Effect of Stone Crusher on Ambient Air Quality

crushed in stone crusher. Stone crusher creates lot of noise and it emits dust particles in environment. Because of more concentration of dust particles in environment (air), it creates pollution. This pollution creates diseases in human and animal''s life like asthma, skin diseases, eye irritation etc. and it effects on vegetation.
