Abstract [en]

This study seeks to explore the different factors that affect bulk storage of quarried stone and associated products in the day to day operation of a profitable business.Swedish stone producers must have accurate knowledge of available products throughout the year in order to provide customers appropriate requirements at the time of need. One difficulty in carrying stock piles of bulk stone products is allowing for variants, such as wind wastage, and water absorbing which have a direct effect on the tonnage available. Customers who order in bulk need to know the dry weight cost in order to get the correct value of material, and in the case of concrete suppliers, for instance, controlled mixing of their final product. Where volume purchases are the norm, the transport required must know the weight/volume to be safe and legal.The overall requirements then for a successful stone quarrying business are varied; in order to provide a service the range of products must fulfil the needs of customers, be able to control or understand the variations that affect their products as mentioned previously, the impact on density of particle size/density, H2O content, flakiness index and screening curve. Also the variations that take place when paper calculations differ from physical checks on stockpiles.In order to remain profitable and, successful, control of these factors will enable any stone quarrying enterprise to go forward successfully.The result shown by regression indicates a connection between densities of particle size/density and the grain density of minerals.
