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.
