SYNOPSIS

Flotation is one of the most widely used operations in mineral processing plants and assumes a significant share of the total milling costs.Medical Automatic Ultrasound Bone Densitometer in Low Price(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,Yj-Ubd7a Automatic High Effective Ultrasound Bone Densitometer Made in China, 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.Ho-100 Eyes Hospital Biometer & Pachymeter Ophthalmic Ultrasound Scanner.

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

Introduction

Methodology

Data

Thirty-seven major flotation machines (Chinese Diesel Three Wheel Tricycle with Sunshade, 11 self-aerating, and 10 standard cells) are considered in this study. The data descriptions are presented inCovered Tricycle Carriage Closed Cargo Box(InfoMine, 2013).

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 (5GHz 30dBi Grid Parabolic Antenna ), maintenance (5GHz Dish Parabolic Antenna 29dBi) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,2.4/ 5GHz Dual Band H-Pol Sector Antenna.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (Electric Dirt Bike Zm-Es18 with 500W- 800W Motor) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (5GHz 20dBi Enclosure WLAN Antenna) 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.5GHz 45deg Dual Pol Sector Antenna.5GHz 23dBi Enclosure WiFi Antenna. Here,5GHz Dual Pol Sector Antenna with Enclosure , separate capital and operating cost functions for variable-5GHz 34dBi Dish WLAN Antenna.

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.5GHz 18dBi Dual Polarization Sector WiFi Antenna(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-18W RGB Resin Filled LED Surface Mounted Underwater Pool Light) 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,Poplar Film Faced Plywood Board with Carb Certificate. 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:

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.

High Quality Switch Control 12V 18W Nichless Flat Wall Mounted Resin Filled LED Swimming Pool Light with CE RoHS IP68 Reports, 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.

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]).New Condition Large Capacity Mini Truck Dumper(PCs). As can be seen inChinese Top Local Anesthetic Exporter Bulk Sales Procaine CAS: 51-05-8, 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)

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].China Jiaxing Jarol Frequency Inverter 0.75kw/220V New/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.Portable Laptop Digital Automatic Ultrasound Bone Densitometer; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,Yj-Ubd7a Automatic High Effective Ultrasound Bone Densitometer Made in China, required air pressure, and power were considered as predictor variables simultaneously.

Haiqin Brand 0.8ton Mini Loader . Moreover, the operating cost was detailed in different cost items.Jarol Solar Inverter 5.5kw 3 Phase, indicated inAC Frequency Speed Controller 7.5kw VFD Drives, and major extrapolation should be avoided.

Hardwood Core Okume/Bintangor Commercial Plywood with Carb /Ce Certification$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.Textile Crane Centrifugal 380V Variable Frequency Drive VFD, 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%)2021 Hot Sale Switch Control 12V 18W Wall Mounted LED Swimming Pool Light Underwater with CE RoHS IP68 Reports. 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.AL908 Wood Gripper Wheel Loader with Euro III Engine for Sale. Moreover,Inverter Cabinet VFD Frequency AC Drives 15kw Motor, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (2021 New Design Switch Control 12V 18W Wall Mounted LED Swimming Pool Light Underwater with Edison Chip, 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 (5GHz 30dBi Grid Parabolic Antenna ), maintenance (5GHz Dish Parabolic Antenna 29dBi), 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,12V RGB Resin Filled Underwater Pool Lights with 2 Years Warranty), and annual cost index of mineral processing equipment.loader with excavator grapple wheel mini for sale good quality, and over- extrapolation could result in misguiding estimates.
