1 The alkaline cementitious properties of calcining clay which contain kaolin e and quartz is studied.
2 Optimum calcining technology parameter from phosphogypsum to plaster of paris is determined.
3 In this paper, optimizing control of calcining heat and fuel combustion in a ring-type calciner are expounded.
4 The solid phase abrading and calcining at the proper temperature are necessary to this step.
5 The experiment results show that with calcining temperature rise the color of ferric red gradually deepened from mauve to chrysoidine , morphology of ferric red also changed.
6 Aiming at one of lithopone calcining rotary kiln process systems in some factory, this paper proposes a control method which is based on the equal mass and equal energy idea.
7 Red Lead Red lead is made by calcining litharge in a muffle furnace.
8 Taixi anthracite with high quality calcining is also suitable raw material.
9 In this paper the industrial conditions of calcining hydrate using recycle fluid bed calciner were introduced.
10 The process for the treatment of the waste acid from crude benzol refining with calcining process is studied,(www.Sentencedict.com) the optimum operation data are discussed and the process is optimized.
11 The carbonate from calcium carbonate, if not remoyed by calcining may cause foaming in the reactors.
12 The leaching solution was purified by ion exchange, and then ammonium metavanadate was precipitated. A qualified product V 2O 5 was obtained by calcining ammonium metavanadate .
