The results show that under the pressure gradient of 750 Pa/m in the developed part the predicted material flow rate is 10 t/h and the measurement material flow rate 8 t/h.

And the questions, that may exist in each tache,which must be paid attention to, are introduced in this paper, including material transportation system, batching plant system, raw material grinding and waste gas disposal system, raw material homogenizing and feeding into rotary kiln system, firing end.

According to the manufacturer s technology and experiences for solid material transportation devices,it is pointed out that the safety protection methods and how to realize in the material transportation devices.
