Rotary Granulator
Rotary granulator with a rotating cutter that presses mixed material through a screen into neat granules, ideal for highly viscous materials.
Overview
The ZLB rotary granulator turns well-mixed material into the required granules and is especially suited to highly viscous materials. All parts in contact with the material are made of stainless steel.
Features
- Stainless-steel contact parts with a neat appearance and rational structure
- High granule-forming rate with good-looking granules
- Automatic discharge that avoids the granule breakage of manual discharge
- Well suited to in-line production
- Particle diameter of Φ0.5-6 mm, adjustable to the user's need
Working Principle
A rotating cutter presses the mixed material through a screen, forming granules of the set diameter. The granules are discharged automatically, protecting them from the breakage that manual discharge can cause.
