Size reduction and deagglomeration

Nibblers are used as part of many processes, often directly integrated into the product stream. Main process uses are:

Deagglomeration after drying, spraying and mixing etc.
After storage in silos.
Below big bag stations, tipping stations, sacks, drums and containers where compaction may occur.
Before secondary processing including micronizing, milling, grinding and feeding.
Before pneumatic or mechanical conveying.
Reprocessing/reclaiming of oversize or off-spec materials.
After band driers.

Consistent particle size and high throughput with lower heat generation than traditional grinding solutions
Very short downtime with easy to clean design features giving full access from both sides with an optional extractable drive
Features allowing quick inspection and changing of the main screen
Minimum product temperature rise and fines generation due to low rotational speed and by use of a cutting action rather than creating excess heat by grinding
Easy adjustment of paddle / cutting screen clearance for maximum process flexibility
Metal to metal contact detection for maximum process safety (standard with ATEX version)
EHEDG design conformity, wash-out and wash-in-place seals
ATEX versions for gas and dust environments (also combined)
Highly efficient, low power consumption and low noise emission levels
