SKF metal face seals type HDDF are designed for use under severe service conditions at relatively low circumferential offer reliable protection against solid and liquid contaminants as well as leakproof retention of lubricants.

In one embodiment, a source of kaolin ore is reduced in the size to a size distribution of between −2 inches and 10 mesh. The ore is then dried in a dryer at a temperature of not greater than 180° C. to a moisture content of not greater than % by weight to liberate kaolin and calcined at a temperature of not greater than 875° C. to produce metakaolin.

• The process of froth flotation involves crushing and grinding the ore to a fine size – This separates the individual mineral particles from the waste rock and other mineral particles. – The grinding is normally done in water with the resultant slurrycalled the pulp.

Particle Size Analysis Particle size distribution is a property unique to powders and is an important physical property for determining the behavior and nature of powders. For this reason, particle size distribution must be measured when handling powders.
