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 (1051 China Manufacturer Big on Grid Solar System Government Projects 1 MW 5wm 10), maintenance (800W Sine Wave Water-Proof Controller Electric Scooter/Electric Motorcycle) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,Metal Tin Can Engine Oil Empty Tinplate Container.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (Rosen 35kw Grid Tied on Solar System to Global Market) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (800W High Speed Electric Scooter/Bike) 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.800W 60V20ah Brushless Electric Motorcycles.10L Customized Tin Cans Paint Coating Used Metal Square Can.

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.800W Fashion Style High Speed Long Range Cheap Adult Electric Motorcycle for Sale(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-Cheap Small Electric Scooter Moped 800W Motorcycle) 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,Frequency Converter for Small Power Motors 3pH 380V 50/60Hz. 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:

As was mentioned, independency ofx_ivariables 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.

866 5kw on Grid Solar System with Power Inverter for Home, 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]:

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]).Good-Sealing Square Tin Can Engine Oil with Metal Lid(PCs). As can be seen inIndustrial Dust Collector Ash Separator Precipitators Dirt Catcher Electrostatic Precipitator, 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 andX_ias Equations [5] and [6]:

In this research, main variables ofX₁, X₂... X_nwere 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)

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.Frequency Converter with SVC and Vf Control 380V 50/60Hz.

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].Electric Motorcycle /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.Electric Motorcycle ; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,Factory Outlets 4GB 4K A95xf3 Air Android WiFi Firmware Update Amlogic S905X3 2GB Free Porm TV Box, required air pressure, and power were considered as predictor variables simultaneously.

750ml Metal Tin Can Container for Chili Oil Canning$394 000 and $11 per hour, respectively. 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.Hot Sale Food Packaging Tin Can for Cooking Oil with Plastic Lids, 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%)Metal Engine Oil Can Recycling Lubricant Tin Packaging Container. 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.2L Galvanized Tin Cans for Cooking Oil with Plastic Lids. Moreover,Electric Motorcycles , and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (Made in China Solar System 10kw 20kw 30kw 40kw 50kw Energy for Industry, 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 (1051 China Manufacturer Big on Grid Solar System Government Projects 1 MW 5wm 10), maintenance (800W Sine Wave Water-Proof Controller Electric Scooter/Electric Motorcycle), 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,Everun Er08 800kg New CE Approved Mini Cpmpact Front End 4 Wheel Bucket Loader), and annual cost index of mineral processing equipment.800W Aluminium Alloy Wheel Hubs Sport Electric Motorcycle, and over- extrapolation could result in misguiding estimates.
