A NEW PERSPECTIVE ON REDUCING ENERGY CONSUMPTION IN GRANITE CUTTING WITH A MULTI-BLADE BLOCK CUTTER: THE CASE OF AN INDUSTRIAL

In recent years, the use of natural stone, especially in construction sector, has increased as a result rapid economic development. One most important cost parameters stone cutting processes is energy costs. Generally, cut granites with block cutters differ from other rocks terms both machines used and consumed. Increases prices emission reduction requirements require to work efficiently. This article describes consumption process processing plant, makes recommendations decision-makers for more efficient energy. A total 456 real tests were conducted at three different depths feed rates using multi-blade cutter 10 saw blades plant monthly production capacity over 4000 square meters. Real time values recorded help power analyzer installed on control panel cutter. The obtained data calculate specific values, consumed throughout entire was analyzed. blade moves back forth examined eight regions, starting first phase which approaches granite block. From calculated an approach been introduced efficiency characteristics rock circular blade.
