Crucible Tumbler
GLS’s crucible tumbler is a new type of forward and reverse rotating mixing equipment. The crucible tumbler is mainly used for batch mixing of fire assay mineral samples and fluxes. The device can mix up to 50 fire assay crucibles at a time. This significantly improves the efficiency of laboratory sample preparation and reduces manual operations. It is one of the necessary equipment for fire assay laboratory.
The lengthy time required for fire assaying of gold, silver and precious metals can often be compensated for by the simultaneous analysis of a large number of samples. A typical fire assay laboratory is usually equipped with several furnaces and cupellation furnaces, each capable of collecting multiple samples. Therefore, GLS’s Multiple Sample Load Forklift, Crucible Tumbler and other equipment have greatly improved the efficiency of laboratory sample preparation and load-and-unload.
