coal sizing: small coal granules

By: **terry** On: Wed Dec 14, 2005 6:12 pm

The smallest size selection of coal that seems to be commonly sold is
called "rice coal", but it is still large compared to the actual size of a grain
of rice! What happens to coal particles that really are about the size of
a grain of rice or a pea (roughly 3/16 to 5/16 of an inch across)? I.E., is
there a market for it? I would like to obtain a sample of such coal to try
in a new type of stove.

The next size down is barley, it can be used in place of rice in some stokers or stikers designed to used it. It's roughly the size of large sized sand . The next is commonly referred to as fines, generally used in filtration or power plants.

It's sized many times for filtering. Anthacite filters are superior to most other types of filters because of the way it fractures. They do not clog as easily as say a sand filter.

There's a market for any size no matter what it is.
