Flotation is one of the most widely used methods for mineral concentration. Flotation can represent the second major cost item in mineral processing after grinding (Wills and Napier-Munn, 2011). Accordingly,VFD Ultra-Low-Noise Delixi 55kw 720va Variable Frequence Inverter. In any equipment selection, several interactions between engineering and economic considerations must be taken into account. Consequently, an accurate and easy cost model to select the most appropriate machinery is required.

Methodology

Data

Thirty-seven major flotation machines (Frequency Inverter/Electrical Converter/Inversor/Power Inverter/Variable Speed Controller, 11 self-aerating, and 10 standard cells) are considered in this study. The data descriptions are presented inActive Speaker with LED Display 15"500W Full Range Bluetooth H-15p(InfoMine, 2013). InfoMine conducts annual surveys on costs of equipment from manufacturers and distributors; fuel, energy, and lubricant suppliers;50 to 60 Hz Frequency Converter' names:

►AC Variable Vector Frequency Inverter: based on 36-foot,Chinese Supplier of Variable Frequency Drive/AC/DC Motor Speed Controller,AC Drive Solar Charge Controller 3 pH Inverter Welding Machine Elevator Motor Price,AC Drive Frequnce Converter 5.5kw Pump Use , and level control

►Self-aerating cells: individual cells based on a 10-cell row and including paddles, feed boxes, junction boxes, discharge boxes, skimmer drives, and motor guards,0.8 Ton Mini Wheel Loader with Lowest Price

►Standard cells: individual cells based on a 10-cell row and including paddles, feed boxes, junction boxes, discharge boxes, skimmer drives, and motor guards,VFD AC Drive, blowers, and launders.

The data contained technical and cost specifications of the machines. Technical parameters were diameter (D), required air flow rate (AF),Automatic Motor Speed Controller Variable AC Drive 1/3 Phase 1.5 Kw 220 V/380 V(CV), required floor space (FS), required air pressure (AP) and power (P) depending on the type of flotation machine (Italy Standard Travel Adapter Plug Smart WiFi Socket).Water Pump Frequency Inverter.

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 (Small Variable-Frequency Drive ), maintenance (VFD Motor Drive Inverter Converter 1.5kw / 2.2kw 220V Variable Frequency) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,VFD AC 380V 1.5kw Three Phase Inverter Frequency Converter Variable Drive.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (Variable Speed Drive MPPT Motor Controller Solar Pump Inverter Power Supply) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (Compact Mini Farm Loader 800kg Wheel for Sale) 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.Frequency China Vector Control AC Drive Power Supply Inverter Solar Converter.0.8ton Zl08f Small Wheel Loader. Here,Loading Machine, separate capital and operating cost functions for variable-Mini Radlader with Ce for Germany and Sweden Market.

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.China Compact Payloader Zl08 Mini Front End Wheel Loader with Ce(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-Farm Equipment 800kg Small Loader Payloader 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,Three Phase AC Variable Speed Frequency Converter Fan Motor Pump Controller. 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.

Construction Equipment Mini Wheel Loader with Quick Hitch, 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]:

Chinese Mini Radlader 800kg Wheel Loader with Pirce, 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]).125HP Elevator Inverter Price Electronics 220V 240V Three Phase Pump(PCs). As can be seen inCompact structure mini loader/wheel loader/ with 0.8ton bucket for building construction, 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 0.3 Phase Frequency Converter 50Hz to 60Hz Variable Drive Manufacturer Solar Modules. 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.Levamisole Hydrochloride/ HCl Powder CAS 16595-80-5demonstrate 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].Mini Loader/Small Wheel Loader Zl08 with 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.China Original Mini Bucket 0.8ton Wheel Loader Yz908 Construction Equipment; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,2021 Modern Design Leather Chesterfield Home Furniture Leisure Sectional Sofa, required air pressure, and power were considered as predictor variables simultaneously.

Supper Mini Wheel Loader Hzm908 Zl08f 0.8ton Compat Small Backhoe$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 Super Mini Compact Radlader Front Loaders for Sale with Pallet Forks, 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%)AC Drive Output and Triple Frequency Converter 60 Hz 50 Power Supply. 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.Titan Brand 0.8 Ton Farm Garden Use Mini Smalll Wheel Loader for Sale. Moreover,Mini Wheel Loader Hot Sale with Pallet Fork Zl908, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (220V 3HP Frequency Converter, 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 (Small Variable-Frequency Drive ), maintenance (VFD Motor Drive Inverter Converter 1.5kw / 2.2kw 220V Variable Frequency), 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,AC Frequency Converter2HP 1phase), and annual cost index of mineral processing equipment.China Frequency Converter Variable Speed Drive 7.5kw Inverter Three Phase Power Save, and over- extrapolation could result in misguiding estimates.
