Investigation of the Performance of Chain Saws Used in Marble Quarries

In this study, the cutting performance of the chain saw machines used for block production in marble quarries was investigated. For this purpose, firstly, the specifications of the chain saw machines used in the four different quarries, type, and sequence of cutting tools are examined. In each quarry, the areal cutting rates were measured by changing the parameters such as arm pressure and chain speed during the cuttting. Cutting depth of cutting tool sequence is calculated according to parameters such as machine cutting speed, chain speed, length of cutting tool sequence and angle of cutting arm. In order to investigate the effect of cutting parameters on cutting performance, sieve analyzes were carried out by taking dust samples from each cut pile and grain size indexes were determined. In addition, some physical and mechanical properties of natural stones were determined in the laboratory. As a result of this study, optimum working parameters are proposed for the efficient operation of chain sawing machines used in 4 different quarries
