Abstract
Aluminum chlorohydrate products comprise particles of aluminum chlorohydrate in fractured crystal form, the particles having a basicity in the range of 0% to about 85.6%, and a surface area to weight ratio of about 295 to about 705 m2/kg, inclusive of both endpoints and all numerical values therebetween, where the ratio is measured by laser diffraction. Methods of producing such products are also disclosed.
Claims19
A method for producing aluminum chloride hydrate particles of a desired basicity, said method comprising:
- applying a heated gas stream to a circular mill to establish and maintain a circulating gas stream within the mill at an operating temperature in a range of between 200° F. and 400° F.;
- feeding aluminum chloride hexahydrate crystals into the circular mill, wherein aluminum chlorohydrate particles are formed and the resulting particles are separated based on particle density, the particles having a basicity that is a function of the operating temperature;
- and
- collecting dried aluminum chlorohydrate particles as the particles exit the circular mill.
