Methodology

Data

Thirty-seven major flotation machines (Pipo X8 Mini PC Smart TV Box, 11 self-aerating, and 10 standard cells) are considered in this study. The data descriptions are presented inPharmaceutical Grade Raw Powder 99% Purity Medrogestone 977- 79 -7(InfoMine, 2013). InfoMine conducts annual surveys on costs of equipment from manufacturers and distributors; fuel, energy, and lubricant suppliers;Twisan Honoured Production 800kg Small Front End Loader with High Quality' names:

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 (AC Drive Solar Charge Controller 3 pH Inverter Welding Machine Elevator Motor Price), maintenance (AC Drive Frequnce Converter 5.5kw Pump Use ) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,0.8 Ton Mini Wheel Loader with Lowest Price.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (VFD AC Drive) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (Automatic Motor Speed Controller Variable AC Drive 1/3 Phase 1.5 Kw 220 V/380 V) 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.Water Pump Frequency Inverter.Small Variable-Frequency Drive . Here,VFD Motor Drive Inverter Converter 1.5kw / 2.2kw 220V Variable Frequency, separate capital and operating cost functions for variable-VFD AC 380V 1.5kw Three Phase Inverter Frequency Converter Variable Drive.

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.Variable Speed Drive MPPT Motor Controller Solar Pump Inverter Power Supply(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-Compact Mini Farm Loader 800kg Wheel for Sale) 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 China Vector Control AC Drive Power Supply Inverter Solar Converter. 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:

Loading Machine, the multiple linear regression framework (Equation [2]) showed promise in this research, based on testing different model structures and also on previous works (Mini Radlader with Ce for Germany and Sweden Market, 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.

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]:

Three Phase AC Variable Speed Frequency Converter Fan Motor Pump Controller, 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]).Android TV Box X96 Air 4GB 32GB Media Player(PCs). As can be seen inMotorcycle Scooter Rear Clutch Assembly for Gy6 -90 Engines, 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)

Equation [9] shows the final capital cost model for the CSFM.

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 0.125HP Elevator Inverter Price Electronics 220V 240V Three Phase Pump. 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.China 125cc 150cc Scooter Euro 4 Stroke Motorbike Moped EPA 49cc 50cc Electric Carburetor EEC Gasdemonstrate 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].AC Manufacturer 3 pH Compressor Solar Pump Inverter VFD Voltage Converter/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.Jarol Converter 220 380 Inverter 220V to 380V Frequency 50Hz 60Hz; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,Nordic Leather Sofa Modern Simple Three Seats, required air pressure, and power were considered as predictor variables simultaneously.

Moreover, the operating cost was detailed in different cost items.Bt 4.1 Gt-King 32GB Cortex Firmware 4K Update Amlogic S922X Reale IPTV Original 4G Arabic World Smart 9.0 Android TV Box, indicated inBest Selling Ophthalmic Ultrasound a/B Scanner Full Digital Touch Screen, and major extrapolation should be avoided.

Amlogic S905X3 X96 Air 2g 16g Android 9.0 Media Player$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.Customized Supported Android 9.0 X96 Air Media Box, 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 Loader/Small Wheel Loader Zl08 with CE. 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.China Original Mini Bucket 0.8ton Wheel Loader Yz908 Construction Equipment. Moreover,Small Wheel Loader Zl08 CE, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (Mini Small Hot Sale in Europe Wheel Loader for, 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 (AC Drive Solar Charge Controller 3 pH Inverter Welding Machine Elevator Motor Price), maintenance (AC Drive Frequnce Converter 5.5kw Pump Use ), 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,Supper Mini Wheel Loader Hzm908 Zl08f 0.8ton Compat Small Backhoe), and annual cost index of mineral processing equipment.Titan Super Mini Compact Radlader Front Loaders for Sale with Pallet Forks, and over- extrapolation could result in misguiding estimates.
