Vital spare parts recommendation

A breakdown on a thickener can be critical for the operation of the mine site. Having a reliable parts supply on hand is essential to your operations. Some thickener spares are custom manufactured and thus can have longer lead times. We, therefore, recommend stocking the following vital components to ensure the optimal functionality and availability of your thickener:

Guide blocks
Slew bearing
Gearbox/s
Steady bearing
Hydraulic controls and valves
Instruments

Rake mechanism

The rake mechanism is used to move the settled solids (also called the slurry) toward the center of the tank where they can be removed. The rake mechanism consists of a series of rakes that are suspended from multiple rotating arms. As the arms rotates, the rakes move through the slurry and push them toward the center of the tank. Some of the main components are:

Driveshaft
Pickets
Steady bearing*
Struts and tie rods
Slide bearing
Guide blocks*
Rake arms and blades

*Vital spare part

Drive unit

The thickener drive unit is the mechanism that powers the movement of the rake mechanism in a thickener. The drive unit is typically located at the top of the thickener tank and has a robust design to handle significant hours of operation. This design allows for ease of service and replacement of spares. Below are some of the common spares;

Gearbox*
Pinion
Split/full slew bearing*
Hydraulic cylinder
Support tower
Roller bearings
Hydraulic motor*

*Vital spare part

Instrumentation

Instruments are used to measure parameters for safe operation and control of the thickener, including measurements of the feed density, overflow clarity, feed flow rate, rake height and solid settling. The below instruments are necessary for your thickener:

Rake torque indicator
Bed mass sensor
Bed level probe
Rake height indicator
Rake height limit switch

Hydraulic unit

The hydraulic power unit (HPU) is a mechanical device that uses hydraulic pressure to transmit power to the drive unit and force the rake to lift. The HPU is an integral part of the thickener drive system, below are some of the common spares:

Control/relief valves
Hydraulic motor*
Bell housing
Rake drive/lift pump
Switches
SMART rake lift**
Hose Kit

Feed system

The feed system comprises a critical set of components that have a significant impact on the overall thickener performance by ensuring the feed material is properly conditioned before being introduced to the thickener. Major feed stem components include piping, feedwell, the flocculant distribution system and any components fitted to increase feed dilution. Some of the standard spares found in the feed system:
