CARE GARE NEEDED IN MAKING CEMENT Union Portland Cement Co Supplies Excellent Material Ia i t erial yv With a n wonderful natural store store- storehouse storehouse house of oC limestone Utah has be- be become become como be-como come a great treat producer of oC cement One de deposit In Weber eber canyon Is estimated to be practically ineX- ineX inex l for Cor It has been worked 1 constantly for Cor 20 years and the tho mountain ot of supply has been but barely scratched Tho The big ble nee need 1 of oC the tho Industry here In 11 It the tho mountain intermountain region Is market expansion and the de of a a constant constant demand At the present limo timo freight rates and shipping conditions are ure such that Utah southern Idaho tast east eastern ern Nevada Novada western Wyoming and anda ando a 11 small part of o Montana are ar served sen-ed with Utah cement URGE J CAPACITY C The Union Portland Cement company's plant Is located at Devils Devil's Slide about 30 miles east cast of oC Og Ogden In Weber canyon About 20 years ago aco Amon Moore of oC Colorado and his associates began the development of oC the limo lima deposits de- de deposits de posits there thero on a n large scale Now the tho plant has a o dally capacity of barrels of cement and a capacity of over barrels When operating full Cull time the tho plant furnishes employment for lor men an and 1 has a payroll of up- up upwards upwards up upwards wards of 1000 1 per month Conversion of the raw material Into cement forms an interesting process At Devils Devil's Slide Slid the dr dry pro pro- process process pro process cess Is used First the tho rock Is quarried on the tho mountaInside This Is done with small email coyote roote holes drilled 1 Into the rock 50 feet deep and then dug due laterally 50 60 foot foe on each each side making a holes holes T T These holes are arc loaded with dynamite an and 1 the explosion brings down hundreds of tons which the tho steam shovels load In small cars The cars transport the material to the tho crusher L C PROCESS Huge Huce gyratory crushers of oC man man- mano manganese steel r reduce duce the th rock until un- un until un until til It Is nearly pulverized It Js Is then sent to the storage bins From these it is taken through a drier house where the pulverizIng pulverizing ine Ing process s is continued at the same sarno time timo that the moisture Is removed This Is done in tube mills where the tho ho material Is ground to great treat ness fineness by steel balls ranging In size from five lIvo Inches to one and one half Inches In dia- dia diameter dia diameter meter There Thero ire are six crushers of this type In one of which there are of these steel balls weighing 21 pounds apiece Ground to the consistency teny of the finest flour the cement pow pow- powder powder der tier enters the tho huge kilns four four In number an and 1 after atter raveling ra down an Incline for lor feet through Increasing heat comes out in the form of clinkers wh h haro aro aro taken to the storage bins to coot cool oft of The Tho kilns are aro heated with pow pow- powdered powdered powdered dered coal which is blown Into the tho furnaces shooting a flame 40 feet long lone through the kiln creat creat- creating creating In ing a temperature of as high as noo 1100 degrees decrees Fahrenheit Fahre The Th fire firebrick firebrick brick composing the tho kiln are con con- continually con con- continually continually being replaced duo to the intense heat When the th cement has reached the bins of tho the finishing house two per cent of gypsum cypsum from southern Utah Is added The prod product Is then ready for the sacking machines TIC AUTOMATIC SACKERS S In this operation an Interesting ono one automatic sackers aro are used The Tho lacks sacks aro tied before beCore they th yare are even filled VII Valve I e sacks Backs are used and after they are ar filled tho ho little patented flap seals seals tho aper aper- aperture aperture ture lure where the tho cement was poured In Good cement Is secured 1 only through the th good mixing of the Ingredients so the chemist Is kept busy testing the tho materials The rock from the quarry contains on the average per cent cat cal calcium cal calcium oxide or lime limo and 2072 silica and some aluminum However those proportions vary so It Is necessary to keep test test- testIng test Inc lag Ing constantly One hundredth of the tho rock Is tested 1 as aj It pas passes es through the tho crusher house and after that tho iho samples sample are taken taleen T That Th t the tho product Is of superior quality Is shown by the stability of the th cement made mad structures sues as the th Utah state capitol building that have ha been ma made ol 01 o material from Crom this plant O V U P LI E The Tho Union Portland Cement company works are located a short short distance from the main line IIno of the tha Pacific railroad and anda II a switch twitch track leads directly to the company's buildings Enormous quantities of coal are brought In from Grass GraM Valley Valle UtAh to supply the tho furnaces over these the tracks track and the tha finished 1 ce- ce cement ce cement ment
