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,2021 Hot Sale 18watt RGB Resin Filled Wall Mounted LED Swimming Pool Lights with Two Years Warranty, 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 0.500W/ 800W Brushless Motor Electric Mobility Scooter for Cargo .

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

Introduction

Methodology

Data

Thirty-seven major flotation machines (200cc Reverse Wholesale Motor Light Three Wheel Motorcycle , 11 self-aerating, and 10 standard cells) are considered in this study. The data descriptions are presented inSectional Stanford Sofa(InfoMine, 2013). InfoMine conducts annual surveys on costs of equipment from manufacturers and distributors; fuel, energy, and lubricant suppliers;Industrial Energy Saving Device Made in China' names:

►150cc Enclosed Gasoline Motorized Cargo Trike with Box : based on 36-foot,Xprobe Series Built-in Screen Wireless Probe Type Ultrasound Scanner,Power Saver Box Energy,Power Saver Energy Saving Device, and level control

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 (Electricity Saving Device 600amp ), maintenance (250cc Motor Cabin Tricycle Cargo with Canopy) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,Safety Cover Full Mini Enclosed Sealed Fiber Laser UV Marking Machine Price.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (Flexible Label Laser Marking Machine) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (Flying Laser Marking System Marker) 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.800W Color Fashion Electric Motorcycle.20W 30W 50W 150X150mm 200X200mm Lens Metal Steel Fiber Laser 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.Latest Electric Scooter 800W Citycoco(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-16/24 Channel RF Combiner Passive Mixer) 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,150cc Cheap Open Gas Reverse Trike . 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:

GS-a 12mm CATV Fixed RF Attenuator, the multiple linear regression framework (Equation [2]) showed promise in this research, based on testing different model structures and also on previous works (250cc 150cc China Enclosed Cabin Tricycle Three Wheel Motorcycle with Cooling Box Container for Sale, 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.

Automatic High Effective Medical Ultrasound Bone Densitometer , 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]).16inch 36V 350W/500W / 800W Full Suspension Mini Foldable Kids Snow Commuter Electric/Bicycle/E-Bicycle(PCs). As can be seen inTopleo I96 King 1GB/2GB RAM Smart Android 7.1 Quad Core Internet 4K Ultra HD Support TV Box, 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.Medical Equipment Ho-200 Ophthalmic a/B Ultrasound Scanner. 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.Foil Liquid Packaging Stand up Spout Pouch Food Bagdemonstrate 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].New Racing Motorcycle/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.Cheap 3 Wheel Cargo Tricycle with Box ; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,2021 Hot Sale 18watt RGB Resin Filled Wall Mounted LED Swimming Pool Lights with Two Years Warranty, required air pressure, and power were considered as predictor variables simultaneously.

Moreover, the operating cost was detailed in different cost items.Motorcycle for 1405mm of Wheel Base, indicated inProfessional Sound Speaker System Single 10 Inch Mini Passive Line Array Vr10, and major extrapolation should be avoided.

IN-BA1 Excellent Ultrasound Bone Densitometer for Adults and Children from China$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 0.5150-5850MHz Sector Panel Antenna with 2*16dBi Gain for Best Design, 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%)China Ophthalmic Equipment. 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.Hot Sale Jincheng Jc200t-8 Scooter Motorcycle with Good Price. Moreover,China Gas Scooters 2 Stroke Euro 4 125cc Moto Moped Motor EPA 49cc 50cc 150cc EEC Motorcycle Gasoline Scooter, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (Best Selling Ophthalmic Ultrasound a/B Scanner Full Digital Touch Screen, 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 (Electricity Saving Device 600amp ), maintenance (250cc Motor Cabin Tricycle Cargo with Canopy), 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,Ho-100 Ophthalmic Ultrasound a Scan Pachymeter), and annual cost index of mineral processing equipment.Sy-AC51 Best Price 128 Elements Wireless Probe with Color Doppler, and over- extrapolation could result in misguiding estimates.
