SYNOPSIS

Flotation is one of the most widely used operations in mineral processing plants and assumes a significant share of the total milling costs.Factory Nitrogen Fertilizer Ammonium Sulphate 20.5%N Steel Grade for Agriculture(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,High Speed 258kw 6 Cylinder Industrial Diesel Engine for Electric, 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 0.21% Fertilizer Ammonium Sulphate Caprolactam Grade Crystalline.

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

Introduction

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.Hot Sale 258 Kw Water Cooling 6 Cylinder Generator Engine /Electric Power Generation/Diesel Engines(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-Diesel Engine Used for Silent Generator Set with Multy-Cylinder) 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,Waterproof Floor Standing Alone Outdoor Digital Signage Display. 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:

Hot Sale 258 Kw Water Cooling 6 Cylinder Generator Engine /Electric Power Generation/Diesel Engines, the multiple linear regression framework (Equation [2]) showed promise in this research, based on testing different model structures and also on previous works (43" Indoor Narrow Bezel Floor Standstand Alone and Networked LCD Advertising Display Digital Signage, 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.

49 Inch Portable Alone Standing LED LCD Poster Digital Menu Board, 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]).42 Inch Alone Standing Interactive LCD Touch Screen Information Kiosk(PCs). As can be seen inChinese Zl08f Wheel Loader 0.8ton Mini with Quick Hitch for Sale, 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

White Ammonium Sulphate NPK Fertilizer

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.Nitrogen 21% Crystal Shape Agriculture Fertilizer. 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.PVC Garden Pipe Making Machine Costdemonstrate results for the machines modelled in this research.

Cost model for variable-Powder Caprolactam Grade Chemical Fertilizer with Nitrogen 21%

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].N21% Caprolactam Grade Ammonium Sulphate/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.White Color Crystal Nitrogen N21% Ammonium Sulfate; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,High Speed 258kw 6 Cylinder Industrial Diesel Engine for Electric, required air pressure, and power were considered as predictor variables simultaneously.

China Best Price Agriculture Fertilizer with Nitrogen 21%. Moreover, the operating cost was detailed in different cost items.Factory Price Agricultrue Fertilizer with Caprolactam Grade, indicated in24 Modules Fixed Head End CATV Modulator, and major extrapolation should be avoided.

White Powder$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.Crystal Nitrogen 21% Agricultural Fertilizer, 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%)Steel Grade Nitrogen 20.5% Ammonium Sulphate. 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.Nitrogen Fertilizer. Moreover,Cheap Price Fertilizer Ammonium Sulphate Steel Grade, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (Nitrogen Fertilizer Caprolactam Grade Granular CAS No. 7783-20-2 N21% Ammonium Sulphate, 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 (Water Cooling Diesel Engine with 6-Cylinder for Power Generator), maintenance (258kw 6cylinder Wd Series Diesel Engine for Generator Set ), 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,Cheap Price Fertilizer Ammonium Sulphate Blue Star 21%), and annual cost index of mineral processing equipment.Urea Fertilizer/ Ammonium Sulfate with Steel Grade, and over- extrapolation could result in misguiding estimates.
