SARIISIK, A.  e  SARIISIK, G.. Efficiency analysis of armed-chained cutting machines in block production in travertine quarries. J. S. Afr. Inst. Min. Metall. [online]. 2010, vol.110, n.8, pp.473-480. ISSN 2411-9717.

This study analyses the results of a pilot trial of a newly developed armed-chained stone-cutting machine. The machine was developed in Turkey and trialled at the Kaklk/Kocaba travertine quarries in the Denizli District. An armed-chained cutting machine is an alternative to the diamond wire cutting method more frequently used in the production of natural stone quarry blocks, and increases production efficiency and quality. Since there is no need to collapse the blocks using the armedchained cutting production process, there is no risk of the block developing cracks. This results in a considerable increase in the efficiency of natural stone block production. The armed-chained cutting machine is easier both to assemble and run when compared to other block cutting methods. This process resulted in the production of a larger number of blocks at a lower cost within the same time frame, particularly in travertine quarries and in all other natural stone quarries. The block efficiency in travertine quarries was calculated as 65-80% using the armed-chained cutting machine, compared with 7-14% using the normal diamond wire cutting method.

Palavras-chave : Armed-chained cutting machines; travertine quarries; block production; diamond wire cutting; block efficiency.
