differences bitween (CKD) cement kiln dust and (CBPD) cement bypass dust
My question is about the differences between cement kiln dust and cement by-pass dust. I understand that cement kiln dust (ckd) is a dust form cyclones and bag filters during the production of clinker and cement bypass dust (cbpd) is collecting in the bypass. But where should by bypass emplace? In the cold or hot end of kiln?

Re: differences bitween (CKD) cement kiln dust and (CBPD) cement bypass dust
Cement kiln dust is the dust which passes out of the top of the preheater with the exhaust gases, or more typically out of the back of a long wet or long dry kiln. Bypass dust is the dust that is drawn out of the kiln inlet when some kiln exit gases are extracted between the kiln and preheater to break the cycle of volatile species between the kiln and preheater. The bypass is therefore positioned between the kiln inlet and the preheater.
