Gieseler apparatus for determination of plastic properties of coal.

Determines the flowability of coal plastic mass during slow heating at constant speed and constant torque.
torque. The apparatus is fully automated and with the help of a programme provides
retort movement, whereby the initial temperature of the test
can be set by the operator depending on the characteristics of the coal being tested. The apparatus
is equipped with two separate furnaces for increased productivity. The entire test process is displayed on the monitor and stored in a database. A report with all the data and the temperature-dependent yield curve can be
can be printed. The report also contains: standard number and name; sample (specimen) number and data sheet; test date; operator name; maximum yield and Log of maximum yield; softening temperature; maximum yield temperature; curing temperature; plasticity interval; heating rate and initial test temperature.
