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 ...

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 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.
