Background: Stone quarrying activities generate dust and fine particulate matters of silica and heavy metals. The prolonged exposure to suspended particulates leads to fatal respiratory complications.Silica sand, also known as silica or quartz sand, is a refractory particle with quartz as the main mineral component and a particle size of 0.020mm-3.350mm. According to the different mining and processing methods, it is divided into artificial silica sand and natural silica sand such as washed sand, scrub sand, and selected (flotation) sand.Silica Sand Processing Plant ZENITH Crusher

Feasibility Study of Stone-Dust as an Alternative Material to Silica

Stone-dust is an industrial waste produced during the crushing of different sizes of stone in stone crusher plants. Primarily, stone-dust contains SiO 2, Al 2 O 3, and Fe 2 O 3, and some impurities.Around 15–20% of stone-dust is generated during the stone crushing processes. 26 Stone crushing plants generate around 59.4 megatons of stone The concrete has been developed by making use of binary and ternary concrete mixes by the use of silica fume and stone dust. The binary and ternary mixes have been prepared by the inclusion of varying percentages of stone dust and silica fume by partially replacing fine aggregates with stone dust by 10%, 20%, 30% & 40% and after Development of sustainable concrete using silica fume and stone

Assessment of Occupational Dust and Silica Exposure in Indian Stone

Exposure to dust and crystalline silica in stone quarry and crusher sector can lead to deterioration of pulmonary function 20,21. Magne et al (2003) in his study has reported that exposure to crystalline silica in the range from 0.05 mg/m 3-0.1 mg/m 3 for a period ranging from 20Initial analysis has shown that in the stone industry, most silica overexposures have historically occurred in the crushed limestone commodity. The occupations most at risk include truck drivers, crusher operators, front-end loader operators, and rotary drill operators. On average, 20 to 25% of the samples from these occupations exceed the PEL.SILICA DUST SOURCES IN UNDERGROUND

A reduction in respirable particulate mass following the application of a fine mist of water in the Khurda District of Orissa demonstrated that relatively inexpensive modifications that are available in the local market can be effective at reducing silica exposures. Abstract Respirable crystalline silica dust generated during stone crushing Due to rapid urbanization and onset of various infrastructure projects, construction and demolition waste management is a key challenge to related stakeholders. The utilization of stone crusher dust (SCD) and silica dust (SD) generated as wastes in stone processing units is also a matter of concern as it leads to air pollution.
