Abstract:
The operating speed of rotary maize sheller was optimised for its operation at higher operating speeds in pedalling mode, by conducting a simulation study for three sizes of maize cobs at seven operating speeds. The shelling capacity and shelling efficiency of maize sheller for all categories of maize cobs increased curvilinearly with increase in operating speed up to about 70 rpm. The shelling capacity at a particular operating speed decreased with increase in the maximum diameter of cobs. Operating torque of rotary maize sheller for a given size of maize cobs decreased with increase in opera

Abstract:
At present, ginkgo nut shellers have many problems, such as low shelling rate and high damage rate. To address these problems, a multifunctional ginkgo nut sheller was designed. The equipment had functions for shell breaking, shelling, and separation of shell from the kernel. The influencing factors of the shelling process were analyzed. A three-factor two-level response surface test was conducted, and mathematical models for the response surface were established. The influence of each factor on the operation quality was analyzed, and a combination of parameters was optimized. The experimental

Abstract:
A response surface methodology (RSM) has been utilized for investigating the effects of the speed of shelling, melon seed moisture content and the number of beaters of a developed mechanized centrifugal melon shelling and cleaning machine. The machine shells the melon and then cleans the shelled seed from the shells and other impurities. The experiment was based on a central composite rotatable design (CCRD). The results of the experiments revealed that the highest shelling efficiency of 88.5% was obtained from a combination of a speed of 2300 rpm, moisture content of 15% (w.b) and 20 beaters,

Abstract:
Maize shelling is an important post-harvest operation to separate the grains from its cob. Traditional methods involve rubbing maize cobs against each other, rubbing on stones, or hand method. These methods are labour-intensive, time-consuming, and drudgery-prone. Migration from rural population to cities for better livelihoods has creates labour shortage in rural areas during the peak period of maize shelling. A study was undertaken to design, develop, and evaluate the performance of an electric motor powered maize sheller. It consisted of a frame, feeding chute, cylinder, outer cover, rotor

The study examined the effect of moisture content on maize shelling speed using a manually operated hand Sheller (cone type). Twenty (20) unthreshed maize cob samples (A-J) were used for the study. The samples were analysed in the laboratory for parameters such as weight of samples before and after drying, moisture content and shelling speed. The result indicated that sample J, after sixty nine hours (69<sup>th</sup>) oven drying recorded the lowest moisture content(15.10% wb ) and the fastest shelling speed (0.75 rev. per.

A power operated groundnut sheller that shells groundnut by mechanical shearing and cleans the shelled seeds from chaff pneumatically was designed, fabricated and tested. To increase the shelling efficiency and capacity and to reduce breakage of the seeds as well as reduce power consumption, certain modifications were carried out after the preliminary test. The modifications included a reduction in the shelling speed, rubberisation of the rotating beaters, optimization of the concave slots and adjustments in the blower speed. The modified machine was tested to evaluate its general performance.

Abstract:
Railway wheels and rails do not achieve full wear life expectancy due to the combination of wear, plastic deformation, and surface, subsurface, and deep subsurface cracks. Sixty-seven percent of wheel replacement and maintenance in North America is associated with tread damage [1]. Spalling and shelling are the two major types of wheel tread damage observed in railroad operations. Spalling and slid flat defects occur due to skidded or sliding wheels caused by, in general, unreleased brakes. Tread shelling (surface or shallow subsurface fatigue) occurs due to cyclic normal and traction loads th

Abstract:
Wheel shelling is the cause of a large portion of high impact wheels. The impact loads produced by shelled wheels can have a damaging effect on track components and rolling stock components such as roller bearings. Shelling is the result of accumulated rolling contact fatigue (RCF) on the wheel tread surface. To investigate the specific conditions in which RCF occurs, wheel load environment data was collected from a car with three-piece trucks running in revenue service. This data was analyzed in order to assess the predicted wheel RCF through the use of shakedown theory. An inspection team wa

Abstract Defective railroad wheels in the form of spalling, shelling, slid flat and out-of-round condition impose heavy wheel impact load into railroad track structure and car components, causing millions of dollars damage to Conrail. Allowed to continue in service, these defective wheels occasionally can deteriorate to a cracking condition, eventually breaking to cause costly derailments. As one step in the quality process to implement “Management by Prevention”, Conrail has been installing wheel impact detectors, based on strain gage and microprocessor technology, at various main routes to d

Abstract:
One of the key issues facing rail maintenance crews today is the successful identification and removal of rail corrugations (a sinusoidal, longitudinal rail surface deformation). Typically, rail corrugations are identified through visual inspection (which look for regular surface patterns) or audio methods (which listen for high frequency noise). Once identified, removal is accomplished through rail grinding and consists of running standard “peak-and-plow” grind pattern(s), whereby the corners of the rail are angled upwards to peak the rail, then the top of the rail is ground down (plowed) by
