The particle size of limestone powder for desulfurization is 250 mesh or 325 mesh (45 μ m), and the desulfurization effect of 325 mesh limestone powder is better. To prepare such fine limestone powder, the mill mainly adopts Raymond mill, pendulum mill, ball mill or European mill. In the past, Raymond mills and ball mills were used more.

The first-order rates are commonly observed in batch grinding (Austin et al., 1984) and are the basis of modeling breakage in tumbling mills.In the case of particles contained in coarser size ranges, deviations from linearity are identified in Fig. 1, as have been observed by other investigators (Austin et al., 1982).This behavior, in which grinding rates appear to slow down with time, has

Aid, agglomerates of fine particles are rejected and pass the ball mill again. Repeated impact and attrition cause a certain pro-portion of very fine particles and a broad particle distribution. Expressed as inclination of the particle size distribution according RRSB, cements from ball mills generally have a rather low slope [n’].

The effects of ball diameter and revolution speed on the mean particle size (d 50) of the limestone ground at different time intervals are shown in Fig. 1. For all ball sizes employed here, d 50 decreased for the first 30 min of grinding and remained almost invariable for grinding periods longer than 60 min.

Having selected the best ball size, it will be seen by referring to tables 27 and 28 that the preferable ball size usually gave the best capacity and efficiency. Also, the preferable ball size coincides closely with the best selective grinding, the main exception being the “plus 10-mesh” series in table 28.

METHOD RESULT Graph 1 Mass fraction vs Particle size DISCUSSION T heoretically, in ball mill, if larger ball was used to grind the large sample, , it would break them quicker than small ball. But if small ball was used, the sample particle size would be finer. Sample of limestone would be more crushed using 100 rpm.
