Abstract:

In this paper,the characteristics of cold and hot pneumatic conveying of limestone powder are studied by means of orthogonal experiment.It is determined that the pressure of the silo top is the most influential factor for pneumatic conveying of limestone powder.At the same time,the influence of the temperatures of flash calciner and cyclone separator on the activity of limestone powder calcined products are investigated.It is found that the activity of limestone powder calcined products significantly improved  with the increase of cyclone separator temperature.
