Limestone Bucket Elevators and Screw Conveyor dispatched to Philippines

Last week,bucket elevators and screw conveyors used for conveying limestone were dispatched to Philippines,which would arrive with our clients within 12 days.
In order to meet our client’s requirement,and know well of their purpose,PK engineer suggested two bucket elevators and one screw conveyor,the information is as follows:

1.Bucket elevator 
Model:TDG250
Capacity:70t/h 
Lifting height:15m
Quantity:1 unit
2.Bucket elevator
Model: TDG315
Capacity:100t/h 
Lifting height:26
Quantity:2 unit
3.Screw conveyor
Model: LSY315
Conveying length:26
Quantity:1 unit
Purpose:conveying the limestone which are discharged from the silo outlet.
PK Machinery will follow up the further feedback after installation,we do hope we can cooperate once again in the near future!

Why does Screw Conveyor Occur Material Backflow

As we all know, screw conveyor has widely application in various industries, such as building materials, chemicals, power, metallurgy, coal carbon, food and other industries, and could be suitable for horizontal or inclined conveying. During operation of screw conveyor, once there are materials blocked in hanging bearing, which is called material backflow. If screw conveyor always occurs the phenomenon of backflow, then it will cause screw conveyor throughput greatly decrease. With regard to large capacity screw conveyor, the material backed flow is likely to undermine reducer, and result in reducer overburn as well as economic losses.

If it is seen from transportation process of screw conveyor, the speed of controller and slipping material determines the speed of material which is conveyed from screw conveyor. What’s more, conveyor filling coefficient determines the discharge time, and the speed is large or small depends on the size of screw arbor and motor. Therefore raise these two components size can successfully address the material backflow problem.
