By the time the experiment 15 min large sand granules < resolution 38 of the sieve will be less, but if more time to grind is 30 and 45 minutes the result the weight of the sand grain size < 38 of the Sieve is increased. On the other hand, the 15 minute sand size 425-1000 has the most weight because of the grind a little time to make it so that the sand is sand size 425-1000 are the quantity and if added in to crush. The result is consistent. The weight of the sand there are 425 1000-size met values decreased.

In the experiment at 15 minutes of the sand size <38 from the sieve is less, but more grinding time was 30 and 45 minutes, the result was a weight of grain size <38 obtained. The Sieve will be increased. In turn, the size of a grain of sand for 15 minutes due to heavy grinding 425-1000 at least make the sand is not fine, so there is traffic, grain size 425-1000 if you add in the ground. The result is consistent Lynne 425-1000 weight of the sand is reduced.

The experiment 15 minutes time resolution of sand grain size < 38 obtained from sieve are smaller, but if more time to ground and 30 45. Minutes, the yield of grains of sand size < 38 obtained from Sieve increased.15 minutes sand size 425-1000 weighty due to grinding at less will do not have sand fine sand size 425-1000 in big quantity and if added vale in grinding. The result is consistent, the weight of the เม้ด sand size 425-1000.
