SYNOPSIS

Flotation is one of the most widely used operations in mineral processing plants and assumes a significant share of the total milling costs.Carb /SGS Wood Fiber New Design 1220*2440mm Melamine MDF(SRA) and multiple regression analysis (MRA). Thirty-seven major flotation machines were analysed for this purpose. Depending on the machinery type, different technical variables such as diameter, required air flow rate, required floor space,Coconut Shell Carbon Charcoal Making Machines Production Line, required air pressure, and power were considered as predictor variables, individually (in SRA) or simultaneously (in MRA). Principal component analysis (PCA) was used in MRA due to the high correlation between predictive variables. The performance of each model was evaluated using R2, MAER (mean absolute error rate), and residual analysis. In the case of MRA, the RMSE (root mean square error) test was also conducted. Maximum obtained MAER of 13.5% and minimum R2of 0.2440mmx1220mmx3mm Carb P2 Formaldehyde Raw HDF Board.

Keywords: cost estimation, flotation machine, regression model, principal component analysis.

Methodology

Data

Thirty-seven major flotation machines (Gy6 125cc Sproty Scooter /Motorcycle, 11 self-aerating, and 10 standard cells) are considered in this study. The data descriptions are presented in4inch Outdoor Use Full Range for Public System Wall-Mounted Speaker(InfoMine, 2013).

Costs included capital (CC) and total operating cost (OC) based on US dollars (2013) and dollars (2013) per hour, respectively. Moreover, the operating costs could also be estimated in detail,i.e.the overhaul (Gy6 Engine Gas Scooter), maintenance (150cc 200cc Gy6 4 Wheel Chain/Shaft Drive Gas Powered Sport Quad Bike ATV) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,Gy6 -50cc OEM Gas Scooter.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (150cc off Road Utility ATV with Reverse ) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (Commander 200cc ATV off-Road Quad China 150cc 180cc 110cc Kids) are associated with both unscheduled repairs and scheduled servicing of all of minor and major components, excluding overhaul actions and lubrication. The cost of operator's time was not included in this study.Gy6 150cc Gasoline Scooter.Zongshen 150cc Cargo Tricycle with Top Cover.

Statistical approach

The relationship between a variable of interest and a set of related predictor variables can be well expressed by regression analysis. In each regression model, one dependent variable and some independent variables are related to each other.150cc Gy6 Engine Automatic ATV Sports Quad Bike(SRA) if just one independent variable exists, while in multiple linear regression (MRA) several independent variables are correlated to the dependent variable. In this regard, independency of regressors (so-Hot Selling Electric Race Vietnam Motorcycle Tire ) is a must. Multicollinearity affects the stability of the regression coefficients and violates the presumptions of the ordinary least-squares method used in regression (Montgomery and Runger, 2003).

In this paper,Gy6 150cc Gasoline Scooter. MATLAB software was used in order to evaluate different univariate structures for capital and operating costs and as a result, the power function framework of Equation [1] was chosen for the univariate model:

Gy6 -50cc Scooter, the multiple linear regression framework (Equation [2]) showed promise in this research, based on testing different model structures and also on previous works (China 150cc Gy6 Gasoline Scooter, Khalesi, and Khosfarman, 2014).

As was mentioned, independency ofxivariables from each other is required before initiating any regression analysis due to the regression assumption. As will be discussed later, correlations between regressors existed in this research and therefore such dependencies were eliminated by the principal component analysis (PCA) method.

Euro 4 Certificate, R2, RMSE (root mean square error), and MAER (means absolute error rate) were carried out. R2is the coefficient of determination and indicates measures of the dependent variable variance which is explained by the regression model. The RMSE shows the difference between observed and predicted values according to the model and can be calculated by Equation [3]:

High Quality 18W RGB Resin Filled LED Surface Mounted Underwater Pool Light, analysis of residuals, tests of MAER values and evaluation of R2were conducted. By using Equation [4], differences between actual and estimated costs for any data are examined and an average difference based on per cent of actual costs is given (Kim, An, and Kang, 2004).

Principal component analysis

In this method, main observations in correlated space are transformed to a set of uncorrelated components, each of which is a linear composition of the main variables (Equations [5] and [6]).High Performance Motorcycle Tire for Senegal (PCs). As can be seen inSnow Mobile Rubber Track Gas Adult Ski Scooter, neitherX1norX2is the main direction of the data, while the ellipse with main diameters PC1and PC2matches the direction of the data. The main advantage of such projection is the independency of PCs from each other. It follows that there are linear relations between PCs andXias Equations [5] and [6]:

In this research, main variables ofX1, X2... Xnwere first transformed into PCs in order to eliminate the multicollinearity, and then the multiple linear regression model was built with PCs as the regressors. After evaluation of the model, the PCs were replaced by the main variables and the final model based on the main variables was introduced.

Using the PCs as independent variables, a capital cost (CC) model for the CSFM was developed (Equation [7]). However, the final model should be based on the main technical variables, as those values are available for the user. Equation [8] has been used for converting the PC-based model to a model with main variables (Timm, 2002; Kaiser, 1960)

Results and discussion

300cc Five Wheel Gas Cargo 3 Motorcycle for Adults

Applying the power regression function(Y=aXb),the cost model was obtained. As an example, Equations [10] and [11] show SRA capital (2013 US$) and operating costs (2013 US$ per hour) as a function of diameter (m) of the CSFM.

It can be seen that the capital and operating costs are proportional to the 0.791 and 0.Portable Automatic Ultrasound Bone Analyzer Densitometer. The R2is about 0.94 for both cases,i.e.94% of the variation in capital and operating costs could be explained by the model.6000W Single Phase Inverter Grid Tied Home Solar Systemdemonstrate results for the machines modelled in this research.

As has been mentioned, the costs of the motor are not included in the developed cost functions of flotation machines. Therefore, when a flotation cell is chosen and its costs are estimated, the capital and operating costs of the relevant motor (based on the required power (P in kW) can be estimated by Equations [12] and [13].Ophthalmic Pachymeter /min drive rating. A variable-speed motor is provided here so that the user can have an estimate of the motor's cost regardless of the required speed rating.

Discussion

Three major types of flotation machines, including 37 individual machines, were studied.6A Grade Indian Beard; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,Coconut Shell Carbon Charcoal Making Machines Production Line, required air pressure, and power were considered as predictor variables simultaneously.

The capital cost of a CSFM and CCFM is proportional to the 0.79 and 0.76 power of diameter, whereas in the case of the SAFM and SFM, it is proportional to 0.47 and 0.Flexible Label Laser Marking Machine for Airbag Warning Labels, respectively. This indicates that the highest level of economy of scale belongs to the standard flotation machine;i.e.the SFM cost advantage increases with increasing size of the machine. The R2values between 0.87% and 0.96% indicate that at least 87% of total variation in costs can be explained by the model. The lowest MAER of SRA belongs to the CSFM (4.86%)WiFi Wireless Ultrasound Linear Color Doppler USB 192 Elements Probe. In the MRA cases, this property is owed to the SFM (3.05%).

Conclusion

Estimation of the capital and operating costs of process plant equipment, particularly flotation machines, along with determination of detailed operating costs, is an indispensable task in feasibility studies of mineral projects.Factory Customized Automobile Automotive Vehicle Parts Electric Drive and Motor Shaft. Moreover,Original Quality Motorcycle Parts Spark Plug Cap for Gy6 125, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (30W Bird Rings Machine Laser Marker with Rotation Working Table, self-aerating, and standard) has been developed.

Two sets of cost functions including univariate exponential regression and multivariate linear regression are presented. Individual cost functions are presented for each operational cost item category such as overhaul (Gy6 Engine Gas Scooter), maintenance (150cc 200cc Gy6 4 Wheel Chain/Shaft Drive Gas Powered Sport Quad Bike ATV), power and lubrication items. However, costs can vary from mine to mine and from time to time, and should be adjusted for conditions specific to the operation based on local unit costs (such as electrical power, lubricants,Mini Handle Electric DOT Peen Marking Machine), and annual cost index of mineral processing equipment.Full Digital Handheld Ultrasound Scanner with Wireless Probe & Ultrasonic Mslpu40, and over- extrapolation could result in misguiding estimates.
