DEAR Federico Escudero Fuentes,
Regarding dust collector,it should be well designed and the bags should be of proper size and fabirick,we have supplied bag filters for bitumen plant dust which is suppose to be the worst material to handle, we are also exporting our dust filters out side india.Please let us have your inputs ,we will design and supply a proper dust collector.Our people has got exposure working for companies like LURGI, GERMANY.
Regarding loading spout for clinker,there are lot of referances in india,a compact dust collector cartige type will definately work,dust collected in these types of dust collectors will be loaded out with the material in the truck.

Clinker Dust
Pleated filter cartridges do not work well when the dust load is heavy, such as in a product receiver-filter. The closed end of the pleats tend to pack with dust which can not be effectively removed by the pulse clean cycle.
A robust filter bag with a high release teflon surface might well be a good choice. As to the abrasion that you mentioned, the dust stream should be introduced into the filter in such a way as to minimize turbulence. Also, the filter can velocity (gas flow / area of the filter less the bag area) should be low, even in the range of 2 to 3 ft/sec.
Base your decision on test data. Reputable filter element manufacturers will have facilities to test your material, often at no cost, and will offer performance guarantees on the installed equipment.

For complete information you may like to read my article "Design Guide for Dust Collectors" published in the February 2005 issue of Chemical Engineering.
Cartridge type filter elements come in a large variety. Pleated type have different shapes and designs to suit the characteristics of the dust. One major benefit of these types of filter elements is that for the same length and diameter they provide a much larger surface area.

Pleated Cartridges -V- Bags
Dennis is right. A well designed fabric dust collector, with consevative filtering velocity, is the correct solution where the dust load is heavy.
Cartridges are often used inappropriately. They also have a limited life and are expensive to replace.

Re: Clinker Dust. Pleated Cartridges Vs Bags
Do not bother with pleated type bags.
The bags are expensive, fail in fatigue at the pleat, not common (so hard to get replacements) and do not work that well > dust is trapped in the pleat (U need high pulse air to clean them).
Sales people will tell U that they are great.
We had them in 2 units on clinker with dismal performance and we are back to normal bags.
U need to look at the whole system.
Avoid dust pickup with proper hood location and design.
Have a drop out hopper/section in the duct collector.
Air-to-cloth should be less than 1.5m3/m2/min.
Look at longer bags > extend the casing with an insert.
For truck loading > consider Cleveland Cascades or simple tele chute (which can jam with hardend dust) with sep. dust collector.
We do not have combined chutes/dust collectors for truck load....U also need to consider maint. access to the unit eg lift cage on forklift or such.
Cheers

Thanks for your answer.
We are going to try with one of them that a company send us as sample. I will tell you how did they work in a couple of months.

Clinker dust. pleated cartridges vs bags
Hello everybody
My name is Federico, and I work in a cement plant in Uruguay.
We are thinking in changing actual baghouses into spun bounded polyester pleated cartridges filters. We don't know how this cartridges are going to work with clinker dust. We really have abrassion problems here . I would like to know if anybody has heard of how do those cartridges works in clinker aplications.
We also are planing to buy a new telescopic dustless loading spout to load clinker from a silo into an open truck.
We have seen in market people who sell the spouts with a compact dust collector on the top of the spout. This is a compact dust collector, and also uses pleated polyester cartrideges. With this technology, no more baghouse and ductwork are required.
Does anybody seen this kind of spouts working with cement clinker? How does they work?
I'm really interested in your opinion.
I shall highly appreciate an early reply.
Regards
Federico Escudero Fuentes
