Optimization of grain composition in the system of packing particle

The grain composition in the system of packing particles plays an important role in production of many products. It has great influence not only on the final quality but also on the technological quality of products. In this paper ,the optimization model of grain composition is presented first on the background of how to select the reasonable grain composition for producing the unshaped refractory in a factory and to combine the conditions of the factory with the theory of packing in compression and craft requests. Then the rationality of model is proved and the solving arithmetic is designed according to the real conditions and property of the model. The results of computation show that the model and the arithmetic are feasible for optimization of grain composition of packing particles in general.
