This is a project regarding a fish feed powder making machine in Turkey. A fish feed extruder manufacturer in the Aegean region of Turkey, near the city of Izmir, was producing extruded feed for European seabass and seabream. Their existing hammer mill could only grind ingredients to 300-400 microns.
This is a project regarding a fish feed powder making machine in Turkey. A fish feed extruder manufacturer in the Aegean region of Turkey, near the city of Izmir, was producing extruded feed for European seabass and seabream.
Their existing hammer mill could only grind ingredients to 300-400 microns. When they tried to extrude this coarse flour, the pellets had poor water stability – they broke apart within 30-40 minutes. Seabass farmers were complaining.
The production manager (let's call him Mehmet) explained the challenge: "Extrusion requires a very fine, uniform flour. Coarse particles create weak points in the dough. When the pellet hits water, those weak points fail. The pellet disintegrates. We needed to grind our ingredients to 150-200 microns for proper dough conditioning and water stability."
The company produces about 18,000 tons annually of extruded feed for seabass and seabream – the two main aquaculture species in Turkey. Their customers are fish farms along the Aegean and Mediterranean coasts.
Mehmet looked for a fine grinding system that could achieve 150-200 microns consistently with fish meal, soybean meal, and wheat flour. He found the SWFL series ultrafine grinder from RICHI.
Name:
fish feed powder machine
Country:
Turkey
Date:
2025
Capacity:
2-3 tons/hour
Model:
SWFL110
Main Motor Power:
110kW
Raw Materials:
Fish meal, Soybean meal, Wheat flour
target particle size:
80-100 mesh
From the ultrafine grinder table, the SWFL110 (110kW) fish feed powder making machine was selected. Why this model?
Mehmet chose the SWFL110 because their hammer mill couldn't achieve the required fineness for extrusion. The ultrafine grinder was a new purchase – they kept the hammer mill for other products.
Turkey's aquaculture industry is sophisticated. Mehmet's mill uses:
The challenge is grinding the fish meal, soybean meal, and wheat flour to 150-200 microns. Fish meal is oily and tends to clog conventional grinders. Wheat flour is fine already, but the fish meal and soybean meal need significant size reduction.
The grinding process for extruded fish feed:
The final product is ultra-fine powder that creates a uniform dough during preconditioning and extrusion.
The SWFL110 fish feed powder making machine arrived at the Port of Izmir – Turkey's third-largest port, located on the Aegean coast.
Shipping time from Qingdao to Izmir is about 30-35 days. The machine was packed in a 40-foot container with:
Customs clearance in Izmir took about 5 days. Total landed cost was about 22% higher than the FOB price.
Installation took two weeks. Mehmet's team prepared a concrete foundation – the SWFL110 weighs about 5.5 tons. They poured a 200mm reinforced slab with vibration-damping mounts.
The electrical hookup required 380V, 50Hz three-phase (Turkish standard). The 110kW motor required a 250-amp breaker.
The air system required ducting to a dust collector. Fish meal dust is valuable, so Mehmet installed a high-efficiency baghouse to capture fines.
The first test run was with fish meal (pre-ground through 2.0mm screen). The classifier wheel was set to 2,700 RPM. A sieve test showed 94% passing through 80 mesh (180 microns). Perfect for extrusion.
After six months of operation, Mehmet documented the following results:
Before (feed hammer mill only – 300-400 microns):
After (SWFL110 ultrafine grinder – 150-180 microns):
Production output:
Quality improvements:
Here's what Mehmet said after six months (paraphrased from a conversation, translated from Turkish):
"The hammer mill couldn't get fine enough for extrusion. The flour was coarse. The dough was inconsistent. The pellets fell apart in water. Our customers were unhappy.
"The SWFL110 changed that. The classifier wheel gives us consistent 150-180 micron flour. The dough is uniform. The pellets are strong. They last 2+ hours in water. Our customers have stopped complaining.
"The classifier wheel is the key. The hammer mill had no control – everything came out regardless of size. The classifier wheel returns coarse particles for regrinding. Only fine particles exit.
"A few operational notes: The hammers wear – about 600-700 hours with fish meal (it's oily and abrasive). We bought upgraded alloy hammers – they last 800-900 hours. The classifier wheel needs cleaning weekly – fish meal oil builds up. We wipe it down with a solvent.
"Would I recommend this machine? Yes. For any fish feed extruder, ultra-fine grinding is essential for water stability. The SWFL110 delivers consistent particle size that improves extrusion efficiency and pellet quality."
Extruded fish feed has different requirements than pelleted feed. Here's why ultra-fine grinding is critical:
Mehmet's lab tested the relationship between particle size and water stability:
The SWFL110 fish feed powder making machine in Turkey achieves 150-180 microns consistently.
The SWFL110's classifier wheel is what makes it effective for extrusion. Here's how Mehmet uses it:
Mehmet's settings:
The result is consistent particle size across all ingredients, creating uniform dough.
The SWFL110 fish feed powder making machine in Turkey uses hammers with alloy protection at wear points. This is important for fish meal – it's both oily and abrasive. Oil can cause standard hammers to gum up. Abrasive bone particles wear them quickly.
Mehmet's hammer life:
The alloy protection extends life by 50%. Mehmet bought a spare set with the machine.
Fish meal oil builds up on the classifier wheel and grinding chamber. Mehmet's team cleans it weekly:
Weekly cleaning takes 45 minutes. It prevents oil buildup that would affect particle size.
The SWFL110 fish feed powder making machine shipped from Qingdao to Port of Izmir, Turkey – the country's third-largest port on the Aegean coast.
Shipping time from Qingdao to Izmir is about 30-35 days. The route goes through the South China Sea, past Singapore, across the Indian Ocean, through the Suez Canal, and across the Mediterranean.
The machine was packed in a 40-foot container. Customs clearance in Izmir took about 5 days. Total landed cost was about 22% higher than the FOB price.
The truck transport from Izmir to the mill was short – about 30km, roughly 45 minutes.
After six months of running the SWFL110 fish feed crusher machine, Mehmet shared several observations:
RICHI provided several services that helped Mehmet get the SWFL110 operational:
For an extruded fish feed manufacturer requiring water-stable pellets, the SWFL series ultrafine grinder is the standard.
Consider the SWFL110 if:
Consider a smaller model (SWFL90) if:
Consider a larger model (SWFL130) if:
For Mehmet's fish feed plant, the SWFL110 was the right investment. It improved water stability from 35 minutes to 2+ hours, increased extruder throughput by 28%, and paid for itself in 10 months.
If you're an extruded fish feed manufacturer struggling with water stability, look at your particle size. Coarse flour creates weak pellets that fall apart in water. Fine flour creates strong, durable pellets that last 2+ hours.
The SWFL110 fish feed powder making machine produces 150-180 micron flour – the ideal particle size for extrusion. The classifier wheel ensures consistency. The alloy hammers last longer with fish meal. The result is water-stable pellets that fish farmers trust.
For extruded fish feed, the math is simple: finer flour = better water stability = happier farmers = repeat business.
