Airslides are much like launders. The air fluidises the product and makes it flow like water. It is best to ask an airslide manufacturer for tray width and product depth. To establish air requirements you need to know the cloth characteristics and the product behaviour. Some Lab tests may be required.

It would be too risky to ask some sheetmetal fabricator to build you an airslide from scratch. Some experience is essential.

The blower is usually an industrial flat blade centrifugal fan delivering through galvanised pipe to manually adjusted nozzles along the side of the air tray. You need to work out the lengths of pipe run before you can establish a pressure loss. ■

I agree with John !st; FLSnidth are the people to start with. 20 years ago Johannes Muller (Hamburg) used to offer silo blending by bubbling air around through the bottom of the bin to homgenise material. It seemed like a good idea at the time. ■

kibbk - you seem to be keeping secrets from us. Your enquiry gives no details but you want to be given more details. At this rate is is either a blind guess, or you want people to contact you direct.

Some answers you get from a sales-person, others from a volunteer on this panel, others you have to pay for. Can we quote you a design fee? ■

As John 1st implies; you cannot expect the full textbook for free just because you think you know the title. Buy a book & then you can talk about common knowledge! ■

More and more I seem to see people wanting free design. If you can't do it yourself pay some to do it for you, there are plenty out there. ■

I appreciate Designer's view ,but some people would like to pay at modification level not at design level,this is very common.

Some of the information is mentioned below--

1. The open air slide slope varies from 6-10 deg.

2. The pressure to convey the cement in open airslides is 10 times compare the closed airslide sysytem.

3.The width varies acoording to the layout of air slides and also on other factors.

4. Size of blower and motor depends upon the size of air slide you have selected.

5. Be carefull about opening of various valves at the time of blending.
