摘要/Abstract

摘要：

通过正交试验研究了石灰石粉冷态和热态气力输送的特性，确定了仓顶压力是对石灰石粉气力输送影响最大的因素，同时研究了闪速煅烧炉及旋风分离器温度对煅烧石灰石粉成品活性度的影响。研究发现，成品的活性度随旋风分离器温度的升高而显著提高。

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.
