Hammer crushers

Appointment

Designed for grinding grains, legumes, grain mixtures, granulated raw materials and other raw materials with similar physical and mechanical characteristics to particles of the required size.

Crushers are mainly used in the food and feed industry, both separately and as part of technological lines.

Characteristic

• Capacity from 4 t/h to 100 t/h depending on the type of raw material, recipe and required degree of crushing.
• Minimum operating costs per ton by combining high productivity and customer-specific production with low maintenance costs and low energy consumption.
• Heavy-duty industrial design with removable side screens that can be replaced during operation.
• Specially hardened hammers, each row mounted on a common shaft for quick replacement of worn hammers.
• Crushing chamber with built-in stone catcher.
• Reversible feed valve for rotation of the rotor in two directions for use of both working edges of the hammers.
• Large hinged doors for easy access to the crushing chamber.
• Built-in aspiration air intake with perforated cover.
• Hammer crushers can be equipped with the following options:
  • air purifying filter complete with level sensors, pneumatic hammers;
  • discharge hopper for hammer mill with inspection hatch, cover and flange with level indicators.

Technical data

Performance figures are indicative only for medium moisture products and for screen shells with Ø holes. 5 mm

The principle of operation

A hammer crusher is a type of crusher that uses the impact of hammers to crush material. The operating principle of a hammer crusher is as follows:

1. The material is loaded into the crusher chamber.
2. The chamber is closed with a lid.
3. Inside the chamber there are hammers that are mounted on a rotating shaft.
4. The shaft begins to rotate and the hammers begin to move around the chamber.
5. When moving, the hammers hit the material in the chamber and crush it.
6. The crushed material exits the chamber through an opening.
7. During operation, hammer crushers can be equipped with additional devices, such as a sieve, to separate large pieces of material from small ones.

Thus, a hammer crusher works by hitting hammers on the material and crushing it to the desired fraction.

The grinding process is carried out by striking the product with rapidly rotating working bodies at a speed of 90 m/s, this impact provides the most economical specific energy consumption compared to other types of crushers.

Advantages

High performance:

• Largest work surface;
• Large crushing plates at the top of the crushing chamber;
• Unique design with a staggered arrangement of hammers, allowing to increase the striking surface of the hammer;
• Compact feeder with frequency-controlled dosing roller to optimize the feed rate of different types of raw materials;
• High level of automation;
• Highest safety thanks to temperature monitoring and overfill sensors.

Energy efficiency:

• Low energy consumption (up to 7 kWh per ton);
• Energy efficient motors with direct connection to the crusher rotor.

Low maintenance costs:

• Minimal wear due to the use of uniquely designed crushing plates and durable hammers;
• Possibility of quick and safe replacement of hammers on all 4 sides;
• Excellent balance of the crusher rotor due to the strict compliance of the hammers with tolerances;
• Shock absorbers minimize the transmission of vibration to the building structure (both concrete and steel floors);
• Automatic cleaning of the built-in magnet;
• Durability and reliability of the design.

High quality feed:

• Excellent feed structure according to individual recipes;
• Filter built into the hopper under the crusher (less contamination);
• Crushing according to customer needs;
• Flexibility of production - the frequency converter allows you to adjust the structure.
