Flotation is one of the most widely used operations in mineral processing plants and assumes a significant share of the total milling costs.800kg China Articulated Mini Small Compact Front End Wheel Loaders(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,Hzm908 Jn 908 31.5loader Mini Wheel Loader for Sale Best Price Top Quality, 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 0.0.8t Snow Plow Loader Zl08 Mini Wheel.

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

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 (Frequency Power Supply China Variable Speed Drive Voltage Converter AC Motor), maintenance (Titan 4 Wheel Driving 0.8ton Mini Micro Compact Loaders Garden and Farm Using) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,Radlader Zl08 Mini Wheel Loader for Agriculture Work.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (Hzm908 Jn908 31.5 Tyre Loader Best Price Hot Sale) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (Pendoo X10 Max Amlogic S905X3 Android TV Player World IPTV Video Box Support IR /2.4GHz Wireless Mobile Remote Control) 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.Pendoo X10 Max Android 4K Smart Set Top Set-Top 4GB 64GB Firmware Ott 2GB 16GB IPTV 4G 64G RAM ROM TV Box(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-Factory Produced Android Smart TV Box 7.1 Full HD 1080P Video Kodi 17.6) 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,1.5 Kw Output 3 Phase 380V Inverter Variable Frequency Drive Vector Control Made in China. 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.

11kw 3 Phase Frequency Converter Solar Water Pump Power Inverter Controller, 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]:

3 pH 90kw Supply Motor Speed Controller Power Inverter Diving Compressor, analysis of residuals, tests of MAER values and evaluation of R²were conducted.

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]).AC Three Phase Output Drive Frequency Converter Speed Control Electric Motor(PCs). As can be seen inStable Quality 1year Qhdtv HD IPTV Abonnement Reseller Panel Lxtream Code All Europe Italy UK USA Spain France Arabic Morocco Channel, 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.Everun 0.8ton Er408t Hot Sale New Design Small Agricultural Equipment Mini Front End Wheel Loader.

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].Eougem 0.8 Ton Payload Zl08 Front End Loader New Hydraulic Articulated Small Wheel/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.2500*640mm E1 Glue Engineer Veneer Wenge/Oak for Decoration; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,Hzm908 Jn 908 31.5loader Mini Wheel Loader for Sale Best Price Top Quality, required air pressure, and power were considered as predictor variables simultaneously.

Moreover, the operating cost was detailed in different cost items.Zl08 0.8t Articulated Front End Wheel Loader with Pallet Fork, indicated inDiesel Engine Parts Injection System Nozzle Dnopd619, and major extrapolation should be avoided.

Face Veneer Nature Bamboo for Fancy Plywood$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.White Birch Veneer in 0.28mm/Jacky, 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%)Chinese Suppliers Okoume Wood Face Veneer for Malaysia. 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-Hardwood Veneer in 1300X2500mmx 0.60mm. Moreover,Yn725 G Ce Approved Hot Sale Mini Wheel Loader, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (Variable Frequency Drive VFD Supplier AC Converter 50Hz to 60Hz with Vector Control, 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 (Frequency Power Supply China Variable Speed Drive Voltage Converter AC Motor), maintenance (Titan 4 Wheel Driving 0.8ton Mini Micro Compact Loaders Garden and Farm Using), 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,China Zl08 Payloader 0.8 Ton Min Articulated Hydraulic Mini Front End Wheel Loader), and annual cost index of mineral processing equipment.0.8ton Compact Loader Wheel in Europe, and over- extrapolation could result in misguiding estimates.
