LS Model 12 Cubicmeter Per Hour U Trough Inclined Screw Conveyor
I. Overview.
The LS screw conveyor is designed and manufactured in accordance
with the JB/T 7679-95 "Screw Conveyor" standard. It is a
replacement product of the GX screw conveyor. Screw conveyor,
commonly known as auger, is a widely used conveying equipment in
the mining, feed, grain and oil, and construction industries. It is
made of steel and used to convey powder or solid particles and
other chemical and building materials products.
II. Working principle and Applictaion
The screw conveyor uses the rotating screw to move the conveyed
material along the fixed casing to carry out the conveying work.
The head and tail bearings are moved to the outside of the casing.
The hanging bearing adopts a sliding bearing and is equipped with a
dust-proof sealing device. The bearing bush is generally used
Powder metallurgy, the conveying cement adopts felt bearing bushes,
and the suspension shaft and the screw shaft are connected by
sliding blocks
LS type screw conveyor is widely used in various industries, such
as building materials, chemical industry, electric power,
metallurgy, coal, food and other industries. It is suitable for
horizontal or inclined conveying powder, granular and small block
materials, such as coal, ash, slag, cement , Food, etc., the
temperature of the material is less than 200℃. The LS screw
conveyor is not suitable for conveying materials that are
perishable, viscous, and easily agglomerated.
III.Characteristics are below
1. Large carrying capacity, safety and reliability.
2. Strong adaptability, convenient installation and maintenance,
and long life.
3. The whole machine is small in size and high in speed, ensuring
fast and uniform delivery.
4. The discharge end is equipped with a cleaning device, the whole
machine has low noise, strong adaptability, and flexible layout of
the inlet and outlet positions.
5. Good airtightness, the shell is made of seamless steel pipes,
and the ends are connected by flanges to form a whole, with good
rigidity.

VI. Equipment use requirements:
a. The screw machine should be started without load, that is, when
there is no material in the casing, the screw machine can be fed to
the screw machine after starting.
b. During the initial feeding of the screw machine, the feeding
speed should be gradually increased until the rated conveying
capacity is reached, and the feeding should be uniform, otherwise
it is easy to cause the congestion of the conveyed materials, the
overload of the driving device, and the early damage of the whole
machine.
C. In order to ensure the no-load starting requirements of the
screw conveyor, the conveyor should stop feeding before stopping,
and stop running after the material in the casing is completely
discharged.
d. Do not mix hard and bulky materials into the conveyed materials
to avoid screw jams and damage to the screw machine.
e. In use, always check the working status of each part of the
screw machine and pay attention to whether the fasteners are loose.
If you find that the machine is loose, you should immediately
tighten the screws to make it firm again.
f. The cover of the screw machine should not be removed when the
machine is running to avoid accidents.
