Sanmenxia Fused Alumina: Small Change, Big Achievement

Recently, Sanmenxia Fused Alumina Co., Ltd has adjusted quality control method to maximumly meet requirements of customer based on actual production and operation.

Lately, according to the quality demand of orders, Sanmenxia Fused Alumina Co., Ltd has allocated very few corundum blocks of the same level with different composition based on certain proportion. Through stirring and fully mixed, those corundum blocks will be processed again to satisfy customer’s quality requirements, and thus new costs of stirring are generated.

For the purpose of decreasing cost and increasing efficiency, Sanmenxia Fused Alumina Co.,Ltd has summarized experience and boldly attempted to change the former way of quality control. Firstly, Sanmenxia Fused Alumina has adopted more delicate classification for raw corundum block storage. Different levels of raw corundum blocks will be placed separately and marked effectively; secondly, Sanmenxia Fused Alumina Co., Ltd has changed to process suitable corundum block directly and separately based on clients’ demands. Only in some special cases will they choose different levels of raw materials to allocate and stirring. On the condition of satisfying clients’ requirements of quality, they have spared no effort to reduce the amount of stirring. After lots of trails, comparison, summaries and analyses, that method can not only meet quality demands of different customers, but also can reduce the costs produced by stirring.

At present, that quality control method has been implemented effectively in the production of corundum sand.
