Monitoring the Differential Pressure of Your Baghouse
Tips from Schenck Process Service Technicians to ensure your equipment continues to run accurately and efficiently.
- The differential pressure reading is a simple way to get a quick assessment of how your baghouse is running. It is important to monitor the pressure differential of your baghouse on a regular basis (at least once a day), and make sure the pressure differential gauge is working correctly.
- If there are any sudden changes in the pressure differential, whether up or down, first make sure the two lines connecting the gauge are not plugged, crimped or damaged.
- If the gauge is reading “normal” range, and there are no emissions visible, the filter is running properly. If, however, you begin to notice an upward creep in the pressure differential, it can be an indication that the filter bags are beginning to plug and may need to be replaced.
- If there is sudden upward spike in pressure differential, it is usually symptomatic of an upset condition in the baghouse (for example, a sudden influx of moisture-laden air that decreases bag permeability) or possible problems with the bag-cleaning system.
- If there is a sudden decrease in pressure differential, often accompanied by visible emissions, may indicate actual failure of one or more filter bags.
- If you have any questions please contact our Baghouse Service group at 800-821-2476.

If a belt does not perform according to the manufacturer’s claims by wearing prematurely, ripping too easily, disintegrating due to excessive heat or because of oil penetration, the risk to life and limb is relatively small. But if a conveyor belt that is specified as being fire resistant catches fire but does not resist the fire the way that it should do then it will literally ‘convey’ the fire throughout the site. The consequences can be catastrophic.
Is cost being put before safety?
Due to the financial pressures, more and more organisations are being forced to examine their day-to-day running costs and, almost inevitably, seek cost savings. The pressure to cut costs seems to be influencing buying decisions concerning fire resistant conveyor belts but is price being put before safety? The discovery that a belt is not sufficiently fire retardant is only likely to be made when it is too late.
Anecdotal as well as factual evidence gained from extensive laboratory testing certainly indicates that even some of the biggest users of conveyor belts are using belts that are not as resistant to fire as they are claimed to be. In a growing number of instances, many bulk material handling sites that should be using fire resistant belting are operating with non-fire resistant belts simply in the pursuit of ‘economy’.
At the same time, insurance companies are becoming increasingly concerned. According to at least one major insurer, claims for fires directly involving conveyor belts are costing an average of nearly $8 million per claim. To find out more about this highly important and complex subject we sought the guidance of the chairman of the international standards (ISO and CEN) committee and one of the world’s leading authorities in conveyor belting, Sytze Brouwers.
No conveyor belt is fire proof
Fire resistant standards for test methods and specifications applied to conveyor belts are becoming increasingly stringent and can be very confusing. The first and most important thing to bear in mind is that conveyor belts cannot be totally fire proof. Using special additives and chemicals, the rubber used in the top and bottom covers that protect the carcass of the belt and the rubber skim between the fabric plies of the carcass can be engineered to resist fire but the complete structure of the belt cannot be made fire proof. The fabrics used in the carcass of the belt most commonly contain polyester and nylon, which have virtually no resistance to fire. In other words, every belt will begin to burn (and continue to burn) when exposed to a naked flame that has sufficient energy to ignite the belt.
What is meant by ‘fire resistance’?
Once a belt is ignited by flame then it will continue to burn until it is no longer exposed to the source of ignition. Although commonly referred to as ‘fire resistance’ within the conveyor belt industry, in real terms it is the ability of specifically designed rubber to self-extinguish once the source of ignition is no longer present.
Environments with inflammable dust and gas
EN 12882 is the standard for safety requirements for conveyor belts for general-purpose use (not underground). The most basic electrical and flammability safety requirement is EN 12882 Category 1. For environments where dust or other potentially combustible materials are involved, it is essential that the conveyor belt cannot create static electricity that could ignite the atmosphere. Belts need to be able to allow static electricity to pass through the metal frame of the conveyor structure down to earth rather than allow static to build up. At Dunlop we decided some time ago that the safest approach was for all of our belts to be anti-static and conform to EN/ISO 284 international standards. This means that they can all be used in ATEX 95 (94/9/EC Directive) classified zones. Some people mistakenly believe that all belts used in ATEX classified zones must be flame retardant but actually this is not the case.
ATEX regulations apply to industrial environments where there is a risk of explosion because dust or gas is present in the atmosphere. For those organizations that are buying conveyor belts for use in ATEX regulated areas it is very important to ask potential suppliers for a copy of a certificate provided by an appropriate independent testing authority such as the German Institute Dekra Exam GmBH.
Above-ground and general service applications
Because fire safety is such an important issue there are numerous safety classifications and international standards for which there are many different tests used to measure the self-extinguishing properties of conveyor belts. Rubber belts reinforced by layers of textile fabrics (multi-ply) or steelcord reinforcement are the most commonly used type above ground and in general service applications. The basis of most tests for belting used in normal industrial applications is EN/ISO 340. This standard makes the distinction between fire resistance with covers (K) and fire resistance with and without covers (S).
The relevance of “with and without covers” is that as belt covers wear during their operational life the amount of fire resistant rubber protecting the flammable carcass reduces. The best way to decide between ‘K’ and ‘S‘ grades is to consider the material being carried. For moderately abrasive materials then ‘K’ grade is usually perfectly adequate. This also applies to elevator belts. However, if the material is abrasive and tends to wear the top cover quite rapidly then the safest option is be to choose the ‘S‘ grade.
In both ‘K’ (EN 12882 Class 2A) and ‘S’ (EN 12882 Class 2B) grades, the rubber skim that bonds the fabric layers of the carcass together should also be fire resistant. In the case of ‘S’ grade (fire resistant without covers), the rubber skim should be thicker than the skim used for ‘K’ grade. The easiest way to tell if a ‘K’ grade belt has the required thicker rubber skims is to obtain technical datasheets from the manufacturer for both ‘S’ grade and ‘K’ grades and compare the carcass thickness figures.
Another reason why buyers should always request technical datasheets before placing an order is that they include information on the level of abrasion (wear) resistance. The ingredients used to create a fire resistant rubber compound generally have an adverse effect on its wear resistant properties. Consequently, fire resistant belts tend to wear faster and as the thickness of the rubber reduces so does the level of protection given to the inflammable carcass. To avoid premature belt replacement, in the case of purely fire resistance belting, buyers should always demand an average abrasion resistance level of no more than 150mm³.
At Dunlop our rubber compound technicians have proved that it is possible to have the best of both worlds by developing a fire resistant rubber that also has good resistance to abrasion. In fact our technicians have created a compound that has 50% better wear resistance than the DIN Y standard for abrasion resistant rubber. This means that the belt retains its resistance to fire for much longer and at the same time extends the operational lifetime by the same proportion. However, laboratory tests have revealed that this is very much an exception to the rule within the conveyor belt industry.
EN/ISO 340 tests involve exposing 6 individual samples of belt to a naked flame causing them to burn. The source of the flame is then removed and the combustion time (duration of flame) of the test piece is recorded. A current of air is then applied to the test piece for a specified time after the removal of the flame. The flame should not re-ignite.
The time it takes for the belt sample to self-extinguish is then measured. The duration of continued burning (visible flame) should be less than 15 seconds for each sample with a maximum cumulative duration of 45 seconds for each group of six tests. This factor is of paramount importance because it determines how fire can be effectively carried along a moving belt. The effects of fire being literally ‘conveyed’ to adjoining buildings can be seen in some of the photographs.
Even if a manufacturer states that their fire resistant belt has passed the ISO 340 test, the buyer should still exercise caution. A typical conveyor belt can easily travel more than 40 meters within the 15 seconds sufficient for a belt sample to pass the test but which would still allow the belt to carry flames over a potentially dangerous distance. For this reason our required time limit standard in Dunlop is no more than one second, ideally 0 seconds. Buyers of fire resistant belt are therefore recommended to ask to see copies of the test results and to check that the laboratory that has carried out the tests has EN ISO 17025 certification.
What standard of fire resistance do I need?
When choosing a fire resistant conveyor belt, establishing the correct level or standard of fire resistance needed for a specific application or environment is of crucial importance. This can present one of the most difficult challenges for users of conveyor belts. For the vast majority of belts being used in the open air, Class 2A or 2B would be perfectly adequate. Class 2A demands that the belt is able to pass the ISO 340 test described earlier with the covers intact on the belt samples (K grade). Class 2B requires that the belt that can also pass the ISO 340 test with the top and bottom cover rubber removed (S grade). As mentioned earlier, the electrical conductivity of the belt also needs to fulfill the requirements of ISO 284.
If you are still unsure of the fire resistant grade of belting needed then it is best to carry out an internal risk assessment. If the expertise for this does not exist within your company then there are a number of external organizations (and almost certainly your insurers) that can perform this function for you.
For conveyors carrying materials that contain oil such as wood chips and biomass (some types can spontaneously combust), rubber compounds that are resistant to fire, abrasion and oil are available. There are, of course, two types of oil resistance – mineral and vegetable. This is yet another important consideration when deciding on the correct type of fire resistant belt so buyers are recommended to be very specific when making requests for quotations from manufacturers and suppliers.
CEN fire test standards
One of the most problematic aspects of fire testing rubber conveyor beltsfor industrial use above ground is that most of the test methods were established many years ago specifically for underground mining belts. Enormously complex and very costly testing has to be made by independent testing institutions. Because of environmental regulations, large-scale gallery fire tests now involve using a 12-meter long container filled with carbon to filter the smoke emissions before being released into the atmosphere. In order to be awarded a safety standard certificate every belt type has to be independently tested. For some tests a minimum of 20 meters of belt is needed
Such tests can easily cost up to 20,000 euros or more. For the manufacturers of solid woven underground mining belts and steelcord belting this is not a particularly big problem because there are a relatively small number of different belt types that have to be supplied for testing in large quantities. Although the test certificates are valid for several years, these large-scale tests present a huge and costly problem to manufacturers of rubber belting for above ground use because there is a much wider range of belt types. Such complex test methods have made it extremely difficult to develop improved levels of fire safety because if a belt sample fails the tests then the technicians have to go back to the drawing board to make further changes to the rubber compound and then embark on another round of expensive tests.
Apart from hindering development of fire resistant belting, it also means that it is very difficult to adequately test those belts that manufacturers claim reach specific levels of fire resistance. This is one of the reasons why there are so many end-users operating conveyors fitted with belts that provide totally inadequate levels of fire safety.
New CEN fire test standards to be introduced
The problem has long been recognised by the CEN standards committee and over recent years they have been trying to find a solution. Following recent meetings attended by technical experts from all over Europe, the Committee European de Normalization will be introducing several positive changes in 2014.
Agreement has been reached on using and adapting tests already in existence for quality standards such as DIN and BS that will involve much smaller scale tests using much smaller equipment. This will mean that major manufacturers will be able to experiment and carry out testing in their own laboratories. Ironically, these new test methods will actually be even more demanding than the old, large-scale tests. Major insurance companies are already showing interest and are becoming involved in discussions. For them, and for all genuinely safety conscious organisations, this can only be very good news.
Don’t play with fire
Although manufacturers and suppliers may be able to provide test certificates, in some cases the certificate may only relate to the belting that the manufacturer produced for test certification purposes. In reality, the actual belt delivered to site may well not be up to the required standard. For greater peace of mind we would suggest ordering an extra meter of belt and then have that piece of belt tested by an accredited testing authority or laboratory.
The price of not exercising caution simply cannot be calculated.

I have an issue with a materials handling system and now where do I go with it?
This experience and question is being considered all the time as any given materials handling plant is going through this frequently. It can be so painful because the plant management wants it fixed quickly and with as little as possible economic impact. You and / or your internal resources are completely overwhelmed with the task of diagnosing the problem by yourself and you know that you need help. You suspect that the original equipment manufacturer maybe offering the most expensive fix with the longest time frame attached to it. Now what do you do?
At the root of the problem is surprisingly one key item: You. What I mean by that is that you let the situation get to you. This is meant in terms of economic and time frame pressure exerted on you by either management and or the urgency of the project. Now you make less strategic decisions due to not taking your time thinking through the problem at hand. What happens is that you attempt fixing the issue yourself even though you do not know what you do not know. In the end the problem can be made worse and now this can come back and reflect badly on your career.
Planning is everything here. You do not plan, you plan to fail. The following is a cheat sheet summary of what you can do to plan through your issue:
- Define the problem. Seems a banality, but this is the top number one reason why no one will be ever be able to help you effectively. What I mean is for you to define a problem statement and then what you believe the root cause is.
- The root cause emerges when you ask yourself and the plant personnel involved in the challenge fives times “why”. For instance: Why do we experience a low conveying flow rate? By the fifth why you will have really narrowed it down to the root cause.
- Develop a problem narrative in writing and sketch it out. Sketches preferably should be to scale. Photos do wonders!
- Stay to describing what the equipment status and condition is, rather than what should have been (some folks are afraid to admit that there are issues in the plant, this is no time to be timid!).
- This may surprise you, but I would speak with the original manufacturer first about your issue. This may render totally positive responses and the fastest results to dealing with your issues. At least you get to know the way how professionals would solve the issue and how. You can still resort to the other methods of self-help, if the manufacturer blows you off or otherwise does not treat you like he should.
- Look at online resources like the Bulk Forum for help. Here it will be helpful categorizing your issue correctly and with the detail knowledge from point 1 inserted in your request for help.
- Look around and ask friends and your connections in the industry. If you are not connected, now would be a good time to get connected. One excellent resource is LinkedIn. It has excellent focus groups that deal with so many situations and if there is not one, start one.
- Finally, you can give the good old college try a chance. Doing this yourself can be as scary as it can be rewarding when you solve the issue. Point 1 really will come to your rescue as it helps eliminate as many as possible variables. Make sure to not making changes too quickly and too many at a time such that you can study cause and effect of what you are doing.
Now that you have a pre-flight check list I will leave you to making a few important choices. The first one is for you to choose actively whether or not you want to make a change. Scan for the support of your management and their back up as well as their financial commitment. Nothing is worse than having developed a detailed plan just to be told that neither money nor time will be made available to you. Then choose to plan your remedy and the resources to do this with. What problems will you start doing differently from now one? Choose wisely.
