Plastometer PL2000

Overview

The Coal Plastometer PL2000 is a fully automatic system for determination of fluidity of coal by the Gieseler method according to ASTM D 2639 and ISO 10329 Standards.Both methods described in the Standards give a relative measure of the plastic behaviour of coal when heated at constant rate, under prescribed conditions.Fluidity of coal is obtained applying a constant torque on a stirrer placed in a crucible loaded with the coal, heating the crucible in a molten solder bath furnace and recording stirrer movement on a dial drum graduated into 100 divisions, D.D.P.M. (Dial Division per Minute) in relation to increase of temperature.

Description
Plastometer PL2000

The Coal Plastometer PL2000 is a fully automatic system for determination of fluidity of coal by the Gieseler method according to ASTM D 2639 and ISO 10329 Standards.Both methods described in the Standards give a relative measure of the plastic behaviour of coal when heated at constant rate, under prescribed conditions.Fluidity of coal is obtained applying a constant torque on a stirrer placed in a crucible loaded with the coal, heating the crucible in a molten solder bath furnace and recording stirrer movement on a dial drum graduated into 100 divisions, D.D.P.M. (Dial Division per Minute) in relation to increase of temperature. All the analysis procedure, even up and down movement of the crucible, is automatic: the Plastometer PL2000 operator needs only to mount the crucible and to start the system.
