Is chromite sand dangerous?

IS CHROMITE SAND/FLOUR DANGEROUS?

Chromite sand is an ore composed of a mixture of iron, chromium oxide, silicate and other components,with Cr2O3 as main chemical and high strength,high temperature resistance and corrosion resistance;And chromite flour is produced from the raw material chromite sand through milling,mainly used in foundry,chemical,glass fields.

Although chromite sand/flour is a useful ore,but it also has some danger as follows:

1.Volatility:chromite sand/flour releases chrominum compounds at high temperature.

2.Toxicity:there is chrominum in chromite sand/flour,and chrominum is toxic metal.if touch long time,will be harmful to human.

3.Corrosivity:chromite sand/flour will corrode some metal and nonmetal.

Then how to use chromite sand/flour properly to avoid above dangers:

1.Protective measures:take protective golves,glasses etc to avoid touch skin and eyes.

2.Processing conditions:control the temperature and keep air circulation to avoid chromium volatilization.

3.Waste disposal:take action on protecting the environment when dealing with waste of chromite sand/flour.

In a word,chromite sand/flour is a useful material,but also a litte dangerous.As long as we take correct pretective measures,comply with relevant regulations and standards,it can be used safely.

PS:Sizes of chromite sand we produce:AFS25-30 AFS30-35 AFS35-40 AFS40-45 AFS40-50 AFS45-50 AFS45-55 etc

       Sizes of chromite flour:200mesh 325mesh 400mesh 600mesh 800mesh 1000mesh 1200mesh 1500mesh 2000mesh  2500mesh etc
