3-4T/H Animal Feed Micro Pulverizer in Netherlands

From the ultrafine grinder table, the SWFL130 (132kW) was selected. Why this model?

• Fine grinding: 80-200 mesh (75-180 microns) – perfect for weaner feed
• Capacity: 3.0-4.0 tons/hour – matches their 20-25 ton/day requirement
• Digestibility: Finer particles mean better nutrient absorption
• Health: Reduced post-weaning diarrhea
• Classifier wheel: Ensures consistent particle size

Pieter chose the SWFL130 because their existing hammer mill couldn't achieve the required fineness for weaner feed. The ultrafine grinder was a new purchase for their premium starter line.

What He's Processing – Dutch Piglet Feed Ingredients

The Netherlands has a sophisticated feed industry. Pieter's mill uses high-quality ingredients:

• Wheat (local – Gelderland grows wheat): 30-40% – energy source
• Barley (local): 20-25% – fiber and energy
• Soybean meal (imported through Rotterdam port): 15-20% – protein
• Whey powder (imported from dairy industry): 5-10% – palatability and digestibility
• Fish meal (imported): 3-5% – high-quality protein
• Vitamins and minerals (specialized piglet premix): 3-5%
• Organic acids (added post-grinding): 1-2% – gut health

The challenge is grinding the wheat, barley, and soybean meal to 150-200 microns. Wheat is hard and abrasive. Barley has a fibrous hull that requires more energy to grind. Soybean meal is oily and can clog conventional grinders.

The grinding process for weaner feed:

1. Pre-crushed material (through 2.0mm screen) enters the grinder
2. High-speed hammer rotor impacts particles
3. Classifier wheel separates fine particles from coarse
4. Coarse particles return for regrinding
5. Fine particles (150-200 microns) exit with airflow

The final product is ultra-fine powder that piglets can digest efficiently.

Installation – Precision Grinding

The SWFL130 arrived at the Port of Rotterdam – Europe's largest port, located about 100km from the mill.

Shipping time from Qingdao to Rotterdam is about 30-35 days. The machine was packed in a 40-foot container with:

• SWFL130 grinder main unit (132kW motor)
• Classifier wheel assembly (11kW)
• Feeder (1.5kW)
• Spare hammers and screens (upgraded alloy for abrasive grains)
• Cyclone and airlock discharge
• Installation manual and electrical diagram in Dutch

Customs clearance in Rotterdam took about 3 days. Total landed cost was about 20% higher than the FOB price.

Installation took two weeks. Pieter's team prepared a concrete foundation – the SWFL130 weighs about 7.5 tons. They poured a 250mm reinforced slab with vibration-damping mounts.

The electrical hookup required 400V, 50Hz three-phase (Dutch standard). The 132kW motor required a 300-amp breaker.

The air system required ducting to a dust collector. Pieter installed a high-efficiency baghouse filter – weaner feed ingredients are expensive, so capturing fines is economically important.

The first test run was with wheat (pre-ground through 2.0mm screen). The classifier wheel was set to 2,600 RPM. A sieve test showed 95% passing through 80 mesh (180 microns) and 88% passing through 100 mesh (150 microns). Perfect for weaner piglet feed.

Performance – Healthier Piglets, Better FCR

After six months of operation, Pieter documented the following results:

Before (hammer mill only – 300-400 microns):

• Particle size: 300-400 microns (45-55 mesh)
• Post-weaning diarrhea incidence: 25-30% of piglets
• Feed conversion ratio (FCR): 1.55-1.65
• Daily weight gain: 380-400g/day
• Medication costs: €2.50 per piglet (for diarrhea treatment)

After (SWFL130 ultrafine grinder – 150-180 microns):

• Particle size: 150-180 microns (80-100 mesh)
• Post-weaning diarrhea incidence: 12-15% (reduced by 50%)
• FCR: 1.45-1.50 (improved by 0.1-0.15 points)
• Daily weight gain: 420-440g/day (10% improvement)
• Medication costs: €1.20 per piglet (reduced by 50%)

Production output:

• Rated capacity: 3.0-4.0 tons/hour
• Actual output: 3.5 tons/hour average
• Daily output (8 hours): 28 tons – matches their requirement
• Annual production through fine grinder: 7,500 tons (weaner feed only)

Quality improvements:

• Digestibility: Increased from 78% to 86% (in vitro)
• Diarrhea reduction: 50% fewer cases
• Growth rate: 10% improvement
• Customer feedback: Farmers reported healthier litters

The animal feed micro pulverizer cost delivered approximately €78,000. Payback period was about 12 months based on improved FCR and reduced medication costs.

Customer Feedback – Pieter's Experience

Here's what Pieter said after six months (paraphrased from a conversation, translated from Dutch):

"We knew that particle size affects digestibility in piglets. But our hammer mill couldn't get fine enough. We were stuck at 300-400 microns. The piglets were scouring. Our farmers were unhappy.

"The SWFL130 changed that. The classifier wheel gives us consistent 150-180 micron particles. The digestibility improved. The diarrhea reduced by half. The piglets are growing faster.

"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 wheat and barley. We bought upgraded alloy hammers – they last longer. The pre-screen matters – we use 2.0mm for wheat and barley, 1.5mm for soybean meal. The air balance affects yield – we found our sweet spot at 3,200 m³/h.

"Would I recommend this machine? Yes. For any piglet feed manufacturer, ultra-fine grinding is essential for gut health. The SWFL130 delivers consistent particle size that improves digestibility and reduces diarrhea."

Why Ultra-Fine Grinding for Weaner Piglets

Weaner piglets have unique digestive physiology. Here's why ultra-fine grinding is critical:

• Stomach pH: Piglets have limited stomach acid production. Coarse particles require more acid to break down. Fine particles are more easily digested in the stomach, reducing the risk of undigested material reaching the hindgut.
• Enzyme access: Smaller particles have more surface area for digestive enzymes. Studies show that reducing particle size from 500 to 150 microns improves protein digestibility by 10-15%.
• Post-weaning diarrhea: Undigested carbohydrates and proteins ferment in the hindgut, producing toxins that cause diarrhea. Fine grinding reduces undigested material reaching the hindgut.
• Growth rate: Better digestibility means more nutrients absorbed. Piglets grow faster. Trials show that reducing particle size from 400 to 150 microns improves daily weight gain by 5-10%.

Pieter's trials with 500 piglets:

• 400-micron feed: 390g/day gain, 28% diarrhea incidence
• 200-micron feed: 420g/day gain, 18% diarrhea incidence
• 150-micron feed: 440g/day gain, 13% diarrhea incidence

The SWFL130 animal feed micro pulverizer in Netherlands achieves 150-180 microns consistently.

The Classifier Wheel – Key to Particle Size Control

The SWFL130's classifier wheel is what makes it effective for piglet feed. Here's how Pieter uses it:

1. Pre-crushed grains enter the grinding chamber
2. Hammers impact particles
3. Airflow carries particles toward the classifier wheel
4. The classifier wheel spins at 2,500-2,800 RPM
5. Fine particles (below cutoff) pass through
6. Coarse particles return for regrinding

Pieter's settings:

• Wheat: 2,600 RPM (150-180 micron target)
• Barley: 2,500 RPM (slightly larger due to hull fiber)
• Soybean meal: 2,800 RPM (finer, 120-150 microns)

The result is consistent particle size across different ingredients.

Alloy Hammers – Longer Life with Abrasive Grains

The SWFL130 animal feed micro pulverizer in Netherlands uses hammers with alloy protection at wear points. This is important for wheat and barley – both are abrasive.

Pieter's hammer life:

• Standard hammers with corn: 800-1,000 hours
• Standard hammers with wheat/barley: 500-600 hours
• Alloy-protected hammers with wheat/barley: 700-800 hours

The alloy protection extends life by 30-40%. Pieter bought a spare set of alloy hammers with the machine.

The Built-In Silencer – Quieter Operation

The SWFL130 animal feed micro pulverizer has a built-in silencer. In the Netherlands, feed mills are often located near residential areas. Noise complaints are a concern.

Pieter measured:

• Without silencer (competitor machine): 95-98 dB
• With built-in silencer (RICHI): 82-85 dB

The difference is significant for operator comfort and neighborhood relations.

Shipping – Qingdao to Rotterdam

The SWFL130 shipped from Qingdao to Port of Rotterdam, Netherlands – Europe's largest port.

Shipping time from Qingdao to Rotterdam 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 animal feed micro pulverizer was packed in a 40-foot container. Customs clearance in Rotterdam took about 3 days. Total landed cost was about 20% higher than the FOB price.

The truck transport from Rotterdam to Gelderland was about 100km – roughly 1.5 hours.

What Pieter Learned – Lessons for Other Pig Feed Manufacturers

After six months of running the SWFL130 animal feed micro pulverizer in Netherlands, Pieter shared several observations:

Lesson 1: Particle size directly affects piglet health. Don't guess – test. Pieter uses a sieve shaker every shift. The target is 95% passing 80 mesh (180 microns).

Lesson 2: Different ingredients need different classifier speeds. Wheat needs 2,600 RPM. Barley needs 2,500 RPM. Soybean meal needs 2,800 RPM. Document your settings.

Lesson 3: The pre-screen matters. For whole wheat and barley, use 2.0mm pre-screen. For soybean meal, use 1.5mm pre-screen (it's already partially ground).

Lesson 4: Alloy hammers are worth the investment. They last 30-40% longer with abrasive grains. The higher upfront cost pays off in reduced downtime.

Lesson 5: Monitor air balance. Too much air and you lose fines to the dust collector. Too little and the mill clogs. Pieter's sweet spot is 3,200 m³/h.

What RICHI Provided Beyond the Machine

RICHI provided several services that helped Pieter get the SWFL130 animal feed micro pulverizer operational:

• Dutch documentation: The manual and electrical diagram were provided in Dutch.
• Alloy hammer recommendation: Based on the abrasive wheat and barley, RICHI recommended upgraded alloy hammers. Pieter ordered them with the machine.
• Particle size guidance: RICHI provided recommendations for classifier wheel speeds for different ingredients.
• Air balance training: A RICHI technician spent 1 day on-site training Pieter's team on air balance and classifier adjustment.
• Spare parts kit: RICHI recommended a spare parts kit based on Pieter's volume – including hammers, screens, and classifier blades.

Is an Animal Feed Micro Pulverizer Right for Your Operation?

For a piglet feed manufacturer requiring ultra-fine particle size for digestibility and gut health, the SWFL series ultrafine grinder is the standard.

Consider the SWFL130 animal feed micro pulverizer if:

• Your target particle size is 150-200 microns (80-100 mesh)
• Your capacity requirement is 3-4 tons/hour
• You produce weaner starter feed for piglets
• Digestibility and health are key priorities

Consider a smaller model (SWFL110) if:

• Your capacity requirement is 2-3 tons/hour

Consider a larger model (SWFL150) if:

• Your capacity requirement is 4-5 tons/hour

For Pieter's piglet feed plant, the SWFL130 was the right investment. It reduced post-weaning diarrhea by 50%, improved FCR by 0.15 points, increased growth rate by 10%, and paid for itself in 12 months.

Final Thoughts

If you're a piglet feed manufacturer, don't underestimate the importance of particle size. Weaner piglets have immature digestive systems. Coarse particles cause post-weaning diarrhea – a major cause of mortality and medication costs.

The SWFL130 animal feed micro pulverizer produces 150-180 micron particles – the ideal size for weaner piglet digestibility. The classifier wheel ensures consistent size. The alloy hammers last longer with abrasive grains. The built-in silencer reduces noise.

For weaner piglet feed, the math is simple: finer particles = better digestibility = healthier piglets = lower medication costs = happier farmers.
