Valorization of Powder Obtained from Marble Sludge Waste

Stone industry has generated about 200 million tons of marble waste by marble processing industries whether in the form of sludge or solid blocks. The accumulated marble wastes contaminate water and air and have harmful effects on human health, plants, and animals. This study focuses on exploring the uses of powder obtained by drying and At 100% combined replacement rate of sand with marble waste and scoria there is a significant reduction of a slump by 60% (30 mm) due to the significant increment of water demand at the full replacement of sand with marble waste and scoria This argument also revealed by Moreover, to easily understand the difference, the result is Partial replacement of sand with marble waste and scoria for

The fractal evolution of particle fragmentation under different

The fragments with the diameter < 0.074 mm cannot be fragmented in any crushing machine [36]. Thus, the minimum diameter of fragments, d min,equals to 0.074 mm. Generally, as the initial diameter of particles is much larger than the minimum diameter of fragments d min,the percent finer by weight of fragments is simplified as (10) P d = d The marble under investigation (Tuscany, Italy) is made up of calcite grains whose sizes range from 0.1 to 0.3 mm.

Experimental study on the secondary breakup properties

The crushing of 5–10-mm coal particles and the formation of 1–3-mm fine particles were used to illustrate the aforementioned stage characteristics. Under an axial stress of 0–3 MPa, the mass fraction of the coal particles 5–10-mm in diameter decreased by 9.74% with a smaller reduction.In order to reduce wear and increase crushing efficiency of the 6-DOF (degree of freedom) robotic crusher, the maximum single-particle compression ratio function of the granular material and the wear model of the mantle liner under eccentric compression are established.
