OVERVIEW

The Bauermeister 250.3 Roll Crusher is the most technologically advanced Roll Crusher especially suitable for the super abosrbent polymer industry. The 250.3 is second to none with high throughput and maximum control and flexibility.

Computer-controlled gap adjustment allows the most complete monitoring and control of all parameters. Welded steel modular design allows stacking individual pairs of rolls resulting in two-roll, four-roll and six-roll configurations.

The creation of undesirable fine particles is reduced by subjecting the product to a combined shearing and pressing action. The narrow particle size distribution is is achieved by controlling a combination of variables including roll speed, roll gap, differential speed, feed rate and roll surface design.

KEY FEATURES
• Product-contacted parts of stainless steel with especially
   smooth surface
• Inspection flaps for each pair of rolls arranged at the front and at
   the rear side of the machine as product chamber covers
• Dust-tight crushing chamber
• Direct drive by means of joint shaft and spur gear.

EQUIPMENT

• Electric switch cabinet
• PLC controlled
• Product feeding by dosing chute or roll feeder
• A spiration connection for de-dusting inside of crusher chamber
• Roll design in different material qualities, adapted to the
   product to be crushed:
    - Corrugated rolls with the various corrugation forms and sizes,
       depending on the specific product
    - Ring cut rolls with radial corrugations of different forms and sizes
    - Rolls with beaters
• Infinite roll gap adjustment by electic operation
• Automatic zero adjustment of the roll gap
• Considering temperature increase during the warm-up phase
• Consideration of wear-and-tear at the roll surfaces during
   zero adjustment
• Automatic roll gap opening during the starting phase

WORKING CHARACTERISTICS
• Continuous operation
• Narrow particle size spectrum of the final product with a minimum
   portion of dust

APPLICATIONS

Crushing of soft, brittle, to toughly-hard products.
