Determination of the energy consumption in the processing of local alcoholic beverage, burukutu in selected commercially viable six (6) local government areas in Benue state of Nigeria was conducted. Eighteen cases were randomly investigated within these locations. Mathematical expression was developed to evaluate the energy requirement for each of the seven (7) readily defined unit operations,...

in this study; utilizing the elastic matrix ball has higher processing efficiency and better superficial quality than traditionalgrinding. the diversity of elastic abrasive tool characteristics contact with bend surface results in irregular wear abrasion，and abrasive tool machining status gets complicated. there is no theoretical interpretation of parameters affecting the grinding accuracy. bec...

PURPOSE Grinding with less stress on 3Y-TZP through proper selection of methods and instruments can lead to a long-term success of prosthesis. The purpose of this study was to compare the phase transformation and physical properties after zirconia surface grinding with 3 different grinding burs. MATERIALS AND METHODS Forty disc-shaped zirconia specimens were fabricated. Each Ten specimens wer...

Introduction Due to its tool structure and composition, the grinding operation is considered the best machining process in the manufacture of brittle materials like ceramics. A grinding wheel distributes wear over many cutters and is capable of replenishing itself. However, the condition of the grinding wheel constantly changes as grits wear and chips accumulate in the spaces between grits. The...

Vitreousness and Stenvert kernel hardness characteristics in corn germplasm have been related to in situ and in vivo starch digestibility in lactating dairy cows. Because of the tedious nature of determining vitreousness by manual dissection or conducting Stenvert hardness measurements, it is challenging to screen corn germplasm for animal performance potential. The resistance of corn to grindi...

Ground beef has been implicated as a transmission vehicle in foodborne outbreaks of infection with pathogens such as Escherichia coli O157:H7 and Salmonella. During outbreak investigations, traceback of contaminated beef to the producing facility is often unsuccessful because of inadequate recordkeeping at retail establishments that grind beef products. We conducted a survey in three states par...

BP neural network is applied to control the amount of feed, which is the key problem during the constant-force grinding. Firstly, BP neural network is constructed. Because its convergence is slow and local minimums often occur, the adaptive learning rate is used and certain momentums are added to improve BP neural network. Then the feature parameters in time and frequency domain are picked up i...

In this work, we introduce mechanistic considerations in nonlinear milling of particulate material. We show that the mobility of the powder can have a significant effect on the breakage frequency. During grinding, the change in particle size leads to changes in the mobility of the powder which in turn alters the breakage rate. The mechanistic modeling, being able to accommodate different respon...

Grinding can introduce surface and subsurface damage into ceramics, which may reduce the load-bearing area, and thus the residual strength of a ground component. In this study, the principle of continuum damage mechanics (CDM) is applied to predicting grinding damage for ceramics. A nonlinear thermodynamic constitutive model is established to describe the response of ceramics to complex grindin...

Handling uncertainties for parameters in nonlinear constraints using chance constrained programming (CCP) is not as straight forward as its linear counterparts. A simulation based CCP approach which can be thought as an alternative to handle such a situation, has been adopted in this work while solving a multi-objective optimization problem of an industrial grinding operation under various para...
