, the biggest dip angle can be up to 45°.The
Screw Conveyor is a conveyor device, which
utilizes the rotation of the helical axis in the Ugroove to achieve
the delivery of materials.Working principleThe rotating helical
blades of LS type screw conveyor move the materials to the screw
conveyor for conveying. The force that makes the materials not
rotate with the blades of the screw conveyor is the weight of the
materials and the friction resistance of the shell of the screw
conveyor to the materials. For the spiral blades welded on the
rotating shaft of the screw conveyor, the surface types of the
blades include solid surface type, belt surface type, blade surface
type and so on according to the different conveying materials. The
screw shaft of the screw conveyor is provided with thrust bearing
at the end of the material movement direction to give the axial
reaction force of the screw with the material. When the captain is
long, the middle hanging bearing should be added.Highlight
advantages1. It adopts small diameter and variable pitch design
with high speed. It can transport 458 cubic meters of powdery,
granular and small pieces of materials per hour, and the conveying
length is up to 70 meters.2. The head and tail bearings are moved
to the outside of the shell, eliminating the possibility of
reducing the service life of the bearing due to loose sealing and
material leakage.3. The middle suspension bearing adopts two
interchangeable structures of rolling and sliding, both of which
are equipped with dust-proof sealing devices and labyrinth seals.
The seals are made of nylon and plastic king, with strong sealing
and good wear resistance. The sliding pad has cast copper pad that
needs lubricant, alloy wear-resistant cast iron pad and copper
based graphite low oil lubrication pad, and the service life of the
bearing can reach 10000 hours.4. The surface of spiral blade is
coated with wear-resistant material, and its service life can be
doubled compared with conventional blade.5. The transmission part
adopts cycloidal gear reducer, which has low noise, strong
adaptability and convenient operation and maintenance.Ls / GX screw
conveyor is generally composed of conveyor body, inlet and outlet
and driving device. The spiral body is composed of three parts:
head section, middle section and tail section. Driving device: q
series reducer + Y series motor, YTC gear motor.Feeding and
discharging devices: there are four kinds of feeding port, square
discharging port, manual pushing discharging port and rack
discharging port. The user shall weld the opening on the machine
body at the use site. When arranging the positions of the inlet and
outlet, pay attention to ensure the distance from the outlet to the
end, and avoid the collision between the outlet and the oil filling
cup of the hanging bearing, the connecting flange of the casing,
the base, etc.Screw machine body: a thrust bearing is installed in
the head section to bear the axial force, and a bearing is
installed in the middle section and tail section to support the
screw shaft. At the same time, there is an axially movable radial
bearing in the tail section of the screw conveyor to compensate the
error of the length of the screw shaft and adapt to the temperature
change.Industry applicationLs / GX screw conveyor is suitable for
conveying powdery, granular and small materials, such as cement,
grain, chemical fertilizer, sand, coke, pulverized coal, ash, etc.
Grain and food industry: flour, soybean, peanut, starch, milk
powder, salt, sugar, vitamin supplements, etc.Building materials:
cement, cement raw materials, paid materials, etc.Plastic industry:
plastic powder, plastic particles, ground pieces, etc.Wood:
sawdust, sawn wood surface, by-products, etc.Ceramics: clay, clay,
silica, sand, polishing materials, plaster of Paris, aluminum oxide
powder, etc.Agriculture: livestock feed, nourishment, powder,
etc. Ls screw conveyor is equivalent to iso1050-75
standard, and its design and manufacture comply with zbj81005 1 ~
2-88 professional standard of LS screw conveyor. LS screw conveyor
is improved from GX screw conveyor. The main improvement is the
hanging bearing structure, so that materials can pass more
smoothly. The working environment temperature of LS
screw conveyor is usually - 20 ~ 40 ºC, and the temperature
