• Summary

A o ut F irst Am erican

• Founded in 1995, First AmericanScientific Corporation (FASC) isindustrial equipment manufacturer andprovider of innovative systems thatincrease profitability and reduce theenvironmental impact of materialsprocessing.

• The KDS Micronex™, FASC’s patentedgrinder-dryer, efficiently andeconomically processes a wide variety of raw materials and wastes into fine, drypowders.

• KDS stands for KineticDisintegration System. The KDSMicronex™ is an high volumegrinder that dries WITHOUT needing any heat input.

• No heat is needed because theforces causing size reduction alsodry the material.

• KDS Technology uses LESS totalenergy than conventional dryingand grinding combined.

Benefits of the KDS Micronex™

Simplifying on-site grinding and dryingoperations into a single compact, andeasy-to-operate system that has lowinitial and operating costs

Creating high-quality, dry, virtuallypathogen-free powders that have valueas industrial feedstocks, fuels, fertilizersand animal feeds.

Reducing transportation and disposalcosts by reducing moisture

Raw material is dropped intothe throat of the mill

The KDS MICRONEXTM Process Flow

An air-lock gate reduces dustand eliminates blow-back


Material moves to the Torus andis subjected to repeatedviolent collisions with thespinning rotor and strike plates


Material is fractured andpathogen destruction occurs

Water vapor and waterdroplets are released duringthe fracturing process


The classifier allows finishedproduct to pass through to thecyclone and forces oversizeparticles to be reprocessed


Cyclone

Air containing moisture isseparated and removed fromthe system.

Processed solid material isoutput from the bottom of the cyclone

• KDS Micronex™ is the onlymachine known to us that canproduce sub-micron glass powder,in bulk quantities.

• Powdered glass can be used as areplacement for silica fumecement an brick manufacture or as a filler for various other coatings.

• Patented process mechanicallyseparates gold and avoids the use of toxic chemicals.

• Gold stays in KDS chamber when goldore (quartzite) is ground to 30 microns.

• Waste rock is conveyed out of KDS.

• Research under way to improveoperating efficiencies

Zeolite, Glacial Clay, Coal

• Two kinds of Paper Sludge –Primary/Secondary (P/S) Sludgeand De-inking Sludge

• P/S Sludge comes from wastewater from paper pulp-making. Hasbacteria. MC = 80 %

• Deinking sludge results fromrecycled paper manufacturing. It is25% clay (kaolin). MC = 50 %


Paper Sludge

• Both kinds contain burnable fiber,but are too wet to burn on grate or in dust burners.

• Both can be directly applied asfertilizer, but this can lead torespiratory problems and water pollution.

• Paper Sludge is usually landfilled at$17-35/mT + $0.1/mT/kmtransportation cost.


Paper Sludge Comparison

• Drying sludge reduces landfill costs.

• Dried paper sludge can be used tomake sound-absorbing material,cattle-bedding.

• Dried paper sludge is burnable ingrate or dust burner.

975 kJ/kg is only 42 % of the latent heat of water!

Drum Dryer would need 3700 kJ/kg of water.


Glacial Clay

• FASC has processed Oyster Shellswith excellent results.

• Fine, bone-dry powder is produced.

• Up to 3 TPH of possible.


Oyster Shells

Sub-micron glass powder can bemade cheaply in large quantities

Limestone and gypsum caneffectively be ground to solutiongrade

KDS dries deinking sludge with 74 %LESS energy than drum dryers
