Show PRODUCTION AND RELATED DATA Aggregate was belt-conveyed from the adjacent aggregate plant, bin stored, and dry batched through a C C standard 3 compartment Bin-a-batch. Batch was dumped into berser mixer, bagged cement was hand-added, and water metered in. Steam curing was employed throughout production period. Curing kilns with dimensions 42ft. long by 20 ft. wide by 7'-7" clear height having concrete block walls and precast concrete roof slabs were erected and serviced by Kewanee, 150 H.P. horizontal oil-fired boilers, Model HM-885, five (5) kilns and one boiler for each Besser machine, Kiln design capacity was 2,600 block each. A curing cycle of approximately 8 hours total was adopted. Two hours were required to bring loaded kiln to 100% saturated steam at 175° F. Steam remained on for an additional 3 hours, and cool-down required another 3 hours. A total of five (5) Erich son 3,500 lb. Fork lifts, model F-6R, were used to load and unload kilns. Mack 5-Ton tracks, two having mounted Superlite Block Unloaders, wore utilised for the bulk of plant to work area hauls. Average block truck load as follows: TYPE NO. BLOCK / LOAD 8 - 4 - 16 1,080 8 - 4 - 8 l,800 4 - 2 - 8 4,290. Plant personnel required, two machines operating, for each shift as follows: Operate mixer, batcher, and block machine off-loader, 6 men per machine 12 Fork lift operator 5 Truck Driver 2 Stripping line 15 boiler operator 2 Supervisor 1 TOTAL 37 |
