How a cutting mill works

A laboratory grinder is used to grind sample mixtures or materials of different consistencies. The function of a cutting mill is very simple, but highly effective. The principle of the cutting mill combines both the functionality of a shredder and that of a Laboratory mills shredder. With the aid of a so-called feed unit, you can feed the feed material in a self-dosing manner.

User convenience and flexibility of use

Depending on the task at hand, the feed of the respective substances can be individually adjusted. Usually, the material is shredded in advance so that it reaches the cutting mill area after passing through the shredder segment in the machine. There it is shredded to the previously set fineness. The vertical orientation of the cutting modules is important to ensure better accessibility to the cutting blade and the rotor.

The nature of the “inner workings

In this context, a vertical design is also advantageous in terms of cleaning the crop. At, you can select suitable cutting mills with optimised alignment and high torque. Our experienced specialists will be happy to show you which other criteria are relevant in the course of an individual consultation.

You will find these and other types of cutting reamers on

  • Cutting mills
  • Cutting mills with product-specific rotational speeds
  • Cutting mills with spiral or parallel rotors
  • Models with V-cut or cross-shear cutting rotors

Typical sample materials for cutting mills in laboratory or industry

Whether hard, medium-hard or soft materials, whether elastic or fibrous substances, with a cutting mill you can grind and homogenise a wide variety of materials. Even materials containing solids and moist materials can be processed as required with the right laboratory grinder.

  • When processing textile materials or leather, it is necessary to carry out chemical analyses beforehand. To make this possible, high-performance cutting mills are required that are characterised by a high degree of functionality.
  • In food inspection, it is indispensable toregularly check the composition of foodstuffs. Without a high-quality cutting or laboratory mill, it is not possible to achieve precise results.
  • In agriculture, straw, hay and dried plants are subject to constant quality controls. Here, too, suitable cutting tools are indispensable.
  • In forensic science, a wide variety of substances have to be examined, also with a view to preserving evidence. Choose the most suitable cutting or laboratory mill from the portfolio.

Finding the right cutting mill: Criteria for selection

You will find the right cutting mill for every need and every industry in our range. We will be happy to advise you in detail and help you with your product selection. Among other things, the following criteria are important when making a purchase:

The speed of rotation

The higher the rotational speed, the easier it is to draw the ground material into the laboratory mill. High rotational speeds are particularly advantageous for fibrous, porous or elastic materials that need to be ground. Let the team of experts show you the other advantages of high-speed cutting mills.

The rotor design

Depending on the material to be shredded, either spiral or parallel rotors are advantageous. The so-called cross-shear cut rotors also provide first-class service for certain substances. When buying, also pay attention to whether one or more rotors are to be present in the device. If you have any questions, please do not hesitate to contact us.

The quality of the blades

In classic cutting mills, which are primarily intended for domestic use, the blades tend to be soft in terms of their material composition. For use in laboratories and industry, the design of the blades should be as hard as possible and extremely robust. Some cutting mills are equipped with several knife units positioned one above the other in order to generate even finer results or to speed up the grinding process.

The sieve variants

After cutting, the ground material is transferred to a sieving device. Depending on how far the ground material is to be crushed or pulverised, the sieving device must also be designed. At you can choose between different degrees of fineness and material compositions.
