Cutting Mill working principle

The LAARMANN CM300 Cutting Mill is a reliable, high-performance laboratory cutting mill designed to effectively reduce soft, fibrous and medium hard materials. With applications in intensive research, quality control, and pilot plant settings, the CM300 offers accurate and consistent reduction of material size through its high efficiency. The process involves a high-speed rotor with hardened precision cutting blades that provide excellent shearing forces. The use of fixed knives inside the housing ensures a scissor like cutting effect. The material to be processed enters the cutting zone by way of a specially designed guided hopper, with further reduction until they pass through the bottom sieve. This milling process uses an adjustable sieve system to give the best control over the particle size.

How a Cutting Mill Works

The material to be processed enters the milling chamber through the feed hopper; a feeding device may be present for material control. Here, the rotating blades cut, shear, and impact the material while being opposed by the stationary knives to achieve maximum size reduction. The particles are gradually reduced until they are able to pass through the mesh or screen which ensures even results. The final particle size is defined by the screen aperture. Adjusting the blade setting or changing the screen enables particle size variation.

Cutting Mill control panel

The CM300 has an inbuilt control panel included as standard equipment. This allows full control of rotor speeds and cycling time for optimum machine performance. The controls can be adjusted based on the material being processed, and the CM300 allows digital readings and pre-set programs to be used for ease of operation.

CM100 Cutting Mill FAQ (Frequently Asked Questions)

Laarmann cutting mills are designed for a wide range of materials including plastics, rubber, wood, biomass, textiles, fibrous and medium-hard substances.

Final particle size depends on the selected bottom sieve aperture. Smaller apertures produce finer particles, while larger ones provide coarser output.

These mills feature easily accessible chambers and removable blades, enabling efficient cleaning and reduced downtime.

All models include integrated safety switches and ergonomic design to prevent operation unless covers are securely in place.

Yes. On request most models can be adjusted for continuous grinding with consistent throughput.
