Purpose for which this system has been designed
This Operating Manual contains the information required for operation of the products de-
scribed here, for the purpose for which they have been designed. This Operating Manual
is intended to be used only by technically qualified staff.
“Technically qualified staff” is defined as those persons who – as a result of their training;
their experience; the instructions which they have received; as well as their knowledge of
the relevant standards, regulations, accident-prevention regulations, and conditions of
product operation in the company
– have been authorized by the person responsible for
the safety of the company facilities to carry out the activities and actions required for op-
eration of the equipment described below, and who can recognize and prevent any possi-
ble dangers arising from such operation (this definition of technically qualified staff has
been provided in IEC 364).
The User must by all means observe the requirements and limit values, as well as all
safety instructions, given in this Operating Manual. Any use of this device not in conformity
with these stipulations shall be considered to be in violation of the use for which this system
was intended. If this device must be operated under special conditions, or with special
modes of operation, then this shall be authorized only after consultation with the Manufac-
turer, and after obtaining his prior and express approval.
The fineness of grind can be determined according to the Blaine technique and is indicated
as the specific surface (Blaine value). The semiautomatic apparatus serves exclusively for
determination of the specific surface of powders, and for fast analysis of characteristic
operational values. The Blaine value is not a measure of granulometric distribution. The
Blaine value can therefore be used only to a limited degree to evaluate the suitability of a
type of test material for a certain use.
Caution
The instructions given in this Operating Manual apply only for the cor-
rect application of the apparatus. In order to correctly conduct tests, the
User and Operator must observe the specific standards that apply for
the testing being conducted.
Please take the time to read this Operating Manual carefully. It describes how you safely
operate the machine.
