Abstract This paper describes the fatigue failure of girth gear manufactured from low alloy cast steel of rotary dryer in a chemical plant. The cracks of T-section web of the girth gear occurred at the end of 25 year working period because of stress intensity factor. Because of normal condition of working surfaces of teeth, spare gear was not thought and repair welding …
case study ‑ finish milling i) The attached graph shows an experimentally derived relationship between the mill exit surface area and the efficiency of grinding. The efficiency of grinding has been expressed as the rate of surface production in m 2 /min/kw calculated simply as the SSA(m 2 /kg) x Output (kg/min) /Power drawn (kW).

The cement industry is the building block of a nation's growth. Infrastructure growth leads to India's growth has resulted in India being the 2nd largest producer of cement in the world. In order to retain this position, the cement industry needs to make sure that their plants run without much interruptions and their equipment function at their ...
Similarly, Domazet et al. developed finite element models in order to study the stress distribution and the location of fatigue cracks in cement mill girth gears. Murugan and Ramasamy [23] used statistical methods to analyse power transformer failures with respect to voltage levels, geographical locations and component failures.
Girth Gear Inspection Deliverables: We provide a complete non-destructive examination of the integrity of the mill gear teeth in accordance with ASTM E2905, for macro-pitting and cracking. We analysis the data as we scan the teeth. If cracks are detected, we provide remedial relief (excavating services) during the inspection site visit.
Case study: Cement plants in Poland help country to reduce landfills In order to comply with the EU directive related to waste management (Directive 2008/98/EC), the Polish Ministry of Environment has set targets (issued in 2011) to reduce the amount of municipal waste going into landfills by 50% in 2013 and by 35% in 2020.
But I found one thing. He gave me several Girth gear/Pinion teeth data of other cement mills. None of them showed common factor after factorization. In this case we have 3 common factors (2, 3, 5) Mill is just 4 months old. Both pinion and girth gear teeth were checked physically and no chip off or wear and tear observed.
Stop action photographs girth gear photographs are an excellent predictive maintenance task that every site can employ without shutting down critical mills, kilns, or dryers. When taken at regular weekly intervals, changes in mill set operation and condition can quickly be …

Wear of gears: A case study at Shiraz Cement Plant ... The ball mill is driven through a girth gear at a speed of 16 rev min −1 and is mounted on the head wall of the ball mill. The girth gear, 6360.6 mm in diameter, is driven by two pinions, each being connected via a gear box and coupling to a 1560 kW electric motor.
An initial case study, reported in Issue 14.3 of this journal (see Reference), of a cement manufacturing plant's coal work station established that CM should be used on the most availability-critical machines (identified through a risk-priority analysis based on the impact of failure on safety and environment, on repair time, on downtime cost ...
Figure 8: Gear blank temperature measurement in degrees F. Figure 9 shows the measured gear tooth bulk temperature (average of the measurement from the thermocouples at 0.008 and 0.018 inch away from the flank surface) as a function of the same three variables, inlet oil temperature, speed, and torque.
For some years now, the foundry Ferry Capitain of Joinville in Northeast France, a manufacturer of girth gears for cement mills, has been offering replacement ball mill girth gears made of ductile cast iron (Fig. 1).Thanks to their short delivery times and the fact that they allow repair welding, these girth gears are a reliable solution in the case of repairs or replacement of …
