tire and trunnion grinding: critical rotary drum maintenance

One of the easiest and most effective preventative maintenance procedures is tire and trunnion grinding – the practice of resurfacing the tire (riding ring) and trunnion wheel components to like-new condition. Since damage to these components has a compounding effect on the rest of the drum, keeping tires and trunnion wheels in good condition is the starting point for avoiding more severe issues

As the drum’s foundational support, problems that start in the tires and trunnion wheels work their way to other parts of the drum if not promptly addressed. When left untreated, the resulting stress on other components continues to build, exacerbating existing issues and promoting more severe damage

Rotary drum alignment is a primary contributor to overall drum performance and longevity. Much like tires and trunnion wheels, the alignment of a drum affects several components, and when allowed to run out of alignment, can result in a wide range of problems

tire and trunnion grinding: critical rotary drum maintenance

While there are many potential consequences of misalignment, one especially challenging result is the lack of control over axial thrust. The inability to properly manage axial thrust promotes excessive wear on one of the thrust rollers, which has the potential to cause thrust roller bearing failure. In turn, bearing failure can lead to the drum dismantling the thrust roller shaft. If dismantling of the thrust roller shaft occurs, the drum is able to roll off the trunnion rollers, causing catastrophic failure and severe damage to breechings, seals, trunnion base weldment, concrete piers, gears (or chain and sprocket), tires, and the drum shell

Drum vibration amplitude should be kept at a minimum in order to keep the drum running as smoothly and efficiently as possible, minimizing stress on all components. Excessive vibrations not only cause undesirable chattering, but they also quickly propagate to the rest of the drum, causing:

Dickinson Mechanical provides specialist services for Rotary Kilns / Vessels. The services are tailored for the main Rotary Equipment as well as the associated peripherals; including but not limited to key components like the support rollers and drive transfer units. Our precision onsite and offsite services coupled with our flexibility towards customers’ unique needs allow for significant reductions in equipment downtime

The majority of problems associated with rotary kilns / vessels can be attributed to misalignment. As such, comprehensive hot kiln alignment significantly contributes towards rotary kilns’ / vessels’ ability to achieve maximum efficiency throughout their service life, whilst eliminating unforeseen breakdowns

Our Hot and Cold Kiln Alignment Services in association with our Routine Inspection Services are tailored to increase plant availability, reduce maintenance related costs and provide more optimal plant efficiency. Some of the consequences of not timeously doing routine or planned alignment are summarised below:

Dickinson Mechanical offers world class Tyre and Roller Grinding Services; conducting in-situ grinding of tyres and support rollers without incurring any kiln downtime. The onsite services include the re-grinding or resurfacing of tyres, trunnions and rollers of various sizes whether floating or fixed. Resurfacing or grinding results in a smoother uniform contact surface between the riding ring and the support rollers, reducing the amount of energy required for rotation

FEECO is a leading manufacturer of highly engineered, custom rotary kilns for processing solids. Our high temperature kilns have earned a reputation for their durability, efficiency, and longevity. We offer both direct- and indirect-fired units

Rotary kilns work by processing material in a rotating drum at high temperatures for a specified retention time to cause a physical change or chemical reaction in the material being processed. The kiln is set at a slight slope to assist in moving material through the drum

Direct-fired kilns utilize direct contact between the material and process gas to efficiently process the material. Combustion can occur in a combustion chamber to avoid direct flame radiation, or the flame can be directed down the length of the kiln

All FEECO equipment and process systems can be outfitted with the latest in automation controls from Rockwell Automation. The unique combination of proprietary Rockwell Automation controls and software, combined with our extensive experience in process design and enhancements with hundreds of materials provides an unparalleled experience for customers seeking innovative process solutions and equipment

Indirect-fired kilns are used for various processing applications, such as when processing must occur in an inert environment, when working with finely divided solids, or when the processing environment must be tightly controlled

Calcination refers to the process of heating a material to a temperature that will cause chemical dissociation (chemical separation). This process is used frequently in the creation of inorganic materials, for example, the dissociation of calcium carbonate to create calcium oxide and carbon dioxide
