General description
Tumbler Systems are able to mechanically test samples of coke, coal, iron ore, iron ore pellets according to several standards.
These systems are electro-mechanical units where the sample is placed to be tumbled at specific revolution speed for a specific number of revolutions. The above mentioned test conditions together with the dimension of the tumbling unit are prescribed in the standards.
The mechanical units are provided with high quality gear motors and safety cages to comply with the common safety rules in use. A switch is installed on the door of the cage to immediately stop any rotation of the tumbler in case of opening of the cage during the run of the test.
On TB 7000 units, a positioning function allows to rotate the tumbler at slow speed to help the operator on loading and unloading of the sample in the tumbler. The control cabinet connected to the mechanical unit is equipped with a pre-set counter to set up the number of revolutions at which automatically the test is stopped.
TB 7000
According to: ASTM D 3402, ISO 3271, ISO 11256, ASTM E 279, ISO 556, IS 6495, IS 1354
Tumbler device for coke, iron ore and sinter.
Geared motor unit driven by frequency converter. Number of revolutions is pre-set on a digital counter showing remaining revolutions to the end of tumbling.
Automatic stop at end of test is provided. The unit is protected by a safety cage surrounding the equipment with an opening door.
A safety switch is provided on the cage door. The Equipment can be supplied in different configuration according to the specific standard requirement (see table below).
