Since my daily grind is filled with spinning excel tables, I decided to gift myself with a headache this Christmas: I exported user's emails and purchase dates so that I could build my cohorts and glean some other useful insights. I soon became stuck on which formula to use, how to write my IF statements, running into cyclical redundancies ...

Excel 2016 introduces fast MAXIFS and MINIFS functions. In versions earlier than Excel 2007, array formulas are often used to calculate a sum with multiple conditions. This is relatively easy to do, especially if you use the Conditional Sum Wizard in Excel, but it is often slow. Usually there are much faster ways of getting the same result.

Ball Mill Power Calculation Example #1. A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing ¼ inch (6350 microns). The required product size distribution is to be 80% passing 100 mesh (149 microns). In order to determine the power requirement, the steps ...

In excel, we can find the gridlines under the "VIEW" menu and also in the "PAGE LAYOUT" menu. Gridlines in VIEW menu: The option for gridlines in excel can be found under the View menu, where we can add or remove the gridlines in a sheet which is shown in the below screenshot.

Grinding improves pellet quality by reducing air spaces between particles, allowing closer surface to surface contact for a given volume of feed; i.e., it increases bulk density. Large pieces of any ingredient in a feed formula result in weak spots in the pellet, especially if these are fibrous or bony.

conventional grinding circuits (Bond 1961). Bond's third theory is presented in [1]. By rearranging the formula to [2], the operating work index (Wio) of an existing grinding circuit can be calculated, given known mill power draw, throughput, feed and product size distributions. kWh/t = Power applied per ton of feed to the grinding unit

If the size distribution of particles from a crushing or grinding operation does not approximate a straight line, it suggests that there may have been a problem with the data collection, or there is something unusual happening in the comminution process. The size modulus is a measure of how coarse the size distribution is, and the distribution

Edit a Formula. When you select a cell, Excel shows the value or formula of the cell in the formula bar. 1. To edit a formula, click in the formula bar and change the formula. 2. Press Enter. Operator Precedence. Excel uses a default order in which calculations occur. If a part of the formula is in parentheses, that part will be calculated first.

Grinding – Ex. 1-1 • You are grinding a steel, which has a specific grinding energy (u) of 35 W-s/mm3. • The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2. The motor has a power of 2 kW. • The work piece moves (v) at 1.5 m/min. The chip thickness ratio (r) is 10.

The Excel file is broken up into several sheets to allow the user to tackle the sizing of their pump in a series of logical steps. Sheet 1 consists of user inputs and the main outputs of the Excel program (Figure 6). Sheet 2 provides a quick method to calculate the vapor pressure of a fluid using the Antoine equation. In Sheet 2, several ...

In 2007 Benavente established an empirical correlation for estimating grinding media consumption, based on operational parameters as well as Bond's Abrasion Index. Benavente's correlation showed a substantial improvement in comparison with the results obtained via the use of the Bond Abrasion Index. Carlos Rabanal, from Molycop Perú ...

It is often necessary for CNC people to determine how long machining operations will take to perform. You may be trying to determine which of two or more processes will be used to machine a workpiece - or you may just be wondering how long a machining operation will require to complete. Frankly speaking, the formulae related to calculating machining time are pretty simple to understand …

How to Change the Color of Excel Gridlines. By default, the gridlines in Excel come with a faint gray color. You can change the default color to any of your preferred colors by following the steps below: Click File on the top left corner then go to Options. In the Excel Options dialog box that opens, click Advanced on the left panel.

The calculation formula of CNC machining cycle time is easy, but the situation in the real calculation is much more complex, especially in different operations such as turning and milling. So in this article, follow us to figure out how to calculate CNC machining time for the milling process with a detailed example, then understand the turning ...

grinding volume and power draw would be applied to the grinding of coarse particles. In reality, the mill always contains fines: these fines are present in the ball mill feed and are produced as the particles pass through the mill. For example, when 60% of the solids in a ball mill is coarse, then the

Example using Excel formulas. Example 1: Redo Example 1 of Simple Moving Average using exponential smoothing with α = .4. The result is shown in Figure 1. The formula in cell C4 is =B4 and the formula in cell C5 is =C4+B$21* (B4-C4). The forecast for the next value in the time series is 74.0 (cell C19), by using the formula.

2. Continuous dressing, which is beneficial in large-quantity production in materials that are difficult to machine or grind.The continuous dressing enables the grinding wheel to stay sharp constantly, while maintaining intricate forms. Continuous-dress creep-feed grinding uses an overhead diamond dressing roll to plunge dress continuously during the grinding cycle.
