Spice Grinding Cone Mill, Doebritz Industrial Mills, Stainless Steel / ATEX Certified

Product Summary

Engineered for the most demanding spice processing lines, the Doebritz Spice Grinding Cone Mill delivers superior particle size reduction from 0.5mm to 5mm with throughput capacities up to 2,500 kg/h. Featuring a fully stainless steel 316L contact part, ATEX certified explosion-proof design (Zone 22), and minimal dust emission (<0.5mg/m³). This mill is specifically designed for fragile spices such as black pepper, coriander, cinnamon, nutmeg, and dried herbs, ensuring low heat generation and exceptional product uniformity.

Why Source Doebritz Spice Grinding Cone Mill

• Precision CNC Machining: Rotor-stator gap tolerance within ±0.1mm ensures consistent particle size and minimal air leakage (≤0.5Nm³/h at 100mbar).
• ATEX Zone 22 Certified: Complete certified explosion-proof motor and grounding system, eliminating spark risks during high-speed grinding.
• Rapid Changeover Design: Tool-less screen and rotor replacement reduces downtime by 70% for multi-product spice lines.
• CIP/SIP Ready: Fully washable design with FDA-compliant seals for sanitary spice processing.
• Global OEM Supply: 15-year track record supplying leading spice multinationals. 24/7 technical support and spare parts availability within 48 hours.

Housing & Rotor Engineering

The Doebritz Spice Grinding Cone Mill features a one-piece cast 316L stainless steel housing with a seamless internal finish (Ra ≤ 0.8µm) to eliminate bacterial growth and material retention. The proprietary serrated cone rotor with 3D-optimized blade geometry creates a powerful vortex action that gently mills spices without thermal degradation. Outboard bearing assembly isolates the drive mechanism from the product zone, while double mechanical seals with nitrogen purge capability ensure zero contamination. The quick-release clamp ring allows full access to the milling chamber in under 30 seconds.

Frequently Asked Questions

What is the minimum order quantity (MOQ) for the Doebritz Spice Grinding Cone Mill?

Our standard MOQ is 1 unit for stock models. For customized mills (special rotor coatings, non-standard flanges, or explosion-proof variants), MOQ is 1 as well with a lead time of 4-6 weeks.

Can you customize flange drilling to ANSI or DIN standards?

Absolutely. We support all international standards: ANSI B16.5, DIN 2633, JIS, and BS. Provide your flange drawing for 100% non-standard customization at no extra engineering fee for first-time OEM orders.

Is the mill ATEX certified for Zone 20 (dust) environments?

Yes, the Doebritz Spice Grinding Cone Mill is available with full ATEX certification for Zone 20, 21, and 22. Certification documents (EC-Type Examination Certificate) are provided with each ATEX unit.

What is the maximum operating temperature for high-heat spice milling?

Standard version operates up to 80°C continuous. For hot spices or processes requiring up to 150°C, specify the HT (High Temperature) configuration with upgraded seals and bearing lubrication.

What’s your typical lead time for a 2,000 kg/h capacity mill?

Standard units ship within 20 working days. Custom-engineered orders with special rotor designs or coatings: 35-45 days. Expedited 15-day shipping available for emergency replacement units.
