Hammer Mill | Feed Milling & Particle Size Control | Bellaex
Hammer mill for feed & grain: adjustable speed and quick-change screens deliver target particle size with low fines. Handles corn, wheat, soybean meal; integrates before mixing and pelleting.
OVERVIEW
WHO USES IT, WHAT IT DOES, AND WHY IT PAYS
SUMMARY
Material enters the water-drop chamber and is guided across slope-adjustable toothed plates for pre-grinding. The dynamically balanced, high-precision rotor drives consistent impact, while the reversible direction evens wear and extends service life. Optimized hammer layout and tight tolerances reduce vibration and noise. A patented one-step screen hold-down and full-size sliding access door simplify inspection and mesh changes; interlocks enhance operator safety. Adjustable hammer–screen clearance lets you tune for different raw materials and sieves.
APPLICATIONS & MATERIALS
Animal feed, Aqua feed, Pet food, Grain processing, Oil processing, Brewing. Materials include Corn, Wheat, Sorghum, Oats, Durum wheat, Paddy, Beans, and crushed cakes.
KEY FEATURES
- Water-drop grinding chamber + W-shaped second-pass structure increases effective grinding surface (capacity gain up to 25%).
- Dynamically balanced high-precision rotor; optimized hammer layout for low vibration & noise.
- Reversible rotation extends wear-part life and keeps particle size consistent.
- Slope-adjustable toothed plates boost pre-grind on hard cereals (corn, wheat).
- Patented one-step screen hold-down and full-open sliding door for fast, safe mesh changes.
- Interlock protection and wide access for friendly, CE-minded operation.
ADVANTAGES
Throughput & Efficiency
Enlarged chamber, secondary grinding path and toothed pre-grind plates deliver more tons per hour with lower recirculation.
Stability & Wear
Precision balancing, reversible rotor and high-hardness hammers reduce vibration and extend service intervals.
Operation & Safety
One-step screen clamping, big sliding door and door interlocks make maintenance faster and safer.
Process Fit
Adjustable hammer–screen gap and sieve options cover pre- and post-grinding across species diets.
Materials & Finish
Heavy-duty welded housing; stainless contact parts optional for corrosive applications

MODELS
132×36
132×36 (Small lines): 6–12 t/h wheat / 8–13 t/h corn; ideal for specialty or starter lines.
132×65
132×65 (Mainstream): 14–28 t/h wheat / 18–34 t/h corn; the most common choice for mid- to high-throughput feeds.
132×102
132×102 (Centralized): 25–32 t/h wheat / 32–40 t/h corn; suited to high-capacity pre-grind before batching.
FAQ
How do I size the hammer mill?
Start from required t/h at the intended sieve size and moisture. Use our table to shortlist a width, then match motor power to your raw materials and aspiration volume.
What sieve size should I pick?
Choose by downstream process (e.g., pelleting). Smaller sieves increase energy and reduce capacity; larger sieves raise throughput with coarser PSD.
How do I minimize wear and vibration?
Run correct tip speed, keep rotor dynamically balanced, reverse rotation periodically, and maintain the hammer–screen gap per material.
Is screen change fast and safe?
Yes. The one-step hold-down mechanism and full-open sliding door with interlock enable quick, tool-light changes and safer access.
Can it handle hard-to-grind materials?
Yes. Slope-adjustable toothed plates pre-condition hard cereals (corn, wheat) to raise efficiency; select proper hammers and sieve alloy for abrasive loads.
