The Pebble mill is used
Answer & Solution
Correct Answer:
Option
B
The Pebble mill is used to remove the webby hairs from grasses.
The mill is used for removing cob-webby hairs from bluegrass and similar seeds. It has a drum rotating about a shaft, inserted off-centre at opposite ends.
The mill is loaded with seeds and smooth half-inch pebbles and turned at a slow speed until the rubbing action of the pebble rolls the fuzz from the seeds into small round balls.
