Abstract
A rotary drum-type magnetic separator includes a first rotary drum on which a plurality of magnets are disposed and separates unnecessary objects from a used coolant liquid. A second rotary drum on which a plurality of magnets are disposed is provided before the first rotary drum in a direction in which the used coolant liquid flows separately from the first rotary drum. The second rotary drum includes an outer tube and an inner tube. A scraper which scrapes off the unnecessary objects attached to the second rotary drum is connected to a bottom member which forms a flow path below the first rotary drum.

A rotary drum-type magnetic separator which separates magnetic substances from a used coolant liquid, comprising:
- a first rotary drum on which first rotary drum magnets are disposed;
- a second rotary drum on which second rotary drum magnets are disposed;
- and
- a scraper configured to scrape off the magnetic substances that are attached to the second rotary drum,
- wherein the used coolant liquid is flowable along a flow path in a manner that the used coolant liquid flowing in the flow path comes into contact with the second rotary drum before contacting the first rotary drum, the first rotary drum is after the second rotary drum along the flow path.
A rotary drum-type magnetic separator which separates magnetic substances from a used coolant liquid, comprising:
- a first rotary drum on which a plurality of magnets are disposed;
- a second rotary drum that is situated before the first rotary drum in a direction in which the used coolant liquid flows such that the magnetic substances are adsorbed to each other;
- and
- a scraper configured to scrape off the magnetic substances that are attached to the second rotary drum,
- wherein the second rotary drum includes a strong magnetic portion that has a magnetic force and a weak magnetic portion that has a magnetic force weaker than the magnetic force of the strong magnetic portion, and
- wherein the strong magnetic portion and the weak magnetic portion are at equal intervals on a peripheral surface of the second rotary drum.
