### Bond Impact Crushing Work Index -Procedure and Table of

Sizing a crusher can be done reliably calculated thanks to the Impact/Crushing Work Index and the testwork research done by Fred Chester Bond and his 1952 paper. According to Bond’s Third Theory of Comminution, the work/energy input is proportional to the new crack tip length created during particle breakage and equivalent to the work represented by the product – the feed. A crude test

### How to use the Excel AGGREGATE function | Exceljet

The AGGREGATE function returns the result of an aggregate calculation like AVERAGE, COUNT, MAX, MIN, etc. A total of 19 operations are available, and the operation to perform is specified as a number, which appears as the first argument in the function. The second argument, options, controls how AGGREGATE handles errors and values in hidden rows. See tables below for all available options.

### What are aggregate tables and aggregate fact tables?

Aggregate tables, in general, are simply database tables that contain aggregated values. OK, I admit it: that answer is accurate but useless. So let's try again, and this time we'll use a fact table as an example. Imagine that you have a fact table like this in which the granularity is date, product and customer:

### Crusher Wikipedia

Its way of working consists on a bucket with two crushing jaws inside, one of them is fixed and the other one moves back and forth relative to it, as in a jaw crusher. They are manufactured with a high inertia power train, circular jaw movement and an antiestagnation plate, which prevents large shredding pieces from getting stuck in the bucket's mouth, not allowing them to enter the crushing
