The swarf crusher


Crushing of large swarf is a prerequisite for automatic swarf processing and cost-efficient transport.


SEVEN ADVANTAGES IN ONE MACHINE
  • High crushing performance with low energy requirement
     
  • Low noise crushing
     
  • Good accessibility of crushing chamber
     
  • Can be integrated in any swarf processing system
     
  • Long service life of low wear crusher tools
     
  • Low maintenance cost due to quick replacement of wearing parts
     
  • No special foundations required (B25 sufficient for dowel fixing)

HOW THE SWARF CRUSHER OPERATES

Long swarf is fed into the crusher hopper by swarf conveyor systems or other means. By an ultrasonic sensor at the crusher hopper the crusher is automatically switched on and off.

The long swarf in the crusher hopper is drawn by the tearing arm. Supported by guiding hooks it is first transported to the coarse crusher and then to the fine crusher. The broken short swarf is discharged by two wiper blades via a chute.

Small sized solid parts usually pass through the crusher without blocking. Larger parts and bar-ends which might block the crusher initiate the blocking control. A reversing sequence is automatically started to discharge the solid parts. If this is not possible after several clockwise and counter-clockwise rotations of the crusher head the crusher stops. The blocking material can then be removed through the inspection hatch. Due to the typically inclined position of the STEIMEL crushers there is hardly any spilling of swarf or coolant.

Option "E":
All crusher models can be supplied with an automatic solid part release system. In these crushers the front fine crusher chamber opens hydraulically. Usually the blocking parts are discharged together with the swarf through this opening when the crusher is in a slow reverse motion.

Optional equipment:
When using a hydraulically or pneumatically operated distributing guide the parts can be discharged separately.

After a preselected time the fine crushing chamber returns to its operating position.

OPTIONAL SOLID PART RELEASE SYSTEM OF THE SWARF CRUSHERS
The automatic solid part release system is designed to release solid parts out of the crusher if they block the swarf crusher. To this end part of the wall of the crushing chamber and crushing parts mounted to it are opened hydraulically by a guiding device. Thus a great clearance is created so that the solid parts can fall through. The crusher carries out several short starts with changing sense of rotation. Thus the solid parts can fall out of the crushing chamber together with some of the swarf in the crusher. Displacement is effected by a hydraulic cylinder which is controlled by an extra hydraulic system.

PRACTICAL EXAMPLE OF SWARF CRUSHERS
In an automatic lathe turnery tufted swarf is produced. To release them from adhering coolant we employed a de-oiling station consisting of the following parts
  1. Hoist an tipping device to feed the tufted swarf
     
  2. Swarf crusher RS300E for crushing swarf
     
  3. Scraper conveyor for conveying crushed swarf to the de-oiling centrifuge
     
  4. Continuous de-oiling centrifuge type PERMOLEX-POLAR
     
  5. Discharge of dried swarf by scraper conveyors to containers provided by customer
