Torque overload in a gravity sludge thickener can be caused by ________

Torque overload in a gravity sludge thickener can occur when the sludge removal rate is too low. In this scenario, the accumulated sludge can lead to increased hydrostatic pressure and density within the thickener. If the removal rate does not keep pace with the rate at which sludge is being fed into the unit, it can result in an excess amount of material that the thickener is expected to process. This excess buildup causes the machinery responsible for agitation or movement within the thickener to work harder than designed, leading to a torque overload condition.

Maintaining an appropriate sludge removal rate is crucial for the optimal operation of a gravity sludge thickener, as it ensures that the system can handle the volume of incoming sludge without becoming overloaded.
