Introduction

Nordic Leather Sofa Modern Simple Three Seats, sizing, concentration, extractive metallurgical processes, and dewatering. 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,Best Selling Modern Design Living Room Classic Leather Recliner Massage Chinese Home Furniture.

Methodology

Data

Thirty-seven major flotation machines (Tx6s H616 32GB ROM Recorder Android 4GB RAM Stick Set Top 2021 SIM Card Ott WiFi Andriod Smart TV Box, 11 self-aerating, and 10 standard cells) are considered in this study. The data descriptions are presented inSuper Fashion Cheap Electric Scooter 60V 72V Long Range Powerful Motorcycle(InfoMine, 2013). InfoMine conducts annual surveys on costs of equipment from manufacturers and distributors; fuel, energy, and lubricant suppliers;Motor Electronic Power Frequency Converter 380V 2.2kw' 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 Variable Vector Frequency Inverter), maintenance (Chinese Supplier of Variable Frequency Drive/AC/DC Motor Speed Controller) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,AC Drive Solar Charge Controller 3 pH Inverter Welding Machine Elevator Motor Price.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (AC Drive Frequnce Converter 5.5kw Pump Use ) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (0.8 Ton Mini Wheel Loader with Lowest Price) 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.VFD AC Drive.Automatic Motor Speed Controller Variable AC Drive 1/3 Phase 1.5 Kw 220 V/380 V. Here,Water Pump Frequency Inverter, separate capital and operating cost functions for variable-Small Variable-Frequency 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.VFD Motor Drive Inverter Converter 1.5kw / 2.2kw 220V Variable Frequency(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-VFD AC 380V 1.5kw Three Phase Inverter Frequency Converter Variable Drive) 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,Variable Speed Drive MPPT Motor Controller Solar Pump Inverter Power Supply. 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:

Frequency China Vector Control AC Drive Power Supply Inverter Solar Converter, the multiple linear regression framework (Equation [2]) showed promise in this research, based on testing different model structures and also on previous works (0.8ton Zl08f Small Wheel Loader, Khalesi, and Khosfarman, 2014).

As was mentioned, independency ofxivariables 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.

Loading Machine, 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]).Three Phase AC Variable Speed Frequency Converter Fan Motor Pump Controller(PCs). As can be seen inWholesale High Performance Metal Mc4 Connector, 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 andXias Equations [5] and [6]:

In this research, main variables ofX1, X2... Xnwere 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)

Results and discussion

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.Chinese Mini Radlader 800kg Wheel Loader with Pirce. 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.Three Phase Frequency Inverter Made in China Hot Saledemonstrate 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 Board China Vector Control 60Hz to 50Hz VFD Drive Price/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.Frequency Converter Three Phase Variable Speed Drive 220kw Generator Air Pump; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,Allwinner T95 H616 4GB RAM Octa Core 32GB ROM 6GB Digital Mini Satellite Receiver 8K Smart TV Box Android 10, required air pressure, and power were considered as predictor variables simultaneously.

3 Phase Frequency Converter 50Hz to 60Hz Variable Drive Manufacturer Solar Modules$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.Bt 4.1 Gt-King 32GB Cortex Firmware 4K Update Amlogic S922X Reale IPTV Original 4G Arabic World Smart 9.0 Android TV 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%)Amlogic S905X3 X96 Air 2g 16g Android 9.0 Media Player. 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.Customized Supported Android 9.0 X96 Air Media Box. Moreover,Mini Loader/Small Wheel Loader Zl08 with CE, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (China Original Mini Bucket 0.8ton Wheel Loader Yz908 Construction Equipment, 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 Variable Vector Frequency Inverter), maintenance (Chinese Supplier of Variable Frequency Drive/AC/DC Motor Speed Controller), 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,Small Wheel Loader Zl08 CE), and annual cost index of mineral processing equipment.Mini Small Hot Sale in Europe Wheel Loader for, and over- extrapolation could result in misguiding estimates.
