Abstract
1478972 Jaw crushers PEGSON Ltd 19 Aug 1974 [18 Aug 1973] 39161/73 Heading B2A Crushing apparatus comprises first and second crushing surfaces defining a crushing chamber, the first surface being moved towards and away from the second surface at a relatively low frequency (below 8Hz) and the second surface being vibrated at a relatively high frequency (above 8 Hz and preferably above 16 Hz). The second surface vibrates in a direction perpendicular to the plane of the second surface. As described, the swing jaw 2 of a jaw crusher is driven by an hydraulic motor 24 and cooperates with a "fixed" jaw 4. The jaw 4 is suspended by a flexible strip 62 and vibrated by a hammer 66. Two matched contra-rotating shafts 68, 70 are each provided with an out of balance block 76 and are driven by separate hydraulic motors 72, 74. The shafts are supported in a support member 78 receiving sprung rods 82. The member 78 moves the hammer to vibrate jaw at a frequency determined by the speed of the motors 72, 74. Alternative embodiments eccentric shaft and single toggle, or pitman and double toggle swing jaw drive. Vibration may be effected by a pulsed hydraulic system.
