Commercial Spice Hammer Mill for Dry Material Pulverizing

Product introduction of Spice Hammer Mill

Designed for demanding spice and dry ingredient processing, this industrial hammer mill pulverizer combines high-speed grinding, pneumatic conveying, cyclone separation, and dust collection in one continuous system. Raw material enters the grinding chamber, where rotating hammers repeatedly strike and shear it against the liner. Particles remain inside until they are small enough to pass through the selected screen, allowing operators to adjust finished powder fineness for different recipes and materials.

Airflow generated during operation transports ground powder from the mill to the cyclone separator, where the main product is collected and discharged through a rotary valve. Finer airborne particles are directed to the dust collection section for recovery. The system offers a capacity of 100–800 kg/h, 10–120 mesh output, 21.25 kW total power, and 2900 rpm operating speed. Stainless steel construction, convenient screen replacement, bearing protection, and optional chamber cooling support reliable operation, easier maintenance, and hygienic food powder production.

Key Features

Continuous Grinding and Discharge

The integrated grinding, conveying, separation, and collection system allows material to move continuously through the process, making it suitable for higher-volume spice powder production.

Replaceable Grinding Screen

Different screen openings can be selected according to the required powder specification, providing finished fineness from approximately 10 to 120 mesh.

High-Efficiency Hammer Grinding

High-speed rotating hammers create strong impact and shearing forces against the material and chamber liner, providing effective size reduction for dry and suitable fibrous ingredients.

Integrated Cyclone Separation

Ground material is pneumatically conveyed to the cyclone, where the main powder is separated from the airflow before being discharged through the rotary valve.

Pulse Dust Collection

Fine airborne particles are captured by the dust collection system, helping recover usable powder while reducing dust around the processing area.

Air-Assisted Material Flow

Negative-pressure airflow helps transport powder through the system and can reduce material accumulation around the screen during continuous grinding.

Convenient Screen Replacement

The screen structure is designed for straightforward removal and replacement, allowing operators to change particle size specifications with less downtime.

Protected Bearing System

A sealing structure helps prevent fine powder from entering critical bearing areas, supporting longer component life and more stable operation.

Technical Parameters

Actual capacity and finished fineness may vary according to raw material characteristics, moisture content, feed size, screen opening, and operating conditions.

How the Hammer Mill Pulverizer Works

Raw material is fed into the grinding chamber, where rapidly rotating hammers repeatedly impact the particles and throw them against the fixed liner. Impact, shearing, friction, and particle-to-particle collisions gradually reduce the material size.

Particles that are still too large remain inside the chamber for further grinding. Once they become smaller than the selected screen openings, they pass through the screen and enter the pneumatic conveying section.

The airflow then carries the powder toward the cyclone separator. Most finished product is separated and discharged through the rotary valve, while finer suspended particles continue to the dust collection system for recovery.

Spice Processing Applications

• Chili Powder Production
  Suitable for reducing dried chili into powder for seasoning, sauce, and food ingredient preparation.
• Pepper Grinding
  Processes suitable dried pepper materials into controlled powder sizes for commercial spice production.
• Dry Herb Pulverizing
  Can be used for selected dried herbs and plant materials requiring impact and shearing during size reduction.
• Seasoning Ingredient Processing
  Suitable for preparing dry seasoning components before blending, mixing, or packaging.
• Cumin and Coriander Grinding
  Provides continuous milling of suitable dried seeds and spice ingredients into smaller particles or powder.
• Food Ingredient Pulverizing
  Can process various compatible dry food materials where controlled particle reduction and continuous powder collection are required.

Suitable Raw Materials

The machine is particularly suitable for dry materials that can be efficiently reduced through impact and shearing, including:

chili, pepper, cumin, coriander, dried herb, seasoning ingredient, dried spice, grain and selected food material.

For materials containing high levels of oil, moisture, or sticky components, grinding tests are recommended before final equipment configuration.

Frequently Asked Questions

1. What materials can the hammer mill pulverizer process?

It is suitable for dry spices and food ingredients such as chili, pepper, cumin, coriander, dried herbs, and seasoning materials.

2. What is the processing capacity?

The machine provides a capacity of approximately 100–800 kg/h, depending on the material and required powder fineness.

3. What powder fineness can it achieve?

The finished powder size is approximately 10–120 mesh. Different screens can be selected for different grinding requirements.

4. How does the hammer mill grind spices?

High-speed rotating hammers create impact, shearing, and friction forces to reduce the raw material until it can pass through the selected screen.

5. Does the machine include a dust collection system?

Yes. The system combines cyclone separation and dust collection to recover fine powder and reduce airborne dust during production.

6. Can the grinding screen be replaced?

Yes. Replaceable screens allow operators to adjust the finished particle size according to different materials and production requirements.

7. Is it suitable for continuous production?

Yes. The integrated grinding, pneumatic conveying, cyclone separation, and rotary discharge system supports continuous powder processing.
