Abstract
The present invention has improved sulphoaluminate cement producing process, especially to utilize calcined ardealite to replace natural gypsum in the cement product compounding step in sulfphaluminate cement producing process. The present invention provides one new way of producing high quality sulphoaluminate cement by using industrial waste as stuffing.
Description
Technical field
The invention belongs to and utilize industrial waste to produce the technological design of sulphur (iron) aluminate cement.
Background designs
Sulplo-aluminate and ferro-aluminate cement all do not have essential difference from formula constituent, complete processing to physical and chemical index.What of calcium sulphoaluminate or iron calcium aluminate content wherein just, and people's custom is called sulphur aluminic acid base cement or ferro-aluminate cement.Also do not have strict boundary at present performed standard, so often the two is lumped together from technical standpoint, we also often comprise ferro-aluminate cement at this said aluminosulfate cement.So sulphur (iron) aluminate cement just commonly used is represented the product that this class is similar.Sulphur (iron) aluminate cement since coming out with its excellence fast hard, expand, low alkali characteristic obtained using widely in many special industries and field.The plaster of paris because of application of expensive in its raw material, and make its price more expensive, manufacture craft is also difficult to be grasped, and mainly takes Wingdale, alumina, the plaster of paris to be made into raw material in its production technique, makes sulphur (iron) aluminate cement grog after pulverizing, grinding and calcining.With the grog is base-material, add an amount of plaster of paris or properties-correcting agent can grinding after mixing preparation become sulphur (iron) the aluminate cement product of fast gravity die, expanded polystyrene veneer, the low various series of alkali type, how can reduce production costs simultaneously obtaining excellent properties, be the problem that those skilled in that art paid close attention to always.
Summary of the invention
The object of the invention is to utilize industrial waste to finish last grinding modification proportioning operation in the cement manufacturing, strive for replacing or partly joining, do weighting agent with industrial residue and reduce the cost of sulphur (iron) aluminate cement and guarantee its quality and characteristic for the plaster of paris with the industrial waste baking ardealite.With problem maximum in the ardealite instead plaster of paris is the high-moisture that solves phosphogypsum, so before phosphogypsum is used, will through the calcination processing that being not less than 800 ℃, and then the resultant baking ardealite replaced the plaster of paris as the part substitute, allotment cement character behind grinding.The improvement of another one key is can adopt multiple industrial waste to do filler to add in the cement products proportioning.Wherein, can adopt raw material that flyash is arranged, calcine and unburnt coal gangue.Tailings, mine tailing that iron ore beneficiation is remaining, slag or without the blast-furnace slag slag of hardening, with various industrial wastes through pulverize, the standard fineness of being ground to all can be as filler.Wherein the mixture of one or two or more kinds all can add application according to the requirement to cement physics and chemistry thing feature, from zero to 30% sulphur (iron) aluminate cement to produce different labels.

Claims (3)
1, produces the technology of sulphur (iron) aluminate cement with industrial waste, comprise proportioning, pulverizing, the grinding of sulphur (iron) aluminate cement raw material, the calcining of grog, be that base-material adds and joins each procedure that the plaster of paris and compound grinding are modified as cement powders with the grog, it is characterized in that in the cement grinding operation, having added baking ardealite and industrial residue, concrete pulverizing cement proportioning following (weight percent):
Sulphur (iron) aluminate clinker 50~80%,
Baking ardealite 0~25%,
The plaster of paris 0~15%,
Industrial waste 5~30%,
2,, it is characterized in that said baking ardealite is to make the industrial waste of phosphoric acid through being not less than the resultant of 800 ℃ of calcining gained according to the technology of the said production sulphur of claim 1 (iron) aluminate cement.
3, according to the technology of the said production sulphur of claim 1 (iron) aluminate cement, it is characterized in that said waste residue is flyash or calcined and unburnt coal gangue, the also iron ore mine tailing and the CHARACTERISTICS OF TAILINGS SAND of when ore dressing, discharging, or slag reaches blast furnace quarrel, slag without hardening, and their one or two or more kinds through pulverize, mixture behind the grinding, sneak into grog more by weight percentage and stir and become cement products.
