Class Information
Number: 208/426
Name: Mineral oils: processes and products > By treatment of solid mineral, e.g., coal liquefaction, etc. > Including agglomeration, comminution or size-classification of solids
Description: Subject matter wherein a step segregates solids in the stream into different locations, based upon difference in size, causes solid particles to join to provide larger-size particles, or breaks particles into smaller-size particles.
