Superior Cutting Mill engineered to reproducibly grind volumes from 30g of up to 30 kg/h.

Method of operation

The Model CM500 Cutting Mill is used by Laboratories and processing Companies to granulate solid materials such as waste or wood and thermoplastics. The material to be processed falls into the cutting chamber of the CM500 via a guide chute and is shredded by cutting between rotating and fixed knives until it passes an attached sieve as ground product. The sieve extends over the lower half of the grinding chamber and is easily exchanged. Final particle size is determined by the selected sieve perforation aperture.

Sieve dimension

( free open surface) must be large in order to obtain:

• a high throughput
• a low heat creation
• a homogeneous result.

No other Cutting Mill is easier to clean then the CM 500 Cutting Mill. When the grinding process is finished the Front door and the Infeed Hopper can be opened sidewise and the milling chamber is fully accessible for quick and easy cleaning in order to perform a fast and systematic cleaning of the grinding tools.

Grinding

The Cutting Mill is the first machine in a sample prep. Laboratory of today when it comes to sample prep. 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 100mm and a total batch of up to 30kgs per hour (volume depending on the characteristic of the samples) can be ground down to 1,00 mm or finer depending on the product.

High operator convenience and maximum safety

Maximum Grinding performance and maximum safety is important for Laarmann Mills. Due to two integrated safety switches (door and collector) the machine can only be started when the “Easy Lock Cover “ is closed and the Sample collector is inserted properly.

The Infeed Hopper as well as the housing of the CM500 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.         

CM500 Benefits and applications

Bottom sieves

A full range of bottom sieves is available in various sizes

The size of the bottom sieve is important in order to decrease the heat creation during the grinding and to increase the capacity.

The sieve dimension is 230mm by 135mm which 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 and receive a homogeneous result.

Performance features CM500
