Primary Crushing: The mined rock is crushed to the desired size using a primary crusher. The crusher reduces the size of the rock by breaking it into smaller pieces. Secondary Crushing: The crushed rock is then further reduced in size using a secondary crusher. This process helps to produce a more uniform size of crushed stone.
Silica can exist in water supplies in two main forms. The first of these is "Reactive Silica". Reactive silica is dissolved in water as the bisilicate ion making it a very weak acid. This type of silica can be removed by using specialized ion exchange resins since the silica is dissolved. However, these resins are difficult to regenerate.
Respirable crystalline silica dust generated during stone crushing operations has been linked to chronic lung disease and increased risk of tuberculosis. In India, most stone crushing mills operate without any dust control or containment systems. ... finding suggests that relatively inexpensive modifications that are available in the local ...

cases. A recent study in India of over a hundred stone crushing workers showed that 48% had TB alone or in combination with silicosis. In fact, TB is the most common cause of death in those with silicosis. Reducing worker exposure to respirable silica will lower the incidence of Silicosis, Cancer, TB and other disease among exposed populations ...
Silica exposed workers. Exposure to silica dust is a potent risk factor for TB, as demonstrated in multiple studies, notably among exposed miners and stone crushers.1–3 Silicosis, a lung …
Isolate and ventilate dust. The less silica dust you create or leave floating around in your vicinity, the less you are likely to inhale. Therefore, proper dust reduction and ventilation procedures are also straightforward ways of reducing silica exposure. If, for instance, your job involves cutting concrete blocks, the use of a wet saw (which dampens potential silica dust) …
Use vacuums with high-efficiency particulate air (HEPA) filters or use wet sweeping instead of dry sweeping. [iv] Additionally, workers should take the following personal hygiene practices into account to help protect …
Coal is often the main fuel source used to heat the cement kiln. Coal pulverizers are required to grind the coal from the bulk storage size to a smaller particle diameter to use in the kiln. Coal pulverizers significantly reduce the mean particle size of the coal, drastically increasing the fire/explosion hazard risk. Get Price

Silica dust can originate from various sources across different industries and work environments. Silica-containing products can emit dust particles during cutting, crushing, drilling, polishing, sawing, or grinding. Such …
Activities such as abrasive blasting with silica sand, sawing brick or concrete, sanding or drilling into concrete walls, grinding mortar, manufacturing brick, concrete blocks, stone countertops, or ceramic products, and cutting or crushing stone can result in worker exposures to respirable crystalline silica dust.
As silica dust is a significant risk factor for silicosis and tuberculosis (TB), this intervention could provide public health benefits to small-scale mining communities even in areas without ...
