The mixing vessel is ." thick and the vessel heads are ¾" thick. The stub end bearing is 1-15/16" diameter. Materials of Construction: Interior of mixer and all product contact surfaces constructed of Type 304 Stainless Steel polished to #120 grit cross pad finish. Exterior stainless steel is polished to #80 grit cross pad finish. Exterior non-stainless steel is painted manufacturer's standard ivory. Drive: A 15 HP, Class I, Group D, Division 2, inverter duty motor, rated for 460 volt, 3 phase, 60 Hertz input power. Drive consists of a Falk 08UJ2A flange mounted speed reducer direct driven by main drive motor. Electrical Wiring: All electrical wiring is to terminate in a NEMA 7 terminal box mounted on mixer. Wear-Edged, Heat Transfer Mixing Tools: Wear-edged, heat transfer mixing tools are concentrically arranged on the mixer shaft with head scrapers welded onto the end plows. Plow arms are securely bolted to the 3½" diameter, solid 304 stainless steel main shaft within heavy duty plow pockets. Plow assemblies are easily removable, if so required. The leading edge of each mixing tool and head scraper is covered with an abrasion resistant coating. Access Door: One (1) hinged access-cleanout door (14" x 22") is located on front side of mixer. A NEMA 7 safety switch is mounted on door. Charging Port: One (1) 15½" diameter flanged charging port is located on top center of mixer. The charge port body is extended by 12" for installation of the 3" Tri-Clover port for the two- fluid nozzle assembly described below. Vent Port: An oversize 15½" diameter flanged vent port is mounted on top of mixer complete with vent extension and vent bag. The vent extension will have one (1) 3" Tri-Clover port for the two-fluid nozzle assembly described below. The vent bag is also oversized to allow for proper venting of the mixer. Vent Bag Shroud: A 304 stainless steel shroud located around vent bag and mounted to vent extension with a 3” NPT connection to customer’s in-house dust collection system. Discharge: A 15½" diameter flanged port located on bottom of mixer complete with gasketed contour door, pneumatically operated. Seals: Air purge seals installed on main and chopper shafts. An air manifold complete with valves, gauges, flow meters and regulators is included. The drive end seal is 3" diameter, the stub end seal is 2" diameter. Chopper System: Two (2) high speed, coupled chopper assemblies, each powered by a 10 HP, Class I, Group D, Division 2 motor, rated for 460 volts, 3 phase, 60 Hertz input power. The chopper shafts are 1." diameter and the chopper blade assembly is Littleford’s special patented 4-point flat blade with carbide tips. Liquid Injection System: Two (2) tower mounted liquid injectors, for liquid addition. The extended charge port body and vent extension will each have one (1) 3" Tri-Clover port with a two fluid, air atomizing nozzle installed in it. Liquid Injection System: Two (2) lance type liquid injectors, one (1) installed on the front falling side on each chopper shaft centerline, for liquid addition. Liquid Injection Ports: Two (2) liquid injection ports with contour plugs, one (1) installed below each chopper assembly, for future addition of liquid injection lances. Jacket: A fully stayed, 90 PSIG @ 330ºF, ASME code constructed, 304 Stainless Steel jacket of labyrinth design to insure uniform flow. Thermocouple Port: One (1) thermocouple port with thermowell is mounted on back side of mixer for customer's temperature indicator. Manuals: Service, Maintenance, and Parts Manuals - two (2) copies. PRICE FOR U.S. BUILT UNIT...................................................................$118,520.00 OPTIONAL EQUIPMENT OPTION A Jacket Insulation: A 2" thick foamglass insulation installed around 90 PSIG jacket, covered with an aluminum sheathing, riveted and caulked in place. PLEASE ADD...................................................................................$2,255.00 OPTION B Mixer Base: A fabricated carbon steel supporting base providing up to 36" height from floor to discharge port. Base is to be painted manufacturer’s standard ivory. FOR U.S. BUILT, PLEASE ADD...................................................................$5,380.00 OPTION D Pulse Back Filter: A 10 square foot pulse back filter constructed of 304 stainless steel product contact surfaces is equipped with a removable top head plate and fully stayed, 90 PSIG @ 330ºF, ASME code constructed, 304 stainless steel jacket. The filter bags are mounted over stainless steel cages and can be easily removed through the top of the unit. A pneumatic pulse jet system provides cycled automatic bag cleaning without causing process interruption. This provides a smooth operating dust control system. The filter housing will have two (2) couplings, one (1) on the dirty air side and one (1) on the clean air side for a customer supplied pressure differential gauge. This is in lieu of the 15½" diameter vent extension, vent bag and vent bag shroud quoted. FOR U.S. BUILT, PLEASE ADD.....................................................................$27,010.00 OPTION G Jacket Insulation: A 2" thick foamglass insulation installed around 90 PSIG jacket of Pulse Back Filter, covered with an aluminum sheathing, riveted and caulked in place. PLEASE ADD......................................................................................$1,155.00 OPTION H Thermocouple Port: One (1) thermocouple port with thermowell is mounted on back side of mixer for customer's temperature indicator. PLEASE ADD........................................................................................$425.00 OPTION J Discharge Indication: Provide open/closed position indicating switches to the discharge valve. The two switches will be wired into the NEMA 7 terminal box and includes intrinsically safe barriers.
