Abstract: Crushed stone dust is material obtained from aggregate crushing industries. Use of such stone dust materials creates lots of problems in environment and public due to excess storage and dust accumulation. Considering this aspect an experimental study was conducted on expansive soil by mixing it with locally available crushed stone dust.

crusher. Tertiary crushing is usually performed using cone crushers or other types of impactor crushers. Oversize material from the top deck of the sizing screen is fed to the tertiary crusher. The tertiary crusher output, which is typically about 0.50 to 2.5 centimeters (3/16th to 1 inch), is returned to the sizing screen.

Crushers, screens and dust-collection fans all contribute to high noise levels. Air-cooled lubrication systems are not only noisy, but often leak oil. Well-balanced, choke-fed crushers, dust-enclosed screens and dust collector fans with silencers can keep noise levels under control. Recirculating water can be used to cool crusher lubrication

The greater the reduction in size during subsequent crushing stages from primary, secondary to tertiary crushing, the higher the emissions. Primary jaw crushers produce more dust than comparable gyratory crushers because of the bellows effect of jaw and because gyratory crushers are usually choke-fed, thus minimising the open spaces from which
