Factors to Consider When Designing Thickening Equipment

The gravity Thickening Equipment concentrates the suspended solids in the slurry. How to design such a device? The golden machinery factory explains to you.

These slurries are typically introduced into the center of the tank and allowed to thicken to the desired density. The key component of any thickener is the feed port, which has the following features:

1. Control energy and momentum dissipation; 2. Degasing the feed; 3. Feed dilution (if needed); Optimize flocculation conditions; The feed stream is evenly distributed into the concentrator. The uneven distribution of the feed to the thickener also results in uneven deposition of the coarse solids, resulting in the formation of islands on the thickener floor. As a result, the squat arm fails in this area and the concentrator drive encounters a resultant torque peak.

Consider the downstream factors of design:

The design of the slurry processing system downstream of the concentrator varies greatly from application to application. For example, the surface treatment design of thickened tailings should consider the following parameters: 1. There is a new dam construction, and if it sinks, it contains thickened tailings.

Pumping requirements for high viscosity thickened tailings from processing plants to water storage sites; Potential capacity of the water level; Slurry distribution over time to optimize disposal site capacity; Site environmental requirements (climate, surface water, soil, etc.); Customer preference (ie aversion to volume pump and concentrator automation requirements)

The choice of thickening equipment is based on feed characteristics and standard laboratory scale testing and experience. It is considered that the downstream use of the underflow is minimal, since it is always applicable that the sedimentation slurry (Newton) has no apparent viscosity. On the other hand, pasty thickeners can be improperly designed without regard to the rheology of the downstream process.
