Centrifugal Shifter

APPLICATION

Centrifuges are heavy duty, three point suspended, under driven, Centrifuges which are suitable for the Chemical, Pharmaceutical, Textile and other industries.

CONSTRUCTION DETAILS

SHAFT AND BEARINGS :

The main shaft is of suitable steel and is amply proportioned to withstand the loads imposed on it by the centrifugal forces caused by all normal uneven distribution of the charge in the basket. The bearings supporting the main shaft are heavy duty ball/roller bearings which have a statistical life of 5000 or more running hours. These bearings are grease lubricated. Grease retainers are fitted to ensure long lubricating intervals.

BASKET :

The basket shell which is normally perforated (but can also be without perforations if so required by the client) is adequately thick to withstand the loads caused by the centrifugal forces developed by the charge in the basket. The shell as well as the top flange can be supplied in M.S. rubber-lined or S.S. (AISI 304 or 316). The basket bottom plate is of M.S. and lined at the inside surface by rubber or 16 swg S.S. as applicable. The basket hub is of close grained cast iron.

VIBRATION SUSPENSION :

These centrifuges are fitted with heavy duty three point Pendulum suspension for vibration absorption. Hemispherical bearings are used at both the ends of
the suspension rods.

DRIVE SYSTEM :

The drive system consists of a 415V/3 Ph/50Hz squirrel cage induction TEFC electric motor which drives the basket through V-belts. The motor is mounted at the basket casing (outer drum) and there is provision for tensioning the belts. All models are fitted with Centrifugal clutch pulley at the motor shaft. These clutches are heavy duty types designed specially for centrifuge duties.
