| Show important improvement and economy in the manufacture of flour A recent english paper contains a detailed account of ef a remarkable invention which is likely to effect a complete revolution in the manufacture of flour the improvement pro consists in the substitution of conical for flat millstones it was stated by a committee of df the house of parliament that by this invention kates in addition to those which are now made maae from the same quantity of wheat would be p produced ro d uce d RIV giving i ing a clear saving ol 01 of upwards of 00 per year the conical is intended to obviate the th defects of the flat mill the beneficial cial changes effected may be succinctly enumerated first the reduction of the weight of the run running i n g stone from 14 cwt cat to li 1 cwt cat by p placing I 1 Z n g it beneath instead of upon the fixed one second the reduction redaction of 8 34 to 1 and thirdly giving jiving to the stones a new form forin that of t the e faustrum fru strum of a cone the advantage of lesseur lessening ng the diameter and weight of a moo masaoy of which the one is 4 feet and the other is 4 ewt will be apparent when it is 1 considered that its ita effective velocity is I 1 revolutions per minute and that this velocity must be sustained nod against the enormous friction of the grinding surfaces sees the altered position of the running stone admits of a much more delicate adjustment n t of the 0 opposing apo surfaces and given ives ta the miller an ta 5 aas easy y and effective con control 0 0 over ver the most important important portion of Ms his operations the pon con mi form facilitates the di discharge of the flour and obviates the clogging croggin g and aad overheating of the old practice in addition to these advant advantages advantage ag es by moie a judicious i tion of the ordinary mode of d dressing reli r or rather by a combination of tho the mill wi with t the I 1 dressing machine a perret perfect separation of the flour floor from the bran is effected at the moment the grist escapes from the theartres theatres atres the bran still remains in the mill and fols falls by y its own gravity to a second ilir of stones in in all r respect beis those already ades described bribed cin in nonpareil Nonpar eu I 1 |
