Airslide to Top Silo for Cement Handling

Posted in: , on 29. Mar. 2007 - 12:21

Material Handled : Cement

Density : 1400kg /cum

Handling capacity : 300tph

From Level + 15mtrs to Top Silo level +48mtrs

Old system used vacuum type handling which is not economic and high maintenance

Proposal :

1) Bucket Elevator with lift 30mtr to bring cement up to +45mtrs

2) Level + 45 will discharge from Bucket Elevator to Airslides with 8 degree decline which travel in 2 stages (due to not inline) with total length approx. 180mtrs.

3) Airslide will then discharge at level approx. +15mtrs to Bucket Elevator near to silo with lift 30mtrs.

4) Bucket Elevator will discharge at top silo approx +48mtrs height with optional of Airslide to extend discharge to silo centre

Questions : -

1) Can we curve on Airslide as to reduce from 2 stages to 1 stage for 180mtrs travelling

2) Whether Pipe Conveyor is better option of handling? Or any Available options in market which reliable and convincing.

Thank you

H. K. Low

Dear HK

Please fing below answers of your querries--

Questions : -

1) Can we curve on Airslide as to reduce from 2 stages to 1 stage for 180mtrs travelling

Curve on airlslide not possible,you can always change the route of airslide by installing a divertor valve/gate at the bottom of airslide .It will be easy for us if you will provide the G.A of existing system.

2) Whether Pipe Conveyor is better option of handling? Or any Available options in market which reliable and convincing.

If you will compare pipe conveyor with air slide then airslide is best option because of followig reasons-

1.Less power consumption at least 40-50%.

2.Less maintenance.

Please send your drawings of the existing system,we shall propose you the best option with supply of equipment.

Dear Mr Low,

Your proposed system consists of 2 bucket elevators for 30 m elevation each and 180 m of airslide plus the additional equipment s.a. fans, dedusting etc.

In this system the cement travels approx. 240 m of distance with 2 times 30m lifting.

Although you are not in favor of a pneumatic system, it is recommendable to consider a pneumatic pressure system from the first elevator intake to the destination silo.

The travel distance reduces to 210 m.

On the destination silo you will only need an extraction filter (which is needed anyway) and a maintenance free pipeline.

The pneumatic conveying installation is concentrated at the beginning and is easy accessible for maintenance.

Maintenance will be not excessive, providing a well engineered installation.

The 300 tons/hr over 210 m is a fairly common installation and the operation cost should be really investigated.

The design should be such that the optimum is achieved.

Future expansion to other silos is very easy achieved by adding a diverter with the additional piping to the new silo.

After you have executed this feasibility study, you can compare with other options.

success

i do not know much knowledge about the design of air slide system.

but i am glad to know from you all.

i am a sales from airslidel.net

we are professtional manufacturer of air slide fabrics.

one of my question is:

what is the main usage for air slide fabrics?

thanks for your help in advanced.
