Multi shafts screw conveyors are used in the flour milling
industry, especially for conveying cereal grains,flour , and
by-prosucts such as bran. Multi shaft screw conveyors are
manufactured from carbon steel with food-grade surface finishing
.They are made up from a U-shaped trough that is equipped with at
least one outlet spout,an end plate at each trough end, helicoid
screw flighting welded on a centre pipe with a coupling bush at
each end ,two end bearing assemblies complete with shaft sealing
unit,a number of intermediate hanger bearings with self-lubricating
bushes depending on the overall length of the screw conveyor, and
bolted trough covers.
Conveying features:
Shaftless screw conveyors are mainly used in industries such as
chemical, food, medicine, paper making, beverages, and
environmental protection to deliver highly viscous materials,
paste-like viscous materials (such as chemical raw materials, waste
pulp, malt, sludge, etc.) and Easy-wound material with unique
advantages.
The advantages of the Multi shaftless screw conveyor:
1, with environmental characteristics. Because the conveyor is a
totally enclosed design, it is difficult for the material to
receive contamination during the transport process.
2. Compared to the shaft screw conveyor, the delivery volume is 1.5
times that of the shaft conveyor with the same diameter.
3. Blockages rarely occur during work.
4, the transmission distance up to 60 ~ 70m.
5, generous appearance, while saving space, easy to operate,
reasonable price.
Multi shaftless screw conveyor Using requirements:
a. The WLS non-shaft screw conveyor shall be started without load,
ie it shall start when there is no material in the casing. After
starting, it can feed to the WLS non-shaft screw conveyor.
b. When WLS non-shaft screw conveyor is initial feeding, the
feeding amount should be gradually increased until it reaches the
rated conveying capacity, and the feeding material should be
uniform, otherwise it will easily cause the accumulation of
conveying material, overload of the drive device, and make the
entire WLS shaftless Screw conveyor damaged.
c. In order to guarantee the requirements of WLS non-shaft screw
conveyor without load, WLS non-shaft screw conveyor should stop
feeding before stopping, so the material in WLS shaftless screw
conveyor casing can stop running after it is completely conveyed.
d. The hard material shall not be mixed into the conveyed material
to avoid screw jamming and damage to the WLS shaftless screw
conveyor.
e. Always check the working status of each part of the WLS
shaftless screw conveyor during use and pay attention to whether
the fasteners are loose. If the parts are found to be loose, the
screws should be tightened immediately to make them resolidified.
f. The cover of the WLS shaftless screw conveyor should not be
removed when the machine is running to avoid accidents.
