CM4000 Cutting Mill

The CM4000 Cutting Mill is used by laboratories and processing companies for cutting granulate solid materials such as waste, wood and thermoplastics.

  • Quick and easy to clean
  • Full range of bottom sieves
  • The CM4000 can handle samples of up to 200Kg/h

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.

High operator convenience and maximum safety

The Cutting Mill is the first machine in a state of the art sample preparation. laboratory when it comes to sample preparation of cuttable materials.

This system is suitable for the coarse and fine grinding of any dry substance, typically samples with a feed size of up to 350mm and a total batch of up to 200 kgs per hour (volume depending on the characteristic of the samples) can be ground down to 1 mm or finer depending on the product.

Maximum Grinding performance and maximum safety is important for LAARMANN Mills. Due to the integrated safety switch the machine can only be started when the “Easy Lock Cover“ is closed and the grinding chamber cover is inserted properly.

The Infeed Hopper as well as the housing of the CM4000 is made from solid steel.

The ergonomic design of the machine and the positioning of the funnel and the starter box require a minimum space in the laboratory.

Bottom sieves

The size of the bottom sieve is important in order to decrease the heat creation during the grinding and to increase the capacity.  This assures a large open surface which is essential for the cutting process to:

  • Obtain a high throughput
  • Have a low heat creation during the grinding process
  • Receive a homogeneous result
