Hammer mills can be used to process:

• cereal crops;
• oilseed meal and meal;
• biomass;
• sawdust;
• spices;
• feed ingredients;
• dry plant material;
• other loose or lumpy materials suitable for impact crushing.

The specific configuration is selected based on the moisture content, density, and size of the input material, as well as the desired output size and production capacity.

How It Works

The raw material is fed into the grinding zone, where a rotor equipped with hammers intensively breaks down the material. The final particle size is determined by the screening system, the rotor parameters, the type of hammers, the airflow, and the feed rate.

The pneumatic system performs two functions simultaneously:

• transports the ground product;
• removes heat from the grinding area.

This is especially important for raw materials that may lose quality if overheated or that require a consistent grinding process over an extended period of time.

Power and Performance

The line of industrial pneumatic hammer mills may include models with power ratings ranging from 15 to 45 kW.

Approximate capacity: 1,500 to 5,000 kg/hour, depending on the model, screens, raw material characteristics, and fraction requirements.

Available power options:

• 15 kW;
• 18.5 kW;
• 22 kW;
• 30 kW;
• 37 kW;
• 45 kW.

Actual throughput always depends on the specific raw material. Throughput may vary depending on changes in moisture content, material structure, feed size, or screen aperture diameter.

Faction Control

One of the main advantages of a hammer mill is the ability to adjust the final particle size to meet specific process requirements.

The result is influenced by:

• the size of the sieve openings;
• type and weight of the hammers;
• feed rate of raw materials;
• rotor configuration;
• airflow intensity;
• material properties.

The range of screen aperture sizes can be approximately 0.5 to 20 mm, which allows the equipment to be adapted for various grinding tasks.

Performance Materials

The mills can be manufactured from carbon steel or AISI 304 / AISI 316 stainless steel. The choice of material depends on the application, sanitary requirements, type of raw material, and operating conditions.

For food, pharmaceutical, or other manufacturing industries with strict hygiene requirements, it is generally advisable to consider stainless steel construction. For technical, agricultural, or bioenergy raw materials, carbon steel construction may be sufficient.

Wear Resistance and Industrial Reliability

The equipment is designed for long-term operation in industrial environments. To reduce wear, reinforced components, protective housing plates, wear-resistant hammers, and special surface treatments for the rotor and fan may be used.

This is important when working with abrasive or difficult-to-process materials, where conventional grinders quickly lose their effectiveness.

Equipment Specifications

Depending on the project, the kit may include:

• pneumatic hammer mill;
• raw material collector;
• pneumatic conveying system;
• cyclone or discharge unit;
• hoses for feeding and transporting;
• metal and stone trap;
• control cabinet;
• replaceable screens;
• Additional components for integration into the production line.

The configuration is determined on a case-by-case basis after analyzing the raw materials, the required production capacity, and the equipment installation conditions.

What to Consider When Choosing a Configuration

To ensure that the mill operates consistently at the desired settings, it is important to select not only the motor power but also the entire line configuration. Requirements for screens, hammer types, pneumatic conveying, dust extraction, unloading, and automation may vary depending on the material.

When choosing a configuration, keep the following in mind:

• type of raw material;
• moisture content and density of the material;
• inlet particle size;
• the desired fraction at the outlet;
• planned productivity;
• material specifications;
• method of loading and unloading;
• the need for suction;
• integration with existing production equipment.
