3. Introduction 01

4. What is end runner mill? It is a type of size reduction equipment that is used for grinding and crushing various materials.

And this crushing and grinding occur due to crushing or compression mechanism by a heavy pestle.

Now a days it is typically using in the pharmaceutical, food processing and chemical industries.

6. End-runner mills are the mechanized forms of mortar and pestle-type compression comminution. 

7. Principle 3

8. End runner mill principleThe working principle follows same principle as edge runner mill.In this mill size reduction is done by using heavy weight of steel pestle.It follows the crushing or compression mechanism of size reduction. Shearing stress is also applied during the movement of motor and pestle.

14. WorkingHere is how an end runner mill works:Material is placed in the mortar.The scraper pushes the material into the path of the pestle.The mortar runs at high speed.The pestle is placed in the mortar.The running mortar forces the pestle to move faster.Size reduction is achieved through shearing and crushing.The material is collected and passed through a sieve to obtain the desired size of powder.
