摘要： A method of producing a range of diatomaceous earth filter aids having selectable permeabilities and less than about 1 percent by weight total crystalline silica. The method includes milling diatomaceous earth ore to a size range of between about 100 micrometers and about 1400 micrometers; calcining the milled diatomaceous earth in a calciner; and milling the calcined diatomaceous earth in an adjustable milling and classification system to produce diatomaceous earth filter aids. Systems to implement such methods and compositions produced by such methods are also described.

摘要： A method of producing a range of diatomaceous earth blended filter aids having selectable permeabilities and less than about 1 percent by weight total of crystalline silica and less than about 0.1% by weight total of respirable crystalline silica. The method includes milling diatomaceous earth ore to a size range of between about 100 micrometers and about 1400 micrometers; calcining the milled diatomaceous earth in a calciner; milling the calcined diatomaceous earth in an adjustable milling and classification system to produce diatomaceous earth filter aids, and blending the diatomaceous earth with expanded perlite to form a low bulk density and low solubility filter aid.
