Mi 1itel 1o DATE: August 13, 1976 DESIGN MEMO NO. 1 Revision 0 Subject: Flowsheet, Equipment List and Cost Estimate 1.0 SCOPE This memo gives the preliminary flowsheet, equipment list and order of magnitude cost estimates concerning the proposed Supervisbestos circuit at the K>ng City plant. 2.0 DESIGN CRITERIA The wetted Supervisbestos circuit is based on the following: Production Rate - 4.0 dry tons/hour Maximum Moisture - 25% (wet basis)* 3.0 PROCESS DESCRIPTION The flowsheet is shown in Figure 1. Dry Supervisbestos is fed to a pug mill where it is mixed with water (to bring water content to 20-25%). The material is then transferred to a pellet mill where the material is extruded into pellets, the size of which is yet to be determined. Finally, the dustless material is bagged and sealed by sewing. 4.0 EQUIPMENT LIST See Table I 5.0 EQUIPMENT LOCATION A pug mill and pellet mill were tentatively located above the existing bagging line. The plant has not been able to find a location for the new bagging system which seals the bags by sewing. Thus, this preliminary study is not based on an intergrated layout. ' Preliminary - Additional tests required 1 UCC 011001 Design Memo No. 1 Revision 0 Subject: Flowsheet, Equipment List and Cost Estimate 6.0 COST ESTIMATE The cost estimate given in Table II was prepared by Mr. F.R. Angelori. The order of magnitude cost estimate for a Wetted Supervisbestos circuit is $255,000. 2 UCC 011002 PRELIMINARY WETTED SUPERVISBESTOS FLOWSHEET *NEW EQUIPMENT UCC 011003 H2O PRODUCT TABLE I EQUIPMENT LIST EQUIPMENT QUANTITY NOMINAL CAPACITY SIZE MTL CONSTR CONN HP UNIT TOTAL 1 H30 Mill* 2 M30 Mill* 3 Mix Tank* 4 Surge Tank* 5 Filter* 6 Drag Conveyors* 7 Extruder-Dryer* 8 Bucket Elevators* 9 Disc Mill* 10 Live Bottom Bin* 11 Feeder 12 Pug Mill 1 5 tph 18"x48" Steel 3/4 3/4 1 5 tph 6.3'x6.4'x4' Steel 20 20 13 Pellet Mill 14 Bagger 1 5 tph SteeT 25 25 7'x3.51 1 5 tph Steel 1/3 1/3 15 Closing Machine 16 Conveyor 1 5 tph 12"x251 Steel 1/3 1/3 3 5 tph Steel 1 3 17 Dust Collector* Existing equipment UCC 011004 TABLE II ORDER OF MAGNITUDE COST ESTIMATE WETTED SUPERVISBESTOS CIRCUIT (PROJECT COMPLETION 1977) Installed Equipment Equipment Installation Power wiring Piping Other Subtotal Installed Equipment $88,000 30,000 20,000 10,000 27,000 $175,000 Other Items Engineering & Construction Supervision Contingency Start-up Modifications 45,000 25,000 10,000 Subtotal Other Items $80,000 TOTAL CAPITAL COSTS $255,000 UCC 011005
