Shell is of a great variety, but its main component is more or less the same, full shell more than 95% is calcium carbonate, and a small amount of organic matters such as conchiolin, calcium carbonate in shell is vesicular structure, and its activity is higher than the calcium carbonate in Wingdale, and activation energy is low, a kind of Calcium Carbonate resource of high-quality, have can replace lime stone resource potentiality.But there is the following problem that replace lime stone is applied to cement clinker that affects in shell:
1. shell is hydrobiont, and the chlorion in shell, alkali content etc., apparently higher than Wingdale, may impact some application of its replace lime stone.
2. throw aside and have rotten organic matter above shell, can give out stink, environment is affected.
3. how in the form of sheets shell, has larger difference with the bulk morphologies that is of Wingdale more, as directly applied mechanically fragmentation and the processing mode of Wingdale, easily causes putty problem.
Therefore, find a kind of the problems referred to above that can solve in shell utilization, can utilize in enormous quantities shell rubbish, reach shell recycling, control the object of polluting, have technology and feasibility economically concurrently, be a problem demanding prompt solution simultaneously.
Utility model content
