3.0–4.0 T/H Shrimp Feed Powder Grinding Mill in Ecuador

Why the Customer Chose a Single Ultrafine Grinder

In shrimp feed production, particle size consistency directly affects feed digestibility, sinking behavior, and nutrient absorption. For juvenile shrimp, coarse or uneven particles can reduce feeding efficiency and increase waste accumulation at pond bottoms.

The customer’s original hammer mill could only grind to around 60–80 mesh, and even then, the output was inconsistent. When producing shrimp starter feed, this caused several operational problems:

• Uneven powder texture after mixing
• Poor binding during micro-pellet forming
• Excess dust in the workshop
• Reduced water stability once feed entered the ponds

At first, the customer considered upgrading multiple machines. But after consulting with RICHI’s technical team, they realized that the bottleneck was not mixing or pelleting—it was grinding precision.

So instead of expanding blindly, they chose to add one Shrimp Feed Powder Grinding Mill as a second-stage pulverizer, keeping their existing equipment and improving performance where it mattered most.

This approach allowed them to control investment costs while immediately improving feed quality.

Local Raw Materials and Feed Formula Characteristics

Ecuador’s shrimp feed formulas differ slightly from those in Asia due to local ingredient availability and market preferences.

For this project, the customer mainly processes:

• Imported fish meal (high protein anchovy-based meal)
• Soybean meal
• Corn gluten meal
• Wheat bran
• Rice byproducts
• Calcium powder and vitamin-mineral premixes

These materials are typical for Ecuadorian shrimp feed, especially for nursery and early grow-out stages.

Fish meal and soybean meal contain relatively high oil content, making them prone to caking during grinding. Vitamin additives also require low-temperature processing to preserve activity. This is why the customer specifically needed a shrimp feed powder grinding mill capable of ultrafine grinding with controlled airflow and stable operating conditions.

After reviewing daily production volume and factory space, RICHI recommended the SWFL130 ultrafine crusher machine, configured as follows:

• Main motor power: 132 kW
• Classifier wheel power: 11 kW
• Feeding motor: 1.5 kW
• Grinding fineness: adjustable from 80 to 200 mesh
• Output capacity: approximately 3.0–4.0 T/H with pre-ground material under 2.0 mm

This model provided enough capacity for the customer’s current shrimp feed output while leaving room for moderate future growth.

How the Shrimp Feed Powder Grinding Mill Fits into Production

In this Ecuador project, the shrimp feed powder grinding mill operates as a secondary grinding unit.

Raw materials are first crushed using the existing hammer mill and screened to below 2.0 mm. This pre-ground material is then fed into the ultrafine grinder for precision milling.

After ultrafine grinding, the powder moves directly into the mixer, where oils and micro-additives are blended before forming shrimp feed powder or micro pellets.

The result is a much smoother feed texture, which improves:

• Pellet compactness
• Water stability
• Feed palatability
• Digestibility for juvenile shrimp

This single-machine upgrade enabled the customer to enter higher-value shrimp starter feed markets without rebuilding their factory.

Shipping from Qingdao to Guayaquil Port

Like all overseas projects, this Shrimp Feed Powder Grinding Mill in Ecuador was shipped by sea from Qingdao Port, China.

The destination port was Guayaquil, Ecuador’s primary commercial harbor and the main entry point for industrial equipment.

RICHI handled export packing, container loading supervision, and documentation preparation. The machine was shipped with electrical drawings, operation manuals, and spare wear parts, ensuring smooth installation upon arrival.

Why This Shrimp Feed Powder Grinding Mill Stood Out

Ultrafine grinding machines are used in many industries, but shrimp feed applications place particularly high demands on stability, fineness control, and wear resistance.

This shrimp feed powder grinding mill offers several technical advantages that directly benefit aquatic feed producers:

• Alloy-protected hammer heads reduce wear and extend service life
• Optimized liner layout increases cutting efficiency while minimizing circulation layers
• Wave-shaped alloy tooth rings improve shearing performance and material discharge
• High-precision dynamic balancing keeps vibration below 4 mm/s
• Automatic adjustable air damper allows accurate control of grinding fineness
• Built-in sensors monitor bearing temperature, vibration, and classifier speed in real time
• Hydraulic top-opening system simplifies maintenance
• Compact structure with integrated noise reduction saves valuable workshop space

Thanks to these features, the grinder handles oily fish meal and protein-rich materials smoothly while maintaining consistent powder size.

Beyond shrimp feed, the same machine can also be used for pet food powder, eel feed, crab feed, larval aquatic feed, and even certain chemical or pharmaceutical applications—making it a truly versatile ultrafine pulverizer.

What Changed After Installation

Even though the customer purchased only one shrimp feed powder grinding mill, the operational impact was immediate.

Powder uniformity improved dramatically. Mixing became more consistent, and micro-pellet forming required fewer adjustments. Dust levels dropped, and overall workshop cleanliness improved.

Most importantly, downstream shrimp farms reported better feed dispersion and reduced residue accumulation at pond bottoms.

Within weeks, the customer noticed a reduction in rejected batches and a smoother production rhythm.

Real Customer Feedback from Ecuador

After several months of operation, the customer shared their experience:

“Before installing this grinder, our feed powder was never truly consistent. Now the texture is much finer, and our shrimp clients noticed the difference right away. Maintenance is simpler than we expected, and RICHI’s engineers helped us adjust the classifier until we achieved exactly the fineness we needed. For us, adding this one machine solved many problems.”

They also mentioned that RICHI’s remote technical support was responsive, especially during the first production runs.

A Smart Step Toward Higher-Quality Shrimp Feed

This project shows that meaningful improvements don’t always require large-scale investments. Sometimes, adding one well-chosen ultrafine grinder can transform product quality and production efficiency.

With their shrimp feed powder grinding mill now fully integrated, the Ecuadorian customer plans to expand into nursery feed and specialty formulations for high-density ponds.

For producers searching for shrimp feed grinders, ultrafine pulverizers, aquatic feed grinding mills, or micro powder milling equipment, this case demonstrates how targeted upgrades can deliver fast returns.
