2 Page 1 OVERVIEW Rocky Mountain Industrial Solutions as subcontractor for Rocky Mountain Industrial Services (similar name but 2 separate and unrelated companies) has successfully completed the hot oil flushing, oil filtering and reservoir cleaning of critical equipment in Acme s cement plant nearing completion in The Southwest. The scope of our work consisted of reservoir, oil line, and piping inspection and cleaning and cleaning of fill oil. Following inspection, installation of necessary by passes to allow systems flushing were installed. Systems were then flushed with a low viscosity non additive flushing oil at temperatures of 15 F and at adequate Reynolds numbers to produce turbulent flow throughout the system. After reservoirs and piping were thoroughly cleaned, system oil was then circulated through the vacuum dehydrator assuring that the appropriate cleanliness level and dryness for each lubricating, hydraulic and gear lubricant were met. The clean oil was then filled into the clean system reservoirs. In some cases, reservoirs had been prematurely filled with the lubricating, hydraulic or gear oil which necessitated the use of this system oil as the flushing medium. In other cases, the draining of the system and subsequent flush using hot flushing oil was necessary. Both of these scenarios added to the time required to achieve the desired level of cleanliness of the oils and systems. Samples of flushing oils and finish lubricating oils were checked by inline particle counter and collected for microscopic analysis to ascertain cleanliness levels. Samples of the installed lubricating, hydraulic or gear oil were sent to an independent laboratory for confirmation. This reports depicts the work performed in each mill and documents the results. This report also documents incidents of gross contamination as they were encountered.

These missing or loose connections were repaired by Rocky Mountain Industrial Solutions prior to flushing. The flush of the HRB system was originally set up to flush the entire system in one flushing. After necessary connections and bypasses were made flushing began but had to shut down almost immediately due to spike in system pressure. After several attempts, is became apparent that total system flush could not be accomplished due to blockages in system piping. Each of 3 sections were isolated and each section was flushed individually. The system piping of each section was found to be plugged with extraneous material which was dislodged by increasing pressure and flow during the flush. A representative sample of this material is d e p i c te d on page 29. The I S O c l e a n l i - ness level of the flush oil is shown on the graphs on the left.

This re sulted in 6 hours of worthless circulation through the vacuum dehydrator before this action was halted. As the above graph show s, the gearbox and subsequently the oil was full of contaminants. ISO 32 oil in a system such as this cannot generate sufficient turbulence to provide a good flush. After 6 hours, this oil was drained and disposed of and this reducer was properly flushed with hot low viscosity flushing oil. This system contained gross contamination that was eventually flushed out. The contamination is shown in the pictures on pages 38 & 39. If this system was not drained and flushed and lube oil replaced, catastrophic damage to the reducer may have occurred.

61 Page 6 RECOMMENDATIONS FILTER NEW OIL BEFORE ADDING Just because a drum is sealed doesn't mean the oil it contains is free of abrasives. There is a common misconception that new equals clean. There is no guarantee of this. The base oil, blending, packaging and logistic processes can all lead to contaminant ingress. Likewise, drums are never perfectly clean, particularly if they are reconditioned steel drums. New plastic containers are generally the cleanest followed by new steel drums. A good rule of thumb is that it cost 1 times as much to remove a gram of abrasive particle once it has entered your system than it does to exclude it in the first place. It can cost 1 to 1, times that figure, or more, to leave the gram of abrasive contaminants in the system, depending on mechanical design, machine criticality, contaminant abrasively, etc. Filtering new oil is among your cheapest options for improving the mechanical reliability of bearings, gearing, hydraulic, systems, engines, etc. OIL SAMPLING OF CRITICAL EQUIPMENT Knowing the condition of your lubricants is essential to keeping manufacturing plants running smoothly. This can be accomplished through a thorough oil analysis program that tracks multiple critical wear-related characteristics of oil in service by comparing the results with previous reports and noting the trends. Such a program helps identify contamination, lubricant degradation, abnormal machine wear and problems with sampling. It also can transform a lubrication program from timebased to condition-based, eliminating unnecessary changes. Total acid number This measures the amount of oxidation that the fluid has undergone since startup. It is a useful measure of the performance of a lubricant, and a good predictor for when it should be replaced. As lubricant fluid is used and exposed to the air, its oxidation level increases, decreasing the effectiveness of the lubricant. A total acid number that is significantly higher than its initial value is a key warning sign of lubrication problems.

62 Page 61 RECOMMENDATIONS Particle Count- Equally important is a system s particle count. This provides information about the cleanliness of the system and performance of the filtration system. Dirt and other impurities accumulate in the lubricant, decreasing its effectiveness. A properly functioning filtration system can extend the life of this measure, but if the particle count increases significantly from its initial values, this is an indication that the lubricant should be replaced. Water Water is a major enemy of lubricants. Especially in moist environments, where the lubricant is exposed to open water or steam, the water content of a lubricant can significantly impact performance. Different lubricants have varying tolerances for water content. For example, a polyalkylene glycol has higher water limits than a polyalphaolefin product. Each lubricant has its own guidelines on acceptable parts-per-million (ppm) water levels. These can be obtained from your lubricant supplier. Regardless of the lubricant you use, water content that exceeds acceptable levels is a serious warning sign of impending lubricant failure. Metals Metals analysis can reveal information about the wear in your system and the performance of certain additives. Metals are found in lubricants both as a result of additives in the fluid and as a result of wear, depending on the type of lubricant and the configuration of your system. The typical oil sample test targets common engine metals such as copper, aluminum, and iron in order to provide a measure of the amount of metal ingested by the lubricant. As with water content, different lubricants have varying tolerances for metal content. Again, plant managers should consult with their lubricant supplier to best predict when metal analysis results indicate the need for lubricant change. IF DRUMS ARE STORED OUTSIDE It is always better to store drums inside but if drums are stored outdoors for extended periods the should have drum covers. Prior to placing the drum cover on the drum, mark where the bung is on the side of drum. Ninety degrees to the bung, lay a wicking device (such as a strand from an industrial mop) over the chime so that half is on top edge of drum and half is hanging outside of the drum. Install drum cover as normal. If possible, set the back edge of the drum on a 1x2 board or equivalent to create a slope so that any condensation forming inside of the drum cover can be directed downward toward the wick and out to the ground. Note: Wick, if placed 9 degrees to the bung, will be 18 degrees from board or on downside of slope.

63 Page 62 RECOMMENDATIONS USE DESICCANT BREATHERS All gearboxes, reservoirs and storage tanks are designed to breathe and have a certain amount of head space to accommodate the air pressure differential between the equipment housing and surrounding atmosphere. This breathing over time will introduce particulate matter and water into the oil. Particulate and water contamination are the leading causes of lubricant related equipment failure. Proactive exclusion of these contaminants is crucial to reliable system performance. Incorporating ISOCLEAN Solutions Desiccant Breathers into your lubricant program is the solution. ISOCLEAN Desiccant Breathers are better than traditional breather caps since most breather caps are rated at 4 microns and small particles (3-2microns are often the most damaging. Traditional breather caps offer no protection against the ingression of water and water vapors. ISOCLEAN Desiccant Breathers as part of a reliability centered maintenance plan, can help extend equipment life exponentially. ISOCLEAN Desiccant Breathers use a unique, multi-tiered filtration process to prohibit the entry of water and particulate contamination (b = 2) into lubrication systems. ISOCLEAN Desiccant Breathers are filled with a hygroscopic agent (water adsorbing) that traps and adsorbs moisture contained in the air entering the filter. They are filler/breather caps, and a visual color indicator clearly shows when the unit needs to be changed-out. ISO CLEAN DESICCANT BREATHERS ARE AVAILABLE THROUGH ROCKY MOUNTAIN INDUSTRIAL SOLUTIONS APPLICATIONS INCLUDE Gearboxes Lubricant reservoirs Mobil and ground support equipment Paper machines Hydraulic systems Bulk storage tanks, totes, drums Transformers and turbines Other vented fluid systems

64 Page 63 RECOMMENDATIONS USE AUTOMATIC GREASE LUBRICATORS (EM) We strongly recommend the use of ElectroMechanical Grease Lubricators (EM). Automatic lubricators take much of the worry out of one facet of preventive maintenance. Often, the name of the game in manufacturing productivity is preventive maintenance; that is, carrying out economical maintenance now to prevent equipment breakdowns before they occur. Considering that nearly 9 percent of bearings are lubricated with grease, and 8 percent of bearing failures are lubrication related, a crucial aspect of preventive maintenance is ensuring that bearings are maintained at proper lubrication levels, with adequate grease to help keep out water, dust and other contaminants. Automatic lubrication devices guarantee a lubrication schedule and introduce only fresh lubricant. From a maintenance-engineering standpoint, the benefits of a single-point automatic lubricator include: Guaranteed continuous and controlled lubrication flow. No temperature increase during lubrication. Continued lubrication in dangerous areas while machines operate. No foreign particles in lubrication lines. Lubricated bearings in hard-to-reach, forgotten areas. Longer maintenance intervals. Reduced grease consumption through more efficient lubricant use. Longer operating runs and decreased downtime. Quick return on investment from reduced repair and maintenance cost. An electromechanical lubricator is a reusable, battery-powered, motorized unit with a replaceable lubrication canister. It features adjustable discharge periods and can be turned on and off with a switch. When activated, the motor powers a gear set that turns a threaded spindle to drive a piston that pressurizes the grease to 75 psi. Electromechanical unit performance is temperature-independent and discharge periods are more precise than with the electrochemical units. Automatic and precise grease delivery produces many benefits, the most important of which are extended bearing life and reduced downtime. An electromechanical lubricator can be mounted in any convenient location as far as 12 feet from the bearing.
