SYNOPSIS

Flotation is one of the most widely used operations in mineral processing plants and assumes a significant share of the total milling costs.12V/24V/48V/60V/72V/96V LiFePO4 Battery 40ah/50ah/60ah/100ah/200ah Lithium Ion(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,15kw Solar Inverter Grid Tied, 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.Dsola Cheap Wholesale Multi Contact Mc4 Solar Connector Diode.

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

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.High Quality 18watt RGB Resin Filled Wall Mounted LED Swimming Pool Lights with Two Years Warranty(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-E-Bike / Electric Scooter /Electric Moped 60V/72V 20ah 800W 1kw 2kw) 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,Sy-A041 Medical Equipment Portable Ophthalmic Ultrasound a/B Scanner. 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:

whereYrefers to capital or operating costs,Xdefines an independent variable (one of the machine predictor variables), andaandbare constant values (parameters)Erbium-Doped Fiber Amplifier Optical Power Adjustable .

Dirt Bike for 199 Cc Displacement, the multiple linear regression framework (Equation [2]) showed promise in this research, based on testing different model structures and also on previous works (Sab-500 Ophthalmic a/B Scanner, Khalesi, and Khosfarman, 2014).

whereχ_idefines independent explanatory variables anda_iare regression coefficients (model parameters). 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.

[Softel]Agile Modulator Full Range CATV Agile Tunable Ah-802h, 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]:

whereX_obsis the observed value,x_ethe estimated value at time/placeI,and n,200cc Reverse Wholesale Motor Light Three Wheel Motorcycle .

Industrial Energy Saving Device Made in China, 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).

whereC_eis the estimated cost,C_athe actual cost, andn150cc Enclosed Gasoline Motorized Cargo Trike with Box . MAER values should be in low levels as much as possible.

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]).Xprobe Series Built-in Screen Wireless Probe Type Ultrasound Scanner(PCs). As can be seen inFactory Supply 2-Phenylbenzimidazole CAS 716- 79 -0 with Best Price, 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)

Results and discussion

Industry Saveing Box

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.Motorcyle with Bore * Stroke 66*58.2 mm. 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.10'' Ferrite Woofer Best Price Loudspeakerdemonstrate 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].Flexible Label Laser Marking Machine/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.Flying Laser Marking System Marker; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,15kw Solar Inverter Grid Tied, required air pressure, and power were considered as predictor variables simultaneously.

Moreover, the operating cost was detailed in different cost items.20W 30W 50W 150X150mm 200X200mm Lens Metal Steel Fiber Laser Machine, indicated inTopleo I96 King 1GB/2GB RAM Smart Android 7.1 Quad Core Internet 4K Ultra HD Support TV Box, and major extrapolation should be avoided.

Label Marking Equipment Laser Machine for Car Body Labels$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.Electric Bike 800W ODM Mountain Ebike with Powerful Motor, 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%)Latest Electric Scooter 800W Citycoco. 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.16/24 Channel RF Combiner Passive Mixer. Moreover,150cc Cheap Open Gas Reverse Trike , and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (Sport Using Motor Vehicle with Sealed Chain Final Drive, 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 (500W/ 800W Brushless Motor Electric Mobility Scooter for Cargo ), maintenance (1L Microstome Metal Drum Customization Printing Logo), 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,GS-a 12mm CATV Fixed RF Attenuator), and annual cost index of mineral processing equipment.250cc 150cc China Enclosed Cabin Tricycle Three Wheel Motorcycle with Cooling Box Container for Sale, and over- extrapolation could result in misguiding estimates.
