SS316L Material U Model Screw Conveyors Sprial Auger Conveyor
I. Overview.
Screw conveyors are widely used in chemical industry. Screw
conveyors are mainly used to convey powder, granular and small
materials, such as coal powder, soda ash, reclaimed rubber powder,
zinc oxide, calcium carbonate and small coal, etc., screw conveyor
The machine is not suitable for conveying materials that are
perishable, viscous, and easily agglomerated.
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
Screw conveyors are suitable for various industries, such as
building materials, chemical industry, electric power, metallurgy,
coal, food and other industries, and are suitable for horizontal or
inclined conveying powder, granular and small lump materials, such
as coal, ash, slag, cement, grain, etc. , The material temperature
is less than 200℃. The screw machine is not suitable for conveying
materials that are perishable, viscous, and easily agglomerated.
III.Characteristics are below
Simple structure, small cross-sectional size, good sealing,
reliable work, low production cost, convenient for intermediate
loading and unloading, and the conveying direction can be reversed
or in the same direction and opposite two directions. In the
process, the materials can be stirred, mixed, heated and cooled.
The material flow can be adjusted through the loading and unloading
gate. However, it is not suitable to transport materials that are
perishable, viscous, agglomerated and bulky. During the conveying
process, the material is easy to be broken, and the screw and the
trough are easy to wear.

VI.Equipment installation requirements
a. The on-site installation of the inlet and outlet should make the
flange support surface of the inlet and outlet parallel to the axis
of the screw machine; the flanges connected to it should be tightly
fitted and there should be no gaps.
b. After the screw machine is installed, check whether there is
enough lubricating oil in each oil storage place, if not enough,
add enough, and then carry out a no-load test run; check the screw
machine after running for more than 4 consecutive hours. Accuracy
of assembly: Stop immediately when an abnormality is found, and
operate after treatment until it is in a good operating state.
c. The operation of the screw machine should be stable and
reliable, and the fasteners should not be loosened. The reducer has
no oil leakage, no abnormal sound, electrical equipment is safe and
reliable, and the no-load operating power is less than 30% of the
rated power.
