Agitator Arms: Following arms can be installed in either stainless steel or plastic-sleeved agitator shafts: ■ Tool steel (hardened) ■ Stainless steel (440C) ■ Colmonoy ® -faced stainless steel ■ Plastic sleeved, steel reinforced ■ Transformation toughened alumina sleeved ■ Polyurethane coated ■ Silicon nitride sleeved ■ Tungsten carbide sleeved ■ Zirconium oxide sleeved ■ Specially configured "L" arms available in stainless and tool steel ■ Special bottom-lifter arms Conversion Assembly: This assembly is designed to convert a S-1 to a Circulation-type "Q" system. The assembly includes a top discharge chamber, grid plate with slotted grids, axial seal, and shaft impeller. Also included is a new agitator shaft for the required six agitator arms. A pump and holding tank are also required (see photo upper right on page 11). Covers: ■ 2-piece aluminum, stainless steel or plastic ■ 1-piece stainless steel with simplified mechanical shaft seal, with gas inlet/ outlet and charging port ■ 1-piece stainless steel with floating Teflon seal and charging port ■ 1-piece stainless steel with brush seal and charging port ■ 1-piece stainless steel with floating seal, charging port, and vent for grinding in liquid nitrogen (cryogenic grinding) Bottom Valves: ■ Stainless steel ball valve (standard) ■ Dry grind metering valve (cannot seal for inert gas use) (standard for dry grind) Discharge Grids: ■ Hardened tool steel ■ Stainless steel ■ Plastic ■ Zirconium oxide ■ Tungsten carbide-faced stainless steel Grids come with a choice of the following openings: 1/8", 3/32", 1/16", 1/32", or 1mm, .5mm, or .4mm Special: ■ Stainless steel sample vessel for discharge under inert gases complete with site glasses ■ Adapter for S-1 to hold HD-01 750cc or 1400cc tanks (includes shaft reducer to enable standard HD-01 shafts to fit S-1 coupling) ■ Special top assembly to convert to a Circulation ("Q") Attritor Pumps For Circulation: Same as 01 Series ■ Air driven, explosion-proof ■ 110V, 1/4 HP, variable speed ■ 110V, 1/4 HP, variable speed, explosion-proof Portable Stand w/Heavy Duty Casters: Available for use with S-1 Attritor Many accessories are available for the S-1. With the basic mill, one can equip it for metal-free grinding, for grinding under inert gases, and for cryogenic grinding. Most parts are interchangeable. Each size tank has its own arm sizes but the 1 gallon, 1-1/2 gallon and 2-1/2 gallon tanks share the same shaft size. For all covers, one size fits the 1-1/2 gallon and 2-1/2 gallon, and one size fits the 1/2 gallon and 1 gallon. Bar grids are interchangeable for tanks made from the same material. One size bar grid fits the 1-1/2 and 2-1/2 gallon tanks, and another size bar grid fits the 1/2 and 1 gallon tanks. A pump is available to duplicate the circulation process in the production-based Attritor. There is also an adapter available to allow the use of the HD-01 series tank sizes on the S-1. There is also a special top assembly available to convert the S-1 to a circulation type "Q" system. A special jacket design to ASME pressure vessel code is available. Normal pressure rating of jacket is 10 PSIG. Please see the list below of all accessories available. 10 S-1 SERIES ACCESSORIES 1. 1-1/2 Gallon Stainless Steel Tank with Stationary Arms 2.
