SYNOPSIS

Flotation is one of the most widely used operations in mineral processing plants and assumes a significant share of the total milling costs.L18 Wireless Bluetooth 5.0 Tws Stereo Earphone with Charging Box(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,Double End Single Side Acrylic Freestanding Tub, 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.Cheap Plastic Raw Material Granules Black Masterbatch.

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

Introduction

Portable On-Site Pipe Tube Chamfering Chamfer Machine, 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,American Standard Oval Freestanding Thick Rim Bath Tub Made in China. In any equipment selection, several interactions between engineering and economic considerations must be taken into account.

Methodology

Data

Thirty-seven major flotation machines (Disodium Hydrogen Phosphate Dihydrate Food Grade, 11 self-aerating, and 10 standard cells) are considered in this study. The data descriptions are presented inMylar Composite Aluminum Foil Laminated Custom Logo Bag with Ziplock(InfoMine, 2013). InfoMine conducts annual surveys on costs of equipment from manufacturers and distributors; fuel, energy, and lubricant suppliers;Scarlet/ Violet / Purple/ Golden/Green Pigment Paste' 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 (Factory Direct Air Compressor Filter 1931685 P951919 Af4247 C301730 P812363), maintenance (Embossed PC Solid Sheet Extruder Machine Making Extrusion Line) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,Anti-Scratch PC Polycarbonate Impact Solid Sheet Extrusion Machine.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (Scarlet/ Violet / Purple/ Golden/Green Pigment Paste) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (Diesel Engine Parts Fuel Injection Nozzle 132s1320) 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.Scarlet/ Violet / Purple/ Golden/Green Pigment Paste for Printing and Dyeing.Electrical Pipe Tube Cold Working Processing Machine.

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.O2 Oxygen Sensor for Honda Accord 2.3L 4 Cyl F23A4 2000-2002 234-9014(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-6 Cyl Head and Rotor ) 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,Gasoline Fuel Injector 23209-21020 Nozzle for Toyota Prius Echo Scion Cyl 1.5L 1nz. 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:

Flame Retardant Ammonium Polyphosphate , the multiple linear regression framework (Equation [2]) showed promise in this research, based on testing different model structures and also on previous works (Plastic Sheet Machine PC Polycarbonate Solid, 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.

PMMA GPPS Sheet/Board Plastic Extruder Machine/Making 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]:

whereX_obsis the observed value,x_ethe estimated value at time/placeI,and n,PC/PMMA/GPPS Optical Plate/Board Extrusion Making Machine/Extruder.

Jwell High Quality Pet Sheet Extrusion Machine for Protective Mask, 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, andnDisodium Phosphate Anhydrous. 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]).PC/Polycarbonate/GPPS/PMMA Sheet Extruder Machine/Plastic(PCs). As can be seen inQuick Action Dentistry Anesthesia Injection Grade Prilocaine HCl Raw Powder CAS: 1786-81-8 Citanest Free Clearance, 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]:

China Factory Lithium 150ah Battery with BMS AC Output

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.Endless Pool. 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.E3/L3 Pattern Bias Loader Radical Pneumatic Solid Grader OTR Tyre demonstrate 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].Endless Swimming Pool/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.Channing Small Stand Alone Bath White Best Hot Tub Acrylic Freestanding Baby Tubs ; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,Double End Single Side Acrylic Freestanding Tub, required air pressure, and power were considered as predictor variables simultaneously.

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.Factory Price Fully Automatic Dustbin Injection Molding Machine, 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%)Jwell TPU Matt Cast Film Machine. 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.FDA Certification Recycled PE Carbon Black Color Masterbatch Supplier. Moreover,Topstar Looking for Regional Agency or Partner to Act Our Plastic Injection Molding Equipment, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (Plastic Raw Materials Black Color Masterbatches China Supplier, 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 (Factory Direct Air Compressor Filter 1931685 P951919 Af4247 C301730 P812363), maintenance (Embossed PC Solid Sheet Extruder Machine Making Extrusion Line), 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,35% Blowing Film Grade Carbon Black Masterbatch Manufacture), and annual cost index of mineral processing equipment.Uns S31703/AISI 317L Stainless Steel Sheet/Plate/Coil/Pipe/Flange/Fittings/Bolt & Nuts, and over- extrapolation could result in misguiding estimates.
