MFS File System Functions
mfs_write Function
Function Signature: int mfs_write(int fd, void *buf, size_t count)
This function writes data to a file within the MFS file system. It takes a file descriptor fd, a buffer buf containing the data to write, and the number of bytes count to write.
Functionality:
- Checks if the file descriptor is valid.
- Verifies if the file is opened.
- Adjusts the write count if it exceeds the file’s remaining capacity.
- Calculates the starting position and block number for writing.

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,
