Maintenance Of Thickeners In Mineral Processing Plants

Maintenance of the thickener in a mineral processing plant is crucial. A malfunction can cause a complete plant shutdown. The thickener is an essential dewatering device in the mineral processing plant’s production process.

Maintenance of thickeners in mineral processing plants

1. Precautions when driving or parking

To ensure the thickener works properly, the motor should be started before feeding the ore, and the ore should be fed after the thickener is running. When stopping, feeding must be stopped before parking. If a stoppage is necessary due to special circumstances, feeding must be stopped immediately. The scraper frame should be quickly raised or the discharge rate increased to prevent the scraper from being submerged in the concentrated slurry. The continuity and uniformity of feeding and unloading operations must be ensured.

2. Routine maintenance of the thickener

In daily work, it is necessary to frequently check the feed concentration, concentrated product concentration, and overflow water quality of the thickener to ensure that they meet production requirements. In practice, the concentration of the concentrated product can be adjusted by controlling the discharge speed. However, when adjusting the discharge concentration, care must be taken to prevent an increase in solid loss during overflow and to ensure that the overflow water quality meets the requirements.
