The equipment can be used for:

• grinding solid food products;
• processing of dried and frozen raw materials;
• grinding spices, grains, and ice;
• preparation of chemical raw materials;
• work with polymer or powder materials;
• shredding of biological materials;
• processing of biomass and organic waste;
• preparing raw materials for the next stages of production.

The specific model and configuration are selected based on the type of material, its hardness, moisture content, feed size, and the desired output size.

How It Works

The raw material is fed through the feed opening into the working chamber. Inside, a rotor equipped with blade or tooth elements operates, intensively breaking down the material to the desired size.

The output particle size is controlled by the rotor type, blade configuration, operating speed, and the characteristics of the raw material itself. This allows the equipment to be adapted to various processing tasks without having to completely replace the production system.

Power and Performance

Rotary knife shredders can be equipped with motors of various power ratings—ranging from compact 2.2-kW models to higher-capacity 7.5–11-kW models.

Approximate specifications:

• power—2.2 kW or more;
• rotor speed—about 1,000 rpm;
• capacity—500 kg/hour or more, depending on the raw materials;
• loading – bulk;
• entrance opening—approximately 300 × 300 mm;
• Design: a mobile structure on wheels with a locking mechanism;
• The working parts are made of AISI 304 or AISI 316 stainless steel, depending on the project requirements.

Actual performance depends on the material, the size of the feed material, hardness, moisture content, and the desired grinding result.

What to Consider When Choosing a Model

To select the right rotary knife grinder, it is important to evaluate not only the motor power but also the characteristics of the material itself. The same shredder may exhibit different performance levels when processing dry food ingredients, frozen products, polymer materials, biomass, or organic waste.

When choosing a model, you should consider the following:

• type of raw material;
• the hardness and density of the material;
• humidity;
• size of the pieces at the inlet;
• the desired fraction at the outlet;
• sanitary performance requirements;
• the need for automatic startup;
• the ability to integrate into a production line.

Terms of Manufacture and Delivery

The production time for the equipment is 3–5 weeks after receipt of the prepayment.

Terms of delivery: FCA, manufacturer’s warehouse.

Payment Terms:

• 70% – prepayment;
• 30% — before shipment.

The warranty on the equipment is 12 months.

To select a crusher model suited to a specific material and production load, contact UGN Invent Club for consultation. We will determine the raw material specifications, the required particle size, and the required throughput, and recommend the optimal configuration.

Advantages of Stainless Steel Construction

AISI 304/316 stainless steel provides corrosion resistance, easier cleaning, and compliance with stricter sanitary requirements. This is particularly important for manufacturing facilities where equipment comes into contact with food, chemical, or biological raw materials.

This implementation allows you to:

• reduce the risk of product contamination;
• simplify sanitation procedures;
• work with more challenging materials;
• extend the service life of the equipment;
• adapt the shredder to meet European manufacturing standards.

Key Benefits for Manufacturing

A rotary knife grinder is a compact yet high-performance solution for businesses that need to quickly prepare raw materials for further processing.

Advantages of the equipment:

• high performance for its class;
• uniform grinding of the material;
• adjusting the particle size distribution by changing the rotor and blade types;
• stainless steel construction;
• compact design;
• the ability to move within the production area;
• easy loading of raw materials;
• the ability to integrate into a production line;
• selecting a configuration for a specific material;
• Equipment overload protection, depending on the configuration.

Where the equipment can be used

Rotary knife shredders can be useful in various manufacturing sectors.
