Thirty-seven major flotation machines (Silo Top Pulse Jet Dust Collectors Collector Hopper for Cement, 11 self-aerating, and 10 standard cells) are considered in this study. The data descriptions are presented in5 Wheels Gasoline Cargo Tricycle with Front Cabin(InfoMine, 2013). InfoMine conducts annual surveys on costs of equipment from manufacturers and distributors; fuel, energy, and lubricant suppliers;CAS No.: 63428-84-2 Polyamide PA Resin for Untreated Film' 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 (High Quality Removable Material Warehouse Precision Electronic Weigher with Hand Manual Jack), maintenance (HDPE Water/Gas Supply Pipe Extrusion Line) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,Automatic Tool Changing CNC Router with 9kw Hsd Spindle.

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.HDPE Water/Gas Supply Pipe Extrusion Equipment(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-45cm High Tray Toughened Glass Curved Quadrant Shower Cabin) 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,Bathroom 8mm Glass Full Arc Quadrant Enclosed Shower Door. 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.

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]).NBR Nitril 80 Duro Rubber X Ring /Quad(PCs). As can be seen inChinese Diesel Three Wheel Tricycle with Sunshade, 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.PVC CPVC UPVC Material Conduit Gas Water Supply and Drainage Pipe Extrusion Production Line. 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.Camping Power / RV LiFePO4 Energy Storage Portable Generator 3.8kwh 80A Enjoys 2 Years Warrantydemonstrate 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].Acrylic Film Quadrant Frosted Glass Shower Cubicle with Low Tray /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.Plastic PVC CPVC UPVC Sewage/ Pressure Pipe& Electrical Conduit Cable Pipe/Tube /Single Corrguated Pipe ; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,Single Row Cylindrical Roller Bearing , required air pressure, and power were considered as predictor variables simultaneously.

Dust Collector for Granite Welding$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.Dust Collector Cages Surface Grinding 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%)Dust Collector Hammer Mill Shaker. 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.Gold Dust Collector Cement Filter Bag. Moreover,Low Water Absorption Polymer 610, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (High Impact Strength and Low Water Absorption Resin 610, 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 (High Quality Removable Material Warehouse Precision Electronic Weigher with Hand Manual Jack), maintenance (HDPE Water/Gas Supply Pipe 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,CAS No. 63428-84-2 Good Quality Co-Solvent Soluble Polyamide Resin for Printing Ink), and annual cost index of mineral processing equipment.Plastic PE Pipe Production Line, and over- extrapolation could result in misguiding estimates.
