Machine type designation: SK 100
Application with proper use
SK 100 standard
For uses where primarily the same materials are to be ground in larger
quantities and it is not absolutely necessary to open the door after every
grinding operation to clean the grinding chamber.
SK 100 comfort
For uses where always different materials are to be ground and it is necessary to open the door after every grinding operation to clean the grinding
chamber.
This unit is not designed as a production machine, but as as laboratory device intended for 8 hours single shift operation.
Both types crush medium-hard to hard and brittle materials with a hardness of about 6 according to Mohs.
They are conceived especially for crushing the following materials:
and many other, similar materials.
The achievable end fineness depends on the hole width of the bottom
sieve and the grinding properties of the material to be ground. In favourable cases, finenesses of <100µm can be achieved.
For further information, our application laboratory is at your disposal.

Noise emissions
Noise measurement according to DIN 45635-31-01-KL3
Noise data are dependent on the fracturing properties fo the
product beeing ground.
Example:
Sound power level: LWA = 95 dB(A)
Workplace-related emission L
= 86 dB(A)
pAeq
Operating conditions:
Sample material: quartz, grain size < 3 mm
Filling ratio of grinding chamber: feeding quantity each until
motor rated power is reached.
Noise data
Workplace-related emission at a distance of 1 m:
72 to 80 dB(A) as a function of the material being ground
