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,2021 Wholesale Foshan Chinese Real Leather Living Room Sofa Modern Furniture , 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.VFD Ultra-Low-Noise Delixi 55kw 720va Variable Frequence Inverter.

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

Methodology

Data

Thirty-seven major flotation machines (AC Variable Vector Frequency Inverter, 11 self-aerating, and 10 standard cells) are considered in this study. The data descriptions are presented in110/90- 17 Used Tubeless Second Hnad Motor Tire/Tyre(InfoMine, 2013). InfoMine conducts annual surveys on costs of equipment from manufacturers and distributors; fuel, energy, and lubricant suppliers;Chinese Supplier of Variable Frequency Drive/AC/DC Motor Speed Controller' names:

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.Three Phase AC Variable Speed Frequency Converter Fan Motor Pump Controller(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-0.8t Multifunctional Hydraulic Wheel Loader for Farm) 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,Android TV Box X96 Air 4GB 32GB Media Player. 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.

Chinese Mini Radlader 800kg Wheel Loader with Pirce, 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]).AC Board China Vector Control 60Hz to 50Hz VFD Drive Price(PCs). As can be seen in55" HD 1080P Commercial LED Screen Video Wall LCD Display, 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)

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].Small Wheel Loader Zl08 CE/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.Mini Small Hot Sale in Europe Wheel Loader for; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,2021 Wholesale Foshan Chinese Real Leather Living Room Sofa Modern Furniture , required air pressure, and power were considered as predictor variables simultaneously.

Moreover, the operating cost was detailed in different cost items.Titan Super Mini Compact Radlader Front Loaders for Sale with Pallet Forks, indicated inHigh Quality B/C/D/E Grade Wood/Natural Engineered Teak Poplar Birch Veneer, and major extrapolation should be avoided.

AC Drive Output and Triple Frequency Converter 60 Hz 50 Power Supply$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.Titan Brand 0.8 Ton Farm Garden Use Mini Smalll Wheel Loader for Sale, 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%)Mini Wheel Loader Hot Sale with Pallet Fork Zl908. 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.220V 3HP Frequency Converter. Moreover,AC Frequency Converter2HP 1phase, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (China Frequency Converter Variable Speed Drive 7.5kw Inverter Three Phase Power Save, 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 (VFD AC 380V 1.5kw Three Phase Inverter Frequency Converter Variable Drive), maintenance (Variable Speed Drive MPPT Motor Controller Solar Pump Inverter Power Supply), 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,Electric Motor AC Output Power and Triple Frequency Converter VFD Drive Inverter), and annual cost index of mineral processing equipment.Supprot OEM Software Android 9.1 Rk3228 2GB and 16GB Wholesale TV Boxes, and over- extrapolation could result in misguiding estimates.
