Big Capacity Multi Shafts Screw Feeder Conveyor for Boiler Dust
Description:
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.
