What is a cutting mill used for?

A cutting mill is a sample preparation machine that reduces the size of dry, cuttable materials by shearing and cutting between rotating and fixed knives to produce uniform particle sizes.

Cutting Mills

Q: What materials can cutting mills process?

Cutting mills are suitable for a wide range of materials including plastics, rubber, wood, paper, textiles, biomass, and many industrial dry samples. Defined particle sizes can be achieved via interchangeable bottom sieves.

Q: How do I choose the right cutting mill?

Choose based on feed size, throughput capacity, and desired final particle size. Smaller models are ideal for low-volume or research labs, while larger models are suited for industrial throughput.

Q: Can cutting mills be cleaned easily?

Yes. LAARMANN cutting mills offer easy access to the grinding chamber and sieves for quick cleaning and maintenance.

Q: What determines the final particle size in a cutting mill?

Final particle size is determined by the bottom sieve perforation size and mill configuration. Smaller sieve openings result in finer particle sizes.

High-Performance Cutting Mills for Dry Material Size Reduction in Laboratories & Industry

LAARMANN Cutting mills are of the art sample preparation machines for cuttable materials. The system are suitable for the coarse and/or fine grinding of any dry substance because of the availability of several differrent sizes bottom sieves. The user will benefit from the high rate of homogenized samples which is collected in the various collectors which are available.

The material to be processed falls into the cutting chamber of the Cutting Mills via a guide chute. Than the product is shredded between rotating and fixed knives. The product passes the sieve as soon as its reached the desired size. The sieve extends over the lower half of the grinding chamber and can be changed easily. Final particle size is determined by the selected sieve perforation aperture.

When the grinding process is finished the grinding chamber is fully accessible for quick and easy cleaning by unscrewing two hand screws and folding back the infeed hopper.
