Sandviks crushing and screening products have a number of dust prevention solutions in place to protect quarry workers and the environment.
Stricter limits to silica dust exposure in mines and quarries have now been introduced across many of Australias states and territories.
The Workplace Exposure Standard limit for silica dust has been reduced to 0.05 milligrams per cubic metre mgm from 1 mgm and 1.5 mgm from 2.5 mgm of respirable coal dust.
These revised limits aim to prevent health complications caused by crystalline silica which is found in materials including sand stone concrete and mortar.
These materials are commonly used to make brick and tile products but the dust particles can easily damage the lungs and result in health complications such as silicosis which could be fatal.
More than half a million Australians were exposed to silica in 2011 with 5758 of those workers expected to develop lung cancer later in life.
To ensure site equipment meets the revised standards Sandviks dust prevention solutions used by its crushing and screening products include dust suppression control collector and extraction system solutions.

Intakes for air should be in an area of clean air or the intake filtered. This picture shows the inside of a duct feeding air to the pressurised cabin. The quantity of air introduced into the cabin should be known and checked to ensure that the system is working properly. Note the build up of dust in the ducting.
Areas of spillage such as around bagging plants should be kept clean and vacuumed regularly. Never use a brush as it makes dust airborne.

Stone dust is also known as rock dust or quarry dust and some products just have the brand name. The stone dust is collected using a screen that keeps the larger pieces of crushed stone above the screen while allowing the rock dust to fall through. This process is the reason why stone dust is often called quarry screenings.
