3 Technical Data
3.1 Intended use
This device has not been designed as a production machine or for continuous operation, but
rather as laboratory device for operation in an 8-hour single shift.
The
ABP 250 is suitable for grinding medium to hard substances as well as brittle and hard
ductile materials. The final fineness that can be achieved can be up to 2 mm and less
depending on the feed material.
The maximum feed size is <120 x 90 mm.
The following materials are examples of those that can be ground in the
ABP 250 :
Concrete, ores, rock, glass, ceramics, coal, minerals, slag, cement clinker etc.
The performance data, throughput and the final fineness level that can be achieved depend on
the breaking properties and degree of hardness of the sample material and on the gap width
that has been set. They can only be empirically calculated.
The Retsch applications laboratory will be happy to provide any further information you require.
Any other use is considered to be improper and can lead to damage to property and even to
personal injuries.
3.2 Protective Equipment

This device may only be started once the door has been closed and the collecting receptacle
has been inserted in the base frame.

A limit switch behind the collecting receptacle prevents the device being started in an unsafe
state.

Pulling the collecting receptacle out results in the machine stopping immediately.

The door can only be opened once the collecting receptacle has been removed.

The motor protection switch turns the drive motor off if there is a blockage in the jaws.
3.3 Gap width
Gap width: 0 to 30 mm, adjustable using the threaded spindle
3.4 Degree of Protection

IP 54
3.5 Emissions
Noise levels:
The noise levels are influenced by the properties of the sample material.
Example:
Feed material: Marble pebbles (< 50 mm)
Gap width: < 1 mm
Final particle size < 4 mm
Grinding chamber
filling level: ~ 65 %
