speed of a roll crusher

The single-roll crusher has a tip speed of400-450 ft/minwhile the6- x 7-ftteethed roll crusher has a normal, no-load, surfaces speed of just under3500 ft/min. It can be readily appreciated that this high velocity induces an extremely violent crushing action, in conjunction with the 3- to 4-in.

The springs are helical and pressure varies with the size of crusher and could be as high as6t/m (about8300 kPa). In some roll crushers the rolls are individually driven. The drive is either by gears or belt. Both rolls usually rotate at the same speed but some crushers are designed such that one roll could rotate faster than the other.

Triple Roll Crusherscombine a SingleRoll Crusherwith aDouble Roll Crusherto form a crusher that is capable of achieving a 6:1 reduction ratio in the primary stage and a 4:1 reduction in the secondary stage while producing a cubicle product at high capacity.

A drive arrangement for aroll crusherincludes two rollers arranged in parallel, two trains, each for driving a roller. The two drive trains each has a gear transmission including a drive shaft which can connect to a motor and an output shaft which can connect with a roller. Each gear transmission includes an intermediate shaft arranged between the drive shaft and the output shaft.

Roll CrushersFor crushing a variety of soft to medium-hard products, Bauermeister'sRoll Crushersoffer high throughput with narrow particle size distribution. The creation of undesirable fine particles is reduced by subjecting the product to a combined shearing and pressing action.

The minimum product sizing of a SingleRoll Crusheris generally limited to2-3”. The crushing is carried out between the full width of the extra-long curved crushing plate and the low-speed crushing roll. The curvature of the crushing plate provides an ample throat opening to capture large irregular feed lumps.

Fourrolltypeteeth crusheris actually made up of two doubleroll teeth crushers.Teeth roll crusheris outstanding for its largecrushingcapacity. In addition, the hydraulic coupling with limited distance connecting the motor and reducer prevents overload and the overload protection sensor device makes the machine safe and reliable.

Jackshafts for control ofroller speedare standard on doubleroll crushers, optional on larger SingleRoll Crushers. Protective Spring Releases Heavy-duty compression springs permit movement offloating rollto pass tramp metal and other uncrushables, avoiding overload and damage.

Crushing and shearing play a critical roll in mix quality, so we use a twin-speed roller design. The slow roller turns at approximately 280 rpm and is paired with a fast roller running at approximately 290 rpm.
