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 (Lidocaine Hydrochloride CAS 73-78-9 HCl), maintenance (PA Speaker Parts ) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,Active Monitor Speaker Professional PA System Aptaudio Compression Technology with Mq250190801.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (Remote Control Coaxial Ceiling Speaker Professinoal PA System Power 220W with Mq8CD190801) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (Line Array PA Speaker System Stage 12inch Monitor PRO Audio) are associated with both unscheduled repairs and scheduled servicing of all of minor and major components, excluding overhaul actions and lubrication.

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.PRO Audio Speaker 12 Inch Sub PA Passive Speakers(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-PA Speaker Steel Back Plate ) 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,Professional Speaker Power Line-Array Actives Stage Loudspeaker PA System with Vs12. 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:

Outdoor Big Power Karaoke Trolley Loud PA Speaker, the multiple linear regression framework (Equation [2]) showed promise in this research, based on testing different model structures and also on previous works (20dB Gain DJ Mixing Console with MP3 Input , Khalesi, and Khosfarman, 2014).

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.

PA System LED Light Trolley Tws Woofer Speaker Party Audio, 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]).K2 Line Array Rigging Horn Metal Grill Waveguide Flare Sets (PCs). As can be seen inNew Design Source Column Speaker 6X6.5inch B&C Imported Driver Unit PA Line Array Subwoofer with Novi, 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.Cheap 500W Professional Audio Speakers Dual 15 Inch Speaker . 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.Zys Rolling Mill Bearing Four Row Taper Roller Bearings 3810/ 710demonstrate 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].High Power Horn Speaker H3/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.Horn Speaker L-Acoustics Kudo Line Array+ PA System Array Box; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,Professional Two-Way Speaker 4X6.5inch 100dB 600W Line Array PA Audio System with L7, required air pressure, and power were considered as predictor variables simultaneously.

Wireless Professional Rechargeable Portable DJ Karaoke Sound Box Trolley Bluetooth PA Speaker with ED-606$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 0.2.4GHz Wireless Ceiling Speaker PA System, 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%)OEM ODM Public DJ PA Wooden Speaker. 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.Double 12" Line Array Speaker. Moreover,Feiyang 2X6" Private Battery Bluetooth Speaker Fg206-01, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (PA Speaker with Single-Point Angles Regulator , 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 (Lidocaine Hydrochloride CAS 73-78-9 HCl), maintenance (PA Speaker Parts ), 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,12 Inch Stage Subwoofer Home Theater/DJ Sub PRO Audio), and annual cost index of mineral processing equipment.Peq-12A-Active PA Speaker with Class-Ab Mono Amplifier Bluetooth, and over- extrapolation could result in misguiding estimates.
