Mining operations require very particular solutions for their unusual situations. RoboVent has decades of experience designing and manufacturing dust collectors to fit this kind of need. For example, RoboVent's Mobile series of dust collectors are built to move. No mining operation stands still, and neither can its air management equipment.
The recent increase in the cases of silicosis amongst Australian workers has seen silica being dubbed "the new asbestos". Silica exposure is an emerging issue in Australia and knowing how to protect yourself is fundamental to worker safety across a broad range of industries.
Introduction. Silica is the name given to a group of minerals composed of silicon and oxygen, the two most abundant elements in the earth's crust. Silica is found commonly in the crystalline state and rarely in an amorphous state. It is composed of one atom of silicon and two atoms of oxygen resulting in the chemical formula SiO2.
