2. GENERAL DESCRIPTION
The LM2000 is a laboratory machine, which is suitable for pulverizing and
homogenizing hard and brittle materials in the dry and wet state.
It is used for fast pulverizing.
The closed milling pulverizing system guarantees complete recovery of the samples.
Final finenesses of down to 20-40 μm can be achieved, depending on the milling time
and the specific properties of the sample material. The optimum filling of a LM2000 is
around 1-1.3 Liters of sample material.
The sample quantity should not be less than 25% of the bowl volume.
The puck may otherwise damage the bowl.
The bowl, puck and lid must always be made of identical material.

3. TECHNICAL FEATURES
3.1. CONSTRUCTION
The housing of LM2000 is made of steel plate with powder coated RAL5005 paint.
Protective equipment
The milling chamber of the LM2000 is safely closed by an electrical safety switch.
Starting of the machine is possible only when:
- power is connected;
- air pressure is sufficient;
- the emergency switch is not activated;
- all parameters are given to the digital program of the machine;
- There is a bowl inside of the machine when using the automatic program;
- Hood is locked;

4. INSTALLATION
4.1. UNPACKING
Before the installation, carefully examine the delivery for possible damage or missing
parts. Open the crate and take the machine out of the box. Check that the machine
has not been visibly damaged during the transport.
Please keep the packing material for the duration of the guarantee period. In case of
a complaint and return of the machine in unsuitable packing material, your guarantee
claim will be lost.
Check that the mains cord is compatible with the local standard.
If any kind of damage occurred during transport, immediately make a complaint to
the carrier. Any incorrect delivery or missing parts should be reported to the
distributor.
4.2. SELECTING THE RIGHT PLACE
When selecting the right place for the machine, please consider the following:
- Put the device on smooth, horizontal and stable place.
- Leave enough space beyond the device for normal air circulation, min. 200 mm at
the back of the machine.
- Leave enough space around the device, that you will easy control and maintain it.
- Don’t use the device in surroundings, where there are fast temperature and humidity
changes. Also avoid places exposed to direct sunlight and places nearby heating
devices.
- Avoid places, where the possibility of shocks and vibrations exists.
Note: The machine should not be placed so, that it is difficult to pull out the
cord plug from mains power supply.
4.3. CONNECTING THE POWER CORD
The correct voltage and frequency for the LM2000 are given on the name plate.
Ensure that these values correspond to the available power supply system.
To avoid interference from noise, surges and spikes, a dedicated line is preferred. If
no such line is available, avoid lines to which powerful electric motors, refrigerators
and similar devices are connected.
The power can be turned on and off by the emergency switch, located on the front
cover at the right side of the machine. Light in the switch indicates, when the power is
on.
Note that when power is lost the saved programs will be lost!

4.4. ENVIRONMENT CONDITIONS
The machine has been built for operating in laboratory environment. Therefore the
environmental conditions should be the following:
- Temperature from +5C to +40C
- Humidity up to 85% RH, non-condensing

5. INSTRUCTIONS FOR USE
5.1. OVERALL VIEW
The LM200 has a couple new features:
•An improved air bellow system
oThe old machine released the bellow into rest position, in some cases this meant that
the bowl can’t be easily removed as the air bag was in the way.
The new system sucks the air bag to its smallest size so the bowl can be easily
removed.
•The overall footprint is decreased so a machine now fits onto an Europallet.
•The touchscreen has been moved from the hood to the side of the machine.
oThis prevents the cables wearing out over time.
•The machine now exist of an top and bottom half.
oRemoving the top half makes the inside easily accessible for maintenance.
•There is a new system for locking the lid.
oThere is an pneumatic magnet which resides in the framework and locks into the
hood. The previous connection could break over time and when not aligned properly
it wouldn’t close.
