Machine type designation: SM 300
The heavy-duty SM 300 cutting mill serves to grind flexible, hard-ductile and
fibrous products and product mixtures in batches or continuously. The SM 300 is
not designed for grinding wet or moist materials. The special shape of the cutting
tools in conjunction with the drive enable fast, efficient grinding without adversely
affecting the material being processed.
The following are the special characteristics
The new heavy-duty SM 300 cutting mill is convincing in difficult size reduction
tasks where other cutting mills fail. The high torque of the new 3 KW drive with
additional auxiliary flywheel mass allows a particularly effective preliminary size
reduction of heterogeneous material mixes, such as waste or electronic
components. Analytical fineness is usually attained in one step. The cutting mill is
used successfully for a great variety of other materials also, whereby the grinding
stock is warmed up only to a low degree during the grinding process so that the
mill is also suitable for grinding temperature-sensitive materials.
A further innovation is the cutting mill’s broad, freely selectable speed range from
700 to 3,000 rpm. The large selection of sieves, hoppers and collecting vessels
allow the mill to be adapted to individual tasks.
– fast, gradual size reduction by 18 cutting plates spaced in a helical pattern
along the circumference of the rotor
– parallel section rotor
– cutting tools which are made of high-quality materials and can be reused
over and over again
– high level of operating convenience due to central lock and operator panel
– consistent operational reliability in all user-relevant equipment components
– versatility in use due to variant designs and a large number of accessories
– powerful size reduction thanks to the 3-KW moto r’s high torque
– perfect adaptation to the material being ground thanks to the variable speed
from 700 to 3,000 rpm
– optimised cutting effect due to the double-acting cutting bars
– very fast cleaning thanks to hinged enclosure with smooth surfaces and
push-fit rotor
– defined final fineness due to bottom sieves with aperture sizes 0.25 - 20 mm
