The operating costs of breaking coal particles into fine powder, to achieve optimum combustion for the boilers in a power plant, are made up input carry on an energy intensive comminution mechanism and overcome friction losses within pulverising machines. also include cost replacement processing system’s components due wear. This study presents development application attrition test machine tha...

Particle size soft sensing in cement mills will be largely helpful in maintaining desired cement fineness or Blaine. Despite the growing use of vertical roller mills (VRM) for clinker grinding, very few research work is available on VRM modeling. This article reports the design of three types of feed forward neural network models and least square support vector regression (LS-SVR) model of a VR...

It has previously been shown that a bipedal model consisting of a point mass supported by spring limbs can be tuned to simulate periodic human walking. In this study, we incorporated roller feet into the spring-mass model and evaluated the effect of roller radius, impact angle, and limb stiffness on spatiotemporal gait characteristics, ground reactions, and center-of-pressure excursions. We als...

Generally, crash stops are performed to obtain measurement of charge filling and slurry loading. The crash stop involves running the mill under steady state then cutting off all feed streams to the mill as it is being stopped. Sufficient time is required to obtain all the important measurements correctly during the crash stop. The mill filling should be measured at a minimum of 3 points along t...

An open channel flow can change from a supercritical to subcritical flow with a strong dissipative process: a hydraulic jump. Herein some new measurements of free-surface fluctuations next to the jump toe and integral turbulent scales in the roller are presented with a focus on turbulent hydraulic jumps with a marked roller. The results highlighted the fluctuating nature of the impingement peri...

Vertical Coal Mill (VCM) is equipment for grinding and pulverizing coal into micron size. Rotary kilns then use the powders as fuel burners. The VCM has a housing section equipped with lining plate wear tear protector. comprises segments similar thicknesses materials that are severe to due gas-carrying solid particles hitting surface. specific material resilient abrasion required extend operati...

The dispersion state of multilayer graphene sheets in polymers has a strong impact on the properties nanocomposite, and is driven by processing parameters method. Herein, sheet/vinyl ester nanocomposites were manufactured using three-roll mill. roller gaps number cycles varied to study their effect relationship with effective electromechanical nanocomposites. It was found that reducing increasi...
