Decreasing static charge of a particulate solid product which causes product to plug metal line used for pneumatic fluidized solid conveyance

摘要

Tendency of smooth particles of a size to pneumatically fluidizing from plugging metal transfer conduits is overcome by changing the geometry a portion, at least 10 weight percent of the particles to jagged, rough or sharp particles, as by grinding and blending the changed geometry particles with the remaining smooth particles.
