Diatomite Processing And Crushing Plant

Diatomite is usually a chalky, sedimentary stone composed mainly of the accumulation of skeletons remaining from primitive diatoms, which are usually single-celled, incredibly tiny aquatic plants. The skeletons are essentially amorphous moisturized or opaline silica sometimes with some alumina.

Diatomite is usually principally utilized to filter food processing products including beer, whiskey, and fruit juice, and also to filter organic liquids which include solvents and oils. Diatomite is also used as a filler in paint, paper, asphalt products, and plastic.Diatomite processing and crushing.

Diatomite processing and crushing

The processing of uncalcined or natural-grade diatomite consists of crushing and drying. Crude diatomite commonly contains as much as 40 percent moisture, in many cases over 60 percent. Primary crushing to aggregate size (normally done by a hammer mill) is followed by simultaneous milling drying, in which suspended particles of diatomite are carried in a stream of hot gases.

Flash and rotary dryers are used to dry the material to a powder of approximately 15 percent moisture. Typical flash dryer operating temperatures range from 70 to 430 C (150 to 800 F). The suspended particles exiting the dryer pass through a series of fans, cyclones, and separators to a baghouse.

These sequential operations separate the powder into various sizes, remove waste impurities, and expel the absorbed water. These natural-milled diatomite products are then bagged or handled in bulk without additional processing.
