Abstract
A treatment machine has a treatment drum mounted in a housing and rotatable by means of an adjustable drive. It is intended particularly for the treatment in batches of a bulk material with differing, changing humidities, treatment temperatures and distributions of the bulk material in, and on the circumference of the treatment drum. The treatment drum is mounted by means of at least two axially spaced bearing rings. Each bearing ring has movable, hydrostatic support elements, distributed evenly around the circumference of the treatment drum, and arranged between a contact surface on the treatment drum and the housing. Each support element has two parts which are able to be displaced in radial direction to each other up to a final position and is supported on the housing via an adjustably elastic intermediate member. Means are included for feeding a fluid under pressure equally to the support elements, and a device is provided to measure the dynamic load on the housing through imbalance of the treatment drum, from which a signal is derived to regulate the drive.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
