RICHI Machinery has used a 4 t/h-class shrimp-feed raw-material grinding demonstration as the technical focus of customer discussions during an aquaculture industry exhibition.
Instead of presenting a booth built only around complete feed-plant capacity figures, the discussion starts with one of the most demanding parts of small aquatic feed production: obtaining sufficiently controlled ingredient fineness before mixing and forming.
The exhibition setting brings together customers at different purchasing stages. Some are planning complete aquafeed plants; others already own mixers, extruders and dryers and are looking for one new grinding section.
What Visitors Asked
“Can this replace our coarse hammer mill?”
Not necessarily.
For many shrimp-feed routes, coarse grinding and ultrafine grinding perform different jobs. Large ingredients should normally be reduced to an appropriate condition before entering the finer grinding system.
“Is the capacity always 4 t/h?”
No.
The demonstration is positioned around a 4 t/h-class preparation requirement, but practical output depends on ingredient characteristics, incoming particle size and required fineness.
A tighter target generally changes throughput and energy demand.
“Can we install only the grinding section?”
Yes, where the existing factory interfaces and downstream equipment are suitable.
A retrofit can include feeding, fine/ultrafine grinding, air classification or separation as applicable, collection, dust control and transfer to an existing batching system.
“Does every fish feed need ultrafine grinding?”
No.
Grinding requirements depend on species, feed size, formulation and production process. Shrimp and very small aquatic feeds typically justify closer attention to fine particle preparation than many larger livestock-feed pellets.
Why the Exhibition Story Is About a Module, Not a Complete Line
The commercial value of the demonstration is that it addresses buyers who may never search for a “turnkey feed mill.”
They may search instead for a shrimp feed ultrafine grinder, aquafeed micro pulverizer, fine grinding module for an existing fish feed plant, or small aquatic feed raw-material preparation system.
RICHI‘s exhibition team is using those discussions to separate customers who need a standalone grinding upgrade from those whose capacity, formulation or plant plan justifies a complete aquafeed production system.
Technical follow-up after the exhibition will be based on each customer’s ingredient samples, target feed size and existing equipment rather than one standard 4 t/h configuration.
