Show ECONOMY OF FEEDING STAMPS WITH ONE FOURTH INCH ORE few mill men realize the importance of feeding stamps with fine material of course there is a limit to this for if it is too fine the stamps will clog and practically do d nothing however there is a happy medium and it is to that we wish to tall call attention the stamp is not a crusher but a ve reri rizer zery and therefore should not be called upon to do crusher work the preliminary crushing can be done in a jaw and toggle crusher at one fifth the cost of any other machine it is therefore economy to feed a good sized battery been with fine ore it has difficult to get a fine crusher for this purpose many dodge crushers have been used to accomplish these results but not altogether satisfactorily as this machine is only able to reduce a trifle finer than the ordinary coarse breaker so there is hardly enough difference to pay for the increased cost and mill men have hesitated to install them roll jaw crushers have met with much better success than any other type as it is the only crusher capable of doing really fine work its jaws may be set at one fourth inch and deliver a fine and even product actual size of product unscreened screened your finishers whether stamps rolls or mills with the finest ore that can be produced by these crushers by installing an intermediate crusher between the coarse breaker and stamps at a small expense the capacity of your mill will be increased to a large extent and the wear and tear lessened materially it is claimed that with 1000 pounds stamps a daily output of five tons per stamp is produced stamps at their best have small capacity and therefore a small crusher will supply which equals that of a blake dodge and set of roughing rolls combined unlike the so called fine crushers the jaws do not advance and recede but always remain the same distance apart the moving jaw rolls over the material which then drops out without clogging these crushers are not expensive and are in many places giving excellent satisfaction these remarkable machines are made by the sturtevant mill company of boston mass |
