Stone crushers are small scale industries in the unorganised sector. They provide basic material for road and building construction. They are highly labour intensive. The various unit operations involved in stone crushing viz., size reduction, size classification and transfer operations have the potential to emit process and fugitive dust.

Regular maintenance is key to ensuring optimal performance and noise reduction in jaw crushers. Worn-out parts, such as bearings and belts, can lead to excessive noise. Hence, regular inspections and timely replacements help maintain a quieter and more efficient operation. This practice can also improve the lifespan of the crusher, resulting in ...

The paper examines the source of dust emission due to stone crushing activities and focuses on some selected woody tree species within the stone crusher plant. In the present investigation, sampling was done in four sites, east, west, north, and south of the stone crusher plant (SCP).

5 dust emissions however, improper design and operation of sprinklers and improper covering is an issue. Tertiary crushing: Fugitive emissions are generated during grinding of stones into fine dust. Conveyor Belt: Conveyor belts are primary means of transferring raw materials and products from one end to the other.

The study confirms that hauling and stone crushing of the mined material is chiefly responsible for generation of fine dust which may impose serious health effects …

Stone quarrying and crushing industries play a very significant role in the industrial and urban development programmes for the construction of roads, buildings, sheds and other similar activities. ... The control for dust emission includes wet dust suppression, dry collection and a combination of the two. The wet dust suppression is …

Abstract: The mining and stone crushing activities have considerable effects on the environment quality and human health. The dust emissions contaminate the air and water. Investigations made on ...

A variety of material, equipment, and operating factors can influence emissions from crushing. These factors include (1) stone type, (2) feed size and distribution, (3) moisture content, (4) throughput rate, (5) crusher type, (6) size reduction ratio, and (7) fines content. Insufficient data are available to present a matrix of rock crushing ...

The CPCB guidelines cover various aspects of stone crushing, such as source emissions, product storage, transportation, water consumption and legal compliance. Some of the key features of the guidelines are: The stone crushers should obtain consent to establish and consent to operate (CTO) from the State Pollution Control Board (SPCB) before ...

Personal dust sampling (n=11) and (n=6) was carried out in stone crushing and stone mining (quarry)areas respectively over a period of three consecutive days in selected units in a suburban area ...

Similarly, a dust emission study from stone crushers carried out in Tamil Nadu had assessed suspended particulate matter concentration in the range of 509–1206 μg/m 3 within a distance range of 380 to 90 m (Sivacoumar et al., 2007). Whereas, the coal crushers in general, ...

Dust is smallest matter of crushed aggregate which present in the open atmosphere. Due to the physical and chemical properties of dust particles, they cause adverse impacts upon the environment, atmosphere, human being and overall surrounding ... Dust Emission Due to Stone Crushers in Pune.

The tests were. divided into two target criteria sets: stone moisture levels greater than 1.5%. (wet), and stone moisture levels less than 1.5% (dry). However the stone. moisture levels were consistently lower than this criteria see Section 3, Table 3-l. The results of the PM10 emission tests are presented in Table l-l.

In May 2023, a study by researchers from Pune University revealed that a model stone crusher unit in Pune had successfully implemented pollution control measures and reduced its dust emissions by 90%. The study suggested that such units could serve as examples for other stone crushers in India.

One. Improve the process layout of the bag filter and arrange the filter of the crusher according to the direction of the belt conveyor. The standard dust hopper of the bag filter is changed into a double dust hopper structure. We cancel one screw conveyor and raise the bag dust collector, which is beneficial to the arrangement of air inlet ...

Dust emissions from the stone crushers should not be given low weightage as it is not less harmful than hazardous air pollutants. Many research studies conducted in India prove that stone crushers are not only a source of total suspended particles (TSP) and fine particulate matter (PM) 10, but also ultrafine PM2.5.

All processes of aggregate production are potential sources of dust emission.
