Abstract
The present paper presents a model that combines tools such as SLP (Systematic Layout Planning), 5´s, Standardization of methods and Preventive Maintenance for the reduction of waste in the manufacture of non-metallic minerals. This RMI (Industrial Rocks and Minerals) production sector has a high growth potential. Around 5 to 20 million tons were produced in the 70s, 80s and 90s, and it increased between 25 and 100 million tons annually in the present millennium in Peru. The problem to be attacked is the high amount of material that is wasted in the production process in small and medium-sized companies in the RMI production sector. With the validation carried out on our model, results of a reduction of material waste from 135.1 tons / year to 55.6 tons / year were obtained. This meant a waste reduction of 58.8%. The implementation of 5's until the standardization stage, indirectly impacted the other components. The result obtained with the layout redesign model was from 46.1 tons / year to 16.32 tons / year (65%), the redesign reduces the travel distances with material, which generates less waste in transport. In addition, a reduction of 35 tons / year to 10.5 tons / year (70%) is validated with the pilot testing of the definition and standardization of the prior rock breakage method. Also, the preventive maintenance pilot testing to the cyclone dust extractor, reduced the machine stops and validated than waste is reduced from 54 tons / year to 28.8 tons / year (46.7%).
