Particle size of limestone powder for desulfurization | LZZG

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.

article is to review different techniques for analysing size and shape of micrometric particles such as limestone fillers. Particle size measurement has been studied by means of laser light scattering, wet sieving (45, 63 and 125µm) and static image analysis. This last technique enables also to characterize the shape of particles.

Particle-size distribution

The particle-size distribution (PSD) of a powder, or granular material, or particles dispersed in fluid, is a list of values or a mathematical function that defines the relative amount, typically by mass, of particles present according to size. Significant energy is usually required to disintegrate soil, etc. particles into the PSD that is then called a grain size distribution.

Particle Size Conversion Chart | Williams Patent Crusher

Mesh size refers to the number of openings in one inch of screen. For example, a 4-mesh screen means that there are four squares within one inch of the screen. As the mesh size increases, the particle size decreases to create a finer material. Mesh size is not a precise measurement of particle size, but it is a fair estimation.
