Industrial Equipment: Principles, Construction, and Uses
Ball Mill
Principle of Ball Mill
Ball mills operate on the principle of impact and attrition. The mill uses a combination of impact and friction to grind and mix materials.
Principle of Hammer Mill
Hammer mills operate on the principle of impact and attrition. The mill uses a series of hammers to crush and grind the material into a smaller size.
Construction of Ball Mill
- A cylindrical or conical shell made of steel or other materials, which contains the grinding media.
- Steel or ceramic balls, pebbles,
Mastering Data Manipulation with dplyr and reshape2 in R
This document demonstrates data manipulation techniques using the dplyr and reshape2 packages in R.
Introduction to dplyr
dplyr is much faster and easier to read than base R. Here are some of its key functions:
select(): Selects column variables based on their names.filter(): Filters rows based on their values.arrange(): Changes the ordering of the rows.summarize(): Reduces multiple values down to a single summary.mutate(): Creates columns that are functions of existing variables.
Let’s explore these
