100 mesh granulated sugar pin mill grinding project in Mexico

• Material: Granulated sugar
• Requirement: 100 mesh
• Production Capacity: 300–450 kg/h

Mexico’s sugar industry provides a steady supply of granulated sugar for food, beverage, and pharmaceutical applications. Several downstream processes require a finer sugar powder with a controlled particle-size distribution around 100 mesh. To meet quality and consistency targets, a dedicated pin mill grinding solution was evaluated for its ability to produce uniform 100 mesh sugar at a stable production rate.

System concept

The project adopts a pin mill grinding configuration integrated with a classifier to achieve precise size reduction and narrow distribution. The flow begins with feeding granulated sugar into the pin mill, where high-speed pins generate impact and shear forces that fracture crystals. The ground material then enters a classifier section, where fine sugar exits, and coarse fractions are returned for regrind. Proper tuning of feed rate, pin configuration, and classifier speed yields a tight 100 mesh target with minimal over- or under-grinding.

Sugar Pin Mill Grinding Project Preliminary Testing

To better serve our customers, EPIC Powder Machinery conducts preliminary testing and verification for every project.

Key design parameters

• Pin mill configuration: double-row pins, high-speed rotor
• Classifier type: centrifugal or cyclone-based with adjustable rotor speed
• Feed moisture: < 1% to prevent agglomeration
• Airflow management: dedusting and product collection via a single-pass or closed-loop system

Operational performance targets

• Particle size distribution: peak around 100 mesh with 5–8% oversize
• Throughput: 300–450 kg/h depending on bulk density and moisture
• Power consumption: minimized via optimized grinding efficiency and classifier tuning
• Dust control: effective filtration to maintain workplace air quality

Estimated process flow

• Pre-drying or conditioning of sugar if moisture exceeds 1%
• Feeding into pin mill at controlled rates
• In-line classification and product discharge
• Optional post-milling stage for tighter distribution if required

Prototype data snapshot

• Target: 100 mesh (150 microns)
• Observed: 95–105 mesh distribution with less than 6% oversize
• Throughput: 320–420 kg/h under standard conditions
• Energy: Specific grinding energy within expected range for pin mill systems

Notes and considerations

Sugar crystallinity and moisture have a strong impact on grinding efficiency and lump formation; maintaining low moisture is essential.

Steel contact surfaces require corrosion resistance and hygiene compliance for food-grade applications.

Cleaning and sanitation procedures should be integrated to prevent cross-contamination in multi-product plants.

Conclusion

The 100 mesh granulated sugar pin mill grinding system offers a compact, efficient solution to produce uniformly distributed 100 mesh sugar at a production rate of 300–450 kg/h. The integrated grinding and classification approach enables tight particle-size control, low fines loss, and acceptable energy usage for a Mexican sugar-processing facility.
