Conventional Gravity Thickener

High rate thickener units are provided in sizes ranging from 5' to 250' in diameter, and can accommodate drive head torques of up to 4 million foot pounds. They are available in shaft or cage driven models.

Shaft drive thickeners can be truss or beam supported for heavy duty applications. A heavy duty drive unit with precision bearing and gear transmits torque through a steel center shaft to the rake arms. Equipped with Torkmatic drive control, the drive unit senses increasing torque and overload conditions, and will sound an alarm to alert an operator. If excessive torque is sensed, the drive control will shut down the unit until conditions permit safe operation. The shaft drive unit is equipped with a rake lifting device, providing added mechanism protection and operation flexibility in an overload condition.

Cage drive units are suitable for larger thickeners and can provide the torque needed in heavy-duty thickening applications. The cage drive is supported by a steel center column. These units transmit torque from a fabricated steel drive unit with precision bearing and gear through a center cage of box truss construction. Cage drive units are also equipped with Torkmatic drive control and can be designed with lifting capabilities.
