Sorting and processing test overview

1. Optical sorting tests

Foreign and defective product sorting tests are conducted using an optical sorter. Wet materials and seaweed can also be tested.

2. Shape, specific gravity, magnetic force, and wind power tests

These tests are conducted by equipment that sorts by shape, specific gravity, and magnetic force.

3. Wet type surface processing tests

Tests for removing dust and stains are conducted after washing the material surface.

4. Dry type surface processing tests

These tests consist of polishing the material surface with a polishing machine.

ฃต. Sorting and processing tests using test-scale equipment

Smaller scale test equipment is used to perform husking, milling, and sorting tests on small amounts(1-5kg) of sample. This test equipment is especially useful for requests from overseas because it is difficult to import large amounts of sample.
