plant is capable of processing 300 tph and it requires an average of five days to relocate the plant Because the plant is normally working eight hour shifts at 300 tph the lost production for each move is 12000 tons If that material is worth 7 per ton the lost revenue is 84000 per move or 840000 per year The solution Identify methods to reduce the amount of time between moves to capture some of the lost production thereby reducing the cost per ton and the amount of waste In my friends case he was able to eliminate 16 hours of downtime per move or 160 hours per year just by upgrading his plants to be equipped with hydraulic stabilizers to jettison the cribbing process This reduced his indirect labor costs by 32000 per year while adding 48000 tons of production He also eliminated the need to rent a crane for each move which saved him an additional 20000 per year in rental costs My friend reduced his total annual relocation costs from 340000 to 288000 while increasing his annual production total to 552000 tons The arithmetic shows that he reduced his transportation costs from 68 cents to 52 cents per ton which is more than a 23 percent reduction He also increased his annual revenues by 336000 Most importantly he is providing a safer working environment for his crew by eliminating the cribbing timbers the slings and the chains PORTABLE PLANTS A KPI JCI and Astec Mobile Screens Kodiak Plus K500 portable crushing plant is loaded and ready to move While it might not be realistic to eliminate waste completely from your operation there will always be opportunities for small incremental improvements that can add to the bottom line All that is required is a desire to find and remove the barnacles P Q Paul Smith is a product development manager at KPI JCI and Astec Mobile Screens He can be reached at paulsmith@ kpijci com Italvibras Industrial Electric and Mechanical Vibrators Engineering that delivers innovation with performance and reliability Since 1959 LA R G EST I N V E N T O R Y DI R E CT T O Y O U 3 Y E A R W A R R A N T Y Italvibras USA 1940 Vans Way Princeton IL 61356 phone 815 872 1350 fax 866 337 2693 www italvibrasusa com www pitandquarry com January 2014 PIT QUARRY 61
