N -- GREEN SAND RECONDITIONING SYSTEM SOL F04699-95-R-0153 DUE 063095 POC For copy, contact the info office indicated., For additional information contact Melby.K8s/Pkocc/916-643-3795 The closing date of 31 May 95 is an approximation only. McClellan AFB is purchasing a green sand reconditioning system consisting of a sand cooler & heater, a green sand mixing system and a bond blending system. GREEN SAND COOLER: The green sand cooler shall back blend and homogenize 50 ton per hour (TPH) +/- 5 TPH of foundry shakeout sand on a continuous basis. Cooler to receive sand at temperatures ranging from 40 to 300 degrees F and 1.5% to 5.0% mean moisture. Cooled sand output from the cooler to be controlled to a range from 70 to 100 degrees F (to 3 sigma) and mean moisture to a range from 1.8% to 2.3% (to 3 sigma). Sand cooler to include an electrical heat source to dry excess moisture from the sand when required and an automatic lubrication system. The cooler will also measure the mass flow rate of the sand. The system shall have the provision for extracting fines, waste heat, and moisture when connected to a suitably designed, government provided dust collection system. The cooler shall have a motor control center to include motor starters and controls for the entire system. The cooler shall have a control panel and a programmable operator control station with touch pad input. The controls shall include an Allen Bradley Series 5 Programmable Controller to control all sand cooler functions, including production and diagnostic reporting as well as data output (Data Highway) to a government provided central plant computer. GREEN SAND MIXING SYSTEM: The green sand mixing system shall operate at 50 TPH and consist of a green sand muller, sand weight hopper, bond weigh feeder system, automatic bond determinator and programmable sand controller to control the entire mixing operation from charging through discharging to provide accurate control of sand moisture and compactability. The muller shall mix and mull a 5000 lb. batch of sand with a minimum energy input of 2.3 hp-hr per ton and shall include an automatic lubrication system. The green sand mixing system will receive sand in a range of 40 to 110 degrees F and with a mean moisture content of 1.5% to 2.5%. The green sand mixing system shall produce mulled sand with a mean temperature of 70 to 100 degrees F (to 3 sigma) with compactability in the range of 35 to 45% (+/- 3%), moisture content in the range of 3 to 5 percent (+/-0.1%), and green compression strength minimum 80 percent of remull green compression strength to 3 sigma. The system shall have the provision for extracting fines, waste heat, and moisture when connected to a suitably designed, government provided dust collection system. The green sand mixing system shall include motor starters and controls for the entire system. The green sand mixing system control panel shall include an Allen Bradley Series 5 Programmable Controller to control all sand mixing functions, including production and diagnostic reporting. The control panel shall also have a programmable operator control station with touch pad input and shall have data output (Data Highway) to a government provided central plant computer. BOND BLENDING SYSTEM: The bond blending system shall consist of a bag breaker, a mixer, pneumatic transporter and bond storage. The bond blending system shall thoroughly mix dry bagged or bulk green sand bonding materials and deliver them to the bond weight feeder system. The system shall be sized to deliver 0 to 4 percent of the green sand processing weight to a precision of 5 percent of the delivered amount. The system shall have the provision for fugitive dust collection when connected to a suitably designed, government provided dust collection system. The bond blending system shall have its own programmable operator control station with touch pad input. The system shall include motor starters and controls for the entire system. The system control panel (can be shared with the sand mixing system) shall include an Allen Bradley Series 5 Programmable Controller to control all blending functions, including production and diagnostic reporting and shall have data output (Data Highway) to a government provided central plant computer. 1 ea Applicable to: CERP Program Destination: McClellan Air Force Base CA 95652-1060 Estim Delivery: 31 Dec 95 1 ea Descriptions, quantities, locations are based on the best available data at the time.
