Safety instructions
You, as the operator, must ensure that the persons instructed to work with the SK 100:
*have noted and understood all the regulations for the safety area,
*know all instructions for action and regulations of the target groups relevant to them before work is commenced,
*have access to the technical documentation at all times and without problem,
*that new personnel is familiarised before commencement of work on the SK 100 with the safe and proper handling either by a verbal introduction from a competent person and/or by means of the present technical documentation.
*Improper operation can result in personal injury and damage to property. You are responsible for your own safety and that of your personnel.
* |
Ensure that no unauthorised persons have access to the SK |
|
100. |
For your own protection, make sure that you are given confirmation that your personnel have received instruction in use of the SK 100. You will find a draft of a related form after the chapter on safety.

Technical Data
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.
Do not make any modifications to the machine and use only RETSCH a accessories.
Failure to comply will invalidate the CE declaration and guarantee.
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:
ashes |
drugs |
ores |
animal feed |
rocks |
glass |
resins |
potassium |
coal |
coke |
grains |
artificial resins |
minerals |
pellets |
salts |
slags |
bricks |
bauxite |
gypsum |
pyrites |
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.

Feed grain size max. 20mm
Collecting vessel capacity
5,000 ml or 30,000ml
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 LpAeq = 86 dB(A) 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
Type of protection
