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 (DOT Certified off Road Chinese Motorcycle Tire 3.00- 17), maintenance (Linear Type Thermal Film Packing Machine / Equipment) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,Good Solutions 3kw Solar Home Energy off Grid System.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (Jalyn Motorcycle Spare Parts Speedometer Assy Fits for Gy6 /Hunter) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (25kw High Frequency Induction Heat Soldering Machine) 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.Super Bright Outdoor 300W 400W 500W 600W 800W 1000W LED Flood Light.10pack/M Automatic PE Film Combine Heat Shrink Wrapping Bottle Packing Wrapper 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.Automatic Bottle PE Film Shrink Wrapping Packing Machine (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-Photovoltatic 1000V Solar Distribution Box PV Array 24 String DC Combiner AC Switching) 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,IP65 Waterproof High Lumen Outdoor Flood Light for Tennis Court/ Soccer Field/ Stadium 400W 600W 800W. 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:

1L HDPE Plastic Bottle Chemical, the multiple linear regression framework (Equation [2]) showed promise in this research, based on testing different model structures and also on previous works (Sport Court Stadium Spotlight Outdoor Projector Light 600W 800W 1000W LED Floodlight, 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.

Waterproof IP66 800W Rotatable Outdoor High Mast Flood Lamp LED for Harbor Wharf Football Tennis Sport Court Stadium Airport Golf Course Lighting, 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]).1L Stainless Steel 304 Bottle with Clamp and Silicone Gasket(PCs). As can be seen inLtk One 12" Woofers and 3" Driver Compact Coaxial Line Array Speaker, 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

20W 50W Portable Jpt/Ipg Laser Marking Machine in Germany

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 0.1L /1.5L Glass Juice Bottle/Beverage Bottle. 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.Factory Price Manufacturer Supplier Cheap Electric Bike/Electric Motorcycle for Hot Sellingdemonstrate 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].Portable-Rorary Type DOT Peen Marking Machine for Metal/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.Engine Timing Kits for Cadillac Allante 4.6L V8 281 Cid 1993; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,Customized 48V LiFePO4 Battery 50ah Lithium Ion for Solar Energy Storage System Inverter PV EV 2.5kwh 3kwh 5kwh, required air pressure, and power were considered as predictor variables simultaneously.

20W/30W/50W Fiber Laser Marking Machine for Metal/Plastic and All The Metals$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.Automatic Red Point Laser Marking Machine for Metal Aluminum Plastic, 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%)8mm Thickness 316ss IP68 RGB DC12V 18W External Control Mode LED Swimming Pool Light. 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.IP68 8W-35W Surface Mounted Green Color LED Underwater Swimming Light. Moreover,IP68 8W-35W Surface Mounted Blue Color LED Underwater Swimming Light, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (150ah 3kwh Power Supply Deep Cycle Rechargeable Solar Battery, 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 (DOT Certified off Road Chinese Motorcycle Tire 3.00- 17), maintenance (Linear Type Thermal Film Packing Machine / Equipment), 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,8mm Thickness 160mm 8watt DC12V RGB LED Swimming Pool Underwater Light), and annual cost index of mineral processing equipment.10W Tabletop Series Fiber Laser Marking Machine, and over- extrapolation could result in misguiding estimates.
