ENVIRONMENTAL ISSUES IN STONE CRUSHERS | The …

 · 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 dust may be emitted.
